This implements the API defined in <linux/decompress/generic.h> which is
used for kernel, initramfs, and initrd decompression. This patch together
with the first patch is enough for XZ-compressed initramfs and initrd;
XZ-compressed kernel will need arch-specific changes.
The buffering requirements described in decompress_unxz.c are stricter
than with gzip, so the relevant changes should be done to the
arch-specific code when adding support for XZ-compressed kernel.
Similarly, the heap size in arch-specific pre-boot code may need to be
increased (30 KiB is enough).
The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and
memzero() (memset(ptr, 0, size)), which aren't available in all
arch-specific pre-boot environments. I'm including simple versions in
decompress_unxz.c, but a cleaner solution would naturally be nicer.

In userspace, the .lzma format has become mostly a legacy file format that
got superseded by the .xz format. Similarly, LZMA Utils was superseded by
XZ Utils.
These patches add support for XZ decompression into the kernel. Most of
the code is as is from XZ Embedded <http://tukaani.org/xz/embedded.html>.
It was written for the Linux kernel but is usable in other projects too.
Advantages of XZ over the current LZMA code in the kernel:
- Nice API that can be used by other kernel modules; it's
not limited to kernel, initramfs, and initrd decompression.
- Integrity check support (CRC32)
- BCJ filters improve compression of executable code on
certain architectures. These together with LZMA2 can
produce a few percent smaller kernel or Squashfs images
than plain LZMA without making the decompression slower.
This patch: Add the main decompression code (xz_dec), testing module
(xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool,
and documentation. The xz_dec module is enough to have a usable XZ
decompressor e.g. for Squashfs.

Turns out this is an arguable defect in the script.
The MAINTAINERS entry for mm is:
MEMORY MANAGEMENT
L: linux-mm@kvack.org
W: http://www.linux-mm.org
S: Maintained
F: include/linux/mm.h
F: mm/
There's a maintainer entry, but no named individual, so the script doesn't
use git history via --git-fallback.
This is also a defect for MAINTAINERS with status entries marked "Orphan"
or "Odd fixes".
The script now checks a section for any "M:" entry and that an "S:" entry
is supported or maintained. If both those conditions are not satisified,
use --git-fallback as appropriate.

It was messy to follow the primary flow of code execution with the

This patch fixes a segfault in modpost that is observed when the gold
linker is used to link the input objects.
The problem is that reloc_location (modpost.c) is computing the
address of the relocation target incorrectly. Here, elf->hdr points
to the beginning of the ELF file in memory, sechdr points to the
relocation section header, section is the index of the section
being relocated, and sechdrs[section].sh_offset would be the offset
of that section, relative to the beginning of the ELF file. Adding
elf->hdr + sechdrs[section].sh_offset gives you the address of the
beginning of the section, and adding r->r_offset to that gives you the
address of the location to be relocated. You do not need to subtract
sechdrs[section].sh_addr from that -- the result of this is an address
outside the file, and causes the segfault when addend_386_rel tries to
dereference it.
This bug is not observed when GNU ld is used to link the inputs. The
object file ubuntu/omnibook/omnibook.o is the result of an ld -r of
several other files. When GNU ld does an ld -r, it sets the vaddr
field for each section to 0, but gold lays out the section addresses
sequentially instead:
Section Headers:
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
[ 0] NULL 00000000 000000 000000 00 0 0 0
[ 1] .text PROGBITS 00000000 000034 004794 00 AX 0 0 4
[ 2] .data PROGBITS 0000b9d0 0047c8 0009c0 00 WA 0 0 4
[ 3] .bss NOBITS 000162f8 005188 00013c 00 WA 0 0 4
[ 4] .rodata.str1.1 PROGBITS 00004f2d 0052c4 001b1a 01 AMS 0 0 1
[ 5] .init.text PROGBITS 00004794 006dde 0005fa 00 AX 0 0 1
[ 6] .exit.text PROGBITS 00004d8e 0073d8 00018a 00 AX 0 0 1
...
So the bug in the tool remained undiscovered because the section's vaddr
always happened to be 0.

