#     Merge tag 'riscv-for-linus-5.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#      "A handful of fixes for 5.12:
#     
#        - fix the SBI remote fence numbers for hypervisor fences, which had
#          been transcribed in the wrong order in Linux. These fences are only
#          used with the KVM patches applied.
#     
#        - fix a whole host of build warnings, these should have no functional
#          change.
#     
#        - fix init_resources() to prevent an off-by-one error from causing an
#          out-of-bounds array reference. This was manifesting during boot on
#          vexriscv.
#     
#        - ensure the KASAN mappings are visible before proceeding to use
#          them"
