The primary dependency is that GHES uses the x86 NMI for hardware error notification and MCE for memory error handling. These patches remove that dependency. Other APEI features such as error reporting via external IRQ, error serialization, or error injection, do not require changes to use them on non-x86 architectures. The following patch set eliminates the APEI Kconfig x86 dependency by making these changes: - treat NMI notification as GHES architecture - HAVE_ACPI_APEI_NMI - group and wrap around #ifdef CONFIG_HAVE_ACPI_APEI_NMI code which is used only for NMI path - identify architectural boxes and abstract it accordingly (tlb flush and MCE) - rework ioremap for both IRQ and NMI context NMI code is kept in ghes.c file since NMI and IRQ context are tightly coupled. Note, these patches introduce no functional changes for x86. The NMI notification feature is hard selected for x86. Architectures that want to use this feature should also provide NMI code infrastructure. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT2BaPAAoJEKurIx+X31iBLGMP/0yyWOna4229p9CmuElSP3os Kb+9Thru+Wg4ihj43CYW0nznQnamCaqBa5NpDXZn0Ebtxc08SSGVzbf+z+vBMeD+ HW4093m4g8sGL7i4JdAol0MEPpKTQRdpj525N/h/xWVSDXQ0Bq3vQ7DS1/j1Bp4k Lq3G8dEk+4LjNPcQ5YBPl71zWJOC4iUctfh1OpFdfgA04804Vis3j8T6ljE7/72M 51xXK3af9ktIg6MU2HOwraUsSspVeJs/4lPu4fab4XI07BRDb4T7yx19a9VaBy67 m6TaTd3eC/Z0Uh+51grNuXSnWQK4fvahRZJEwiRdC0wL3w3mhdZkmqm0nBdBFyof 5b251+FOazOtZdMsWS/mMjQUjybQ+4k9zpnndIPw/5rqxJ8lgaP7o81e+hw1Xh1Q E0ZWUMXnAIkRmkyYLUv5aTICRYIZtAC/C1QrR5ZB/9Q+yvtxp13dbqGzWhcF7AIw UK/yb5T5ZAzvuJlmPG0ZiV75HH9bjX4OFV3AhXJIEG/iTOdVVpat8yICFrT33Xpc uAwRXQvz6mn2c2xpZcJqSJQlXKg2nbrfUmscU8P8Zu6mQpvBB/+2cDbW/5wfuKbE NpD0aB5PxhHY+nNvIfOsTUk72aZcZdUEQJt/792vhnMYb/IK1X/qa4zrVmOqlZKt mtXwUQWdj3kSG36mgssO =nYdd -----END PGP SIGNATURE----- Merge tag 'please-pull-apei' into x86/ras APEI is currently implemented so that it depends on x86 hardware.