This patch adds support for linking device tree blob(s) into
vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking
.dtb sections into vmlinux. To maintain compatiblity with the of/fdt
driver code platforms MUST copy the blob to a non-init memory location
before the kernel frees the .init.* sections in the image.
Modifies scripts/Makefile.lib to add a kbuild command to
compile DTS files to device tree blobs and a rule to create objects to
wrap the blobs for linking.
STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to
create wrapper objects for the dtb in Makefile.lib. The
STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the
STRUCT_ALIGNMENT definition.
The DTB's are placed on 32 byte boundries to allow parsing the blob
with driver/of/fdt.c during early boot without having to copy the blob
to get the structure alignment GCC expects.
A DTB is linked in by adding the DTB object to the list of objects to
be linked into vmlinux in the archtecture specific Makefile using
obj-y += foo.dtb.o

This is an attempt to simplify the expressing printed by kconfig when a
symbol is selected but still has direct unmet dependency.
First, the symbol reverse dependency is split in sub-expression. Then,
each sub-expression is checked to ensure that it does not contains the
unmet dependency. This removes the false-positive symbols and fixed symbol
which already have the correct dependency. Finally, only the symbol
responsible of the "select" is printed, instead of its full dependency tree.

Commit 7db86dc (ctags: usability fix) removed function prototypes from
tags file claiming "It makes no real sense to include function
prototypes".
But it is useful for quickly determining which header file developer
needs to include to fix compilation.
Now if someone wants to remove forward declarations (which I agree are
baggage), write a postprocessing script.

Instead of creating the debian package for the compiling userland,
create it for a userland matching the kernel thats being compiled.
This patch supports all Lenny release architectures,
and Linux-based architecture candidates for Squeeze.
If it can't find a proper Debian userspace it displays a warning,
and fallback to let deb-gencontrol use the host's userspace arch.
Eg. with this patch the following make command:
make ARCH=i386 deb-pkg
will output an i386 Debian package instead of an amd64 one,
when run on an amd64 machine.

cmd_record_mcount is used to locate the _mcount symbols in the object
files, only the files compiled with -pg has the _mcount symbol, so, it
is only needed for such files, but the current cmd_record_mcount is used
for all of the object files, so, we need to fix it and speed it up.
Since -pg may be removed by the method used in kernel/trace/Makefile:
ORIG_CFLAGS := $(KBUILD_CFLAGS)
KBUILD_CFLAGS = $(subst -pg,,$(ORIG_CFLAGS))
Or may be removed by the method used in arch/x86/kernel/Makefile:
CFLAGS_REMOVE_file.o = -pg
So, we must check the last variable stores the compiling flags, that is
c_flags(Please refer to cmd_cc_o_c and rule_cc_o_c defined in
scripts/Makefile.build) and since the CFLAGS_REMOVE_file.o is already
filtered in _c_flags(Please refer to scripts/Makefile.lib) and _c_flags
has less symbols, therefore, we only need to check _c_flags.
---------------
Changes from v1:
o Don't touch Makefile for CONFIG_FTRACE_MCOUNT_RECORD is enough
o Use _c_flags intead of KBUILD_CFLAGS to cover CONFIG_REMOVE_file.o = -pg

