-Subject: Incorrect local array size in activate spu profiling function
-From: Carl Love <carll@us.ibm.com>
-References: 439553 - LTC48925
-
-Updated the patch to address comments by Michael Ellerman.
-Specifically, changed upper limit in for loop to
-ARRAY_SIZE() macro and added a check to make sure the
-number of events specified by the user, which is used as
-the max for indexing various arrays, is no bigger then the
-declared size of the arrays.
-
-The size of the pm_signal_local array should be equal to the
-number of SPUs being configured in the array.  Currently, the
-array is of size 4 (NR_PHYS_CTRS) but being indexed by a for
-loop from 0 to 7 (NUM_SPUS_PER_NODE).
