[lkcd-devel] Revamped page command

[Tom M. <tj...@sg...>]

Attached is a patch that reworks the lcrash page command (for the 7.X.X
tree). It adds support for older, SGI Altix dumps and fixes some
problems with current ia64 dumps. I've added a new command line option
(-L) that allows you to display count number of page stucts from a
starting PFN or page struct address. It automatically handles holes in
physical memory, displaying only those page structs that are valid. I
haven't been able to test these changes out on any architecture other
than ia64. Any exposure/testing on other platforms would be appreciated.

Thanks,

Tom
