5.15-stable review patch. If anyone has any objections, please let me know.

From: Ilya Leoshkevich iii@linux.ibm.com
commit 5c101153bfd67387ba159b7864176217a40757da upstream.
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.
