  "message": "nommu: add support for Memory Protection Units (MPU)\n\nSome architectures (like the Blackfin arch) implement some of the\n\"simpler\" features that one would expect out of a MMU such as memory\nprotection.\n\nIn our case, we actually get read/write/exec protection down to the page\nboundary so processes can\u0027t stomp on each other let alone the kernel.\n\nThere is a performance decrease (which depends greatly on the workload)\nhowever as the hardware/software interaction was not optimized at design\ntime.\n\nSigned-off-by: Bernd Schmidt \u003cbernds_cb1@t-online.de\u003e\nSigned-off-by: Bryan Wu \u003ccooloney@kernel.org\u003e\nSigned-off-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Greg Ungerer \u003cgerg@snapgear.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
