[PATCH 00/11] Introduce CONFIG_PLATFORM_OP to disable platform_op hypercalls

[Jiqian Chen <Jiqian.Chen@xxxxxxx>]

Hi all,
This is a continuation of the disabling some hypercalls handling code series.
https://lore.kernel.org/xen-devel/20250704092952.822578-1-Penny.Zheng@xxxxxxx/

It can be beneficial for some dom0less systems to further reduce Xen footprint
via disabling some hypercalls handling code, which may not to be used &
required in such systems. Each hypercall has a separate option to keep
configuration flexible.

Options to disable hypercalls:
- sysctl
- domctl
- hvm
- physdev
- platform_op

This is for platform_op.
