X2APIC support is in master; further testing is needed

[Sepherosa Ziehau]

Hi all,

X2APIC support is in master now.  Please help testing it by adding the
following line to /boot/loader.conf or set it at boot prompt:
hw.x2apic_enable=1

You can check whether it is on or not by:
sysctl hw.x2apic_enable

X2APIC mode will be enabled only if the following command has output
(should be available on modern Intel CPUs):
dmesg | grep x2APIC

It should be safe to test.  I have run with it on my testing machines.

I'd like to thank ivadasz@ for his initial work.

Thanks,
sephe
