Subject: [PATCH v2 0/2] Fix tracing with non-continuous cpu ids

Currently exception occures due to access beyond buffer_iter
range while using index of cpu bigger than num_possible_cpus().

In order to fix buffer allocation size for non-continuous cpu ids
we allocate according to the max cpu id and not according to the
amount of possible cpus.

This series also includes a checkpatch warning fix for using
kzalloc with multiply instead of kcalloc.

Happy tracing,
Gil

v2:
  Update commit description for patch 1/2.

Gil Fruchter (2):
  tracing: Prefer kcalloc over kzalloc with multiply
  tracing: Fix for non-continuous cpu ids
