#     Merge tag 'riscv/for-v5.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Paul Walmsley:
#      "Three fixes for RISC-V:
#     
#        - Don't free and reuse memory containing the code that CPUs parked at
#          boot reside in.
#     
#        - Fix rv64 build problems for ubsan and some modules by adding
#          logical and arithmetic shift helpers for 128-bit values. These are
#          from libgcc and are similar to what's present for ARM64.
#     
#        - Fix vDSO builds to clean up their own temporary files"
#     
#     * tag 'riscv/for-v5.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
#       riscv: Less inefficient gcc tishift helpers (and export their symbols)
#       riscv: delete temporary files
#       riscv: make sure the cores stay looping in .Lsecondary_park
