Subject: [PATCH v4 04/18] arm64: Add ESR_ELx_FSC_ADDRSZ_L() helper
Date: Tue, 20 Aug 2024 11:37:42 +0100	[thread overview]
Message-ID: <20240820103756.3545976-5-maz@kernel.org> (raw)
In-Reply-To: <20240820103756.3545976-1-maz@kernel.org>

Although we have helpers that encode the level of a given fault
type, the Address Size fault type is missing it.

While we're at it, fix the bracketting for ESR_ELx_FSC_ACCESS_L()
and ESR_ELx_FSC_PERM_L().
