7 title: Intel Local Advanced Programmable Interrupt Controller (LAPIC)
10   - Rahul Tanwar <rtanwar@maxlinear.com>
15   architecture design, with a local component (LAPIC) integrated
17   (lapic) receives interrupts from the processor's interrupt pins,
22   Many of the Intel's generic devices like hpet, ioapic, lapic have
23   the ce4100 name in their compatible property names because they
24   first appeared in CE4100 SoC.
