[klibc] klibc integrated git tree updated to 2.6.21-rc2

[H. Peter Anvin]

Hi all,

I realize I have been a bit MIA lately, but I'm going to try to make 
forward progress again on klibc.  I have pushed the current integrated 
tree up to 2.6.21-rc2; so far, no functional enhancements, but I'm 
looking at the following:

- Mount-by-label/mount-by-uuid.
- Ability to fall back on different roots.
- nfsroot on NFSv4.
- nfsroot over IPv6, as soon as the kernel supports NFS over IPv6.

As always, thoughts are appreciated.
