09a8126 Jarkko Lavinen 01 December 2008, 21:14:08 UTC i82875p_edac: fix module remove Fix module removal bugs of i82875p_edac. Also i82975x_edac code seems to have the same module removal bugs as in i82875p_edac. The problems were: 1. In module removal i82875p_remove_one() is never called. Variable i82875p_registered is newer changed from 1, which guarantees i82875p_remove_one() is not called (and even if it were called, it would be called in wrong order). As a result, the edac_mc workque is not stopped and keeps probing. If kernel debugging options are not enabled, user may not notice anything going wrong. if debugging options are enabled and I do "rmmod i82875p_edac", I get: edac debug: edac_pci_workq_function() checking BUG: unable to handle kernel paging request at f882d16f ... call trace: [<f8834df3>] ? edac_mc_workq_function+0x55/0x7e [edac_core] [<c0233974>] ? run_workqueue+0xd7/0x1a5 [<c023392f>] ? run_workqueue+0x92/0x1a5 [<f8834d9e>] ? edac_mc_workq_function+0x0/0x7e [edac_core] [<c0233af9>] ? worker_thread+0xb7/0xc3 [<c0236a7b>] ? autoremove_wake_function+0x0/0x33 [<c0233a42>] ? worker_thread+0x0/0xc3 [<c0236809>] ? kthread+0x3b/0x61 [<c02367ce>] ? kthread+0x0/0x61 [<c0204587>] ? kernel_thread_helper+0x7/0x10 Fix for this is to get rid of needles variable i82875p_registered altogether and run i82875p_remove_one() *before* pci_unregister_driver(). 2. edac_mc_del_mc() uses mci after freeing mci edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). The kobject refcount of mci drops to 0 and mci is freed. After this mci is accessed via debug print and i82875p_remove_one() still uses mci->pvt and tries to free mci again with edac_mc_free(). The fix for this is add kobject_get(&mci->edac_mci_kobj) after edac_mc_alloc(). Then the mci is still available after returning from edac_mc_del_mc() with refcount 1, and mci->pvt is still available. When i82875p_remove_one() finally calls edac_mc_free(), this will cause kobject_put() and mci is released properly.

307d114 Jarkko Lavinen 01 December 2008, 21:14:06 UTC i82875p_edac: fix overflow device resource setup When I do "modprobe i82875p_edac" on my Asus P4C800 MB on kernels 2.6.26 or later, the module load fails due to BAR 0 collision. On 2.6.25 the module loads just fine. The overflow device on the MB seems to be hidden and its resources are not allocated at normal PCI bus init. Log shows the missing resource problem: EDAC DEBUG: i82875p_probe1() PCI: 0000:00:06.0 reg 10 32bit mmio: [fecf0000, fecf0fff] pci 0000:00:06.0: device not available because of BAR 0 [0xfecf0000-0xfecf0fff] collisions EDAC i82875p: i82875p_setup_overfl_dev(): Failed to enable overflow device The patch below fixes this by calling pci_bus_assign_resources() after the overflow device is revealed and added to the bus. With this patch I am again able to load and use the module.

bca404a Dmitry Baryshkov 01 December 2008, 21:14:05 UTC fbdev: fix FB console blanking The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with recursive locking in fb blanking code if blank is caused by user setting the /sys/class/graphics/fb*/blank. However this broke the fbcon timeout blanking. If you use a driver that defines ->fb_blank operation and at the same time that driver relies on other driver (e.g. backlight or lcd class) to blank the screen, when the fbcon times out and tries to blank the fb, it will call only fb driver blanker and won't notify the other driver. Thus FB output is disabled, but the screen isn't blanked. Restore fbcon blanking and at the same time apply the proper fix for the above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are already called through notification from fb_blank, thus we don't have to blank the fb again.

