Merge branch 'acpi-apei'

Merge ACPI APEI support updates for 6.20-rc1/7.0-rc1:

 - Make read-only array non_mmio_desc[] static const (Colin Ian King)

 - Prevent the APEI GHES support code on ARM from accessing memory out
   of bounds or going past the ARM processor CPER record buffer (Mauro
   Carvalho Chehab)

 - Prevent cper_print_fw_err() from dumping the entire memory on systems
   with defective firmware (Mauro Carvalho Chehab)

 - Improve ghes_notify_nmi() status check to avoid unnecessary overhead
   in the NMI handler by carrying out all of the requisite preparations
   and the NMI registration time (Tony Luck)

 - Refactor the GHES driver by extracting common functionality into
   reusable helper functions to reduce code duplication and improve
   the ghes_notify_sea() status check in analogy with the previous
   ghes_notify_nmi() status check improvement (Shuai Xue)

 - Make ELOG and GHES log and trace consistently and support the CPER
   CXL protocol analogously (Fabio De Francesco)

 - Disable KASAN instrumentation in the APEI GHES driver when compile
   testing with clang < 18 (Nathan Chancellor)

 - Let ghes_edac be the preferred driver to load on  __ZX__ and _BYO_
   systems by extending the platform detection list in the APEI GHES
   driver (Tony W Wang-oc)
