mce_usable_address() does a bunch of basic sanity checks to verify whether the address reported with the error is usable for further processing. However, we do check MCi_STATUS[MISCV] and that is not needed on AMD as that bit says that there's additional information about the logged error in the MCi_MISCj banks. But we don't need that to know whether the address is usable - we only need to know whether the physical address is valid - i.e., ADDRV. On Intel the MISCV bit is needed to perform additional checks to determine whether the reported address is a physical one, etc. Signed-off-by: Borislav Petkov <bp@suse.de> Cc: Yazen Ghannam <yazen.ghannam@amd.com> Cc: Tony Luck <tony.luck@intel.com> Cc: linux-edac <linux-edac@vger.kernel.org> Link: http://lkml.kernel.org/r/20170418183924.6agjkebilwqj26or@pd.tnic Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
