* ACPI: disable lower idle C-states across suspend/resumeThomas Gleixner2007-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | device_suspend() calls ACPI suspend functions, which seems to have undesired side effects on lower idle C-states. It took me some time to realize that especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one) show this effect. I'm quite sure that other bug reports against suspend/resume about turning the system into a brick have the same root cause. After fishing in the dark for quite some time, I realized that removing the ACPI processor module before suspend (this removes the lower C-state functionality) made the problem disappear. Interestingly enough the propability of having a bricked box is influenced by various factors (interrupts, size of the ram image, ...). Even adding a bunch of printks in the wrong places made the problem go away. The previous periodic tick implementation simply pampered over the problem, which explains why the dyntick / clockevents changes made this more prominent. We avoid complex functionality during the boot process and we have to do the same during suspend/resume. It is a similar scenario and equaly fragile. Add suspend / resume functions to the ACPI processor code and disable the lower idle C-states across suspend/resume. Fall back to the default idle implementation (halt) instead.

* Revert "x86_64: Quicklist support for x86_64"Linus Torvalds2007-09-21
| | | | | | | | | | | | | | | | | This reverts commit 34feb2c83beb3bdf13535a36770f7e50b47ef299. Suresh Siddha points out that this one breaks the fundamental requirement that you cannot free page table pages before the TLB caches are flushed. The quicklists do not give the same kinds of guarantees that the mmu_gather structure does, at least not in NUMA configurations.

* signalfd simplificationDavide Libenzi2007-09-20
| | | | | | | | | | | | | | | | | | | | This simplifies signalfd code, by avoiding it to remain attached to the sighand during its lifetime. In this way, the signalfd remain attached to the sighand only during poll(2) (and select and epoll) and read(2). This also allows to remove all the custom "tsk == current" checks in kernel/signal.c, since dequeue_signal() will only be called by "current". I think this is also what Ben was suggesting time ago. The external effect of this, is that a thread can extract only its own private signals and the group ones. I think this is an acceptable behaviour, in that those are the signals the thread would be able to fetch w/out signalfd.

* | Fix NUMA Memory Policy Reference CountingLee Schermerhorn2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch proposes fixes to the reference counting of memory policy in the page allocation paths and in show_numa_map(). Extracted from my "Memory Policy Cleanups and Enhancements" series as stand-alone. Shared policy lookup [shmem] has always added a reference to the policy, but this was never unrefed after page allocation or after formatting the numa map data. Default system policy should not require additional ref counting, nor should the current task's task policy. However, show_numa_map() calls get_vma_policy() to examine what may be [likely is] another task's policy. The latter case needs protection against freeing of the policy. This patch adds a reference count to a mempolicy returned by get_vma_policy() when the policy is a vma policy or another task's mempolicy. Again, shared policy is already reference counted on lookup. A matching "unref" [__mpol_free()] is performed in alloc_page_vma() for shared and vma policies, and in show_numa_map() for shared and another task's mempolicy. We can call __mpol_free() directly, saving an admittedly inexpensive inline NULL test, because we know we have a non-NULL policy. Handling policy ref counts for hugepages is a bit trickier. huge_zonelist() returns a zone list that might come from a shared or vma 'BIND policy. In this case, we should hold the reference until after the huge page allocation in dequeue_hugepage(). The patch modifies huge_zonelist() to return a pointer to the mempolicy if it needs to be unref'd after allocation.

* | Fix user namespace exiting OOPsPavel Emelyanov2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turned out, that the user namespace is released during the do_exit() in exit_task_namespaces(), but the struct user_struct is released only during the put_task_struct(), i.e. MUCH later. On debug kernels with poisoned slabs this will cause the oops in uid_hash_remove() because the head of the chain, which resides inside the struct user_namespace, will be already freed and poisoned. Since the uid hash itself is required only when someone can search it, i.e. when the namespace is alive, we can safely unhash all the user_struct-s from it during the namespace exiting. The subsequent free_uid() will complete the user_struct destruction. For example simple program #include <sched.h> char stack[2 * 1024 * 1024]; int f(void *foo) { return 0; } int main(void) { clone(f, stack + 1 * 1024 * 1024, 0x10000000, 0); return 0; } run on kernel with CONFIG_USER_NS turned on will oops the kernel immediately.

| * [SPARC64]: Fix lockdep, particularly on SMP.David S. Miller2007-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the sctp_sockaddr_entry is now RCU enabled as part of the patch to synchronize sctp_localaddr_list, it makes sense to change all handling of these entries to RCU. This includes the sctp_bind_addrs structure and it's list of bound addresses. This list is currently protected by an external rw_lock and that looks like an overkill. There are only 2 writers to the list: bind()/bindx() calls, and BH processing of ASCONF-ACK chunks. These are already seriealized via the socket lock, so they will not step on each other. These are also relatively rare, so we should be good with RCU. The readers are varied and they are easily converted to RCU. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Paul E.
