#     Merge tag 'riscv-for-linus-5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#     
#      - A fix to avoid undefined behavior when stack backtracing, which
#        manifests in GCC as incorrect stack addresses
#     
#      - A few fixes for the XIP kernels
#     
#      - A fix to tracking NUMA state on CPU hotplug
#     
#      - Support for the recently relesaed binutils-2.38, which changed the
#        default ISA version to one without CSRs or fence.i in 'I' extension
#
