  arm64: Relax ARM_SMCCC_ARCH_WORKAROUND_1 discovery (2018-03-09 17:52:07 +0000)

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

- The SMCCC firmware interface for the spectre variant 2 mitigation has
  been updated to allow the discovery of whether the CPU needs the
  workaround. This pull request relaxes the kernel check on the return
  value from firmware.

- Fix the commit allowing changing from global to non-global page table
  entries which inadvertently disallowed other safe attribute changes.

- Fix sleeping in atomic during the arm_perf_teardown_cpu() code.
