8054d7cc0d Extend TPS65217 support to be able to pull and decode battery
charger configuration and provide some basic control knobs to
set charger voltage and dump config on boot. Two loader tunables
have been added:

 o hw.am335x_pmic.bootverbose set to 1 to get more info on the
   boot;

 o hw.am335x_pmic.vo: set to charger voltage to be applied on
   kernel initialization time, supported values are "4.10V",
   "4.15V", "4.20V" and "4.25V".

Cleanup code a bit in general, move TPS65217 register
definitions into a separate header, convert bit-banging
defines into bitmap structures.

Also threat the case when power source is neither "AC" nor "USB"
as "Battery", not "Unknown".

b5c5032066 Switch from make_dev_alias to make_dev_alias_p since make_dev_alias_p can
gracefully fail if the /dev/megaraid_sas_ioctl_node symlink already exists.
This can happen if mfi(4) and mrsas(4) are both attached to cards and
providing Linux emulation support.  Let the first one win.  An equivalent
change needs to be done to mrsas(4).  Extra credit would be to pass the
Linux emulation call to the other driver when appropriate.  This will
probably be a rare case and the user can manually change where the symlink
points to.

2c6946dca2 When updating/accessing the timehands, barriers are needed to ensure
that:
- th_generation update is visible after the parameters update is
  visible;
- the read of parameters is not reordered before initial read of
  th_generation.

On UP kernels, compiler barriers are enough.  For SMP machines, CPU
barriers must be used too, as was confirmed by submitter by testing on
the Freescale T4240 platform with 24 PowerPC processors.

125954c873 Handle X2APIC entries in the MADT for APICs with an ID < 255. At least one
BIOS has been seen to include such entries even though the relevant specs
require that X2APIC entries only be used for CPUs with an APIC ID >= 255.

This was tested on a system with "plain" local APIC entries in the MADT
to ensure no regressions, but it has not yet been tested on a system with
X2APIC entries in the MADT.  Currently such systems do not boot at all,
and with this change they might now boot correctly.

90acdcbc88 Merge r283870 from amd64:
Remove unneeded NULL checks in trap_fatal().

Since td_name is an array member of struct thread, it can never be NULL,
so the check can be removed.  In addition, curproc can never be NULL,
so remove the if statement, and splice the two printfs() together.

While here, remove the u_long cast, and use the correct printf format
specifier for curproc->p_pid.

529b5c137e Move contrib/top/top.X to contrib/top/top.xs and move
contrib/top/top.local.H to contrib/top/top.local.hs.
This fixes a build breakage when src is on a case-
insensitive file system -- we never properly create
top.x nor top.local.h. Change the makefile accordingly.

183714f3f7 It has been long time that when doing 'ls -G /path/to/a/symlink', instead of
using the color of symbolic link, the color is determined by the link target.
This behavior was quite confusing.

Looking at the file history, it looks like that r203665 intends to fix this
but the issue was never actually fixed.

Fix this by not setting FTS_COMFOLLOW when color is requested like what was
done in r203665.

f7f155fa58 Break out the current 802.11 software scan methods into an indirect table.
In order for drivers to provide an alternate set of scan methods,
these have to finally use an indirection table and all of the calls
in ieee80211_scan.c need to use said table.

For all existing drivers - this is basically a glorified, KBI-breaking
functional no-op.

This is also not the final form - too much functionality is currently
hiding in ieee80211_scan_sw.c that should be in ieee80211_scan.c.
That'll be the target of some follow-up commits.

Note:

* You have to recompile your kernel/drivers after this - the net80211 KBI has
  changed.
* I'm not yet planning on bumping any versioning - I have a few more things
  to shuffle around.

Tested:

* urtwn(4) - STA mode
* Intel 7260 in local repo - overriding the methods and table at
  attach time has the desired effect (ie, all the methods are called,
  but nothing is ever performed.)

8b84d791a0 witness: don't warn about matrix inconsistencies without holding the mutex
Lock order checking is done without the witness mutex held, so multiple
threads that are racing to establish a new lock order may read matrix
entries that are in an inconsistent state. Don't print a warning in this
case, but instead just redo the check after taking the witness lock.
