Subject: [PATCH v12 01/17] riscv: Rename __switch_to_aux -> fpu
Date: Wed, 21 Sep 2022 14:43:43 -0700	[thread overview]
Message-ID: <20220921214439.1491510-1-stillson@rivosinc.com> (raw)

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.
