#     Merge tag 'riscv/for-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Paul Walmsley:
#      "Several fixes for RISC-V:
#     
#        - Fix function graph trace support
#     
#        - Prefix the CSR IRQ_* macro names with "RV_", to avoid collisions
#          with macros elsewhere in the Linux kernel tree named "IRQ_TIMER"
#     
#        - Use __pa_symbol() when computing the physical address of a kernel
#          symbol, rather than __pa()
#     
#        - Mark the RISC-V port as supporting GCOV
#     
#       One DT addition:
#     
#        - Describe the L2 cache controller in the FU540 DT file
#     
#       One documentation update:
#     
#        - Add patch acceptance guideline documentation"
