-Subject: [PATCH] mips o32: fix build
-
-Commit 917c2ccf3a67 "Refactor stack pointers" moved mips_REG_* macros
-from linux/mips/arch_regs.h to linux/mips/arch_regs.c because these
-macros are no longer used outside syscall.c or files included by
-syscall.c, but this caused a build regression on mips o32 because
-decode_syscall_subcall() uses mips_REG_SP prior to its definition.
-
-* syscall.c (decode_syscall_subcall): Move ...
-* linux/mips/get_syscall_args.c: ... here.
-* NEWS: Mention this fix.
-
-Reported-by: Baruch Siach <baruch@tkos.co.il>
-Fixes: v4.26~61 "Refactor stack pointers"
