Re: [PATCH 4.19 35/47] x86/irq: Seperate unused system vectors from spurious entry again

[Guilherme G. Piccoli]

Hi Greg / Thomas and all involved here. First, apologies for
necro-bumping this thread, but I'm working a backport of this patch to
kernel 4.15 (Ubuntu) and then I noticed we have it on stable, but only
in 4.19+.

Since the fixes tag presents an old commit (since ~3.19), I'm curious if
we have a special reason to not have it on long-term stables, like 4.9
or 4.14. It's a subtle portion of arch code, so I'm afraid I didn't see
something that prevents its backport for previous versions.

Thanks in advance,


Guilherme
