Eric W. Biederman 5234f5eb04 [PATCH] kexec: x86_64 kexec implementation
This is the x86_64 implementation of machine kexec.  32bit compatibility
support has been implemented, and machine_kexec has been enhanced to not care
about the changing internal kernel paget table structures.

From: Alexander Nyberg <alexn@dsv.su.se>
