a3a6261a11 kbuild: fix genksyms Makefile
When enabling GENERATE_PARSER the genksyms Makefile
failed to create _shipped version of generated files.

Modifying keywords.gperf failed to cause a rebuild
of genksyms.
Fixed by specifying keywowrds .c as explicit prerequisite
of the lexer.

cc9eefdb9e kbuild: scripts/ver_linux : correct printing of binutils version
Currently scripts/ver_linux prints "Binutils" or other random
information for the version number in the "binutils" output line
on some distributions. This patch corrects that.

When I initially submitted a patch to correct that, I was not aware
that the output from "ld -v" could differ as much as it turned out
it can, so my original fix turned out to not cover all bases.
This patch works correctly with all the different "ld -v" output
that people posted in replys to my first patch, so it should be a
clear win over what we have currently.

9cc3ef3034 kbuild: ver_linux fix glibc version print
Fix ver_linux glibc version printing (for real this time)

Alexey Dobriyan reported that commit
4a645d5ea6
broke ver_linux when glibc has a 3 digit
version number, and proposed a patch.
Al Viro then suggested a simpler way to
solve the problem which I've then simply
put into patch form.

de47062a17 kbuild: improve scripts/gcc-version.sh output a bit when called without args
Currently, if you call scripts/gcc-version.sh without arguments it will
generate this output :

$ sh scripts/gcc-version.sh
scripts/gcc-version.sh: line 12: [: =: unary operator expected
scripts/gcc-version.sh: line 16: -E: command not found
scripts/gcc-version.sh: line 17: -E: command not found
0000

Not too pretty. I believe this is an improvement :

$ sh scripts/gcc-version.sh
Error: No compiler specified.
Usage:
        scripts/gcc-version.sh <gcc-command>

0bce67352b kbuild: script to check for undefined Kconfig symbols
To avoid having to look manually for used but undefined Kconfig variables,
I've written a script which tries do this efficiently, in case all other
attention fail.  It accounts for _MODULE suffix and for UML_ prefixes to
Kconfig variable, but otherwise looks for exact matches (i.e.  \<CONFIG_;
this is done to exclude macros like MMCONFIG_).

Undefined Kconfig variables should be not be removed without care, but for
instance arch/i386/boot/ uses a bunch of undefined Kconfig vars:

$ scripts/checkunknowndefines.sh arch/i386/boot/
arch/i386/boot/video.h uses undefined symbol VIDEO_400_HACK
arch/i386/boot/video-vga.c uses undefined symbol VIDEO_400_HACK
arch/i386/boot/video.c uses undefined symbol VIDEO_RETAIN
arch/i386/boot/video.h uses undefined symbol VIDEO_RETAIN
arch/i386/boot/video.h uses undefined symbol VIDEO_SVGA
arch/i386/boot/video.h uses undefined symbol VIDEO_VESA
arch/i386/boot/video-vesa.c uses undefined symbol VIDEO_VESA

It should also be mentioned in SubmittingPatches and SubmitChecklist.

aa1e5ef5c1 kbuild: check if we can link gettext not just compile
cygwin provides the header file but the lib file needs
to be added manually. A generic fix is to check if
we can compile and link a program that uses gettext()
and if it fails fall back to NO_NLS.

b63db45ca4 [POWERPC] Add legacy serial support for OPB with flattened device tree
Currently find_legacy_serial_ports() can find no serial ports on the
OPB with flattened device tree.  Thus no legacy boot console can be
initialized.  Just the early udbg console works, which is initialized
with udbg_init_44x_as1 on the UART's physical address specified in
kernel config.  This happens because we look for ns16750 serial
devices only and expect opb node to have a device type property.  This
patch makes it look for ns16550-compatible devices and use
of_device_is_compatible() for opb in case device type is not
specified.

1189be6508 [POWERPC] Use 1TB segments
This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).

We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.

We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments.  That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.

Parts of this patch were originally written by Ben Herrenschmidt.

6f53576316 [NET]: Fix NAPI completion handling in some drivers.
In order for the list handling in net_rx_action() to be
correct, drivers must follow certain rules as stated by
this comment in net_rx_action():

		/* Drivers must not modify the NAPI state if they
		 * consume the entire weight.  In such cases this code
		 * still "owns" the NAPI instance and therefore can
		 * move the instance around on the list at-will.
		 */

A few drivers do not do this because they mix the budget checks
with reading hardware state, resulting in crashes like the one
reported by takano@axe-inc.co.jp.

BNX2 and TG3 are taken care of here, SKY2 fix is from Stephen
Hemminger.

b08d6cb22c [TCP]: Limit processing lost_retrans loop to work-to-do cases

f785a8e28b [TCP]: Fix lost_retrans loop vs fastpath problems
Detection implemented with lost_retrans must work also when
fastpath is taken, yet most of the queue is skipped including
(very likely) those retransmitted skb's we're interested in.
This problem appeared when the hints got added, which removed
a need to always walk over the whole write queue head.
Therefore decicion for the lost_retrans worker loop entry must
be separated from the sacktag processing more than it was
necessary before.

It turns out to be problematic to optimize the worker loop
very heavily because ack_seqs of skb may have a number of
discontinuity points. Maybe similar approach as currently is
implemented could be attempted but that's becoming more and
more complex because the trend is towards less skb walking
in sacktag marker. Trying a simple work until all rexmitted
skbs heve been processed approach.

Maybe after(highest_sack_end_seq, tp->high_seq) checking is not
sufficiently accurate and causes entry too often in no-work-to-do
cases. Since that's not known, I've separated solution to that
from this patch.

Noticed because of report against a related problem from TAKANO
Ryousei <takano@axe-inc.co.jp>. He also provided a patch to
that part of the problem. This patch includes solution to it
(though this patch has to use somewhat different placement).
TAKANO's description and patch is available here:

  http://marc.info/?l=linux-netdev&m=119149311913288&w=2

...In short, TAKANO's problem is that end_seq the loop is using
not necessarily the largest SACK block's end_seq because the
current ACK may still have higher SACK blocks which are later
by the loop.

Both sacked_out and fackets_out are directly known from how
parameter. Since fackets_out is accurate, there's no need for
recounting (sacked_out was previously unnecessarily counted
in the loop anyway).
