+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.
