MIPS: Allow L2 prefetch to be configured via debugfs When debugging or examining the performance of a system it can be useful to examine the effect of L2 prefetching. Provide an optional debugfs entry to allow a user to enable or disable L2 prefetching. Signed-off-by: Paul Burton <[email protected]> Cc: Maciej W.
