'memmap' can be used after init, so remove __initdata from it
certainly looks correct to me.

Regarding efi_phys:
'efi_get_time' can be called after init (that "inline ... _init"
on it is confusing to me), and it calls phys_efi_get_time(),
which uses 'efi_phys', so efi_phys should not be marked
as __initdata.

OTOH, phys_efi_set_virtual_address_map() can be marked as __init.
You could add that as an efficiency measure.
