f5e706ad88 sparc: join the remaining header files
With this commit all sparc64 header files are moved to asm-sparc.
The remaining files (71 files) were too different to be trivially
merged so divide them up in a _32.h and a _64.h file which
are both included from the file with no bit size.

The following script were used:
cd include
FILES=`wc -l asm-sparc64/*h | grep -v '^     1' | cut -b 20-`

for FILE in ${FILES}; do
  echo $FILE:
  BASE=`echo $FILE | cut -d '.' -f 1`
  FN32=${BASE}_32.h
  FN64=${BASE}_64.h
  GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H
  git mv asm-sparc/$FILE asm-sparc/$FN32
  git mv asm-sparc64/$FILE asm-sparc/$FN64
  echo git mv done
  printf "#ifndef %s\n" $GUARD                             >   asm-sparc/$FILE
  printf "#define %s\n" $GUARD                             >>  asm-sparc/$FILE
  printf "#if defined(__sparc__) && defined(__arch64__)\n" >>  asm-sparc/$FILE
  printf "#include <asm-sparc/%s>\n" $FN64                 >>  asm-sparc/$FILE
  printf "#else\n"                                         >>  asm-sparc/$FILE
  printf "#include <asm-sparc/%s>\n" $FN32                 >>  asm-sparc/$FILE
  printf "#endif\n"                                        >>  asm-sparc/$FILE
  printf "#endif\n"                                        >>  asm-sparc/$FILE
  git add asm-sparc/$FILE
  echo new file done
  printf "#include <asm-sparc/%s>\n" $FILE                 >  asm-sparc64/$FILE
  git add asm-sparc64/$FILE
  echo sparc64 file done
done

The guard contains three '_' to avoid conflict with existing guards.
In additing the two Kbuild files are emptied to avoid breaking
headers_* targets.
We will reintroduce the exported header files when the necessary
kbuild changes are merged.

5e3609f60c sparc: merge header files with trivial differences
A manual inspection revealed that the following headerfiles
contained only trivial differences:
hw_irq.h idprom.h kmap_types.h kvm.h spinlock_types.h sunbpp.h unaligned.h

The only noteworthy change are that sparc64 had a volatile
qualifer that sparc missed in spinlock_types.h.

In addition a few comments were updated.

075ae52532 sparc: when header files are equal use asm-sparc version
Used the following script to find equal header files:
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
	cmp -s asm-sparc/$FILE asm-sparc64/$FILE;
	if [ $? = 0 ]; then
		printf "#include <asm-sparc/%s>\n" $FILE > asm-sparc64/$FILE
	fi
done

A few of the equal files are a simple include from
asm-generic, but by including the file from asm-sparc
we know they are equal for sparc and sparc64.

b1a8bf92a0 sparc: export openprom.h to userspace
sparc64 exports openprom.h to userspace so let sparc follow
the example.
As openprom.h pulled in another not-for-export vaddrs.h header
file it required a few changes to fix the build.

The definition af VMALLOC_* were moved to pgtable as this is
where sparc64 has them.

Bring the commit e55c57e0b5
("[SPARC64]: Report any user access faults in termios accessors")
over to sparc when unifying the two files.
The diff was manually inspected to contain no
other relevant changes.

This unification therefore changes functionality of sparc.

943d0e8613 sparc: Merge asm-sparc{,64}/termbits.h
The type of tcflag_t differs from 32 and 64 bit.
For 32 bit it is long
For 64 bit it is int

Altough these have same size then I was not sure that
it was OK to change the 64 bit version to long as this
is part of the ABI so it was made conditional.

This patch copies the sparc64 specific bits to the sparc version
of fbio.h so they are equal. A later patch will merge the two.

09d3e1baa1 sparc: copy exported sparc64 specific header files to asm-sparc
Copy was done using the following simple script:

set -e
SPARC64="h display7seg.h envctrl.h psrcompat.h pstate.h uctx.h utrap.h watchdog.h"
for FILE in ${SPARC64}; do
	if [ -f asm-sparc/$FILE ]; then
		echo $FILE exist in asm-sparc
	fi
	cat asm-sparc64/$FILE > asm-sparc/$FILE
	printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
done

The name of the copied files are added to asm-sparc/Kbuild
to keep "make headers_check" functional.

f470021adb ptrace children revamp
ptrace no longer fiddles with the children/sibling links, and the
old ptrace_children list is gone.  Now ptrace, whether of one's own
children or another's via PTRACE_ATTACH, just uses the new ptraced
list instead.

