[RFC PATCH 3/3] getcpu_cache: wire up x86 32/64 system call

2016-01-04 Thread Mathieu Desnoyers
Wire up the getcpu_cache system call on x86 32/64. Call the getcpu_cache_handle_notify_resume() function on return to userspace if TIF_NOTIFY_RESUME thread flag is set. This provides an ABI improving the speed of a getcpu operation on x86 by removing the need to perform a function call, "lsl"
