perf_events: Fix bogus AMD64 generic TLB events
commit ba0cef3d149ce4db293c572bf36ed352b11ce7b9 upstream.
PERF_COUNT_HW_CACHE_DTLB:READ:MISS had a bogus umask value of 0 which
counts nothing. Needed to be 0x7 (to count all possibilities).
PERF_COUNT_HW_CACHE_ITLB:READ:MISS had a bogus umask value of 0 which
counts nothing. Needed to be 0x3 (to count all possibilities).
