Units on machines implementing the Broadband Processor
Architecture.

# we depend on PPC_MM_SLICES for now rather than selecting
# it because we depend on hugetlbfs hooks being present. We
# will fix that when the generic code has been improved to

select PPC_HAS_HASH_64K
help
This option causes SPE local stores to be mapped in process
address spaces using 64K pages while the rest of the kernel
uses 4K pages. This can improve performances of applications
using multiple SPEs by lowering the TLB pressure on them.

This adds the cpufreq driver for Cell BE processors.
For details, take a look at <file:Documentation/cpu-freq/>.
If you don't have such processor, say N
