kernel - zero pages during idle
Bring in base work by Venkatesh Srinivas:
* vm/vm_zeropage.c and bzeront() code.
Plus make the following adjustments:
* Move the bzeront code from platform/ to cpu/ and add a x86_64 version
of bzeront().
* Expose the page zeroing rate via sysctl and adjust the default upwards.
* Expose the movnti feature via sysctl (defaults to off).
* Change poll interval from 1 second to 1/10 second.
* Correct a bug where the MP lock was not being initially released. The
thread is created with the MP lock held. This was causing the hysteresis
check to fail.
* Correct a bug where vm_page_zero_count was being double-incremented
due to changes in how the zerod page is freed.
* Clean up the code syntax a bit.
