Subject: [PATCH v2 0/6] ARM: clang support

This patchset fixes some remaining issues when building the ARM
architecture using LLVM/clang.  The patchset requires the following
kbuild change:
https://lkml.org/lkml/2018/3/19/1756

With that patch and this patchset applied and I can successfully
build (and boot) the multi_v7_defconfig with 4.16-rc5 using clang
5.0.1 and 6.0.0.

This version also adds a patch to mitigate a often printed warning
about duplicate 'const' declaration specifier when using get_user().

Stefan Agner (6):
  bus: arm-cci: use asm unreachable
  efi/libstub/arm: add support for building with clang
  ARM: trusted_foundations: do not use naked function
  ARM: drop no-thumb-interwork in EABI mode
  ARM: add support for building ARM kernel with clang
  ARM: uaccess: remove const to avoid duplicate specifier
