We need to get the siginfo for each signal on\ncheckpointing dump, and then return it back on restore.\n\nThe first problem is that the kernel doesn\u0027t report complete siginfos to\nuserspace. In a signal handler the kernel strips SI_CODE from siginfo.\nWhen a siginfo is received from signalfd, it has a different format with\nfixed sizes of fields. The interface of signalfd was extended. If a\nsignalfd is created with the flag SFD_RAW, it returns siginfo in a raw\nformat.\n\nrt_sigqueueinfo looks suitable for restoring signals, but it can\u0027t send\nsiginfo with a positive si_code, because these codes are reserved for\nthe kernel. In the real world each person has right to do anything with\nhimself, so I think a process should able to send any siginfo to itself.\n\nThis patch:\n\nThe kernel prevents sending of siginfo with positive si_code, because\nthese codes are reserved for kernel.

you will need to enable memory control groups.\n\n There is a minor bug fix to prevent overflowing the stack if someone\n creates way too many user namespaces.\n\n The bulk of the changes are a continuation of the kuid/kgid push down\n work through the filesystems. These changes make using uids and gids\n typesafe which ensures that these filesystems are safe to use when\n multiple user namespaces are in use. The filesystems converted for\n 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The\n changes for these filesystems were a little more involved so I split\n the changes into smaller hopefully obviously correct changes.\n\n XFS is the only filesystem that remains. I was hoping I could get\n that in this release so that user namespace support would be enabled\n with an allyesconfig or an allmodconfig but it looks like the xfs\n changes need another couple of

When it is waken up, it tries to find another cpu to run, and\nget a -1 nid. As a result, cpumask_of_node(-1) returns NULL, and causes\nernel panic.\n\nThis patch fixes this problem by judging if the nid is -1. If nid is\nnot -1, a cpu on the same node will be picked. Else, a online cpu on\nanother node will be picked.\n\nSigned-off-by: Tang Chen \u003ctangchen@cn.fujitsu.com\u003e\nSigned-off-by: Wen Congyang \u003cwency@cn.fujitsu.com\u003e\nCc: Yasuaki Ishimatsu \u003cisimatu.yasuaki@jp.fujitsu.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Jiang Liu \u003cliuj97@gmail.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: \"H.

interrelated (and concurrently\n developed) changes, which is why the branch history is messier than\n one would like.\n\n The *really* big items are two humonguous patchsets mostly developed\n by Yinghai Lu at my request, which completely revamps the way we\n create initial page tables. In particular, rather than estimating how\n much memory we will need for page tables and then build them into that\n memory -- a calculation that has shown to be incredibly fragile -- we\n now build them (on 64 bits) with the aid of a \"pseudo-linear mode\" --\n a #PF handler which creates temporary page tables on demand.\n\n This has several advantages:\n\n 1. It makes it much easier to support things that need access to data\n very early (a followon patchset uses this to load microcode way\n early in the kernel startup).\n\n 2. It allows the kernel and all the kernel data objects to be invoked\n from above the 4 GB limit. This allows kdump to work on very large\n systems.\n\n 3. It greatly reduces the difference between Xen and native (Xen\u0027s\n equivalent of the #PF handler are the temporary page tables created\n by the domain builder), eliminating a bunch of fragile hooks.\n\n The patch series also gets us a bit closer to W^X.\n\n Additional work in this pull is the 64-bit get_user() work which you\n were also involved with, and a bunch of cleanups/speedups to\n __phys_addr()/__pa().\"\n\n* \u0027x86-mm-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (105 commits)\n x86, mm: Move reserving low memory later in initialization\n x86, doc: Clarify the use of asm(\"%edx\") in uaccess.h\n x86, mm: Redesign get_user with a __builtin_choose_expr hack\n x86: Be consistent with data size in getuser.S\n x86, mm: Use a bitfield to mask nuisance get_user() warnings\n x86/kvm: Fix compile warning in kvm_register_steal_time()\n x86-32: Add support for 64bit get_user()\n x86-32, mm: Remove reference to alloc_remap()\n x86-32, mm: Remove reference to resume_map_numa_kva()\n x86-32, mm: Rip out x86_32 NUMA remapping code\n x86/numa: Use __pa_nodebug() instead\n x86: Don\u0027t panic if can not alloc buffer for swiotlb\n mm: Add alloc_bootmem_low_pages_nopanic()\n x86, 64bit, mm: hibernate use generic mapping_init\n x86, 64bit, mm: Mark data/bss/brk to nx\n x86: Merge early kernel reserve for 32bit and 64bit\n x86: Add Crash kernel low reservation\n x86, kdump: Remove crashkernel range find limit for 64bit\n memblock: Add memblock_mem_size()\n x86, boot: Not need to check setup_header version for setup_data\n ...\n" }, { "commit": "27ea6dfdc23e5e96e324d6cb3488528c14e4a7f7", "tree": "f3a77ed29e1cecd1f401b86384b322f1b005ef0b", "parents": [ "81ec44a6c69342fec1b1140c60a604027e429f69", "cc883afcc02e1c9c8ab64d20f0288355b857f966" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:55:48 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:55:48 2013 -0800" }, "message": "Merge tag \u0027please-pull-misc-3.9\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux\n\nPull misc ia64 bits from Tony Luck.\n\n* tag \u0027please-pull-misc-3.9\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux:\n MAINTAINERS: update SGI \u0026 ia64 Altix stuff\n sysctl: Enable IA64 \"ignore-unaligned-usertrap\" to be used cross-arch\n" }, { "commit": "7c2db36e730ee4facd341679ecb21ee73ba92831", "tree": "75016fba72aaf0581b9263f7fa4c565e6e634f3c", "parents": [ "8b5628ab83b671f96ac9f174c1bd51c92589fc82", "a47a376f1c025e23e836c0376813c0424de665c2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:38:49 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:38:49 2013 -0800" }, "message": "Merge branch \u0027akpm\u0027 (incoming from Andrew)\n\nMerge misc patches from Andrew Morton:\n\n -

So there is around a 7%\nimprovement, and total cpu utilization doesn\u0027t change.\n\nWithout the patch, cfd_data is shared by all CPUs.\ngeneric_smp_call_function_interrupt does read/write cfd_data several times\nwhich will create a lot of cache ping-pong. With the patch, the data\nbecomes per-cpu. The ping-pong is avoided. And from the perf data, this\ndoesn\u0027t make call_single_queue lock contend.\n\nNext step is to remove generic_smp_call_function_interrupt() from arch\ncode.\n\nSigned-off-by: Shaohua Li \u003cshli@fusionio.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "af3b56289be1f65d5c9f28bb1775e01056a5a2de", "tree": "3f3991255ab0c97e387657749a31a7f3b93a586b", "parents": [ "f3d8496e9c841874faf4f2c850d2322453c89e94" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 21 16:42:40 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:22:19 2013 -0800" }, "message": "time: don\u0027t inline EXPORT_SYMBOL functions\n\nHow is the compiler even handling exported functions that are marked\ninline?
