Subject: [PATCH 0/2] Extend size of the MCE Records pool

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.

  x86/MCE: Extend size of the MCE Records pool
  x86/MCE: Add command line option to extend MCE Records pool
