Subject: [PATCH tip/core/rcu 05/10] rcutorture/nolibc: Fix the clobbered registers in the MIPS syscall definition

From: Willy Tarreau <w@....eu>

A last-minute checkpatch cleanup caused most of list of clobbered
registers to be lost in the MIPS syscall definition. Although this code
is not yet used on MIPS, it is nevertheless better to fix it before it
does get used.
