This adds support for automatically configuring bhnd_chipc bus children
with associated resources, using an internal 'hints' table based directly
on Michael Zhilin's chipc resource mapping work.
The bhnd_sprom_chipc driver has been converted to use DEVICE_IDENTIFY()
with the new resource table.
This should be nearly drop-in compatible with the child device drivers
in D6250.

able to do unaligned accesses, we've just never enabled it until now.
This brings FreeBSD into line with all the other major OSes, and should help
with the growing volume of 3rd-party software that assumes unaligned access
will just work on armv6 and armv7.

have ACLE support built in. The ACLE (ARM C Language Extensions) defines
a set of standardized symbols which indicate the architecture version and
features available. ACLE support is built in to modern compilers (both
clang and gcc), but absent from gcc prior to 4.4.
ARM (the company) provides the acle-compat.h header file to define the
right symbols for older versions of gcc. Basically, acle-compat.h does
for arm about the same thing cdefs.h does for freebsd: defines
standardized macros that work no matter which compiler you use. If ARM
hadn't provided this file we would have ended up with a big #ifdef __arm__
section in cdefs.h with our own compatibility shims.
Remove #include <machine/acle-compat.h> from the zillion other places (an
ever-growing list) that it appears. Since style(9) requires sys/types.h
or sys/param.h early in the include list, and both of those lead to
including cdefs.h, only a couple special cases still need to include
acle-compat.h directly.

Check that the dirlist path string specification does not cause

Check that the dirlist string is nul-terminated.
Make 'hdr' static variable, so that hdr.dirlistlen is available when
hints cached value is used on next function calls. Reset hdr.dirlistlen
to zero if error was detected, so that allocations use reasonable size.
Use 'hints', and not 'p' in the body, since p is only initialized on the

Summarizing the findings in the OpenBSD list:
This solves a reproduceable issue with very recent Mesa where REG_NOTBOL
combined with a match at the begin of the string causes our regex library
to treat the word as not begin of word.
Thanks to Martijn van Duren and Ingo Schwarze for taking the time to
solve this in the least invasive way.

Change the behavior of when REG_STARTEND is combined with REG_NOTBOL.
From the original posting[1]:
"Enable the assumption that pmatch[0].rm_so is a continuation offset
to a string and allows us to do a proper assessment of the character
in regards to it's word position ('^' or '\<'), without risking going
into unallocated memory."
This change makes us similar to how glibc handles REG_STARTEND |
REG_NOTBOL, and is closely related to a soon-to-land fix to sed.
Special thanks to Martijn van Duren and Ingo Schwarze for working
out some consistent behaviour.

Bool module parameters are no longer supported, because there is no
equivalent in FreeBSD.
There are two macros available which control the behaviour of the
LinuxKPI module parameters:
- LINUXKPI_PARAM_PARENT allows the consumer to set the SYSCTL parent
where the modules parameters will be created.
- LINUXKPI_PARAM_PREFIX defines a parameter name prefix, which is
added to all created module parameters.

While at it convert all "bool" LinuxKPI module parameters to "byte"

Currently all radiotap structures in ral(4) are packed, but are not
aligned, which causes ral based devices to crash when one does
'ifconfig wlan0 up' for a wlan interface with a ral wlandev on arches
that care about structure alignment (e.g., MIPS).
Adding an aligned attribute helps fix this problem and ral devices
can be properly brought up.

There is no need to to call strdup() on the value returned by fmt().
The latter calls fmt_argv() which always returns a dynamically
allocated string, and calling strdup() on that leaks the memory
allocated by fmt_argv(). Wave some const magic on ki_args and
ki_env to make the direct assignment happy. This requires a tweak
to the asprintf() case to avoid a const vs. non-const mismatch.
