[GIT PULL] arm64: fixes for -rc2

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc2. Most of these are CC'd for
stable, but there are a few fixing issues introduced during the recent
merge window too. There's also a fix for the xgene PMU driver, but it
seemed daft to send as a separate pull request, so I've included it
here with the rest of the fixes. More details in the tag.

Thanks,

Will

  arm64: remove pr_cont abuse from mem_init (2016-10-20 15:27:56 +0100)

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

- Fix ACPI boot due to recent broken NUMA changes
- Fix remote enabling of CPU features requiring PSTATE bit manipulation
- Add address range check when emulating user cache maintenance
- Fix LL/SC loops that allow compiler to introduce memory accesses
- Fix recently added write_sysreg_s macro
- Ensure MDCR_EL2 is initialised on qemu targets without a PMU
- Avoid kaslr breakage due to MODVERSIONs and DYNAMIC_FTRACE
- Correctly drive recent ld when building relocatable Image
- Remove junk IS_ERR check from xgene PMU driver added during merge window
- pr_cont fixes after core changes in the merge window
