[PATCH 0/3] perf tools: Tidy up symbol end fixup (v3)

[Namhyung Kim]

Hello,

This work is a follow-up of Ian's previous one at
  https://lore.kernel.org/all/20220412154817.2728324-1-irogers@xxxxxxxxxx/

Fixing up more symbol ends as introduced in:
  https://lore.kernel.org/lkml/20220317135536.805-1-mpetlan@xxxxxxxxxx/

it 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 fixup logic so that special kernel cases aren't
applied in the common case.

v3 changes)
 * rename is_kernel to is_kallsyms
 * move the logic to generic function
 * remove arch-specific functions

Thanks,
Namhyung

  perf symbol: Pass is_kallsyms to symbols__fixup_end()
  perf symbol: Update symbols__fixup_end()
  perf symbol: Remove arch__symbols__fixup_end()
