x86/mce: Improve error message when kernel cannot recover, p2
commit 41f035a86b5b72a4f947c38e94239d20d595352a upstream. In c7d606f560e4 ("x86/mce: Improve error message when kernel cannot recover") a case was added for a machine check caused by a DATA access to poison memory from the kernel. A case should have been added also for an uncorrectable error during an instruction fetch in the kernel. Add that extra case so the error message now reads: mce: [Hardware Error]: Machine check: Instruction fetch error in kernel Fixes: c7d606f560e4 ("x86/mce: Improve error message when kernel cannot recover") Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: "H.
