Pull perf tools fixes from Namhyung Kim:
"Fix performance issue for v6.10
These address the performance issues reported by Matt, Namhyung and
Linus. Recently perf changed the processing of the comm string and DSO
using sorted arrays but this caused it to sort the array whenever
adding a new entry.
This caused a performance issue and the fix is to enhance the sorting
by finding the insertion point in the sorted array and to shift
righthand side using memmove()"
