Kmake

From OMAPpedia

This script does the following:

• builds the kernel prior to the current patch and after the patch and points out
  • build warning deltas
  • size changes
• static checks the impacted files
• checks kernel documentation for the changed files
• header file dependency checks
• git am and checkpatch tests

WARNING: this does not provide any logical/functionality checks and merely uses a series of existing kernel scripts to go through the patch
