      ARM/audit: include audit header and fix audit arch · 5180bb39
      Eric Paris authored
      Both bugs being fixed were introduced in:
      29ef73b7
      
      Include linux/audit.h to fix below build errors:
      
        CC      arch/arm/kernel/ptrace.o
      arch/arm/kernel/ptrace.c: In function 'syscall_trace':

      Reported-by: default avatarPeter Ujfalusi <peter.ujfalusi@ti.com>
      (They both provided patches to fix it)
      
      This patch also (at the request of the list) fixes the fact that
      ARM has both LE and BE versions however the audit code was called as if
      it was always BE.  If audit userspace were to try to interpret the bits
      it got from a LE system it would obviously do so incorrectly.  Fix this
      by using the right arch flag on the right system.

      ARM: OMAP: fix voltage domain build errors with PM_OPP disabled · 3ddd4d0c
      Russell King authored
      The voltage domain code wants the voltage tables, which are in the
      opp*.c files.  These files aren't built when PM_OPP is disabled,
      causing the following build errors at link time:

      ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency' · e23e8c06
      Myron Stowe authored
      The patch series to re-factor PCI's 'latency timer' setup (re:
      http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
      remove the ARM specific definition of 'pcibios_max_latency' once such
      had been moved into the pci core resulting in ARM related compile
      errors -
        drivers/built-in.o:(.data+0x230): multiple definition of
        `pcibios_max_latency'
        arch/arm/common/built-in.o:(.data+0x40c): first defined here
        make[1]: *** [vmlinux.o] Error 1
      
      In the series, patch 2/16 (commit 168c8619) converted the ARM
      specific version of 'pcibios_set_master()' to a non-inlined version.
      This was done in preperation for hosting it up into PCI's core, which
      was done in patch 10/16 (commit 96c55900) of the series (and
      where the removal of ARM's 'pcibios_max_latency' was overlooked).

      ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised · 910ba598
      Santosh Shilimkar authored
      Current ARM local timer code registers CPUFREQ notifiers even in case
      the twd_timer_setup() isn't called. That seems to be wrong and
      would eventually lead to kernel crash on the CPU frequency transitions
      on the SOCs where the local timer doesn't exist or broken because of
      hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt).
      
      The issue was observed with v3.3-rc3 and building an OMAP2+ kernel
      on OMAP3 SOC which doesn't have TWD.
      
      Below is the dump for reference :
