Subject: [PATCH] RISC-V: Ignore Zicfiss and Zicfilp for now
Date: Wed, 11 Mar 2026 10:02:33 +0000 [thread overview]
Message-ID: <20260311100233.384711-1-ben.dooks@codethink.co.uk> (raw)
These two are part of the CFI[1] and do not seem to need any
sort of special handling as yet. Just add these to list of
known extensions to stop annoying warnings from current
Linux kernel builds.
