ARM: make get_current() and __my_cpu_offset() __always_inline
The get_current() and __my_cpu_offset() accessors evaluate to only a single instruction emitted inline, but due to the size of the asm string that is created for SMP+v6 configurations, the compiler assumes otherwise, and may emit the functions out of line instead. So use __always_inline to avoid this. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com>
