This is a respin of the original page_offset and 64-bit page
table changes with some minor changes and a bug fix:
1) Bob's ACKs for the first 6 patches added.
2) Don't use "UL" postfix for shift counts, there is code that
wants those to be "int", particularly printfs in mm/mm_init.c
that use the "%d" format specifier for SECTIONS_SHIFT.
3) Adjust VA_HOLE defines to match what the new 3-level page
tables can actually provide.

Hi,
Tested on 3 configurations, here is the result. I dont see exit_mmap
warning anynmore.
And I think we need to increase NR_CPUS.
Thanks,
