0bea487cfa Add a wrapper for a function that takes and releases the adapter
lock around a call to the original function.  Make the timeout
function in callout_reset() use the wrapped function to avoid a
lock assertion panic.

515d4440fe Add facilities for tuning the "em" driver's interrupt delays without
recompiling the driver.  See the comments near the top of "if_em.h"
for descriptions of these delays.  Four new loader tunables control
the system-wide default values:

    hw.em.tx_int_delay
    hw.em.rx_int_delay
    hw.em.tx_abs_int_delay
    hw.em.rx_abs_int_delay

The tunables are specified in microseconds.  The valid range is
0-67108 usec., and 0 means that the timer is disabled.

There are also four new sysctls (actually, a set of four for each
"em" device in the system) to query and change the interrupt delays
after the system is up:

    hw.em0.tx_int_delay
    hw.em0.rx_int_delay
    hw.em0.tx_abs_int_delay (not present for 82542/3/4 adapters)
    hw.em0.rx_abs_int_delay (not present for 82542/3/4 adapters)

It seems to be OK to change these values even while the adapter is
passing traffic.

dbe4792865 The em(4) driver has been converted to busdma and doesn't use
vtophys() anymore, so remove the alpha hack which defines

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.
