Xen is requiring 64-bit machines today and since Xen 4.14 it can be
built without 32-bit PV guest support. There is no need to carry the
burden of 32-bit PV guest support in the kernel any longer, as new
guests can be either HVM or PVH, or they can use a 64 bit kernel.

The long term plan has been to replace Xen PV guests by PVH. The first
victim of that plan are now 32-bit PV guests, as those are used only
rather seldom these days. Xen on x86 requires 64-bit support and with

need to keep 32-bit

Some x86 CPUs speculatively execute beyond indirect CALL/JMP instructions.
With CONFIG_INDIRECT_THUNK / Retpolines, indirect CALL/JMP instructions are
converted to direct CALL/JMP's to __x86_indirect_thunk_REG(), leaving just a
