[GIT PULL] arm64: fixes for -rc5

[Will Deacon]

Hi Linus,

Here are some more arm64 fixes for 4.5. This has mostly come from Yang
Shi, who saw some issues under -rt that also affect mainline. The rest
of it is pretty small, but still worth having.

We've got an old issue outstanding with valid_user_regs which will
likely wait until 4.6 (since it would really benefit from some time in
-next) and another issue with kasan and idle which should be fixed next
week.

Apart from that, pretty quiet here (and still no sign of the THP issue
reported on s390...)

  arm64: mm: allow the kernel to handle alignment faults on user accesses (2016-02-19 12:20:37 +0000)

----------------------------------------------------------------
arm64 fixes:

- Allow EFI stub to use strnlen(), which is required by recent libfdt

- Avoid smp_processor_id() in preempt context during unwinding

- Avoid false Kasan warnings during unwinding

- Ensure early devices are picked up by the IOMMU DMA ops

- Avoid rebuilding the kernel for the 'install' target

- Run fixup handlers for alignment faults on userspace access
