Subject: [PATCH v4 46/54] ARM: mmu64: Convert flags in arch_remap_range()
Date: Mon, 11 Jun 2018 18:53:18 -0700 [thread overview]
Message-ID: <20180612015326.26192-47-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180612015326.26192-1-andrew.smirnov@gmail.com>
Flags passed to arch_remap_range() are architecture independent, so it
can't be passed as is to map_region(). Add code to do the proper
conversion to avoid subtle bugs that this confusion brings.
