  arm64: Improve error reporting on set_pte_at() checks (2015-12-11 15:44:24 +0000)

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

- Update the linker script to use L1_CACHE_BYTES instead of hard-coded
  64. We recently changed L1_CACHE_BYTES to 128

- Improve race condition reporting on set_pte_at() and change the BUG to
  WARN_ONCE. With hardware update of the accessed/dirty state, we need
  to ensure that set_pte_at() does not inadvertently override hardware
  updated state. The patch also makes the checks ignore !pte_valid() new
  entries

----------------------------------------------------------------
Ard Biesheuvel (1):
      arm64: update linker script to increased L1_CACHE_BYTES value