Since MIPS modules' address space differs from the core kernel space, to access
the _mcount in the core kernel, the kernel functions in modules must use long
call (-mlong-calls): load the _mcount address into one register and jump to the
address stored by the register:
c: 3c030000 lui v1,0x0 <--------> b label
c: R_MIPS_HI16 _mcount
c: R_MIPS_NONE *ABS*
c: R_MIPS_NONE *ABS*
10: 64630000 daddiu v1,v1,0
10: R_MIPS_LO16 _mcount
10: R_MIPS_NONE *ABS*
10: R_MIPS_NONE *ABS*
14: 03e0082d move at,ra
18: 0060f809 jalr v1
label:
In the old Perl version of recordmcount, we only need to record the position of
the 1st R_MIPS_HI16 type of _mcount, and later, in ftrace_make_nop(), replace
the instruction in this position by a "b label" and in ftrace_make_call(),
replace it back.
But, the default C version of recordmcount records all of the _mcount symbols,
so, we must filter the 2nd _mcount like the Perl version of recordmcount does.
The C version of recordmcount copes with the symbols before they are linked, So
It doesn't know the type of the symbols and therefore can not filter the
symbols as the Perl version of recordmcount does. But as we can see above, the
2nd _mcount symbols of the long call alawys follows the 1st _mcount symbol of
the same long call, which means the offset from the 1st to the 2nd is fixed, it
is 0x10-0xc = 4 here, 4 is the length of the 1st load instruciton, for MIPS has
fixed length of instructions, this offset is always 4.
And as we know, the _mcount is inserted into the entry of every kernel
function, the offset between the other _mcount's is expected to be always
bigger than 4. So, to filter the 2ns _mcount symbol of the long call, we can
simply check the offset between two _mcount symbols, If it is 4, then, filter
the 2nd _mcount symbol.
To avoid touching too much code, an 'empty' function fn_is_fake_mcount() is
added for all of the archs, and the specific archs can override it via chaning
the function pointer: is_fake_mcount in do_file() with the e_machine. e.g. This
patch adds MIPS_is_fake_mcount() to override the default fn_is_fake_mcount()
pointed by is_fake_mcount.
This fn_is_fake_mcount() checks if the _mcount symbol is fake, e.g. the 2nd
_mcount symbol of the long call is fake, for there are 2 _mcount symbols mapped
to one real mcount call, so, one of them is fake and must be filtered.
This fn_is_fake_mcount() is called in sift_rel_mcount() after finding the
_mcount symbols and before adding the _mcount symbol into mrelp, so, it can
prevent the fake mcount symbol going into the last __mcount_loc table.

Some menuconfigs in the Kconfig files have prompts and dependencies.
Currently, streamline_config misses these, and this can cause

I noticed that some Kconfig files have multi line dependencies
that continue with a backslash. Those dependencies on the next
line will be missed by streamline_config.
For example:

tristate "CS89x0 support"
depends on NET_ETHERNET && (ISA || EISA || MACH_IXDP2351 \
|| ARCH_IXDP2X01 || MACH_MX31ADS)
The "|| ARCH_IXDP2X01 || MACH_MX31ADS)" will not be processed.
This patch adds code to handle this case.

Adding commit signers when there is a listed MAINTAINER for a file
can make the output list longer than necessary.
Change the --git default from on to off.
Add a new --git-fallback option (default on) used to add commit signers
only when there is no MAINTAINER for a file.
git history is used when --git-fallback is enabled and the pattern
directory depth is not the same as the file directory depth.
For instance:
X86 ARCHITECTURE (32-BIT AND 64-BIT)
M: Thomas Gleixner <tglx@linutronix.de>
M: Ingo Molnar <mingo@redhat.com>
M: "H. Peter Anvin" <hpa@zytor.com>
M: x86@kernel.org
T: git git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git
S: Maintained
F: Documentation/x86/
F: arch/x86/
If using "./scripts/get_maintainer -f arch/x86/lib/atomic64_32.c", the pattern
for "arch/x86/" does not match the directory depth of "arch/x86/lib"
so the MAINTAINERS entries and git history is used to produce:
$ ./scripts/get_maintainer.pl -f --rolestats arch/x86/lib/atomic64_32.c
Thomas Gleixner <tglx@linutronix.de> (maintainer:X86 ARCHITECTURE...)
Ingo Molnar <mingo@redhat.com> (maintainer:X86 ARCHITECTURE...)
"H. Peter Anvin" <hpa@zytor.com> (maintainer:X86 ARCHITECTURE...,commit_signer:1/1=100%)
x86@kernel.org (maintainer:X86 ARCHITECTURE...)
Luca Barbieri <luca@luca-barbieri.com> (commit_signer:1/1=100%)
linux-kernel@vger.kernel.org (open list)
Luca Barbieri is added because he signed the only commit to
arch/x86/lib/atomic64_32.c during the last year and he meets the
other default qualifications.
--git-min-percent (default:10)
--git-min-signatures (default:1)
If current users of ./scripts/get_maintainers.pl have scripts
that use --nogit that expect git history to be excluded, those
scripts should be updated to include --nogit-fallback or a
.get_maintainer.conf file should be created with --nogit-fallback.

When DYNAMIC_FTRACE is enabled and we use the C version of recordmcount,
all objects are run through the recordmcount program to create a
separate section that stores all the callers of mcount.
The build process has a special file: scripts/mod/empty.o. This is
built from empty.c which is literally an empty file (except for a
single comment). This file is used to find information about the target
elf format, like endianness and word size.
The problem comes up when we need to build recordmcount. The
build process requires that empty.o is built first. The build rules
for empty.o will try to execute recordmcount on the empty.o file.
We get an error that recordmcount does not exist.
To avoid this recursion, the build file will skip running recordmcount
if the file that it is building is script/mod/empty.o.

