Subject[PATCH v3 0/3] Cleanup and fixups for vmemmap handling

this series contains cleanups to remove dead code that handles
unaligned cases for 4K and 1GB pages (patch#1 and pathc#2) when
removing the vemmmap range, and a fix (patch#3) to handle the case
when two vmemmap ranges intersect a PMD.

More details can be found in the respective changelogs.

v2 -> v3:
- Make sure we do not clear the PUD entry in case
we are not removing the whole range.
- Add Reviewed-by

v1 -> v2:
- Remove dead code in remove_pud_table as well
- Addessed feedback by David
- Place the vmemap functions that take care of unaligned PMDs

Oscar Salvador (3):
x86/vmemmap: Drop handling of 4K unaligned vmemmap range
x86/vmemmap: Drop handling of 1GB vmemmap ranges
x86/vmemmap: Handle unpopulated sub-pmd ranges
