Implement what in Intel-speech is known as "bandwidth
reclamation". It means that we continously poll USB devices
that have a pending transfer instead of polling just once
every ms. This speeds up some transfers at the expense of
using more PCI bandwidth.

at insert time. When asking gibbs for approval for an MFC, this was
his reply:
1) It leaks memory if it can't allocate a path.
2) It defers allocation of aic->path until the call to scan the
bus. This means the path may be NULL when an interrupt occurs
prior to the call to scan the bus (stray bus reset for instance),
which will lead to a panic.
3) The driver in current doesn't recover from the failure to allocate
aic->path. The driver doesn't check during normal operation if
the path is NULL, so again a panic will result.
4) aic_cam_rescan calls malloc with M_WAITOK. aic_cam_rescan is called
from attach where it isn't necessarily safe to sleep.
5) And most importantly, it co-opts the xpt_periph from the driver level.
This was never part of the design (xpt_periph used to be static). Making
a call of this type may completely confuse the XPT if other XPT operations
are ongoing.
In the long term, Justin and Warner agreed to implement solution where
CAM itself will initiate the bus rescan if a new bus is added. For
the time being (and in particular in light of the upcoming 4.5
release), we now have camcontrol available on the boot floppy, and can
have pccardd initiate the rescan through it.

mutex releases to not require flags for the cases when preemption is
not allowed:
The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent
switching to a higher priority thread on mutex releease and swi schedule,
respectively when that switch is not safe. Now that the critical section
API maintains a per-thread nesting count, the kernel can easily check
whether or not it should switch without relying on flags from the
programmer. This fixes a few bugs in that all current callers of
swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from
fast interrupt handlers and the swi_sched of softclock needed this flag.
Note that to ensure that swi_sched()'s in clock and fast interrupt
handlers do not switch, these handlers have to be explicitly wrapped
in critical_enter/exit pairs. Presently, just wrapping the handlers is
sufficient, but in the future with the fully preemptive kernel, the
interrupt must be EOI'd before critical_exit() is called. (critical_exit()
can switch due to a deferred preemption in a fully preemptive kernel.)
I've tested the changes to the interrupt code on i386 and alpha. I have
not tested ia64, but the interrupt code is almost identical to the alpha
code, so I expect it will work fine. PowerPC and ARM do not yet have
interrupt code in the tree so they shouldn't be broken. Sparc64 is
broken, but that's been ok'd by jake and tmm who will be fixing the
interrupt code for sparc64 shortly.

(1) Don't attempt aquire the non-recursive lock sio_lock recursively.
Doing so caused unbounded recursion in some setups. E.g., if DDB,
BREAK_TO_DEBUGGER and WITNESS are configured; if the debugger is
entered using a break, then WITNESS will actually detect the invalid
recursion and will add to it attempting to print a message about it.
(2) Don't use sio_lock before it has been initialized. The old check
(sio_inited != 0) didn't work when sio_inited was boolean because
sio_inited was set too early, and became just wrong when sio_inited
was changed to a tri-state variable in rev.1.348.
