Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM development updates from Russell King:

 - Make it clear __swp_entry_to_pte() uses PTE_TYPE_FAULT

 - Updates for setting vmalloc size via command line to resolve an issue
   with the 8MiB hole not properly being accounted for, and clean up the
   code.

 - ftrace support for module PLTs

 - Spelling fixes

 - kbuild updates for removing generated files and pattern rules for
   generating files

 - Clang/llvm updates

 - Change the way the kernel is mapped, placing it in vmalloc space
   instead.

 - Remove arm_pm_restart from arm and aarch64.
