Subject: [merged] mips-mm-highmem-use-set_pte-for-kmap_local.patch removed from -mm tree
Date: Mon, 25 Jan 2021 13:35:27 -0800 [thread overview]
Message-ID: <20210125213527.c8xPNKChB%akpm@linux-foundation.org> (raw)
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.
