Subject: [PATCH] Section mismatch: acpi_early_processor_set_pdc()

Hi all,

kernel-2.6.33-rc4, compiler output:

WARNING: Section mismatch in reference from the function 
acpi_early_processor_set_pdc() to the variable .cpuinit.data:processor_idle_dmi_table                                                                                           
The function acpi_early_processor_set_pdc() references                                                                            
the variable __cpuinitdata processor_idle_dmi_table.                                                                              
This is often because acpi_early_processor_set_pdc lacks a __cpuinitdata                                                          
annotation or the annotation of processor_idle_dmi_table is wrong.   

acpi_early_processor_set_pdc() is invoked only from __init acpi_bus_init()  
Mark it __cpuinit.

The patch is against 2.6.33-rc4
