f4b4a6b096 The EHCI qTD token has a number of error status bits that are not
cleared if the host controller retries the transfer and is successful,
but we were interpreting these bits as indicating a fatal error.
Ignore these error bits, and instead use the HALTED bit to determine
if the transfer failed. Also update the USBD_STALLED detection to
ignore these bits.

172ffe319a - The c_lock in the coda node does not offer any features over the standard
vnode lock.  Remove the c_lock and use the vn lock in its place.
 - Keep the coda lock functions so that the debugging information is
   preserved, but call directly to the vop_std*lock routines for the real
   functionality.

9cbe5da9d5 - It is not legal to access v_data without the vnode lock or interlock

fe68abe291 - The VI_DOOMED flag now signals the end of a vnode's relationship with
the filesystem.  Check that rather than VI_XLOCK.
 - Shorten ffs_reload by one step.  The old check for an inactive vnode
   was slightly racey, and the code which deals with still active vnodes
   is not much more expensive.

b6ee8476d3 - In ufs_mknod(), hold the lock across the call to vgone() as that is now
required.
 - In ufs_close(), don't do the EAGAIN vrele hack, the top layer now calls
   vn_start_write before the lock is acquired as it should.

38d504db44 - Don't drop the lock in ufs_inactive().
- Also in ufs_inactive, don't acquire the vnode interlock where it isn't
   strictly needed.  Also owning the vnode interlock while calling vprint()
   will cause locking assertions to trip.

0463dc9ef1 - Do a vn_start_write in vn_close, we may write if this is the last ref
on an unlinked file.  We can't know if this is the case until after we
   have the lock.
 - Lock the vnode in vn_close, many filesystems had code which was unsafe
   without the lock held, and holding it greatly simplifies vgone().
 - Adjust vn_lock() to check for the VI_DOOMED flag where appropriate.

6703c30bb5 - Remove vx_lock, vx_unlock, vx_wait, etc.
- Add a vn_start_write/vn_finished_write around vlrureclaim so we don't do
   writing ops without suspending.  This could suspend the vlruproc which
   should not be a problem under normal circumstances.
 - Manually implement VMIGHTFREE in vlrureclaim as this was the only instance
   where it was used.
 - Acquire a lock before calling vgone() as it now requires it.
 - Move the acquisition of the vnode interlock from vtryrecycle() to
   getnewvnode() so that if it fails we don't drop and reacquire the
   vnode_free_list_mtx.
 - Check for a usecount or holdcount at the end of vtryrecycle() in case
   someone grabbed a ref while we were recycling.  Abort the recycle, and
   on the final ref drop this vnode will be placed on the head of the free
   list.
 - Move the redundant VOP_INACTIVE protection code into the local
   vinactive() routine to avoid code bloat.
 - Keep the vnode lock held across calls to vgone() in several places.
 - vgonel() no longer uses XLOCK, instead callers must hold an exclusive
   vnode lock.  The VI_DOOMED flag is set to allow other threads to detect
   a vnode which is no longer valid.  This flag is set until the last
   reference is gone, and there are no chances for a new ref.  vgonel()
   holds this lock across the entire function, which greatly simplifies
   logic.
 _ Only vfree() in one place in vgone() not three.
 - Adjust vget() to check the VI_DOOMED flag prior to waiting on the lock
   in the LK_NOWAIT case.  In other cases, check after we have slept and
   acquired an exlusive lock.  This will simulate the old vx_wait()
   behavior.

76d8aa3efe Fix the arrangement of periodic QH tree to give the correct interval

082c434426 In uart_cpu_getdev_console() when determinig whether we should use
a serial console anyway because input-device is set to keyboard and
output-device is set to screen but no keyboard is plugged in don't
assume that a device node for the input-device alias exists. While
this is true for RS232 keyboards (the node of the SCC and UART
respectively which controls the keyboard doesn't disappear when no
keyboard is plugged in) this assumption breaks for USB keyboards.
It's most likely also not true for PS/2 keyboards but OFW doesn't
reliably switch to a serial console when the potential keyboard is
a PS/2 one which isn't plugged in so this couldn't be verified
properly.

56a4dfb981 Fix a long-standing bug in alpha's implementation of busdma. We need to
OR the physical address with alpha_XXX_dmamap_or to get the DMA address,
like the name of the variable suggests.  However, while we were doing
this correctly in the alpha_XXX_dmamap() macro, the busdma code added
the variable to the physical address instead of or'ing it.  Fortunately
and if my math is not entirely wrong, you would need more than 128GB of
RAM and a device able to do DMA in 64bits to experience the bug.
