[PATCH 0/3] Fix and cleanup for 32-bit PV sysexit
The first patch fixes Xen PV regression introduced by 32-bit rewrite. Unlike the
earlier version it uses ALTERNATIVE instruction and avoids using xen_sysexit
(and sysret32 in compat mode) pv ops, as suggested by Andy. (I ended up patching
TEST with XOR to avoid extra NOPs, even though I said yesterday it would be
wrong. It's not wrong)
As result of this patch irq_enable_sysexit and

[PATCH v2 0/3] Fix and cleanup for 32-bit PV sysexit
The first patch fixes Xen PV regression introduced by 32-bit rewrite. Unlike the
earlier version it uses ALTERNATIVE instruction and avoids using xen_sysexit
(and sysret32 in compat mode) pv ops, as suggested by Andy.
As result of this patch irq_enable_sysexit and usergs_sysret32 pv ops are not
used anymore by anyone and so can be removed.
