Subject: [PATCH -v2 01/10] m68k,mm: Remove stray nocache in ColdFire pgalloc
Date: Fri, 31 Jan 2020 13:45:32 +0100 [thread overview]
Message-ID: <20200131125403.481739981@infradead.org> (raw)
In-Reply-To: 20200131124531.623136425@infradead.org
Since ColdFire V4e is a software TLB-miss architecture, there is no
need for page-tables to be mapped uncached. Remove this stray
nocache_page() dance, which isn't paired with a cache_page() and looks
like a copy/paste/edit fail.
