Hi Andrew, Now that 5.12-rc1 is out, and as discussed, here there is a new version on top of it. Please, consider picking up the series. Thanks Original cover letter: ---- Hi, this series contains cleanups to remove dead code that handles unaligned cases for 4K and 1GB pages (patch#1 and patch#2) when removing the vemmmap range, and a fix (patch#3) to handle the case when two vmemmap ranges intersect the same PMD. More details can be found in the respective changelogs. v3 -> v4: - Rebase on top of 5.12-rc1 as Andrew suggested - Added last Reviewed-by for the last patch 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 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 arch/x86/mm/init_64.c | 189 +++++++++++++++++++++++++++++++------------------- 1 file changed, 118 insertions(+), 71 deletions(-) -- 2.16.3
