Subject[PATCH 0/2] perf tools: Fix symbol error on ARM64
Date
He Kuang has described this problem at [1] that, on ARM64, perf report
output wrong symbol for a shared object.

These two patches solve this problem. The key is patch 2/2: force
adjust symbol for shared object. However, after setting
dso->adjust_symbols, map__rip_2objdump() also need to be adjust, or
perf annotate reports incorrect result. Patch 1/1 prepare this change.
