I get a compilation error with an undefined reference to PKMAP_BASE (on a fairly standard x86 box). This patch include asm/highmem.h, where the macro is defined. Please apply.

Hi Andrew, This series of patches lays the basic ground work for the paravirtualized kernel patches coming later on. I think this lot is ready for the rough-and-tumble world of the -mm tree. The main change from the last posting is that all the page-table related patches have been moved out, and will be posted separately. Also, the off-by-one in reserving the top of address space has been
