a58e76f254 [PATCH] Remove obsolete HAVE_ARCH_GET_SIGNAL_TO_DELIVER?
Now m68k no longer sets HAVE_ARCH_GET_SIGNAL_TO_DELIVER, can it be removed
completely? Or may ARM26 still need it? Note that its usage was removed from
kernel/signal.c about 2 months ago.

ce10d97905 [PATCH] ppc64: Fix PER_LINUX32 behaviour
This patch fixes some bugs in the ppc64 PER_LINUX32 implementation,
noted by Juergen Kreileder:

* uname(2) doesn't respect PER_LINUX32, it returns 'ppc64' instead of 'ppc'
* Child processes of a PER_LINUX32 process don't inherit PER_LINUX32

Along the way I took the opportunity to move things around so that
sys_ppc32.c only has 32-bit syscall emulation functions and to remove
the obsolete "fakeppc" command line option.

05062d96a2 [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.

07eee78ea8 [PATCH] AGP fix for Xen VMM
When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART.  This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.

Architecture-specific functions are also defined for allocating and freeing
the GATT.  Xen requires this to ensure that table really is contiguous from
the point of view of the GART.

These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.

c5c3a6d8fe [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.

Great!  FWIW I've briefly tested a modified version of usbatm using
the list head in struct urb instead of creating a wrapper struct, and I
haven't seen any failures yet.  So I tend to believe that your "should
be" actually means "is" :)

5f64f73957 [PATCH] ppc32/ppc64: cleanup /proc/device-tree
This cleans up the /proc/device-tree representation of the Open Firmware
device-tree on ppc and ppc64.  It does the following things:

 - Workaround an issue in some Apple device-trees where a property may
   exist with the same name as a child node of the parent.  We now
   simply "drop" the property instead of creating duplicate entries in
   /proc with random result...

 - Do not try to chop off the "@0" at the end of a node name whose unit
   address is 0.  This is not useful, inconsistent, and the code was
   buggy and didn't always work anyway.

 - Do not create symlinks for the short name and unit address parts of a
   node.  These were never really used, bloated the memory footprint of
   the device-tree with useless struct proc_dir_entry and their matching
   dentry and inode cache bloat.

This results in smaller code, smaller memory footprint, and a more
accurate view of the tree presented to userland.
