Subject: [PATCH 06/27] arm64: Add debug registers affected by HDFGxTR_EL2
Date: Wed, 12 Jul 2023 15:57:49 +0100	[thread overview]
Message-ID: <20230712145810.3864793-7-maz@kernel.org> (raw)
In-Reply-To: <20230712145810.3864793-1-maz@kernel.org>

The HDFGxTR_EL2 registers trap a (huge) set of debug and trace
related registers. Add their encodings (and only that, because
we really don't care about what these registers actually do at
this stage).
