Subject: [PATCH 1/4] rcutorture/nolibc: fix the clobbered registers in the MIPS syscall definition
Date: Sat, 29 Dec 2018 19:02:16 +0100	[thread overview]
Message-ID: <20181229180218.15798-2-w@1wt.eu> (raw)
In-Reply-To: <20181229180218.15798-1-w@1wt.eu>

A last-minute checkpatch cleanup caused most of list of clobbered
registers to be lost in the MIPS syscall definition. As it is right
now the code is not used on MIPS, but it's better to fix it before
it gets used.
