[PATCH 0/2] Fix atomic operations so that atomic64_test passes on ARM

A recently introduced Kernel feature is the atomic64_test on boot.
ARM fails these tests because the compiler is not correctly informed about
updates occuring to memory and is at liberty to constant-fold atomic64_t
variables.
This patch series adds the correct memory constraints to the atomic operations
on ARM and also enables all of the atomic64 tests in atomic64_test.c.
Will Deacon (2):
ARM: atomic ops: add memory constraints to inline asm
ARM: atomic64_test: add ARM as supported architecture
