[PATCH v3 0/6] perf kvm: A small update in the default arch event

[Namhyung Kim <namhyung@kernel.org>]

Hello,

Ian said there's an issue in the perf kvm record command line option parsing.
This is my attempt to address the issue, simplify the code and fix memory leaks.

v3 changes)
 * remove unnecessary error check  (Sashiko)
 * update test code after rebase
 
v2 changes)
 * handle kvm top subcommand  (Sashiko)
 * handle other arch/condition for the default events  (Sashiko)
 * add <stdlib.h> for musl compatibility  (Sashiko)
 * fix some memory leaks

Thanks,
Namhyung
