Summary:
If a user uses powerd, or doesn't want to use the cycles monitoring, they can
now suspend the monitoring thread.
While here, reorganize the added prototypes to match existing groupings.

He noticed issues setting this bit in SRRCTL after the queue was up,
so doing it from the sysctl handler isn't enough and may not actually
work correctly.
This commit doesn't remove the sysctl path or try to change its
behaviour. I'll talk with others about how to finish fixing that
before I tackle that.

Without this change the accounting of L2ARC usage would be wrong and
give 16EB free space because the number became negative and overflows.

few changes to drivers, no kernel config was added. As the SoCs are quite
old and the code is unmaintained start the process of removing support by
deleting the header file and code that depends on it along with the macro
SOC_OMAP3. Other Ti SoCs shouldn't be affected, other than for us to have
less code to maintain.

There's a very remote, but possible, chance that the integer part read will
fail, but the fraction read succeeds, at which point the reported temperature is
invalid.

Summary:
Add a polling loop (1Hz) to monitor the battery and AC status, to notify devd
like ACPI does for power monitoring. This allows /etc/rc.d/power_profile to
work on PowerPC laptops
Test Plan:
Tested on a Titanium PowerBook, configuring economy_cpu_freq and
performance_cpu_freq, disabling powerd.

data in an mbuf, use M_WRITABLE() instead of a direct test of M_EXT;
the latter both unnecessarily exposes mbuf-allocator internals in the
protocol stack and is also insufficient to catch all cases of
non-writability.
(NB: m_pullup() does not actually guarantee that a writable mbuf is
returned, so further refinement of all of these code paths continues to
be required.)

in more generic way. Also make it report list of connected initiators in
unified way, working for both FC and iSCSI, and potentially others.

- Add a mutex to protect the softc.
- Use callout(9) instead of timeout(9).
- Consolidate duplicated detach routines into a bus-independent detach
routine.
- Add an extra sleep lock flag (MSESC_READING) to prevent other readers
from reading while the first reader is copying data out of sc_bytes[]
via uiomove().
- Use bus_*() instead of bus_space_*().

1. Remove initializer for badstack_sbuf_size; it gets set unconditionally.
2. Remove meaningless comment.
3. Group witness_count and its sysctl together.
4. Fix spacing in for statements (space after for and within condition).
5. Change *all* M_NOWAIT usages in witness_initialize() to M_WAITOK; not
just those that were newly introduced -- the allocation is assumed to
succeed for all allocations.
6. Avoid using uint8_t as the base type in sizeof() expressions; Use the
variable name (w_rmatrix) as much as possible.