7ef9964 Davide Libenzi 01 December 2008, 21:13:55 UTC epoll: introduce resource usage limits It has been thought that the per-user file descriptors limit would also limit the resources that a normal user can request via the epoll interface. Vegard Nossum reported a very simple program (a modified version attached) that can make a normal user to request a pretty large amount of kernel memory, well within the its maximum number of fds. To solve such problem, default limits are now imposed, and /proc based configuration has been introduced. A new directory has been created, named /proc/sys/fs/epoll/ and inside there, there are two configuration points: max_user_instances = Maximum number of devices - per user max_user_watches = Maximum number of "watched" fds - per user The current default for "max_user_watches" limits the memory used by epoll to store "watches", to 1/32 of the amount of the low RAM. As example, a 256MB 32bit machine, will have "max_user_watches" set to roughly 90000. That should be enough to not break existing heavy epoll users. The default value for "max_user_instances" is set to 128, that should be enough too. This also changes the userspace, because a new error code can now come out from EPOLL_CTL_ADD (-ENOSPC). The EMFILE from epoll_create() was already listed, so that should be ok.

The PSC controller holds SS low until the flag is set. However, the flag was set always on the last byte of the FIFO, independently if it is the last byte of the transfer.

dc19f9d KAMEZAWA Hiroyuki 01 December 2008, 21:13:48 UTC memcg: memory hotplug fix for notifier callback Fixes for memcg/memory hotplug. While memory hotplug allocate/free memmap, page_cgroup doesn't free page_cgroup at OFFLINE when page_cgroup is allocated via bootomem. (Because freeing bootmem requires special care.) Then, if page_cgroup is allocated by bootmem and memmap is freed/allocated by memory hotplug, page_cgroup->page == page is no longer true. But current MEM_ONLINE handler doesn't check it and update page_cgroup->page if it's not necessary to allocate page_cgroup. (This was not found because memmap is not freed if SPARSEMEM_VMEMMAP is y.) And I noticed that MEM_ONLINE can be called against "part of section". So, freeing page_cgroup at CANCEL_ONLINE will cause trouble. (freeing used page_cgroup) Don't rollback at CANCEL. One more, current memory hotplug notifier is stopped by slub because it sets NOTIFY_STOP_MASK to return vaule. So, page_cgroup's callback never be called. (low priority than slub now.) I think this slub's behavior is not intentional(BUG). and fixes it. Another way to be considered about page_cgroup allocation: - free page_cgroup at OFFLINE even if it's from bootmem and remove specieal handler. But it requires more changes.

b29acbd Nick Piggin 01 December 2008, 21:13:47 UTC mm: vmalloc fix lazy unmapping cache aliasing Jim Radford has reported that the vmap subsystem rewrite was sometimes causing his VIVT ARM system to behave strangely (seemed like going into infinite loops trying to fault in pages to userspace). We determined that the problem was most likely due to a cache aliasing issue. flush_cache_vunmap was only being called at the moment the page tables were to be taken down, however with lazy unmapping, this can happen after the page has subsequently been freed and allocated for something else. The dangling alias may still have dirty data attached to it. The fix for this problem is to do the cache flushing when the caller has called vunmap -- it would be a bug for them to write anything else to the mapping at that point. That appeared to solve Jim's problems.

At first glance, this seems ok but in reality it can happen. My test case was to just run 'exorcist'. A struct inode is being pushed out of memory but is then re-read at a later time, before the buffer has been checkpointed by jbd. This causes a BUG to be hit in ocfs2_read_blocks_sync().

This patch updates piix_broken_suspend() such that it can match such case. As the borked DMI data is a bit generic, matching many entries to make the match more specific is necessary.

42ab01c Jack Morgenstein 01 December 2008, 18:09:37 UTC IB/mlx4: Fix MTT leakage in resize CQ When resizing a CQ, MTTs associated with the old CQE buffer were not freed. As a result, if any app used resize CQ repeatedly, all MTTs were eventually exhausted, which led to all memory registration operations failing until the driver is reloaded. Once the RESIZE_CQ command returns successfully from FW, FW no longer accesses the old CQ buffer, so it is safe to deallocate the MTT entries used by the old CQ buffer. Finally, if the RESIZE_CQ command fails, the MTTs allocated for the new CQEs buffer also need to be de-allocated. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.

