MFC r209664:
Add ata(4) ability to limit initial ATA mode for devices via device hints.
After boot this mode can be changed with atacontrol/camcontrol as usual.
It works for both legacy and ATA_CAM wrapper mode.
Enhance config to handle MACHINEs with multiple architectures:
- Passing -m to config will now print the MACHINE and MACHINE_ARCH
given in the passed kernel configuration file and then exit.
- If an option is defined in options.MACHINE with the same name as the
architecture of the kernel being configured, that option will be
considered set. This allows conditional compilation based on CPU
architecture.
o make cmd scoped to the whole do_rules function, since it really is
scoped to the whole fucnion. Making it static was the wrong way to
fix referencing it outside of the block in which it was declared
(and conforms to the style of the rest of the file).
o remove a couple of meaningless blank lines
o properly wrap one line.
Partially MFC 209592:
Add a tdksignal() routine that mirrors pksignal() except that it accepts a
thread instead of a process. As an extension, if a NULL ksiginfo_t is
passed in, setup a ksiginfo_t on the stack similar to psignal(). This
provides semantics matching the new tdsignal() function in 9 while
preserving the existing ABI.
MFC 208507,208556,208621:
Add support for corrected machine check interrupts. CMCI is a new local
APIC interrupt that fires when a threshold of corrected machine check
events is reached. CMCI also includes a count of events when reporting
corrected errors in the bank's status register. Note that individual
banks may or may not support CMCI. If they do, each bank includes its own
threshold register that determines when the interrupt fires. Currently
the code uses a very simple strategy where it doubles the threshold on
each interrupt until it succeeds in throttling the interrupt to occur
only once a minute (this interval can be tuned via sysctl). The threshold
is also adjusted on each hourly poll which will lower the threshold once
events stop occurring.
MFC 208787:
Assert that the thread lock is held in sched_pctcpu() instead of
recursively acquiring it. All of the current callers already hold the

While we indeed can't precisely measure time spent in C1, we can consider
measured interval as upper bound. It should be more precise then just
assuming 1/(2*hz). For idle CPU it should be quite precise, for busy - not
worse then before.
MFC r208946:
New netgraph node ng_patch(4). It performs data modification of packets
passing through. Modifications are restricted to a subset of C language
operations on unsigned integers of 8, 16, 32 or 64 bit size.
These are: set to new value (=), addition (+=), subtraction (-=),
multiplication (*=), division (/=), negation (= -), bitwise AND (&=),
bitwise OR (|=), bitwise eXclusive OR (^=), shift left (<<=),
shift right (>>=). Several operations are all applied to a packet
sequentially in order they were specified by user.

places. While here, remove several unused fields from the XEN-specific

Initializes the ratectl for a node when the state is changed to RUN.

rate was 0 and didn't be initialized.

Merge 209589 from head:
After processing the O_SKIPTO opcode our cmd points to the next rule, and
"match" processing at the end of inner loop would look ahead into the next
rule, which is incorrect. Particularly, in the case when the next rule
started with F_NOT opcode it was skipped blindly.
To fix this, exit the inner loop with the continue operator forcibly and
explicitly.
- Add a utility macro to simplify calculating an aggregate sum from a DPCPU
counter variable.
- Rename the internal for loop iterator to "_i" to avoid potential shadowing of
external variables named "i". The "_" prefix is reserved for infrastructure
type code and is therefore not expected to be used by normal code likely to
call DPCPU_SUM(). [1]
- Change DPCPU_SUM to return the sum rather than calculate and assign it
internally. Usage is now: "sum = DPCPU_SUM(dpcpu_var, member_to_sum);" [2]
- Fix some style nits. [3]

- Rework the underlying ALQ storage to be a circular buffer, which amongst other
things allows variable length messages to be easily supported.
- Extend KPI with alq_writen() and alq_getn() to support variable length
messages, which is enabled at ALQ creation time depending on the arguments
passed to alq_open(). Also add variants of alq_open() and alq_post() that
accept a flags argument. The KPI is still fully backwards compatible and

beginning with the highest available rate. Currently we always use

Implement an optional delay to the ddb reset/reboot command.
This allows textdumps to be run automatically with unattended reboots
after a resonable timeout, while still permitting an administrator to

highly accidental results, and default to 15s in case of problems
parsing the timeout value.
