[RFC][PATCH 0/20] x86_64: Relocatable bzImage (V3)

Hi All,

Here is the third attempt on implementing relocatable bzImage for x86_64.

Following are the changes since V2.

- Broke suspend/resume code changes into smaller patches. Pavel, I hope
  now it is easier to review.

- Moved cpu long mode and SSE verfication code into a single common 
  file (arch/x86_64/kernel/verify_cpu.S). This file is not shared at all
  the entry places.

- Fixed a bug during resume operation on machines which support NX bit.

Your comments/suggestions are welcome.

Thanks
Vivek
