Subject: [PATCH 10/14] MIPS: mm: Un-inline get_new_mmu_context
Date: Sat, 2 Feb 2019 01:43:24 +0000	[thread overview]
Message-ID: <20190202014242.30680-11-paul.burton@mips.com> (raw)
In-Reply-To: <20190202014242.30680-1-paul.burton@mips.com>

In preparation for adding MMID support to get_new_mmu_context() which
will increase the size of the function somewhat, move it from
asm/mmu_context.h into a C file.
