ATI EHCI controllers exhibit simmilar stall issues and require
this dropped interrupts workaround. Be verbose about it.

VIA and ATI EHCI controllers.

long the string is in userspace, afterwards we call malloc(M_WAITOK),
which could sleep for an unknown amount of time. Check the return
value of copyin(9) just to be sure that nothing has changed during that
time.

an interrupt appears to occur before the transfer has been marked
as completed. This caused umass transfers to get stuck, especially
when writing large files. The workaround sets up a timer that
rechecks for missed completed transfers if some operations are still
pending. Other suggested workarounds, such as performing a PCI read
immediately after acknowledging the interrupts, do not appear to
help.

Since we are using vfs_busy() on a freshly allocated mount structure, use
(void) to show that we do not care about the return value.

ipq_zone, to allocate fragment headers from, rather than using cast mbuf
storage. This was one of the few remaining uses of mbuf storage for
local data structures that relied on dtom(). Implement the resource
limit on ipq's using UMA zone limits, but preserve current sysctl
semantics using a sysctl proc.

same behavior to be controlled by the sysctls, hw.syscons.kbd_kbdkey
and hw.syscons.kbd_reboot respectively.
Apologies to the submitter for taking so long to commit this simple
change.

I couldn't find the ID for the EG1064 anywhere in our sources
so I removed the reference for now.

an application to upon a tape (yea, even the non-control device) even if
it cannot establish a mount session. If the open cannot establish a mount
session and O_NONBLOCK was specified, the tape becomes 'open pending mount'.
All I/O operations that would require access to a tape thereafter until
a close attempt to initiate the mount session. If the mount session succeeds,
the tape driver transitions to full open state, else returns an appropriate
I/O error (ENXIO).
At the same time, add a change that remembers whether tape is being opened
read-only. If so, disallow 'write' operations like writing filemarks that
bypass the normal read-only filtering operations that happen in the write(2)
syscall.
