Log Message:
document the status of usbmp branch. major remaining tasks:
- port slhci, adm5120 usb and rump usb host controllers [*]
- implement usb_detach_wait/wakeup based upon cv/mutex [*]
- port drivers that use tsleep/wakeup to modern facilities
- port cdev/bdev drivers to D_MPSAFE
- update callouts to CALLOUT_MPSAFE
- test more devices [*]
only really more testing is necessary at this point, all the above
can be done after merging this code into -current. items marked
with [*] are planned to be done before this.

+the majority of the USB MP device interface is documented in usbdivar.h.

+
+host controller porting:
+ - slhci
+ - arch/mips/adm5120/dev/ahci.c
+ - rump/dev/lib/libugenhc/ugenhc.c
+
+
+use /* XXXSMP ok */ markers for non-SMP-safe host controller driver uses.
+eg, "if (lock_ptr) mutex_enter(lock_ptr); else s = splusb();"
+
+
+add lots of asserts
+
+
+wakeup removal core:
+ - usb_detach_wait/wakeup() -> add a usb_detach_cvwait/broadcast() that
+ take a mutex
+
+
+convert uhidev users to MPSAFE:
+ ucycom(4)
+ - own cdevsw that isn't D_MPSAFE; need to check intr handlers
+
+ uhid(4)
+ - needs some locking here (not completely tested changes)
+
+ ukbd(4)
+ ums(4)
+ uts(4)
+ pbms(4)
+ - depends upon wscons? check intr
+
+ uyurex(4)
+ - sysmon -- hm?
