x86/mce: Improve error message when kernel cannot recover, p2
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
