Hi all,
I'm trying ot figure out what that's all about? I see in 64 PV domU, it's
being checked prior to returning from syscall. On the xen side, I see it tied
to supervisor_mode_kernel, but the only info I find is changelog comment which
suggests it's purpose is to allow dom0 run in ring 0... So why the check in a
domU kernel?
Thanks,
Mukesh
