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.
