Add UAPI and kernel plumbing to expose the Zicbop extension presence
and its block size through sys_hwprobe(). The interface mirrors
Zicbom/Zicboz. This allows userspace to safely discover and optimize
for Zicbop when available.

Hi all,

It’s been about two weeks since I posted this patch.
Could someone take a look when convenient and let me know if there are
any concerns or improvements needed?

Thanks for your attention.
