b76e59d1fb powerpc/kprobes: Some minor fixes
* Mark __flush_icache_range as a function that can't be probed since its
  used by the kprobe code.

* Fix an issue with single stepping and async exceptions.  We need to
  ensure that we dont get an async exception (external, decrementer, etc)
  while we are attempting to single step the probe point.

  Added a check to ensure we only handle a single step if its really
  intended for the instruction in question.

aba11fc50c powerpc/e500mc: flush L2 on NAP for e500mc
If we have an L2CSR register (e500mc) we need to flush the L2 before going
to nap.  We use the HW flush mechanism provided in that register.

The code reuses the CPU_FTR_604_PERF_MON bit as it is no longer used by
any code in the kernel.  Additionally we didn't reuse the exist L2CR
feature bit as this is intended for the 7xxx L2CR register and L2CSR
is part of the new Freescale "Book-E" registers.

The esp driver currently does hand rolled reference counting of its
target.  It's much easier to do what it needs to do if it's plugged into
the mid-layer callbacks (target_alloc and target_destroy) which were
designed for this case, so do it this way and get rid of the internal
target reference count.

The usb_cache_mutex was not correctly released

didn't release the mutex under certain conditions
when the register access failed. Obviously such
failure would lead to deadlocks.

In addition under similar circumstances when the
bbp register couldn't be read the value must be
set to 0xff to indicate that the value is wrong.
This too didn't happen under all circumstances.

eadc49b1a8 [SCSI] esp: Fix OOPS in esp_reset_cleanup().
OOPS reported by Friedrich Oslage <bluebird@porno-bullen.de>

The problem here is that tp->starget is set every time a lun
is allocated for a particular target so we can catch the
sdev_target parent value.

The reset handler uses the NULL'ness of this value to determine
which targets are active.

But esp_slave_destroy() does not NULL out this value when appropriate.

So for every target that doesn't respond, the SCSI bus scan causes
a stale pointer to be left here, with ensuing crashes like you're
seeing.

7af192c954 x86: Add structs and functions for paravirt clocksource
This patch adds structs for the paravirt clocksource ABI
used by both xen and kvm (pvclock-abi.h).

It also adds some helper functions to read system time and
wall clock time from a paravirtual clocksource (pvclock.[ch]).
They are based on the xen code.  They are enabled using
CONFIG_PARAVIRT_CLOCK.

Subsequent patches of this series will put the code in use.

5af4e7a0be [GFS2] fix gfs2 block allocation (cleaned up)
This patch fixes bz 450641.

This patch changes the computation for zero_metapath_length(), which it
renames to metapath_branch_start(). When you are extending the metadata
tree, The indirect blocks that point to the new data block must either
diverge from the existing tree either at the inode, or at the first
indirect block. They can diverge at the first indirect block because the
inode has room for 483 pointers while the indirect blocks have room for
509 pointers, so when the tree is grown, there is some free space in the
first indirect block. What metapath_branch_start() now computes is the
height where the first indirect block for the new data block is located.
It can either be 1 (if the indirect block diverges from the inode) or 2
(if it diverges from the first indirect block).

e2569b7e57 [IA64] Eliminate NULL test after alloc_bootmem in iosapic_alloc_rte()
As noted by Akinobu Mita alloc_bootmem and related functions never return
NULL and always return a zeroed region of memory.  Thus a NULL test or
memset after calls to these functions is unnecessary.

8097110d17 [IA64] Handle count==0 in sn2_ptc_proc_write()
The fix applied in e0c6d97c65
"security hole in sn2_ptc_proc_write" didn't take into account
the case where count==0 (which results in a buffer underrun
when adding the trailing '\0').  Thanks to Andi Kleen for
pointing this out.

2826f8c0f4 [IA64] Fix boot failure on ia64/sn2
Call check_sal_cache_flush() after platform_setup() as
check_sal_cache_flush() now relies on being able to call platform
vector code.

Problem was introduced by: 3463a93def
"Update check_sal_cache_flush to use platform_send_ipi()"
