Adapted a patch set created by Badari Pulavarty of IBM, that addresses a fatal initialization-time crash error that indicated "crash: invalid structure member offset: x8664_pda_level4_pgt" when run against post-2.6.10 x86_64 kernels. But more importantly, Badari's patch adds support for these x86_64 kernel changes that were introduced in 2.6.11: - x86_64 kernel virtual address range changes, and - x86_64 user virtual address space usage of 4-level page tables
