treewide: Add SPDX license identifier - Makefile/Kconfig Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2019-05-19 13:07:45 +01:00
RAS: Build debugfs.o only when enabled in Kconfig In addition, the 0day bot reported this build error: >> drivers/ras/debugfs.c:10:5: error: redefinition of 'ras_userspace_consumers' int ras_userspace_consumers(void) ^~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/ras/debugfs.c:3:0: include/linux/ras.h:14:19: note: previous definition of 'ras_userspace_consumers' was here static inline int ras_userspace_consumers(void) { return 0; } ^~~~~~~~~~~~~~~~~~~~~~~ for a riscv-specific .config where CONFIG_DEBUG_FS is not set. Fix all that by making debugfs.o depend on that define.

RAS: Add a Corrected Errors Collector Introduce a simple data structure for collecting correctable errors along with accessors. More detailed description in the code itself. The error decoding is done with the decoding chain now and mce_first_notifier() gets to see the error first and the CEC decides whether to log it and then the rest of the chain doesn't hear about it - basically the main reason for the CE collector - or to continue running the notifiers. When the CEC hits the action threshold, it will try to soft-offine the page containing the ECC and then the whole decoding chain gets to see the error.
