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.

Thanks
