someone screwed something up
...aravirt_ops.write_gdt_entry = lguest_write_gdt_entry;
> paravirt_ops.write_idt_entry = lguest_write_idt_entry;
And here it is:
==
The prototype for paravirt_ops write_lgt_entry, write_gdt_entry and
write_idt_entry was type-corrected, so change lguest to match. We can
also use the "write_dt_entry" which was exported by that same cleanup
patch, rather than write our own.

[PATCH 0/19] desc_struct integration
Hi,
this is a series of patches that unify the struct desc_struct and friends
across x86_64 and i386. As usual, it provides paravirt capabilities as a
side-effect for x86_64.
I consider the main goal, namely, of unifying the desc_struct, an ongoing
effort, being this the beginning. A lot of old code has to be touched to
accomplish that.
I don't consider this patch ready for inclusion.

[PATCH 1/4] x86 paravirt_ops: create no_paravirt.h for native ops
(Andrew, please sit these in the -mm tree for cooking)
Create a paravirt.h header for (almost) all the critical operations
which need to be replaced with hypervisor calls.
For the moment, this simply includes no_paravirt.h, where all the
native implementations now live.

These first two patches are the fundamentals, stolen mainly from the
VMI patches: removing assumptions about the kernel running in ring 0,
and macro-izing all the obvious para-virtualize-needing insns. The
