x86/ptrace: Always inline trivial accessors

Browse source

[ Upstream commit 1fe4002cf7 ]

A KASAN build bloats these single load/store helpers such that
it fails to inline them:

  vmlinux.o: error: objtool: irqentry_exit+0x5e8: call to instruction_pointer_set() with UACCESS enabled

Make sure the compiler isn't allowed to do stupid.
