won't need updating. I can't find any reason for this not to
be the case, but I've taken a more cautious approach to fixing this by
dividing things into three patches.

There's no write access to remove. An existing memslot cannot be updated
to set or clear KVM_MEM_READONLY, and any mappings established in a newly
created or moved read-only memslot will already be read-only.

Consolidate the code and correct the comments to show that the actions
taken to update existing mappings to disable or enable dirty logging

When restoring pages each thread loads pages using a copy of a
pkram_stream initialized by pkram_prepare_load_obj(). Under the hood
each thread ends up fetching and operating on pkram_link pages.

separate memblocks containing preserved pages by setting a new flag
when adding them to the memblock reserved list.

When a kernel is loaded for kexec the address ranges where the kexec
segments will be copied to may conflict with pages already set to be
preserved. Provide a way to determine if preserved pages exist in a
specified range.
