for a signal, because kernel stack is swappable, this causes page fault
in kernel under heavy swapping case. Fix this bug by eliminating unneeded
code.
Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
IRQs of children. This works similar to e.g. sbus(4), i.e. add the
IRQ resources as fully specified to the resource lists of the children,
allocate them like normal. When establishing the interrupt search the
interrupt maps of the children for a matching INO to determine which
map we need to write the fully specified interrupt number to and to
enable the mapping (before the RID was used to indicate which interrupt
map to use).
- dev/puc/puc.c:
Revert rev. 1.38, with the above change fhc(4) no longer needs special
treatment for allocating IRQs.

vkbd(4) added,
acpi_snc added,
gx(4) removed,
old vinum(4) removed,
libxpg4 removed,
a separate directory for named(8) dynamic zones added,
rm(1) SUSv3 conformance,
strftime(3) GNU extensions added, and
rc.conf(5) variables: tmpmfs_flags and varmfs_flags.
Update release notes:
Fix a typo (s/machine-indepedent/machine-independent/).
modulating the STPCLK# pin based on the duty cycle. Since p4tcc uses the
same mechanism (but internal to the CPU), we triggered a hang on some
systems at low frequencies when both were in use. Now, disable
acpi_throttle when p4tcc is also present.

of the stack instead of using malloc, as it's not needed. Many thanks to
LSI for investigating and fixing these problems.

panic with the NDISulator if you did "ifconfig ndis0 10.0.0.1/24,"
whereas "ifconfig ndis0 10.0.0.1/24 up" worked fine. The double fault
was caused by the ifconfig thread running out of kernel stack space.
(This was partly due to the NDIsulator using a couple of big buffers on
the stack, but even after fixing that the double fault persisted.)
It turns out that ndis_init() is called in both cases, but in the first
case the code path passes through ieee80211_ioctl(), and it turns out
ieee80211_ioctl() consumes a whopping 2400 bytes of stack space.
Apparently, gcc -O2 causes the ieee80211_ioctl_get80211() routine to
be inlined into ieee80211_ioctl(), and for some reason which I do not
fully understand, this causes ieee80211_ioctl() to consume an extra 2K
of stack space.
To prevent this overly agressive optimization, ieee80211_ioctl_get80211()
is now declared with __attribute__ ((noinline)). With this change,
ieee80211_ioctl() now only reserves about 200 bytes of stack instead of 2400.
create kernel threads and call rfork(2) with RFTHREAD flag set in this case,
which puts parent and child into the same threading group. As a result
all threads that belong to the same program end up in the same threading
group.
This is similar to what linuxthreads port does, though in this case we don't
have a luxury of having access to the source code and there is no definite
way to differentiate linux_clone() called for threading purposes from other
uses, so that we have to resort to heuristics.
Allow SIGTHR to be delivered between all processes in the same threading
group previously it has been blocked for s[ug]id processes.
This also should improve locking of the same file descriptor from different
threads in programs running under linux compat layer.

off the heap instead. It's a little slower, but these aren't performance
critical routines.
Also, add a spinlock to NdisAllocatePacketPool(), NdisAllocatePacket(),
NdisFreePacketPool() and NdisFreePacket(). The pool is maintained as a
linked list. I don't know for a fact that it can be corrupted, but why
take chances.
