A path toward removal of kernel high-memory support

Description:
As a followup to his OSS Europe talk on the
future of 32-bit support in the kernel , Arnd Bergmann has put together a
detailed plan for the eventual removal of high-memory support, which he
calls " one of the least popular features of the Linux kernel ".  The
intent is " to gradually phase out highmem over the next 2 years for
mainline kernels ".  This plan is posted as a prompt for a discussion to
be held at the Kernel Summit in December, so chances are it will evolve
considerably in the next few months.
