Subject: [PATCH -next v14 01/19] riscv: Rename __switch_to_aux -> fpu
Date: Fri, 24 Feb 2023 17:01:00 +0000	[thread overview]
Message-ID: <20230224170118.16766-2-andy.chiu@sifive.com> (raw)
In-Reply-To: <20230224170118.16766-1-andy.chiu@sifive.com>

From: Guo Ren <ren_guo@c-sky.com>

The name of __switch_to_aux is not clear and rename it with the
determine function: __switch_to_fpu. Next we could add other regs'
switch.
