Subject: [PATCH 033/201] perf tools: Move ALLOC_LIST into a function
mainline inclusion
from mainline-v5.5-rc1
commit a26e47162d7670ddea4f67978ecf848dc23ef671
category: cleanup
bugzilla: https://gitee.com/openeuler/kernel/issues/I8C0CX
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a26e47162d7670ddea4f67978ecf848dc23ef671
------------------------------------------------------------------------
Having a YYABORT in a macro makes it hard to free memory for components
of a rule. Separate the logic out.
