parent rather than track resources locally. The original code
was incomplete in that it would only honor requests for resources
that already exist in its resource list. This prevented many ISA
identify routines from allocating temporary resources. Passing
the requests up to legacy's parent losing no functionality and
allows these requests to succeed.

have been rush hour...
While here, move COMPAT_IA32 from opt_global.h to opt_compat.h like on
amd64. Consequently, it's unsafe to use the option in pcb.h. We now
unconditionally have the ia32 specific registers in the PCB.
This commit is untested.
This was tested with a Netgear WG311v2 802.11b/g PCI card. Things
that were fixed:
- This chip has two memory mapped regions, one at PCIR_BAR(0) and the
other at PCIR_BAR(1). This is a little different from the other
chips I've seen with two PCI shared memory regions, since they tend
to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly
for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem
first and ndis_res_altmem second, if a second shared memory range
exists. Given that NDIS drivers seem to scan for BARs in ascending
order, I think this should be ok.
- Fixed the code that tries to process firmware images that have been
loaded as .ko files. To save a step, I was setting up the address
mapping in ndis_open_file(), but ndis_map_file() flags pre-existing
mappings as an error (to avoid duplicate mappings). Changed this so
that the mapping is now donw in ndis_map_file() as expected.
- Made the typedef for 'driver_entry' explicitly include __stdcall
to silence gcc warning in ndis_load_driver().
NOTE: the Texas Instruments ACX111 driver needs firmware. With my
card, there were 3 .bin files shipped with the driver. You must
either put these files in /compat/ndis or convert them with
ndiscvt -f and kldload them so the driver can use them. Without
the firmware image, the NIC won't work.
- Trailing tab/space cleanup
- Remove spurious spaces between or before tabs
This change avoids touching files that Andre likely has in his working
set for PFIL hooks changes for IPFW/DUMMYNET.

prodstr may be NULL when fetched. For the default device description,
guard against this and return the numeric IDs instead when this
happens. For the matching routines, and consider NULL to not match
those entries that aren't NULL w/o calling strcmp.

and can lead to two threads being granted exclusive access. Check that no one
has the same lock in exclusive mode before proceeding to acquire it.
The LK_WANT_EXCL and LK_WANT_UPGRADE bits act as mini-locks and can block
other threads. Normally this is not a problem since the mini locks are
upgraded to full locks and the release of the locks will unblock the other
threads. However if a thread reset the bits without obtaining a full lock
other threads are not awoken. Add missing wakeups for these cases.
