Subject: [PATCH 0/5] Fixmap support and MM cleanups
Date:   Mon,  7 Jan 2019 21:40:42 +0530
Message-Id: <20190107161047.10516-1-anup@brainfault.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patchset does:
1. Moves MM related code from kernel/setup.c to mm/init.c
2. Implements compile-time fixed mappings

Using fixed mappings available, we can now get earlyprints
even without SBI calls. For example, we can use kernel
parameter "earlycon=uart8250,mmio,0x10000000" to get early
prints on QEMU virt machine without using SBI calls.

The patchset is tested on QEMU virt machine. It is based on
Linux-5.0-rc1 and can be found at riscv_fixmap_v1 branch of:
https://github.com/avpatel/linux.git.
