The patch titled
Subject: mips/mm/highmem: use set_pte() for kmap_local()
has been removed from the -mm tree. Its filename was
mips-mm-highmem-use-set_pte-for-kmap_local.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Thomas Gleixner <tglx@linutronix.de>
Subject: mips/mm/highmem: use set_pte() for kmap_local()
set_pte_at() on MIPS invokes update_cache() which might recurse into
kmap_local(). Use set_pte() like the original MIPS highmem implementation
did.
