From b972d2eaf0c7021579755eec6b2b79e0f5bc7930 Mon Sep 17 00:00:00 2001 From: James Morse Date: Tue, 29 Jan 2019 18:48:57 +0000 Subject: ACPI / APEI: Use separate fixmap pages for arm64 NMI-like notifications Now that ghes notification helpers provide the fixmap slots and take the lock themselves, multiple NMI-like notifications can be used on arm64. These should be named after their notification method as they can't all be called 'NMI'. x86's NOTIFY_NMI already is, change the SEA fixmap entry to be called FIX_APEI_GHES_SEA. Future patches can add support for FIX_APEI_GHES_SEI and FIX_APEI_GHES_SDEI_{NORMAL,CRITICAL}. Because all of ghes.c builds on both architectures, provide a constant for each fixmap entry that the architecture will never use. Signed-off-by: James Morse Signed-off-by: Rafael J.
