#     Merge tag 'riscv-for-linux-5.6-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "This contains a handful of RISC-V related fixes that I've collected
#       and would like to target for 5.6-rc4:
#     
#        - A fix to set up the PMPs on boot, which allows the kernel to access
#          memory on systems that don't set up permissive PMPs before getting
#          to Linux. This only effects machine-mode kernels, which currently
#          means only NOMMU kernels.
#     
#        - A fix to avoid enabling supervisor-mode interrupts when running in
#          machine-mode, also only for NOMMU kernels.
#     
#        - A pair of fixes to our KASAN support to avoid corrupting memory.
#     
#        - A gitignore fix.
#     
#       This boots on QEMU's virt board for me"

#     * tag 'riscv-for-linux-5.6-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
#       riscv: adjust the indent
#       riscv: allocate a complete page size for each page table
#       riscv: Fix gitignore
#       RISC-V: Don't enable all interrupts in trap_init()
#       riscv: set pmp configuration if kernel is running in M-mode
