The patch titled
Subject: nommu: remove __GFP_HIGHMEM in vmalloc/vzalloc
has been removed from the -mm tree. Its filename was
nommu-remove-__gfp_highmem-in-vmalloc-vzalloc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Chen Li <chenli@uniontech.com>
Subject: nommu: remove __GFP_HIGHMEM in vmalloc/vzalloc
mm/nommu.c:
void *__vmalloc(unsigned long size, gfp_t gfp_mask)
{
/*
* You can't specify __GFP_HIGHMEM with kmalloc() since kmalloc()
* returns only a logical address.
*/
return kmalloc(size, (gfp_mask | __GFP_COMP) & ~__GFP_HIGHMEM);
}
nommu's __vmalloc just uses kmalloc internally and elimitates
__GFP_HIGHMEM, so it makes no sense to add __GFP_HIGHMEM for nommu's
vmalloc/vzalloc.
