  "message": "[kernel][arm64][mmu] Fix bug where privileged executable pages are executable from EL0\n\nPreviously, was always setting UXN and PXN bits on pages explicitly\nmapped as non executable, not taking into account that user (EL0) code\ncould access a privileged page because UXN wasn\u0027t set.\n\nChange the logic to appropriately set PXN and UXN bits on user and\nprivleged executable pages, appropriately:\n\nuser/privileged non-executable page: UXN\u003d1, PXN\u003d1\nuser executable page: UXN\u003d0, PXN\u003d1\nprivileged executable page: UXN\u003d1, PXN\u003d0\n\nEL2 mappings for the kernel interpret these bits slightly differently,\nso simply map the non executable code as XN\u003d1 (bit 54).\n\nAdd kernel unit test to validate that pages mapped this way at least\nappear to be in sync with the aspace.Query() api.\n\nBug: 88451\nChange-Id: Icea7a3c5b5effa8b8fe828b3ed6d8e27433caaf0\nReviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/614141\nReviewed-by: Marco Vanotti \u003cmvanotti@google.com\u003e\nCommit-Queue: Travis Geiselbrecht \u003ctravisg@google.com\u003e\n",
