    Subject[PATCH v3 0/6] Fixmap support and MM cleanups
    Date
    From: Anup Patel <anup@brainfault.org>

    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-rc6 and can be found at riscv_fixmap_v3 branch of:
    https://github.com/avpatel/linux.git.

    Changes since v2:
    - Fixed commit description of PATCH6
    - Ensured commit description of all PATCH use upto 72
    characters per line

    Changes since v1:
    - Use more characters per line in changelog of PATCH3
    - Removed #ifndef __ASSEMBLY__ from PATCH5
    - Use more characters per line in commets of PATCH5
    - Added PATCH6 to implement keepinitrd kernel parameter

    Anup Patel (6):
    RISC-V: Move free_initrd_mem() to kernel/setup.c
    RISC-V: Setup init_mm before parse_early_param()
    RISC-V: Move setup_bootmem() to mm/init.c
    RISC-V: Move setup_vm() to mm/init.c
    RISC-V: Implement compile-time fixed mappings
    RISC-V: Implement keepinitrd kernel parameter
