x86/mce: Improve error message when kernel cannot recover, p2
commit41f035a86b
upstream. Inc7d606f560
("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:c7d606f560
