[PATCH v2 0/4] Tidy up symbol end fixup

From: Ian Rogers
Date: Tue Apr 12 2022 - 11:48:32 EST


Fixing up more symbol ends as introduced in:
https://lore.kernel.org/lkml/20220317135536.805-1-mpetlan@xxxxxxxxxx/
caused perf annotate to run into memory limits - every symbol holds
all the disassembled code in the annotation, and so making symbols
ends further away dramatically increased memory usage (40MB to
>1GB). Modify the symbol end logic so that special kernel cases aren't
applied in the common case.

v2. Drops a merged patch. Fixes a build issue with libbfd enabled.

Ian Rogers (4):
perf symbols: Always do architecture specific fixups
perf symbols: Add is_kernel argument to fixup end
perf symbol: By default only fix zero length symbols
perf symbols: More specific architecture end fixing
