Partially revert\nthe above git commit and go back to s390 specific page table flush code.\n\nFor s390 the TLB can contain three types of entries, \"normal\" TLB\npage-table entries, TLB combined region-and-segment-table (CRST) entries\nand real-space entries. Linux does not use real-space entries which\nleaves normal TLB entries and CRST entries. The CRST entries are\nintermediate steps in the page-table translation called translation paths.\nFor example a 4K page access in a three-level page table setup will\ncreate two CRST TLB entries and one page-table TLB entry. The advantage\nof that approach is that a page access next to the previous one can reuse\nthe CRST entries and needs just a single read from memory to create the\npage-table TLB entry. The disadvantage is that the TLB flushing rules are\nmore complicated, before any page-table may be freed the TLB needs to be\nflushed.\n\nIn short: the generic RCU page-table freeing code is incorrect for the\nCRST entries, in particular the check for mm_users \u003c 2 is troublesome.\n\nThis is applicable to 3.0+ kernels.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "50483c3268918ee51a56d1baa39b9149d2d0d521", "tree": "2fb9c927c319628ebddfd118c10df3e626bdd1c4", "parents": [ "7fda0412c5f7afdd1a5ff518f98dee5157266d8a", "1631fcea8399da5e80a80084b3b8c5bfd99d21e7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 29 14:49:45 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 29 14:49:45 2012 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile\n\nPull arch/tile (really asm-generic) update from Chris Metcalf:\n \"These are a couple of asm-generic changes that apply to tile.\"\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:\n compat: use sys_sendfile64() implementation for sendfile syscall\n [PATCH v3] ipc: provide generic compat versions of IPC syscalls\n" }, { "commit": "5d3b56f93244dd5f64f60601bf63caf70d693f75", "tree": "5240d27db87472653932473a0bd460f2b060d323", "parents": [ "212188a596d17d519842ef2173150315735b54e1" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Fri Mar 23 11:13:07 2012 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Fri Mar 23 11:13:25 2012 +0100" }, "message": "[S390] register cpu devices for SMP\u003dn\n\nA kernel compiled with SMP\u003dn will not register any cpu devices.\nThe resulting kernel image will not boot with this error message:\n\n kernel BUG at fs/sysfs/group.c:65!\n\nUse GENERIC_CPU_DEVICES\u003dy if SMP\u003dn to get the missing cpu device.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "48b25c43e6eebb6c0edf72935e8720385beca76b", "tree": "d1c774a79ef5a8373b093479c3dabe9bf16aec07", "parents": [ "fde7d9049e55ab85a390be7f415d74c9f62dd0f9" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Thu Mar 15 13:13:38 2012 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Thu Mar 15 13:13:38 2012 -0400" }, "message": "[PATCH v3] ipc: provide generic compat versions of IPC syscalls\n\nWhen using the \"compat\" APIs, architectures will generally want to\nbe able to make direct syscalls to msgsnd(), shmctl(), etc., and\nin the kernel we would want them to be handled directly by\ncompat_sys_xxx() functions, as is true for other compat syscalls.\n\nHowever, for historical reasons, several of the existing compat IPC\nsyscalls do not do this. semctl() expects a pointer to the fourth\nargument, instead of the fourth argument itself. msgsnd(), msgrcv()\nand shmat() expect arguments in different order.\n\nThis change adds an ARCH_WANT_OLD_COMPAT_IPC config option that can be\nset to preserve this behavior for ports that use it (x86, sparc, powerpc,\ns390, and mips).

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state. Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup. Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup. Reading will return the current state.\n\n* Examples of usage :\n\n # mkdir /containers/freezer\n # mount -t cgroup -ofreezer freezer /containers\n # mkdir /containers/0\n # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n # cat /containers/0/freezer.state\n RUNNING\n\nto freeze all tasks in the container :\n\n # echo FROZEN \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n FREEZING\n # cat /containers/0/freezer.state\n FROZEN\n\nto unfreeze all tasks in the container :\n\n # echo RUNNING \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete. In that case we\nreturn EBUSY. This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime. After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read. The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.
