From f96935d3bc38a5f4b5188b6470a10e3fb8c3f0cc Mon Sep 17 00:00:00 2001 From: James Morse Date: Tue, 29 Jan 2019 18:49:01 +0000 Subject: firmware: arm_sdei: Add ACPI GHES registration helper APEI's Generic Hardware Error Source structures do not describe whether the SDEI event is shared or private, as this information is discoverable via the API. GHES needs to know whether an event is normal or critical to avoid sharing locks or fixmap entries, but GHES shouldn't have to know about the SDEI API. Add a helper to register the GHES using the appropriate normal or critical callback. Signed-off-by: James Morse Acked-by: Catalin Marinas Signed-off-by: Rafael J.
