[PATCH v2 12/15] bsd-user/sysarch: Move to using do_freebsd_arch_sysarch


From: Warner Losh
Subject: [PATCH v2 12/15] bsd-user/sysarch: Move to using do_freebsd_arch_sysarch interface
Date: Fri, 8 Oct 2021 17:15:03 -0600

do_freebsd_arch_sysarch() exists in $ARCH/target_arch_sysarch.h for x86.
Call it from do_freebsd_sysarch() and remove the mostly duplicate
version in syscall.c. Future changes will move it to os-sys.c and
support other architectures.
