DELAY(1) instead. After wading through old commit logs, I found that the
outb() was added not as part of the test but as an intentional delay. In
fact, according to Shanley's PCI book, the configuration 1 data and address
ports should only be accessed using aligned 32-bit accesses (i.e. inl()
and outl()). Thus, using outb() to just the last byte of the port violates
the PCI spec it would seem. On at least one box doing so broke the probe
for PCI, whereas changing it to a DELAY(1) fixed the probe.

peter and jhb: use __volatile__ to prevent gcc from possibly reordering
code, use a null inline instruction instead of a no-op movl (I would
have done this myself if I knew it was allowed) and combine two register
assignments into a single asm statement.
- if_ndis.c: set the NDIS_STATUS_PENDING flag on all outgoing packets
in ndis_start(), make the resource allocation code a little smarter
about how it selects the altmem range, correct a lock order reversal
in ndis_tick().
vm object hasn't changed, the desired page will be at or near the root
of the vm object's splay tree, making vm_page_lookup() cheap. (The only
lock required for vm_page_lookup() is already held.) If, however, the
vm object has changed and retry was requested, eliminating the generation
check also eliminates a pointless acquisition and release of the page
queues lock.
ndis_var.h
- In kern_ndis.c:ndis_send_packets(), avoid dereferencing NULL pointers
created when the driver's send routine immediately calls the txeof
handler (which releases the packets for us anyway).
- In if_ndis.c:ndis_80211_setstate(), implement WEP support.
case so that if devices need different initialization, we can key off
this in the rc scripts (currently unused). Also update the man page
which is a 100% duplicate of the rc scripts.
if_gre.c rev.1.41-1.49
o Spell output with two ts.
o Remove assigned-to but not used variable.
o fix grammatical error in a diagnostic message.
o u_short -> u_int16_t.
o gi_len is ip_len, so it has to be network byteorder.
if_gre.h rev.1.11-1.13
o prototype must not have variable name.
o u_short -> u_int16_t.
o Spell address with two d's.
ip_gre.c rev.1.22-1.29
o KNF - return is not a function.
o The "osrc" variable in gre_mobile_input() is only ever set but not
referenced; remove it.
o correct (false) assumptions on mbuf chain. not sure if it really helps, but
anyways, it is necessary to perform m_pullup.
o correct arg to m_pullup (need to count IP header size as well).
o remove redundant adjustment of m->m_pkthdr.len.
o clear m_flags just for safety.
o tabify.
o u_short -> u_int16_t.

there is no need turn it off when compiling with -finstrument-functions.
Having -Winline turned off mainly broke checking for bogus inlines in
kernels configured with high resolution profiling, e.g., LINT. Not
turning it off unbreaks the warnings for bogus inlines in istallion.c,
but at least the i386 LINT still builds because istallion.c is compiled
without -Werror due to other bugs in it.
waiting on a locked mutex. This involves passing a struct timespec
from the pthread mutex locking interfaces all the way down to the
function that suspends the thread until the mutex is released.
The timeout is assumed to be an absolute time (i.e. not relative to
the current time).
Also, in _thread_suspend() make the passed in timespec const.
Add new kldstat, kldstat-v and kernel macros. The kldstat macro is
functionally equivalent to the previous implementation, but it looks
prettier and it matches the kldstat-v macro better. kldstat-v gives
output similar to userland kldstat -v (note lacking space), and kernel
loads a new kernel and dump.

- Clear out an_dma_vaddr on free so we can test to see if dma is
setup when the card is kldunloaded/kldloaded etc. only for MPI350
- Use a common detach like wi(4)
- Notify on RID read overflow and truncate this currently causes
a panic in -stable when the stack during an ifconfig an0 is done
with newer firmware
- Convert from UNLOCK/tsleep/LOCK to msleep. I thought I did that
a while ago.
method with something a little more intelligent: use BUS_GET_RESOURCE_LIST()
to run through all resources allocated to us and map them as needed. This
way we know exactly what resources need to be mapped and what their RIDs
are without having to guess. This simplifies both ndis_attach() and
ndis_convert_res(), and eliminates the unfriendly "ndisX: couldn't map
<foo>" messages that are sometimes emitted during driver load.
(msdosfs uses normal 8-char indentation almost everywhere else),
too-long lines, and minor English usage errors. The verbose formal
comment before the new function is still abnormal.
