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!

Borislav Petkov (8):
  EDAC, mce_amd: Rename decode_smca_errors() to decode_smca_error()
  EDAC, mce_amd: Get rid of most struct cpuinfo_x86 uses
  EDAC, mce_amd: Get rid of local var in amd_filter_mce()
  seq_buf: Add seq_buf_clear_buf()
  seq_buf: Export seq_buf_printf() to modules
  EDAC, mce_amd: Convert to seq_buf
  EDAC, mce_amd: Add a simple tracepoint dumping a decoded string
  EDAC, mce_amd: Issue the decoded info through the TP or printk
