4c87bece90 [bhnd] Fix release of uninitialized SPROM shadow in chipc detach.
This was triggering a panic on detach; the SPROM shadow is now
maintained by the bhnd_sprom_chipc driver, and should be removed
from chipc.

09f2468df4 [bhnd] Integrate bhnd_chipc's BUS_ADD_CHILD() with a child resource mapping table.
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.

221ca14ee2 Disable alignment faults on armv6, adjust various alignment-related macros
to match the new state of affairs.  The hardware we support has always been
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.

c5d27b0315 Update to ELF Tool Chain r3477
This fixes a EFI/PE header issue that prevented elfcopy-produced .efi
files from working with Secure Boot:

  Make sure section raw size is always padded to multiple of
  FileAlignment from the optional header, as requested by the PE
  specification. This change should reduce the diff between PE image

8d8c35656e Include machine/acle-compat.h in cdefs.h on arm if the compiler doesn't
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.

95a437124b Fix issues found by Coverity in the rtld-elf.c:gethints().
Check that the dirlist path string specification does not cause
overflow and is fully contained in the hints file.
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
first call.

f98bda461d sed: convert sed to use REG_STARTEND more explicitly.
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.

bcd6e4b333 libc: regexec(3) adjustment.
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.

6427f98e8c Implement Linux module parameters as read-only tunable SYSCTLs.
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.

0d8f1c25a2 Prepare for activation of LinuxKPI module parameters as read-only
tunable SYSCTL's. Linux module parameters are associated with the
module they belong to. FreeBSD does not share this concept of a parent
module. Instead add macros which define the prefix to use for the
module parameters in the LinuxKPI consumers.

While at it convert all "bool" LinuxKPI module parameters to "byte"
type, because we don't have a "bool" type of SYSCTL in FreeBSD.

allocated by fmt_argv().  Wave some const magic on ki_args and
