Thank you folks for all the help. I just reviewed the boot logs for next-20150123 and there still seems to be a related issue. I've been boot testing multi_v7_defconfig+CONFIG_ARM_LPAE=y kernel configurations which still seem broken. For example here are two boots with exynos5250-arndale, one with multi_v7_defconfig+CONFIG_ARM_LPAE=y [1] and the other with multi_v7_defconfig[2]. You can see the kernel configurations with CONFIG_ARM_LPAE=y show the splat: [ 14.605950] ------------[ cut here ]------------ [ 14.609163] WARNING: CPU: 1 PID: 63 at ../mm/mmap.c:2858 exit_mmap+0x1b8/0x224() [ 14.616548] Modules linked in: [ 14.619553] CPU: 1 PID: 63 Comm: init Not tainted 3.19.0-rc5-next-20150123 #1 [ 14.626713] Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [ 14.632830] [] (unwind_backtrace) from [] (show_stack+0x10/0x14) [ 14.640473] [] (show_stack) from [] (dump_stack+0x78/0x94) [ 14.647678] [] (dump_stack) from [] (warn_slowpath_common+0x74/0xb0) [ 14.655744] [] (warn_slowpath_common) from [] (warn_slowpath_null+0x1c/0x24) [ 14.664510] [] (warn_slowpath_null) from [] (exit_mmap+0x1b8/0x224) [ 14.672497] [] (exit_mmap) from [] (mmput+0x40/0xf8) [ 14.679180] [] (mmput) from [] (flush_old_exec+0x328/0x604) [ 14.686471] [] (flush_old_exec) from [] (load_elf_binary+0x26c/0x11f4) [ 14.694715] [] (load_elf_binary) from [] (search_binary_handler+0x98/0x244) [ 14.703395] [] (search_binary_handler) from [] (do_execveat_common+0x4dc/0x5bc) [ 14.712421] [] (do_execveat_common) from [] (do_execve+0x28/0x30) [ 14.720235] [] (do_execve) from [] (ret_fast_syscall+0x0/0x34) [ 14.727782] ---[ end trace 5e3ca48b454c7e0a ]--- [ 14.733758] ------------[ cut here ]------------ Has anyone else tested with CONFIG_ARM_LPAE=y that can confirm my findings? > -- > Regards, > Nishanth Menon > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel [1] http://storage.kernelci.org/next/next-20150123/arm-multi_v7_defconfig+CONFIG_ARM_LPAE=y/lab-tbaker/boot-exynos5250-arndale.html [2] http://storage.kernelci.org/next/next-20150123/arm-multi_v7_defconfig/lab-tbaker/boot-exynos5250-arndale.html Cheers, Tyler -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
