First patch is a bug fix (sort of) we haven't directly seen problems
in the driver, but when adding other bits to it there have been cases
where the compiler re-ordered the access to the MMIO registers. Which
can be a problem.

Second patch adds new type for DDR5 memory

Final patch updates the i10nm EDAC driver to support Sapphire Rapids.

(which also adds some new memory types)

  EDAC/i10nm: Use readl() to access MMIO registers
  EDAC: Add DDR5 new memory type
  EDAC/i10nm: Add Intel Sapphire Rapids server support
