    Subject[PATCH 5.17 0529/1126] libbpf: Fix riscv register names
    Date
    From: Ilya Leoshkevich <iii@linux.ibm.com>

    [ Upstream commit 5c101153bfd67387ba159b7864176217a40757da ]

    riscv registers are accessed via struct user_regs_struct, not struct
    pt_regs. The program counter member in this struct is called pc, not
    epc. The frame pointer is called s0, not fp.

    Fixes: 3cc31d794097 ("libbpf: Normalize PT_REGS_xxx() macro definitions")
