From mboxrd@z Thu Jan 1 00:00:00 1970 From: mark.rutland@arm.com (Mark Rutland) Date: Thu, 31 May 2018 18:32:19 +0100 Subject: [PATCHv2 0/4] arm64: SMCCC conduit cleanup Message-ID: <20180531173223.9668-1-mark.rutland@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Currently, the cpu errata code goes digging into PSCI internals to discover the SMCCC conduit, using the (arguably misnamed) PSCI_CONDUIT_* definitions. This lack of abstraction is somewhat unfortunate. Further, the SDEI code has an almost identical set of CONDUIT_* definitions, and the duplication is rather unfortunate. Let's unify things behind a common set of SMCCC_CONDUIT_* definitions, and expose the SMCCCv1.1 conduit via a new helper that hides the PSCI driver internals. Since v1 [1]: * Rebase to the arm64 for-next/core branch, atop of SSBD patches * Fold in acks Mark.
