Re: [Crash-utility] [PATCH} crash 4.0-2.8 fixes to make itworkonx86_64 for 2.6.14

Dave, Here is the latest patch to make crash work on 2.6.14 kernel - with fixes for 4-level pagetables also. I changes & naming are kind of hacky (especially with naming) -- but to cleanup it completely and have backward compatibility needs more work. We should get rid of PML4 completely and move to PGD/PUD/PMD/PTE. Thanks, Badari
