Subject: [PATCH v2 00/10] x86/mce: Clean up some x86/mce code

1. Clean up some x86/mce code as below. No functional changes intended.

    - Simplify some code.

    - Remove some unnecessary code.

    - Improve readability for some code.

    - Fix some typos.

    [ Reduce the text segment size by ~116 bytes. ]

2. Pass the following basic tests:

   - Compile test.

   - Correctable/uncorrectable memory errors can be notified via CMCI/MCE interrupts.

   - Correctable/uncorrectable memory errors can be dispatched to the mcelog daemon and the EDAC driver.

   [ Tested on an Intel Sapphire Rapids server. ]

3. This patch series is based on v6.12-rc3.

4. Changes in v2:

   - Collect "Reviewed-by:" tags for patch {1-8,10}.

   - Update the commit message of patch 9 to include the names of all
     variables that don't need NULL pointer initializations.

Thanks Tony for reviewing this patch series.
