Not exactly what we want but avoids the lapic code needing the per cpu structures which aren't set up without SMP support. Consider leaving the percpu structure in, just only support for cpu 0. This fixes trying to boot the X86_LEGACY build on a machine with a local apic.
The Little Kernel Embedded Operating System
The LK kernel is an SMP-aware kernel designed for small systems ported to a variety of platforms and cpu architectures.
It is used in a variety of open source and closed source projects, notably the bootloader for a lot of Android phones of various make.
See https://github.com/littlekernel/lk for the latest version.
For comprehensive documentation, see Index.
