Re: [patch] cpu_early_init() breakage

[Mike Galbraith]

Bah, missed quilt refresh after fixing my own typo :)

0388423 typo caused loss of vendor data even with CONFIG_PROCESSOR_SELECT.

[    0.000000] CPU: vendor_id 'GenuineIntel' unknown, using generic init.
[    0.000000] CPU: Your system may be unstable.
[    0.044003] MCE: unknown CPU type - not enabling MCE support.
...
[    0.437241] Brought up 4 CPUs
