Fixing x86-64 numa in 2.6.10rc1

Hallo,

As some people already noticed 2.6.10rc1 unfortunately has broken NUMA support on x86-64. The problem is a fallout from the recent nodemask changes, which didn't really work well.

The following four patches fix the known problems.

Linus, please apply them.

Anybody who uses a multi CPU Opteron system with 2.6.10rc1 should apply them too or disable CONFIG_NUMA.
