Log Message:
Improve our segregs model. Pass 3/3.
Treat %gs the same way we treat %ds/%es/%fs: restore it in INTRFASTEXIT
on 32bit LWPs.
On Xen however, its behavior does not change, because we need to do an
hypercall before INTR_RESTORE_GPRS, and that's too complicated for now.
As a side effect, this change fixes a bug in the ACPI wakeup code; %fs/%gs
were not restored on 32bit LWPs, and chances are they would segfault
shortly afterwards.
Support for USER_LDT on amd64 is almost complete now.
