Repair some races in IPI handling:
1. Make sure IPI mask is set before sending the IPI
2. Operate atomically on PS3 PIC outstanding interrupt list
3. Make sure IPIs are EOI'ed before, not after, processing. Without this,
a second IPI could be sent partway through processing the first one,
get erroneously acknowledge by the EOI to the first, and be lost. In
particular in the case of smp_rendezvous(), this can be fatal.
In combination, this makes the PS3 boot SMP again. It probably also fixes

With the new-and-improved vm_fault_copy_entry() (r265843), we can always
avoid soft page faults when adding write access to user wired entries in
vm_map_protect(). Previously, we only avoided the soft page fault when
the underlying pages were copy-on-write. In other words, we avoided the
pages faults that might sleep on page allocation, but not the trivial
page faults to update the physical map.
On a fork allow read-only wired pages to be copy-on-write shared between
the parent and child processes. Previously, we copied these pages even
though they are read only. However, the reason for copying them is
historical and no longer exists. In recent times, vm_map_protect() has
developed the ability to copy pages when write access is added to wired
copy-on-write pages. So, in this case, copy-on-write sharing of wired
pages is not to be feared. It is not going to lead to copy-on-write
faults on wired memory.

Fix TLR (Transport Layer Retry) support in the mps(4) and mpr(4) drivers.
TLR is necessary for reliable communication with SAS tape drives.
This was broken by change 246713 in the mps(4) driver. It changed the
cm_data field for SCSI I/O requests to point to the CCB instead of the data
buffer. So, instead, look at the CCB's data pointer to determine whether
or not we're talking to a tape drive.
Also, take the residual into account to make sure that we don't go off the
end of the request.

Fix a bug in the HPET emulation where a timer interrupt could be lost when the
