Domctl series as a fix to PV_SHIM_EXCLUSIVE, was: [PATCH] xen/x86: move domctl.o out of PV_SHIM_EXCLUSIVE

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi Oleksii,

We previously discussed the PV_SHIM_EXCLUSIVE build issue on Matrix
and agreed on resolving it after the feature freeze as a fix. This
conversation took place before the feature freeze was rescheduled to
September 5. I am documenting this on xen-devel both for record-keeping
and because Matrix is currently offline. I am proceeding under the
assumption that the conclusions from that discussion still apply.

I would like to request an additional clarification. While there is no
consensus among the maintainers on the preferred short-term compromise,
there is agreement that reviewing and committing the domctl series [1]
in time would be the best outcome. (Together with unifying CONFIG_SYSCTL
and CONFIG_DOMCTL into a single CONFIG_MGMT_HYPERCALLS for simplicify.)

Are you still OK with us going ahead with reviewing and committing the
domctl series as a fix to the PV_SHIM_EXCLUSIVE issue, potentially going
past the feature freeze by a week?

Many thanks!

Cheers,

Stefano
