The patch titled
mm: remove vmalloc_to_pfn
has been removed from the -mm tree. Its filename is
mm-remove-vmalloc_to_pfn.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Nick Piggin <npiggin@xxxxxxx>
vmalloc_to_pfn no longer has any callers left in the kernel. It was
previously used so remap_pfn_range can be used on vmalloc memory, but is
obsolete with the introduction of remap_vmalloc_range.
