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

Pull ARM fixes from Russell King:

 - Fix clang-related relocation warning in futex code

 - Fix incorrect use of get_kernel_nofault()

 - Fix bad code generation in __get_user_check() when kasan is enabled

 - Ensure TLB function table is correctly aligned

 - Remove duplicated string function definitions in decompressor

 - Fix link-time orphan section warnings

 - Fix old-style function prototype for arch_init_kprobes()

 - Only warn about XIP address when not compile testing

 - Handle BE32 big endian for keystone2 remapping
