Subject: [PATCH v2 0/3] Cleanup and fixups for vmemmap handling
Date: Wed, 3 Feb 2021 11:47:47 +0100 [thread overview]
Message-ID: <20210203104750.23405-1-osalvador@suse.de> (raw)
Hi,
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.
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
within CONFIG_SPARSEMEM_VMEMMAP
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
