From db50c8123469e3eab07e931019bf6d4df2d55c78 Mon Sep 17 00:00:00 2001 From: Ed Maste Date: Wed, 17 Mar 2021 10:10:41 -0400 Subject: [PATCH] arm64: implement COMPAT_FREEBSD32 fill/set dbregs/fpregs On FreeBSD/arm fill_fpregs, fill_dbregs are stubs that zero the reg struct and return success. set_fpregs and set_dbregs do nothing and return success. Provide the same implementation for arm64 COMPAT_FREEBSD32.
