Add missing machine/md_var.h to spl/sys/simd_aarch64.h and spl/sys/simd_arm.h In spl/sys/simd_x86.h, PCB_FPUNOSAVE exists only on amd64, use PCB_NPXNOSAVE on i386 In FreeBSD sys/elf_common.h redefines AT_UID and AT_GID on FreeBSD, we need a hack in vnode.h similar to Linux. sys/simd.h needs to be included early. In zfs_freebsd_copy_file_range() we pass a (size_t *)lenp to zfs_clone_range() that expects a (uint64_t *) Allow compiling armv6 world by limiting ARM macros in sha256_impl.c and sha512_impl.c to __ARM_ARCH > 6 Reviewed-by: Alexander Motin <mav@FreeBSD.org> Reviewed-by: Tino Reichardt <milky-zfs@mcmilk.de> Reviewed-by: Richard Yao <richard.yao@alumni.stonybrook.edu> Reviewed-by: Pawel Jakub Dawidek <pawel@dawidek.net> Reviewed-by: Signed-off-by: WHR <msl0000023508@gmail.com> Signed-off-by: Martin Matuska <mm@FreeBSD.org> Closes #14674
