Since the\nvectors page is required for handling faults, clearing the YOUNG bit (and\nsubsequently writing a faulting pte) means that we lose the vectors page\n*globally* and cannot fault it back in. This results in a system deadlock\non the next exception.\n\nTo see this problem in action, just run:\n\n\t$ echo 1 \u003e /proc/self/clear_refs\n\non an ARM platform (as any user) and watch your system hang. I think this\nhas been the case since 2.6.37\n\nThis patch avoids clearing the aforementioned bits for reserved pages,\ntherefore leaving the vectors page intact on ARM. Since reserved pages\nare not candidates for swap, this change should not have any impact on the\nusefulness of clear_refs.\n\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\nReported-by:

doesn\u0027t match the permission checking of any of the\nother related files.\n\nThis changes it to do the permission checks at open time, and instead of\ntracking the process, it tracks the VM at the time of the open.

So this patch creates a bare-bones framework which\n will henceforth allow me to ask people to include their test apps in\n the kernel tree so we can keep them alive. Then when people enhance\n or fix the feature, I can ask them to update the test app too.\n\n The infrastruture is terribly trivial at present - let\u0027s see how it\n evolves.\n\n - checkpoint/restart feature work.\n\n A note on this: this is a project by various mad Russians to perform\n c/r mainly from userspace, with various oddball helper code added\n into the kernel where the need is demonstrated.\n\n So rather than some large central lump of code, what we have is\n little bits and pieces popping up in various places which either\n expose something new or which permit something which is normally\n kernel-private to be modified.\n\n The overall project is an ongoing thing. I\u0027ve judged that the size\n and scope of the thing means that we\u0027re more likely to be successful\n with it if we integrate the support into mainline piecemeal rather\n than allowing it all to develop out-of-tree.\n\n However I\u0027m less confident than the developers that it will all\n eventually work!

So if it all\n eventually comes to tears and the project as a whole fails, it should\n be a simple matter to go through and delete all trace of it.\n\nThis lot pretty much wraps up the -rc1 merge for me.\n\n* akpm: (96 commits)\n unlzo: fix input buffer free\n ramoops: update parameters only after successful init\n ramoops: fix use of rounddown_pow_of_two()\n c/r: prctl: add PR_SET_MM codes to set up mm_struct entries\n c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4\n c/r: introduce CHECKPOINT_RESTORE symbol\n selftests: new x86 breakpoints selftest\n selftests: new very basic kernel selftests directory\n radix_tree: take radix_tree_path off stack\n radix_tree: remove radix_tree_indirect_to_ptr()\n dio: optimize cache misses in the submission path\n vfs: cache request_queue in struct block_device\n fs/direct-io.c: calculate fs_count correctly in get_more_blocks()\n drivers/parport/parport_pc.c: fix warnings\n panic: don\u0027t print redundant backtraces on oops\n sysctl: add the kernel.ns_last_pid control\n kdump: add udev events for memory online/offline\n include/linux/crash_dump.h needs elf.h\n kdump: fix crash_kexec()/smp_send_stop() race in panic()\n kdump: crashk_res init check for /sys/kernel/kexec_crash_size\n ...\n" }, { "commit": "b3f7f573a20081910e34e99cbc91831f4f02f1ff", "tree": "2c0aea64b3be4c24f84be6a5275f7202e0dde594", "parents": [ "067bce1a06c1f84146f873a598cd7c3a28eee1d5" ], "author": { "name": "Cyrill Gorcunov", "email": "gorcunov@openvz.org", "time": "Thu Jan 12 17:20:53 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 12 20:13:13 2012 -0800" }, "message": "c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4\n\nThe mm-\u003estart_code/end_code, mm-\u003estart_data/end_data, mm-\u003estart_brk are\ninvolved into calculation of program text/data segment sizes (which might\nbe seen in /proc/\u003cpid\u003e/statm) and into brk() call final address.\n\nFor restore we need to know all these values.
