But they sound like they're fixing the same thing:

"vmlinux no longer boots with CONFIG_PVH if CONFIG_KASAN_GENERIC is set."

and this one's commit message:

"This particular one (still) generated the inline implementation as expected
(at least in these compiler versions)"

sounds like it is referring to the previous patch. Or I don't know what you
mean with "these compiler versions"?

Bottom line: if someone needs to apply both to fix unbootable PVH VMs due to
mis-inlining of the compiler, then someone can simply apply one and be done
with it.

Thx.
