cper.c contains code to decode and print "Common Platform Error Records".
Originally added under drivers/acpi/apei because the only user was in that
same directory - but now we have another consumer, and we shouldn't have
to force CONFIG_ACPI_APEI get access to this code.

Since CPER is defined in the UEFI specification - the logical home for
this code is under drivers/firmware/efi/

efivars.c has grown far too large and needs to be divided up. Create a
new directory and move the persistence storage code to efi-pstore.c now
that it uses the new efivar API. This helps us to greatly reduce the
size of efivars.c and paves the way for moving other code out of
efivars.c.

Note that because CONFIG_EFI_VARS can be built as a module efi-pstore
must also include support for building as a module.
