Used the following script to copy the files:
cd include
set -e
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
if [ -f asm-sparc/$FILE ]; then
echo $FILE exist in asm-sparc
else
git mv asm-sparc64/$FILE asm-sparc/$FILE
printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
git add asm-sparc64/$FILE
fi
done

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.

Copy content of sparc64 file to sparc file.
There is only minimal possibilities for further unification.

Bring the commit e55c57e0b51c68d78845549505057169c6c3cba6
("[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.

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.

There were only a few trivial changes and a few additions
in the sparc64 variant of this file.
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.

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.

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.

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 ...

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>.

As part of a heuristic to identify modem devices, 8250_pnp.c
checks to see whether a device can be configured at any of the
legacy COM port addresses.
This patch moves the code that traverses the PNP "possible resource
options" from 8250_pnp.c to the PNP subsystem. This encapsulation
is important because a future patch will change the implementation
of those resource options.

PNP used to have a fixed-size pnp_resource_table for tracking the
resources used by a device. This table often overflowed, so we've
had to increase the table size, which wastes memory because most
devices have very few resources.
This patch replaces the table with a linked list of resources where
the entries are allocated on demand.
This removes messages like these:
pnpacpi: exceeded the max number of IO resources
00:01: too many I/O port resources
References:
http://bugzilla.kernel.org/show_bug.cgi?id=9535
http://bugzilla.kernel.org/show_bug.cgi?id=9740
http://lkml.org/lkml/2007/11/30/110
This patch also changes the way PNP uses the IORESOURCE_UNSET,
IORESOURCE_AUTO, and IORESOURCE_DISABLED flags.
Prior to this patch, the pnp_resource_table entries used the flags
like this:
IORESOURCE_UNSET
This table entry is unused and available for use. When this flag
is set, we shouldn't look at anything else in the resource structure.
This flag is set when a resource table entry is initialized.
IORESOURCE_AUTO
This resource was assigned automatically by pnp_assign_{io,mem,etc}().
This flag is set when a resource table entry is initialized and
cleared whenever we discover a resource setting by reading an ISAPNP
config register, parsing a PNPBIOS resource data stream, parsing an
ACPI _CRS list, or interpreting a sysfs "set" command.
Resources marked IORESOURCE_AUTO are reinitialized and marked as
IORESOURCE_UNSET by pnp_clean_resource_table() in these cases:
- before we attempt to assign resources automatically,
- if we fail to assign resources automatically,
- after disabling a device
IORESOURCE_DISABLED
Set by pnp_assign_{io,mem,etc}() when automatic assignment fails.
Also set by PNPBIOS and PNPACPI for:
- invalid IRQs or GSI registration failures
- invalid DMA channels
- I/O ports above 0x10000
- mem ranges with negative length
After this patch, there is no pnp_resource_table, and the resource list
entries use the flags like this:
IORESOURCE_UNSET
This flag is no longer used in PNP. Instead of keeping
IORESOURCE_UNSET entries in the resource list, we remove
entries from the list and free them.
IORESOURCE_AUTO
No change in meaning: it still means the resource was assigned
automatically by pnp_assign_{port,mem,etc}(), but these functions
now set the bit explicitly.
We still "clean" a device's resource list in the same places,
but rather than reinitializing IORESOURCE_AUTO entries, we
just remove them from the list.
Note that IORESOURCE_AUTO entries are always at the end of the
list, so removing them doesn't reorder other list entries.
This is because non-IORESOURCE_AUTO entries are added by the
ISAPNP, PNPBIOS, or PNPACPI "get resources" methods and by the
sysfs "set" command. In each of these cases, we completely free
the resource list first.
IORESOURCE_DISABLED
In addition to the cases where we used to set this flag, ISAPNP now
adds an IORESOURCE_DISABLED resource when it reads a configuration
register with a "disabled" value.