There should be no user-visible difference that matters.  The only
change is the order in which do_wait() sees multiple stopped
children and stopped ptrace attachees.  Since wait_task_stopped()
was changed earlier so it no longer reorders the children list, we
already know this won't cause any new problems.

1f32ca31e7 PNP: convert resource options to single linked list
ISAPNP, PNPBIOS, and ACPI describe the "possible resource settings" of
a device, i.e., the possibilities an OS bus driver has when it assigns
I/O port, MMIO, and other resources to the device.

PNP used to maintain this "possible resource setting" information in
one independent option structure and a list of dependent option
structures for each device.  Each of these option structures had lists
of I/O, memory, IRQ, and DMA resources, for example:

  dev
    independent options
      ind-io0  -> ind-io1  ...
      ind-mem0 -> ind-mem1 ...
      ...
    dependent option set 0
      dep0-io0  -> dep0-io1  ...
      dep0-mem0 -> dep0-mem1 ...
      ...
    dependent option set 1
      dep1-io0  -> dep1-io1  ...
      dep1-mem0 -> dep1-mem1 ...
      ...
    ...

This data structure was designed for ISAPNP, where the OS configures
device resource settings by writing directly to configuration
registers.  The OS can write the registers in arbitrary order much
like it writes PCI BARs.

However, for PNPBIOS and ACPI devices, the OS uses firmware interfaces
that perform device configuration, and it is important to pass the
desired settings to those interfaces in the correct order.  The OS
learns the correct order by using firmware interfaces that return the
"current resource settings" and "possible resource settings," but the
option structures above doesn't store the ordering information.

This patch replaces the independent and dependent lists with a single
list of options.  For example, a device might have possible resource
settings like this:

  dev
    options
      ind-io0 -> dep0-io0 -> dep1->io0 -> ind-io1 ...

All the possible settings are in the same list, in the order they
come from the firmware "possible resource settings" list.  Each entry
is tagged with an independent/dependent flag.  Dependent entries also
have a "set number" and an optional priority value.  All dependent
entries must be assigned from the same set.  For example, the OS can
use all the entries from dependent set 0, or all the entries from
dependent set 1, but it cannot mix entries from set 0 with entries
from set 1.

Prior to this patch PNP didn't keep track of the order of this list,
and it assigned all independent options first, then all dependent
ones.  Using the example above, that resulted in a "desired
configuration" list like this:

  ind->io0 -> ind->io1 -> depN-io0 ...

instead of the list the firmware expects, which looks like this:

  ind->io0 -> depN-io0 -> ind-io1 ...

d5ebde6ef5 PNP: support optional IRQ resources
This patch adds an IORESOURCE_IRQ_OPTIONAL flag for use when
assigning resources to a device.  If the flag is set and we are
unable to assign an IRQ to the device, we can leave the IRQ
disabled but allow the overall resource allocation to succeed.

Some devices request an IRQ, but can run without an IRQ
(possibly with degraded performance).  This flag lets us run
the device without the IRQ instead of just leaving the
device disabled.

This is a reimplementation of this previous change by Rene
Herman <rene.herman@gmail.com>:
    http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3b73a223661ed137c5d3d2635f954382e94f5a43

I reimplemented this for two reasons:
    - to prepare for converting all resource options into a single linked
      list, as opposed to the per-resource-type lists we have now, and
    - to preserve the order and number of resource options.

In PNPBIOS and ACPI, we configure a device by giving firmware a
list of resource assignments.  It is important that this list
has exactly the same number of resources, in the same order,
as the "template" list we got from the firmware in the first
place.

The problem of a sound card MPU401 being left disabled for want of
an IRQ was reported by Uwe Bugla <uwe.bugla@gmx.de>.

a1802c4295 PNP: make resource option structures private to PNP subsystem
Nothing outside the PNP subsystem should need access to a
device's resource options, so this patch moves the option
structure declarations to a private header file.
