[ Upstream commit 63646fcba5bb4b59a19031c21913f94e46a3d0d4 ]
Adds KCSAN's volatile instrumentation to objtool's uaccess whitelist.
Recent kernel change have shown that this was missing from the uaccess
whitelist (since the first upstreamed version of KCSAN):
mm/gup.o: warning: objtool: fault_in_readable+0x101: call to __tsan_volatile_write1() with UACCESS enabled
Fixes: 75d75b7a4d54 ("kcsan: Support distinguishing volatile accesses")
