o Always release the resources on device detach.
o Attach resources the same with driver added as we do we do in the insert
case (maybe this should be a routine).
o signal the wakeup of the thread on resume instead of trying to force an
interrupt.
o Minor debug hacks.
o use 0xffffffff instead of -1 for uint32_t items.
o Don't complain when we're asked to detach no cards. This is normal.
o Eliminate the now worthless second parameter to card_detach_card.
o minor style(9)isms
Some of these patches may be from: iwasaki-san, jhb, iadowse
o It turns out that we always need to try to route the interrupts for
the case where the $PIR tells us there can be only one. Some machines
require this, while others fail when we try to do this (bogusly, imho).
Since we have no apriori way of knowing which is which, we always try to
do the routing and hope for the best if things fail.
o Add some additional comments that state the obvious, but amplify it in
non-obvious ways (judging from the questions I've gotten).
This should un-break older laptops that still have to use PCIBIOS to route
interrupts.

Fix a couple of resulting printf breakages
Bug found by: phk using Flexlint
checking for "path == NULL" (like ffs) rather than MNT_ROOT. Otherwise
when you try and do an update or mountd does an NFS export, the remount
fails because the code tries to mount a fresh rootfs and gets an EBUSY.
The same bug is in 4.x (which is where I found it).
Sanity check by: mux
function takes an int * parameter, not a size_t * parameter.
Arguably, it should rather take a size_t *, but that would
require changing the uio_resid field of struct uio to be a size_t
instead of an int, which I don't want to do that close to
5.0-RELEASE.

skip those. This handles the Protective MBR (PMBR) which consists
of a single partition of type 0xEE that covers the whole disk and
as such protects the GPT partitioning. We allow other partitions to
be present besides partitions of type 0xEE and as such interpret
partition type 0xEE as a "hands-off" partition only.
While here, fix g_mbrext_dumpconf to test if indent is NULL and
dump the data in a form that libdisk can grok. Change the logic
in g_mbr_dumpconf to match that of g_mbrext_dumpconf. This does
not change the output, but prevents a NULL-pointer dereference
when indent == NULL && pp == NULL.
expected under -current. This is a problem for GEOM because the up/down
threads cannot sleep waiting for memory to become free. The reason they
cannot sleep is that paging things out to disk may be the only way we can
clear up some RAM. Nice catch-22 there.
Implement a rudimentary ENOMEM recovery strategy: If an I/O request
fails with an error code of ENOMEM, schedule it for a retry, and
tell the down-thread to sleep hz/10 to get other parts of the system
a chance to free up some memory, in particular the up-path in GEOM.
All caches should probably start to monitor malloc(9) failures using the new
malloc_last_fail() function, and release when it indicates congestion.

I have seen at least one case where the bio_cmd field was zero once the

the culprit in the backtrace.

nfsm_srvpathsiz. This macro plucks a length out of an rpc request and
verifies that its size does not exceed NFS_MAXPATHLEN. If it does
it generates an ENAMETOOLONG response.
- Use this macro, and the existing nfsm_srvnamsiz macro in two places
where we deal with paths passed in by the client.
This fixes a linux interoperability bug. Linux was sending oversized path
components which would cause us to ignore the request all together. This
causes linux to hang indefinitly while it waits for a response. This
could still happen in other cases where we error out with EBADRPC.

Also it is not fatal if getting current IRQ of boot disabled devices
