Subject: [PATCH for 6.2 22/49] bsd-user: Move per-cpu code into target_arch_cpu.h
Date: Sat, 7 Aug 2021 15:42:15 -0600 [thread overview]
Message-ID: <20210807214242.82385-23-imp@bsdimp.com> (raw)
In-Reply-To: <20210807214242.82385-1-imp@bsdimp.com>
From: Warner Losh <imp@FreeBSD.org>
Move cpu_loop() into target_cpu_loop(), and put that in
target_arch_cpu.h for each architecture.
