Pull timer fixes from Thomas Gleixner:
 "Two fixes in the timer area:
   - a long-standing lock inversion due to a printk
   - suspend-related hrtimer corruption in sched_clock"

* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  timer: Fix lock inversion between hrtimer_bases.lock and scheduler locks
  sched_clock: Avoid corrupting hrtimer tree during suspend

Pull ARM fixes from Russell King:
 "A few fixes for ARM.  Some of these are correctness issues:
   - TLBs must be flushed after the old mappings are removed by the DMA
     mapping code, but before the new mappings are established.
   - An off-by-one entry error in the Keystone LPAE setup code.

  Fixes include:
   - ensuring that the identity mapping for LPAE does not remove the
     kernel image from the identity map.
   - preventing userspace from trapping into kgdb.
   - fixing a preemption issue in the Intel iwmmxt code.
   - fixing a build error with nommu.

  Other changes include:
   - Adding a note about which areas of memory are expected to be
     accessible while the identity mapping tables are in place"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 8124/1: don't enter kgdb when userspace executes a kgdb break instruction
  ARM: idmap: add identity mapping usage note
  ARM: 8115/1: LPAE: reduce damage caused by idmap to virtual memory layout
  ARM: fix alignment of keystone page table fixup
  ARM: 8112/1: only select ARM_PATCH_PHYS_VIRT if MMU is enabled
  ARM: 8100/1: Fix preemption disable in iwmmxt_task_enable()
  ARM: DMA: ensure that old section mappings are flushed from the TLB

The kgdb breakpoint hooks (kgdb_brk_fn and kgdb_compiled_brk_fn)
should only be entered when a kgdb break instruction is executed
from the kernel. Otherwise, if kgdb is enabled, a userspace program
can cause the kernel to drop into the debugger by executing either
KGDB_BREAKINST or KGDB_COMPILED_BREAK.

Add a note about the usage of the identity mapping; we do not support
accesses outside of the identity map region and kernel image while a
CPU is using the identity map.  This is because the identity mapping
may overwrite vmalloc space, IO mappings, the vectors pages, etc.
