Greetings,
another set of patches for s390. Patch #3 is the only one that
is not completely boring, it improves the quality of the idle
cpu accounting field in /proc/stat.

[-- Attachment #1: 002-appldata-mem-deadlock.diff --]
[-- Type: text/plain, Size: 4512 bytes --]

From: Gerald Schaefer <gerald.schaefer@de.ibm.com>

The appldata_ops callbacks are called with a spin_lock held. But the
appldata_mem callback then calls all_vm_events(), which calls
get_online_cpus(), which might sleep. This possible deadlock is fixed
by using a mutex instead of a spin_lock.

[-- Attachment #1: 003-idle-stat.diff --]
[-- Type: text/plain, Size: 3144 bytes --]

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

The cpu idle field in the output of /proc/stat is too small for cpus
that have been idle for more than a tick. Add the architecture hook
arch_idle_time that allows to add the not accounted idle time of a
sleeping cpu without waking the cpu.

The s390 implementation of arch_idle_time uses the already existing
s390_idle_data per_cpu variable to find the sleep time of a neighboring
idle cpu.

From: Heiko Carstens <heiko.carstens@de.ibm.com>

Always omit frame pointers on s390. They aren't too useful for the
kernel since we have already the kernel stack backchain which allows
us to walk the kernel stack.
So eleminate the extra code for frame pointers. Only allow the extra
code for the function tracer since the gcc compile options -pg and
-fomit-frame-pointer are incompatible.
