UPSTREAM: x86/uaccess: force copy_*_user() to be inlined
As already done with __copy_*_user(), mark copy_*_user() as __always_inline.
Without this, the checks for things like __builtin_const_p() won't work
consistently in either hardened usercopy nor the recent adjustments for
detecting usercopy overflows at compile time.
The change in kernel text size is detectable, but very small:
