Change from v3:
- Introduce EFI_VARS_DATA_SIZE_MAX macro.
- Add some description why a scanning/deleting logic is needed.
Currently, when mounting pstore file system, a read callback of efi_pstore
driver runs mutiple times as below.

In case we encounter an error during the mapping of a region, we want to
unwind what we've established so far exactly the way we did the mapping.
This is the PUD part kept deliberately small for easier review.

This is preparatory work in order to be able to map pages into a
specified PGD and not implicitly and only into init_mm.

I also like option 1 ... but I think the id should be a persistent value for
a given saved record. So some func(timestamp, part, count) would be a
good idea. If we try using sequential numbers - and don't manage to
clear out /sys/fs/pstore each time - then we may have the same dmesg
