Be a bit more strict about what is accepted into mainline by building with -Werror set for gcc builds. Clang builds will get the same treatment soon. Also turn off some ubsan compiles for some of the older arches where there's very little value (and it probably doesn't work anyway).
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.
