number of cards have been discovered to be matching on the strings of
the cis rather than manufacturer/product id for cards we already had a
prod id for. This is a result of getting the list from the NetBSD
driver which also includes the OID for the cards where such a
distinction mattered (since it was tested against the MAC address we
got from the card). Since we do not try to match OIDs, we do not need
the extra entries and they just waste space.
I'm guessing that some of the dlink entires (DE-660, DE-660+) and many
of the corega cards may fall into this boat and can safely be removed.
the per-cpu data for all CPUs. This is easier to ask users to do than
"figure out how many CPUs you have, now run show pcpu, then run it
once for each CPU you have".

the vast majority of cases, these functions are called without mutexes
held, meaning that in all but two cases, there will be no ordering
issues with doing this, and it will eliminate the need for changes in
the caller. In two cases, mutexes are held, so Giant must be acquired
before those mutexes such that uprintf() and tprintf() recurse Giant
rather than generating a lock order reversal.

driver-induced errors, instead be better about propagating error status
upwards. Add more error definitions, courtesy of the linux driver. Fix
a command leak in the ioctl handler. Re-arrange some of the command handlers
to localize error handling.

remove the unconditional acquisition of Giant for extended attribute related
operations. If the file system is set as being MP safe and debug.mpsafevfs is
1, do not pickup Giant.
Mark the following system calls as being MP safe so we no longer pickup Giant
in the system call handler:
o extattrctl
o extattr_set_file
o extattr_get_file
o extattr_delete_file
o extattr_set_fd
o extattr_get_fd
o extattr_delete_fd
o extattr_set_link
o extattr_get_link
o extattr_delete_link
o extattr_list_file
o extattr_list_link
o extattr_list_fd
-Pass MPSAFE flags to namei(9) lookup and introduce vfslocked variable which
will keep track of any Giant acquisitions.
-Wrap any fd operations which manipulate vnodes in VFS_{UN}LOCK_GIANT
-Drop VFS_ASSERT_GIANT into function which operate on vnodes to ensure that
we are sufficiently protected.
I've tested these changes with various TrustedBSD MAC policies which use
extended attribute a lot on SMP and UP systems (thanks to Scott Long for
making some SMP hardware available to me for testing).

of bus tag+handle.
Instead of
bus_space_write_1(sc->tag, sc->handle, ...)
this macros offer
bus_write_1(sc->resource, ...)
The name+argument transformation is constant and the the macros are
generated (by hand) by the script in tools/bus_macro.sh.
The external part is still called 'struct resource' but the contents
is now visible to drivers etc. This makes it part of the device
driver ABI so it not be changed lightly. A comment to this effect
is in place.
The internal part is called 'struct resource_i' and contain its external
counterpart as one field.
Move the bus_space tag+handle into the external struct resource, this
removes the need for device drivers to even know about these fields
in order to use bus_space to access hardware. (More in following commit).
and bus_free_resources(). These functions take a list of resources
and handle them all in one go. A flag makes it possible to mark
a resource as optional.
A typical device driver can save 10-30 lines of code by using these.
Usage examples will follow RSN.

FYI this bit isn't needed for FreeBSD - I think it came from either
OpenBSD or NetBSD where arc4random() wasn't available during cold
boot.
