5c57068fcc Fix mistakes in Linux ww_mutex code. 
I wrote some cases for the WW_WANTOWN state forgetting that there is
an acquisition context associated with it.

- On acceptance of a lock, allow WW_WANTOWN as well as WW_CTX.
- On unlock when WW_WANTOWN, decrement the context's acquire count.

Fixes KASSERT(ctx->wwx_acquired == 0) failure in ww_acquire_fini, and
would fix unlikely but possible kasserts in ww_mutex_lock* if another
lwp swoops in to lock without a context quickly enough.

While here, add some comments and kassert up the wazoo.

faa04ab45f Disable VGA plane after vga_cndetach. 
Disabling the VGA plane requires access to the VGA registers, which
don't become available until vga_cndetach.  Oops!

7c2a9a0993 Improve USB debugging with USBHIST based on KERNHIST. 
Convert some DPRINTFs to USBHIST_LOG and allow usbdebug, ehcidebug and
umassdebug to be changed via sysctl.

Remove the #define mess in usb.h.

This was started by mrg@ and updated by reinoud@

a2eca9ebfa Make Linux io_mapping actually work. 
Can't use bus_space_map/bus_space_unmap in interrupt context, where
Linux uses this io_mapping abstraction.  Instead, do uvm_km_alloc up
front and then use bus_space_mmap/pmap_kenter_pa to map it.

XXX Should bus_space_reserve the region (but that's x86-only for now).
XXX Should use direct map if possible.
XXX Should set an MTRR WC too in case of direct map or no PAT.

84eae6ff7f Fix two mistakes in previous. 
- i915_error_wake_up is given irq_lock, so it need not take that.
- Unlock irq_lock on exit from i915_hangcheck_elapsed if ring_hung.

XXX This introduces the lock order irq_lock -> pending_flip_lock.
How about just using irq_lock for pending flips?

- viafb (maybe steal unichromefb and adapt attachment structure)
- actually run it (no hardware here)

f40a74cd43 Drop take the {ttm,gem} vmobjlock in the fault handler. 
- We don't need this lock.
- uvm does nothing between taking it and calling the fault handler.
- Now that the uvm_aobj shares vmobjlock with the {ttm,gem} uvm
  object, we must not hold the lock when we call uvm_obj_wirepages on
  the uvm_aobj.
