*	Add TSC synchronization for multiprocessor machines.	pirofti	2019-08-09	1	-1/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	CPU0 is the reference clock and all others are skewed. During CPU initialization the clocks synchronize by keeping a registry of each CPU clock skewness and adapting the TSC read routine accordingly. This commit also re-enables TSC as the default time source. Future work includes MSR-based synchronization via IA32_TSC_ADJUST and perhaps adding a task that is executed periodically to keep the clocks in sync in case they drift apart. Inspired from NetBSD. Tested by many and thoroughly reviewed by kettenis@, thank you! OK kettenis@, deraadt@
*	Recalibrate TSC timecounter with HPET and PM timer	mikeb	2017-10-06	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	If frequency of an invariant (non-stop) time stamp counter is measured using an independent working timecounter that has a known frequency, we can assume that the measured TSC frequency is as good as the resolution of the timecounter that we use to perform the measurement. This lets us switch from this high quality but expensive source to the cheaper TSC without sacrificing precision on a wide range of modern CPUs. From Adam Steen <adam@adamsteen.com.au> with tweaks from reyk@ and myself. Tested by brynet@, sthen@ and others, OK mlarkin, sthen

*	Add support for x2apic mode	sf	2015-04-19	1	-2/+4
\| \| \| \| \| \| \| \| \|	This is currently only enabled on hypervisors because on real hardware, it requires interrupt remapping which we don't support yet. But on virtualization it reduces the number of vmexits required per IPI from 4 to 1, causing a significant speed-up for MP guests. ok kettenis@

*	First pass at removing clauses 3 and 4 from NetBSD licenses.	ray	2008-06-26	1	-8/+1
\| \| \| \| \| \| \| \| \|	Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

	hacked by art@ from netbsd sources and then later debugged by me into the shape where it can host itself. no bootloader yet as needs redoing from the recent advanced i386 sources (anyone? ;)