The C version of recordmcount is compiled to a binary, which will

The file kernel/trace/ftrace.c references the mcount() call to
convert the mcount() callers to nops. But because it references
mcount(), the mcount() address is placed in the relocation table.
The C version of recordmcount reads the relocation table of all
object files, and it will add all references to mcount to the
__mcount_loc table that is used to find the places that call mcount()
and change the call to a nop. When recordmcount finds the mcount reference
in kernel/trace/ftrace.o, it saves that location even though the code
is not a call, but references mcount as data.
On boot up, when all calls are converted to nops, the code has a safety
check to determine what op code it is actually replacing before it
replaces it. If that op code at the address does not match, then
a warning is printed and the function tracer is disabled.
The reference to mcount in ftrace.c, causes this warning to trigger,
since the reference is not a call to mcount(). The ftrace.c file is
not compiled with the -pg flag, so no calls to mcount() should be
expected.
This patch simply makes recordmcount.c skip the kernel/trace/ftrace.c
file. This was the same solution used by the perl version of
recordmcount.

The elf reader for recordmcount.c had duplicate functions for both
32 bit and 64 bit elf handling. This was due to the need of using
the 32 and 64 bit elf structures.
This patch consolidates the two by using macros to define the 32
and 64 bit names in a recordmcount.h file, and then by just defining
a RECORD_MCOUNT_64 macro and including recordmcount.h twice we
create the funtions for both the 32 bit version as well as the
64 bit version using one code source.

base patch to implement 'jump labeling'. Based on a new 'asm goto' inline
assembly gcc mechanism, we can now branch to labels from an 'asm goto'
statment. This allows us to create a 'no-op' fastpath, which can subsequently
be patched with a jump to the slowpath code. This is useful for code which
might be rarely used, but which we'd like to be able to call, if needed.
Tracepoints are the current usecase that these are being implemented for.

In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15),
support to link menuconfig with ncursesw library was added. To compute
the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses. However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.
Add /usr/include/ncursesw to the list of directories that are checked.
With this patch, on my Debian Lenny box with libncursesw5-dev package but
not libncurses5-dev package, I can say "make menuconfig".

Fix this by checking if the kernel source tree is the root of the git or
hg repository. No fix for svn: If the kernel source is not tracked in

If a minimal config did not specify the value
of all choice values, the resulting configuration
could have wrong values.
Consider following example:
config M
def_bool y
option modules
choice
prompt "choice list"
config A
tristate "a"
config B
tristate "b"
endchoice
With a defconfig like this:
CONFIG_M=y
CONFIG_A=y
The resulting configuration would have
CONFIG_A=m
which was unexpected.
The problem was not not all choice values were set and thus
kconfig calculated a wrong value.
The fix is to set all choice values when we
read a defconfig files.
conf_set_all_new_symbols() is refactored such that
random choice values are now handled by a dedicated function.
And new choice values are set by set_all_choice_values().
This was not the minimal fix, but the fix that resulted
in the most readable code.

These are caused by checkpatch incorrectly parsing its internal

a statement block encapsulated in {}'s that also ends with a ';'). Fix
this by properly parsing a statement block.
An example:

+};
+EXPORT_SYMBOL_GPL(dummy);
+
+static int dummy_func(void)

savedefconfig will save a minimal config to a file
named "defconfig".
The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.
The implementation was tested against several minimal
configs for arm which was created using brute-force.
There was one regression related to default numbers
which had their valid range further limited by another symbol.
Sample:
config FOO
int "foo"
default 4
config BAR
int "bar"
range 0 FOO
If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.
This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

There seems to be a kconfig bug due to MODULES not always being
evaluated if no .config is found. Take the following Kconfig as an
example:
config MODULES
def_bool y
config FOO
def_tristate m
With no .config, the following configuration is generated:
CONFIG_MODULES=y
CONFIG_FOO=y
With an empty .config, the following:
CONFIG_MODULES=y
CONFIG_FOO=m
Tristate choice statements can also exhibit the problem, due to having an
implicit rev_dep (select) containing "m".
The problem is that MODULES is never evaluted in conf_read_simple() unless
there's a .config. The following patch fixes this.

