Subject: [GIT PULL] arm64: fixes for -rc2

Hi Linus,

Please pull these arm64 fixes for -rc2. Details in the tag, but the main
thing here is to get us booting under qemu again after it turned out
that not all of the PMU registers are emulated there, causing us to
die early in boot.

Cheers,

Will

  arm64: mm: avoid calling apply_to_page_range on empty range (2016-01-26 15:56:44 +0000)

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

- Ensure we don't access PMU registers of the PMU is not implemented
  (fixes booting under QEMU)

- Fix BUG_ON triggered during module loading with DEBUG_SET_MODULE_RONX

- Ensure the kasan zero page is read-only

- Hide __efistub_ symbol aliases from kallsyms, since they otherwise
  confuse the backtrace code

- Ensure !PTE_WRITE kernel ptes are marked as read-only

- defconfig updates based on requests and patches on the list

- Other minor fixes (typos, build system)
