We have had a hard coded limit of 32 machine check records since the
dawn of time. But as numbers of cores increase, it is possible for
more than 32 errors to be reported before a user process reads from
/dev/mcelog. In this case the additional errors are lost.
Keep 32 as the minimum. But tune the maximum value up based on the
number of processors.

x86/mce: Unify pr_* prefix2018-12-06T11:04:52ZBorislav Petkovbp@suse.de2018-12-05T20:05:13Zurn:sha1:3bfaf95cb1fe81872df884956c704469e68a5bee
Move the pr_fmt prefix to internal.h and include it everywhere. This
way, all pr_* printed strings will be prepended with "mce: ".
No functional changes.

x86/mce: Streamline MCE subsystem's naming2018-12-05T17:00:29ZBorislav Petkovbp@suse.de2018-11-18T14:15:05Zurn:sha1:21afaf181362b4aeb5be72705d2914673b336149
Rename the containing folder to "mce" which is the most widespread name.
Drop the "mce[-_]" filename prefix of some compilation units (while
others don't have it).
This unifies the file naming in the MCE subsystem:
mce/
|-- amd.c
|-- apei.c
|-- core.c
|-- dev-mcelog.c
|-- genpool.c
|-- inject.c
|-- intel.c
|-- internal.h
|-- Makefile
|-- p5.c
|-- severity.c
|-- therm_throt.c
|-- threshold.c
`-- winchip.c
No functional changes.
