42747553f484b2cfcfb919643e1749c9ad782766 21-Apr-2016 pfg <pfg@FreeBSD.org> sys: use our nitems() macro when param.h is available.

This should cover all the remaining cases in the kernel.

4f7fc385cadf246ec334db975b16c0e1743e87da 09-May-2015 bz <bz@FreeBSD.org> Convert remaining hwpmc(4) debug printfs over to KTR to unbreak the build
for at least powerpc kernels. Missed in r282658.

bc81ea301e2e39ee714b97087200dda9cec8f661 05-Apr-2015 adrian <adrian@FreeBSD.org> Add support for the MIPS74K SoC family performance counters events.

These are similar to the mips24k performance counters - some are
available on perfcnt0/3, some are available on perfcnt1/4.
However, the events aren't all the same.

* Add the events, named the same as from Linux oprofile.
* Verify they're the same as "MIPS32(R) 74KTM Processor Core Family
Software User's Manual"; Document Number: MD00519; Revision 01.05.
* Rename INSTRUCTIONS to something else, so it doesn't clash with
the alias INSTRUCTIONS. I'll try to tidy this up later; there
are a few other aliases to add and shuffle around.


* QCA9558 SoC (AP135 board) - MIPS74Kc core (no FPU.)
* make universe; where it didn't fail for other reasons.


* It'd be nice to support the four performance counters
in at least this hardware, rather than just two.