ab598b6 Paul Mackerras 30 November 2008, 11:49:45 UTC powerpc: Fix system calls on Cell entered with XER.SO=1 It turns out that on Cell, on a kernel with CONFIG_VIRT_CPU_ACCOUNTING = y, if a program sets the SO (summary overflow) bit in the XER and then does a system call, the SO bit in CR0 will be set on return regardless of whether the system call detected an error. Since CR0.SO is used as the error indication from the system call, this means that all system calls appear to fail. The reason is that the workaround for the timebase bug on Cell uses a compare instruction. With CONFIG_VIRT_CPU_ACCOUNTING = y, the ACCOUNT_CPU_USER_ENTRY macro reads the timebase, so we end up doing a compare instruction, which copies XER.SO to CR0.SO. Since we were doing this in the system call entry patch after clearing CR0.SO but before saving the CR, this meant that the saved CR image had CR0.SO set if XER.SO was set on entry. This fixes it by moving the clearing of CR0.SO to after the ACCOUNT_CPU_USER_ENTRY call in the system call entry path.

cc353c3 Arnd Bergmann 28 November 2008, 09:51:23 UTC powerpc/mpic: Don't reset affinity for secondary MPIC on boot Kexec/kdump currently fails on the IBM QS2x blades when the kexec happens on a CPU other than the initial boot CPU. It turns out that this is the result of mpic_init trying to set affinity of each interrupt vector to the current boot CPU. As far as I can tell, the same problem is likely to exist on any secondary MPIC, because they have to deliver interrupts to the first output all the time. There are two potential solutions for this: either not set up affinity at all for secondary MPICs, or assume that a single CPU output is connected to the upstream interrupt controller and hardcode affinity to that per architecture. This patch implements the second approach, defaulting to the first output. Currently, all known secondary MPICs are routed to their upstream port using the first destination, so we hardcode that.

d015fe9 Arnd Bergmann 28 November 2008, 09:51:22 UTC powerpc/cell/axon-msi: Retry on missing interrupt The MSI capture logic for the axon bridge can sometimes lose interrupts in case of high DMA and interrupt load, when it signals an MSI interrupt to the MPIC interrupt controller while we are already handling another MSI. Each MSI vector gets written into a FIFO buffer in main memory using DMA, and that DMA access is normally flushed by the actual interrupt packet on the IOIF. An MMIO register in the MSIC holds the position of the last entry in the FIFO buffer that was written. However, reading that position does not flush the DMA, so that we can observe stale data in the buffer. In a stress test, we have observed the DMA to arrive up to 14 microseconds after reading the register. This patch works around this problem by retrying the access to the FIFO buffer. We can reliably detect the conditioning by writing an invalid MSI vector into the FIFO buffer after reading from it, assuming that all MSIs we get are valid. After detecting an invalid MSI vector, we udelay(1) in the interrupt cascade for up to 100 times before giving up.

It is caused by commit 8f64e1f2d1e09267ac926e15090fd505c1c0cbcb ("powerpc: Reserve in bootmem lmb reserved regions that cross NUMA nodes"). The problem is that Jon took a loop which was (in pseudocode): for_each_node(nid) NODE_DATA(nid) = careful_alloc(nid); setup_bootmem(nid); reserve_node_bootmem(nid); and broke it up into: for_each_node(nid) NODE_DATA(nid) = careful_alloc(nid); setup_bootmem(nid); for_each_node(nid) reserve_node_bootmem(nid); The issue comes in when the 'careful_alloc()' is called on a node with no memory. It falls back to using bootmem from a previously-initialized node. But, bootmem has not yet been reserved when Jon's patch is applied. It gives back bogus memory (0xc000000000000000) and pukes later in boot. The following patch collapses the loop back together. It also breaks the mark_reserved_regions_for_nid() code out into a function and adds some comments. I think a huge part of introducing this bug is because for loop was too long and hard to read. The actual bug fix here is the: + if (end_pfn <= node->node_start_pfn || + start_pfn >= node_end_pfn) + continue; Signed-off-by: Dave Hansen <dave@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org> 30 November 2008, 22:40:18 UTC
4b824de Adhemerval Zanella 19 November 2008, 03:55:35 UTC powerpc: Fix IRQ assignment for some PCIe devices Currently, some PCIe devices on POWER6 machines do not get interrupts assigned correctly. The problem is that OF doesn't create an "interrupt" property for them. The fix is for of_irq_map_pci to fall back to using the value in the PCI interrupt-pin register in config space, as we do when there is no OF device-tree node for the device. I have verified that this works fine with a pair of Squib-E SAS adapter on a P6-570.
