zfs: Wire sha512 offload to the build
FreeBSD main just got the CPUID_STDEXT4_SHA512 define.
OpenZFS PR #18732
This commit breaks boot for me. The kernel can't open the zroot pool,
leading to the familiar mountroot> prompt. And in a UFS-root VM, I
can't load the ZFS kernel module. It fails with:
link_elf_obj: symbol zfs_sha512_transform_sha512ext undefined
linker_load_file: /boot/kernel/zfs.ko - unsupported file type
On both systems, the CPU is a Ryzen 9 5950X, which does not support AVX-512.
Could we please revert the change for now?
I've reverted the commit. I may not have much time nearest days, so if
anybody wish to investigate it -- please do.
