kernel-mc README
--------------------------------------------------------------------------
This patchset is Horst Burkhardt's "mc" patchset.
It is also the upstream for Adelie Linux' "easy-kernel".
This patchset is designed for compatibility with all distributions, and
is tuned for performance and memory consumption on all architectures.
It integrates some of the patches from Gentoo Linux' "gentoo-sources" to
leverage the bug-finding power of the Gentoo community.
Unless otherwise explicitly stated, the resulting kernel should be
considered to be suitable under all loads and in all environments.
