The patch titled acpi_processor_ppc_notifier(): correct bound checking from the value returned from _PPC method has been added to the -mm tree. Its filename is correct-bound-checking-from-the-value-returned-from-_ppc-method.patch See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this ------------------------------------------------------ Subject: acpi_processor_ppc_notifier(): correct bound checking from the value returned from _PPC method From: Dave Jones <davej@xxxxxxxxxx> processor_perflib.c::acpi_processor_ppc_notifier() check if the value returned by the processor's _PPC method is 0 and return failed if so. This is wrong since 0 indicate that the bios think the processor can go to the highest frequency. This patch for example fix the HP NX 6125 to allow its highest frequency to be available.