I found this issue in a locally patched 2.6.32.x, current kernels have
moved the offending code to an __init function which is skipped by
recordmcount.pl, so the bug is not currently being exercised.
However, I think the patch is still a good idea, to avoid future
problems if _mcount were to ever have its address taken in normal
code.
This is what I originally saw:
Although arch/mips/kernel/ftrace.c is built without -pg, and thus
contains no calls to _mcount, it does use the address of _mcount
in ftrace_make_nop(). This was causing relocations to be emitted
for _mcount which recordmcount.pl erronously took to be _mcount
call sites. The result was that the text of ftrace_make_nop()
would be patched with garbage leading to a system crash.
In non-module code, all _mcount call sites will have R_MIPS_26
relocations, so we restrict $mcount_regex to only match on these.

The 'source' builtin is a bash alias to the '.' (dot) builtin. While the
former is supported only by bash, the latter is specified in POSIX and
works fine with all POSIX-compliant shells I am aware of.
The '$_' special parameter is specific to bash. It is partially
supported in dash too but it always evaluates to the current script path
(which causes the script to enter a loop recursively re-executing
itself). This is why I have replaced the two occurences of '$_' with the
explicit parameter.
The 'local' builtin is another example of bash-specific code. Although
it is supported by all POSIX-compliant shells I am aware of, it is not
part of POSIX specification and thus the code should not rely on it
assigning a specific value to the local variable. Moreover, the 'posh'
shell has a limited version of 'local' builtin not supporting direct
variable assignments. Thus, I have broken one of the 'local'
declarations down into a (non-POSIX) 'local' declaration and a plain
(POSIX-compliant) variable assignment.

the visibility but they do not affect the reverse dependencies in any
way.
The patch introduces additional tracking of the "depends on" statements
and prints a warning on selecting an option if its direct dependencies
are not met.

The initial pass at the generic ABI assumed that wait4() could be
easily expressed using waitid(). Although it's true that wait4()
can be built on waitid(), it's awkward enough that it makes more
sense to continue to include wait4 in the generic syscall ABI.
Since there is already a deprecated wait4 in the ABI, this change
converts that wait4 into old_wait, and puts wait4 in the next
available slot for new supported syscalls, after the platform-specific
syscalls at number 260.

Now that we run scripts/setlocalversion during every build, it makes
sense to move all the localversion logic there. This cleans up the
toplevel Makefile and also makes sure that the script is called only
once in 'make prepare' (previously, it would be called every time due to
a variable expansion in an ifneq statement). No user-visible change is
intended, unless one runs the setlocalversion script directly.

It just hit me.
It's the offset calculation in reloc_location() which overflows:
return (void *)elf->hdr + sechdrs[section].sh_offset +
(r->r_offset - sechdrs[section].sh_addr);
E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

A 'coccicheck' target is added. It can be called with four different
modes. Each one generates a different kind of output, i.e. context,
patch, org, report, according to the corresponding mode to be
activated.
The new target calls the 'coccicheck' front-end in the 'scripts'
directory with the MODE argument. Every SmPL file in the
subdirectories of 'scripts/coccinelle' is then given to the front-end
and applied to the entire source tree.
The four modes behave as follows:
'report' generates a list in the following format:
file:line:column-column: message
'patch' proposes a fix, when possible.
'context' highlights lines of interest and their context in a
diff-like style. Lines of interest are indicated with '-'.
'org' generates a report in the Org mode format of Emacs.

commit 37a8d9f67f tried to combine some
duplicate code and accidentally broke how KBUILD_SYMTYPES worked
This fixes the code to match the original intention by the author who
originally added the code I believe.
The fixes include:
- removing extra whitespaces in the if-statements
- moving the if-statement from around the -r to the -T
- adding a second arg to cmd_gensymtypes to simplify the options passed
to genksyms.
Tested by instrumenting genksyms and seeing what options were passed in
during a make, KBUILD_SYMTYPES make, and when a foo.symref was created.

