[PATCH 06/10] x86: Change NR_CPUS arrays in topology

[travis@sgi.com]

[-- Attachment #1: NR_CPUS-arrays-in-topology --]
[-- Type: text/plain, Size: 1470 bytes --]

Change the following static arrays sized by NR_CPUS to
per_cpu data variables:

	i386_cpu cpu_devices[NR_CPUS];

(And change the struct name to x86_cpu.)
