  "message": "mm: add a basic debugging framework for memory initialisation\n\nBoot initialisation is very complex, with significant numbers of\narchitecture-specific routines, hooks and code ordering.  While significant\namounts of the initialisation is architecture-independent, it trusts the data\nreceived from the architecture layer.  This is a mistake, and has resulted in\na number of difficult-to-diagnose bugs.\n\nThis patchset adds some validation and tracing to memory initialisation.  It\nalso introduces a few basic defensive measures.  The validation code can be\nexplicitly disabled for embedded systems.\n\nThis patch:\n\nAdd additional debugging and verification code for memory initialisation.\n\nOnce enabled, the verification checks are always run and when required\nadditional debugging information may be outputted via a mminit_loglevel\u003d\ncommand-line parameter.\n\nThe verification code is placed in a new file mm/mm_init.c.  Ideally other mm\ninitialisation code will be moved here over time.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