Quite a few Kconfig symbols contain lowercase letters. The current
checkkconfigsymbols.sh code only contains A-Z in the regexp it uses to
find config symbols in source code, so it comes up with the wrong symbol
to look for in Kconfig files and then generates false positives when it
doesn't find that wrong symbol. For example checking drivers/net
generates a false positive for MAC89 because the the actual config
option is MAC89x0.
Fix this by also adding a-z to the regexp.

/* Reset values of generates values, so they'll appear

*/
if (sym->visible == no && !conf_unsaved)
sym->flags &= ~SYMBOL_DEF_USER;

}
But a menu item which represents an invisible symbol is still
visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER

This changes the default of the option --git-all-signature-types to be
disabled by default.
The effect being, that only certain (currently Signed-Off-By:, Acked-by:
and Reviewed-By:) tags are used to get adresses of potential maintainers.
Motivated is this change by the desire to not 'spam' people unnecessary: A
Tested-By or a Reported-By is not ment as a hint that those people want
to/are able to review patches to the code in question.
In a quest to find resilient statistics for this i came up with this:
I produced a list of all the tag-signers not already covered with a
signed-off/acked/reviewed tag somewhere in the last year of git history.
Those were 650 addresses of "assumed non-developers".
And to check if those "assumed non-developers" are professional
testers/reporters worth cc'ing, i then counted their total appearences
in the git log:
469 were mentioned only once.
123 were mentioned twice.
38 three times
8 four times
5 six times
5 five times
1 eight times
1 fourteen times
I believe this supports my thesis, that the ''non-maintainer-tags'' are
not actively useful for patch-review. (except probably the guy mentioned
fourteen times...)
But of course one could also find arguments to poke holes in this
statistics, for example does this statistic not include code-locality: A
tested-by on a patch that touches some specific piece of code can be more
worth than a signed-off in another part of the tree.
But... let's play it safe and let's err on the "safe" side meaning to not
spam those people when in doubt. We already have the signed-off's and
Maintainers file. So this should be ok. And if need be, the maintainers
can always forward the patch.

When using --git to determine who to send a patch to, get_maintainers will
currently include all signatures. This can include signers that simply
report an issue or test a patch. Signers that use this tag are not
necessarily good candidates to review new patches.
This patch allows get_maintainers to optionally restrict output to only
signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:.
Signed-off-by: is included because those are people who are responsible
for the code.
Acked-by: is questionable, but as signers that use this tag tend to be
active linux gatekeepers, false positives are tolerable.
Reviewed-by: is included because signers responsible for the code thought
that the review feedback for a changeset by that signer was valuable.
This patch has been modified from Florian's original submission to change
the supported signature types to the canonical forms and use slightly
different spacing. A couple of spacing issues were also corrected in the
original source. The command line argument was also renamed.

The patch below works fine (at least with Debian). It needs your first
patch that moves the definitions to mod_devicetable.h. Verified that
aliases for these modules are generated correctly:
drivers/media/radio/radio-sf16fmi.c
drivers/net/ne.c
drivers/net/3c515.c
drivers/net/smc-ultra.c
drivers/pcmcia/i82365.c
drivers/scsi/aha1542.c
drivers/scsi/aha152x.c
drivers/scsi/sym53c416.c
drivers/scsi/g_NCR5380.c
Tested with RTL8019AS (ne), AVA-1505AE (aha152x) and dtc436e (g_NCR5380)
cards - they now work automatically.
Generate pnp:d aliases for isapnp_device_tables. This allows udev to load
these modules automatically.

There's a button in gconfig to "Show all options", but I think
normally we are not interested in those configs which have no
prompt and thus can't be changed, so here I add a new button to
show hidden options which have prompts.

Usage:
Press <Z> to show all config symbols which have prompts.

I myself found this useful too. For example, I need to test
ftrace/tracing and want to be sure all the tracing features are
enabled, so I enter the "Tracers" menu, and press <Z> to
see if there is any config hidden.
I also noticed gconfig and xconfig have a button "Show all options",
but that's a bit too much, and I think normally what we are not
interested in those configs which have no prompt thus can't be
changed by users.
Exmaple:
--- Tracers
-*- Kernel Function Tracer
- - Kernel Function Graph Tracer
[*] Interrupts-off Latency Tracer
- - Preemption-off Latency Tracer
[*] Sysprof Tracer
Here you can see 2 tracers are not selectable, and then can find
out how to make them selectable.
