This patchset extends size of the existing MCE records pool to ensure
that MCE records are not dropped, particularly on systems with higher
CPU count.

This is a followup of the below discussion:
https://lore.kernel.org/linux-edac/20231011163320.79732-1-sironi@amazon.de/

The fist patch extends the size of MCE Records pool in accordance to the
CPU count of the system.

The second patch adds a new command line parameter to extend the size of
MCE Records pool by a predetermined number of pages.
