[PATCH 11/21] arm64: percpu: Annotate __kern_my_cpu_offset() as '__always_inline'

[Will Deacon]

Allow the use of per-cpu variables from noinstr functions by marking
__kern_my_cpu_offset() as '__always_inline'. This will later be relied
upon to detect stack overflow of the overflow stack from noinstr C code.
