This patch fixes some bugs in the ppc64 PER_LINUX32 implementation,

* Child processes of a PER_LINUX32 process don't inherit PER_LINUX32

[PATCH] ia64: fix floating-point preemption problem
There've been reports of problems with CONFIG_PREEMPT=y and the high
floating point partition. This is caused by the possibility of preemption
and rescheduling on a different processor while saving or restioirng the
high partition.
The only places where the FPU state is touched are in ptrace, in
switch_to(), and where handling a floating-point exception. In switch_to()
preemption is off. So it's only in trap.c and ptrace.c that we need to
prevent preemption.
Here is a patch that adds commentary to make the conditions clear, and adds
appropriate preempt_{en,dis}able() calls to make it so. In trap.c I use
preempt_enable_no_resched(), as we're about to return to user space where
the preemption flag will be checked anyway.

[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).
As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices. This isn't always true. Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.
The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode. I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place. According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.
With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).
Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.
This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.

Architecture-specific functions are also defined for allocating and freeing

These extra interface functions are defined as 'no-ops' for all existing

[TG3] Fix link failure in 5701
On some 5701 devices with older bootcode, the LED configuration bits in

error in programming the PHY.
Thanks to Grant Grundler for debugging the problem.

| In May, 2004, tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting

getting dropped.

[PATCH] s390: uml ptrace fixes
To make UML build and run on s390, I needed to do these two little
changes:
1) UML includes some of the subarch's (s390) headers. I had to
change one of them with the following one-liner, to make this
compile. AFAICS, this change doesn't break compilation of s390
itself.
2) UML needs to intercept syscalls via ptrace to invalidate the syscall,
read syscall's parameters and write the result with the result of
UML's syscall processing. Also, UML needs to make sure, that the host
does no syscall restart processing. On i386 for example, this can be
done by writing -1 to orig_eax on the 2nd syscall interception
(orig_eax is the syscall number, which after the interception is used
as a "interrupt was a syscall" flag only.
Unfortunately, s390 holds syscall number and syscall result in gpr2 and
its "interrupt was a syscall" flag (trap) is unreachable via ptrace.
So I changed the host to set trap to -1, if the syscall number is changed
to an invalid value on the first syscall interception.

[PATCH] mpage_end_io_write() I/O error handling fix
When fsync() runs wait_on_page_writeback_range() it only inspects pages which
are actually under I/O (PAGECACHE_TAG_WRITEBACK). If a page completed I/O
prior to wait_on_page_writeback_range() looking at it, it is supposed to have
recorded its I/O error state in the address_space.
But mpage_mpage_end_io_write() forgot to set the address_space error flag in
this case.
