The patch titled
Subject: mm/vmalloc: add vmap_range_noflush variant
has been removed from the -mm tree. Its filename was
mm-vmalloc-add-vmap_range_noflush-variant.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Nicholas Piggin <npiggin@xxxxxxxxx>
Subject: mm/vmalloc: add vmap_range_noflush variant
As a side-effect, the order of flush_cache_vmap() and
arch_sync_kernel_mappings() calls are switched, but that now matches the
other callers in this file.
