Subject: [PATCH 0/3] ARM: trivial assembly fixes to enable LLVM as

During the last few days I tried compiling the kernel for ARM32 with
LLVMs integrated assembler. The elephant in the room is definitely the
unified syntax which is required by the LLVM assembler. I converted most
mnemonics using a regex, but it is not perfect and needs some manual fixes.
I am not sure if this is the right approach, feedback welcome. I plan to
send fixes in groups in the next few weeks, if that effort is welcome.

There are a couple of other issues besides unified syntax, e.g. lack of
feature argument parsing (e.g. armv7-a+sec).

This patchset is a starting point to enable LLVM integrated assembler and
contains some trivial changes. With this patchset the LLVM integrated
assembler can be used to assemble almost all C files.

Stefan Agner (3):
  ARM: fix argument count to match macro definition
  ARM: uaccess: use unified assembler language syntax
  ARM: spinlock: use unified assembler language syntax
