Thanks, Nico.

Could you please take another peek at patch 05/17 (support 64-bit 
virt_to_phys patching)?  You had reviewed it in an earlier posting, but 
I've had to tweak the code to optimize the compiler generated inline 
expansion code.

Patch 14/17 (accomodate >32-bit addresses for page table base) could use 
some attention as well.  The same goes with 12/17 (define 
ARCH_LOW_ADDRESS_LIMIT for bootmem), if you could.
