667ad4f701 [CPUFREQ] Crusoe: longrun cpufreq module reports false min freq 
The longrun cpufreq module reports a false minimum frequency 3MHz on
300-600MHz Crusoe processor.  This may be due to a calculation bug
in the module.

Original patch from Kaz Sasayama <kazssym@hypercore.co.jp>
submitted as http://bugs.debian.org/468149 patch ported to x86

92cb7612ae x86: convert cpuinfo_x86 array to a per_cpu array 
cpu_data is currently an array defined using NR_CPUS.  This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.

These changes were adopted from the sparc64 (and ia64) code.  An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index.  This corresponds to the index into a cpumask_t as well as the
per_cpu index.  It's used in various places like show_cpuinfo().

cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.
