This patchset implements support for performing kernel code coverage
measurements based on gcc's gcov mechanism. It can be used to improve
kernel code quality by identifying code parts which are not exercised
during test cases. Patch base is 2.6.30-rc7.
Changes since last version:
* removed __gcov_execve (assuming no kernel function will be called
execve)
Patch overview:
[PATCH 1/4] kernel: constructor support
[PATCH 2/4] seq_file: add function to write binary data
[PATCH 3/4] gcov: add gcov profiling infrastructure
[PATCH 4/4] gcov: enable GCOV_PROFILE_ALL for x86_64
