Subject: [RESEND v3 46/52] ARM: mmu64: Convert flags in arch_remap_range()
Date: Thu,  7 Jun 2018 06:01:02 -0700	[thread overview]
Message-ID: <20180607130108.5339-47-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180607130108.5339-1-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.
