SVN rev 181752 on 2008-08-15 09:08:35Z by kib
MFC r177535 by peter:
(Micro)optimization of cpu_switch for amd64.
Because r173004 (pure kernel threads) is not MFCed to stable/7, I use
P_KTHREAD flag from curthread->td_proc->p_flag instead of TDP_KTHREAD
flag from curthread->td_pflags to test whether the fs/gs bases need to
be restored [1].
No objections for MFC from: peter
Suggested by: jhb [1]
MFC r180992:
Bring back the save/restore of the %ds, %es, %fs and %gs registers for
the 32bit images on amd64.
The end result is almost complete syncronization of the
amd64/amd64/cpu_switch.S between head and stable/7, besides TDP_KTHREAD
difference.
