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.
