Subject: [PATCH 00/23] x86, realmode: new infrastructure for realmode code

I've been working together with H. Peter Anvin in order
replace the ad-hoc real-mode code inside .x86_trampoline
section with an encapsulated binary that is fully relocatable
to any memory location under 1MB. Everything that is needs to
be relocated is relocated during initialization.

Benefits:
- Simplifies things. Real-mode code does not have to find its
own location any more. This makes maintaining and extending 
this code much nicer experience.
- Cleans up code base a lot. Now real-mode code is encapsulated
from kernel both in source tree and in vmlinux.
- We can set proper permissions to pages of text, data/bss
and rodata. Before, .x86_trampoline had just rwx permissions.
