#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#     
#      - A fix for a lockdep issue to avoid an asserting triggering during
#        early boot. There shouldn't be any incorrect behavior as the system
#        isn't concurrent at the time.
#     
#      - The addition of a missing fence when installing early fixmap
#        mappings.
#     
#      - A corretion to the K210 device tree's interrupt map.
#     
#      - A fix for M-mode timer handling on the K210.
