#     
#     Pull arm64 fixes from Will Deacon:
#      "A pair of arm64 fixes for -rc3. The straightforward one is a fix to
#       our firmware calling stub, which accidentally started corrupting the
#       link register on machines with SVE. Since these machines don't really
#       exist yet, it wasn't spotted in -next.
#     
#       The other fix is a revert-and-a-bit of a patch originally intended to
#       allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A
#       side-effect of this change was that our pXd_set_huge() implementations
#       could be replaced with generic dummy functions depending on the levels
#       of page-table being used, which in turn broke the boot if we fail to
#       create the linear mapping as a result of using these functions to
#       operate on the pgd. Huge thanks to Michael Ellerman for modifying the
#       revert so as not to regress PPC 8xx in terms of functionality.
#     
#       Anyway, that's the background and it's also available in the commit
#       message along with Link tags pointing at all of the fun.
#     
#       Summary:
#     
#        - Fix hang when issuing SMC on SVE-capable system due to
#          clobbered LR
#     
#        - Fix boot failure due to missing block mappings with folded
#          page-table"
