There were three calls sites:
- recalculate_apic_map and kvm_apic_match_physical_addr, where it would
only complicate implementation of x2APIC hotplug;
- in apic_debug, where it was still somewhat preserved, but keeping the
old function just for apic_debug was not worth it

Slow path tried to prevent IPIs from x2APIC VCPUs from being delivered
to xAPIC VCPUs and vice-versa. Make slow path behave like fast path,
which never distinguished that.

thanks!

LAPIC after reset is in xAPIC mode, which poses a problem for hotplug of
VCPUs with high APIC ID, because reset VCPU is waiting for INIT/SIPI,
but there is no way to uniquely address it using xAPIC.

This series adds the support for Cavium Cryptographic Accelerarion Unit (CPT)
CPT is available in Cavium's Octeon-Tx SoC series.
The series was tested with ecryptfs and dm-crypt for in kerne

Is that actually true? I thought some arches excluded the kernel image from
the page struct array to make the array consume less memory.
