Subject: [PATCH] x86: cpuid.c fix style problems

Impact: cleanup, fix style problems

Fixes style problems:
WARNING: Use #include <linux/uaccess.h> instead of <asm/uaccess.h>
ERROR: "foo * bar" should be "foo *bar"
ERROR: trailing whitespace
WARNING: usage of NR_CPUS is often wrong - consider using cpu_possible(), num_possible_cpus(), for_each_possible_cpu(), etc

total: 2 errors, 2 warnings
