f159d7d6f0 Only calibrate ICR read loop when not in x2APIC mode. Run-time
switching between LAPIC modes is not supported, and there is no need
to wait for IPI ack in x2APIC mode.  So the calibrated delay is only
needed for !x2APIC.

This saves around a second of boot time on the real hardware for
x2APIC.

06ca64ecf3 Add support for runtime modifiable module parameters in the LinuxKPI.
Linux module parameters have a permissions value. If any write bits
are set we are allowed to modify the module parameter runtime. Reflect
this when creating the static SYSCTL nodes.

84e717c4cf Add support for boolean sysctl's.
Because the size of bool can be implementation defined, make a bool
sysctl handler which handle bools. Userspace sees the bools like
unsigned 8-bit integers. Values are filtered to either 1 or 0 upon
read and write, similar to what a compiler would do.

183d468536 Another round of changes to add compatibility with the older ESHDC variety
of hardware.  Mostly this focuses on the big changes needed for setting the
bus clock, because ESDHC is SDHCI v2.0 and USDHC is 3.0, and the number,
location, and interpretation of clock divisor bits is vastly different
between the two.  This doesn't get the device all the way to functioning
on ESDHC hardware yet, but it's much closer, now getting through all the
card detection and negotiation of capabilties and speed (but it eventually
hangs on what appears to be a missing interrupt).

Another missing chunk of code for handling ESDHC's 32 bit command-and-mode
register using sdhci's pair of 16 bit writes is added.

This also does some leading whitespace cleanups and sorts some softc
struct members by size, and adds some comments (because when do I ever
touch code without adding comments?).

785df0cb3f [bhnd] Integrate bhnd_chipc's BUS_ADD_CHILD() with a child resource mapping table.
This adds support for automatically configuring bhnd_chipc bus children

on Michael Zhilin's chipc resource mapping work.

The bhnd_sprom_chipc driver has been converted to use DEVICE_IDENTIFY()

This should be nearly drop-in compatible with the child device drivers
in D6250.

40cb6df5f3 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.

a66dc0c52b 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.

924b84c108 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.

93ea9f9fa1 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.

1d9b99e5e3 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.

fa201e28fc 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.
