--0-628401884-1020610584=:70631 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline while this commit fixes problem in UP system, in SMP system there is still a scenario that one cpu running VM86 client gets fault and other cpu in kernel mode calling bios service gets fault too, the system can not correctly handle the scenario in trap.c, a solution is putting in_vm86call into per-cpu area as you previous stated. I have a patch attached, it's for CURRERNT branch.
