Subject: [PATCH v2 0/4] add support for gcov format introduced in gcc 4.7

This is an attempt to bring support for modified gcov format in gcc 4.7 to
the kernel. It tries to leverage the existing layout/abstraction, which was
designed keeping in mind that the gcov format could change, but some changes had
to be make. Mostly because the current model does not take into account that
even the core gcov structures, like gcov_info, could change. One part that could
be problematic is the addition of the .init_array section for constructors.

Tested with lcov and seems to be working fine, giving similar results as for the
older format.

v2: Included suggestions/code provided by Peter Oberparleiter. Detailed
    description in patches.

Frantisek Hrbata (4):
  gcov: move gcov structs definitions to a gcc version specific file
  gcov: add support for gcc 4.7 gcov format
  gcov: compile specific gcov implementation based on gcc version
  kernel: add support for init_array constructors
