Marco Elver 1c1e7514cf objtool, kcsan: Add volatile read/write instrumentation to whitelist ...

[ Upstream commit 63646fcba5 ]

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: 75d75b7a4d ("kcsan: Support distinguishing volatile accesses")
