  "message": "parisc: fix kernel crash (protection id trap) when compiling ruby1.9\n\nOn Wed, Dec 17, 2008 at 11:46:05PM +0100, Helge Deller wrote:\n\u003e\n\nHonestly, I can\u0027t decide whether to apply this. It really should never\nhappen in the kernel, since the kernel can guarantee it won\u0027t get the\naccess rights failure (highest privilege level, and can set %sr and\n%protid to whatever it wants.)\n\nIt really genuinely is a bug that probably should panic the kernel. The\nonly precedent I can easily see is x86 fixing up a bad iret with a\ngeneral protection fault, which is more or less analogous to code 27\nhere.\n\nOn the other hand, taking the exception on a userspace access really\nisn\u0027t all that critical, and there\u0027s fundamentally little reason for the\nkernel not to SIGSEGV the process, and continue...\n\nArgh.\n\n(btw, I\u0027ve instrumented my do_sys_poll with a pile of assertions that\n %cr8 \u003c\u003c 1 \u003d\u003d %sr3 \u003d\u003d current-\u003emm.context... let\u0027s see if where we\u0027re\n getting corrupted is deterministic, though, I would guess that it won\u0027t\n be.)\n\nSigned-off-by: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\n",
