Subject: [PATCH 0/2] arm64/signal: Fix handling of TPIDR2
Date: Wed, 21 Jun 2023 22:00:49 +0100	[thread overview]
Message-ID: <20230621-arm64-fix-tpidr2-signal-restore-v1-0-b6d9e584d2ee@kernel.org> (raw)

The restoring of TPIDR2 signal context has been broken since it was
merged, fix this and add a test case covering it.  This is a result of
TPIDR2 context management following a different flow to any of the other
state that we provide and the fact that we don't expose TPIDR (which
follows the same pattern) to signals.
