#     Merge tag 'riscv-for-linus-5.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux into master
#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "Two fixes:
#     
#        - 16KiB kernel stacks on rv64, which fixes a lot of crashes.
#     
#        - Rolling an mmiowb() into the scheduler, which when combined with
#          Will's fix to the mmiowb()-on-spinlock should fix the PREEMPT
#          issues we've been seeing"
#     
#     * tag 'riscv-for-linus-5.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
