From: Borislav Petkov <b...@suse.de> Hi,
here's a first stab at adding a tracepoint which dumps the decoded MCE string to userspace. The main idea is to have the decoding functionality in the kernel and depending on whether you have userspace consumers listening or not, to dump the error to the tracepoint or to dmesg. In either case, we do the decoding in the kernel and don't need special userspace. Furthermore, adding new CPU support will have to be done only in one place. First 6 patches are cleanups which are good to have regardless, IMO. Any constructive comments and suggestions are appreciated. Thanks. P.S., Thanks to Rostedt for the input!
