The patch titled
virtual-memmap-on-sparsemem-v3-generic-virtual fix
has been removed from the -mm tree. Its filename was
virtual-memmap-on-sparsemem-v3-generic-virtual-fix.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: virtual-memmap-on-sparsemem-v3-generic-virtual fix
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx>
Fixes #error condition.
This check's meaning is:
--for 32bits--
4 (struct page's alignment) * PAGES_PER_SECTION % PAGE_SIZE == 0
--for 64bits--
8 (struct page's alignment) * PAGES_PER_SECTION % PAGE_SIZE == 0
Then, vmem_map is aligned per section.
This check may be removed if I (or someone) can write clean patch
for not aligned vmem_map.
