Thread-topic: [Xen-devel] set_fast_trap() in xenlinux
User-agent: Microsoft-Entourage/11.4.0.080122
Normal trap handlers registered on vector 0x80 are automatically 'faster'. set_fast_trap() disappeared ages ago.

Can anyone please tell me whether HYPERVISOR_set_fast_trap() is used in linux-2.6.18.hg which runs as dom0 on xen?
I searched through the code but could not find it there...
Are fast handlers used as default?...

Also, I found "fastcall" written in the prototype of many functions...does it have any relation with fastcalls??
