2008-12-10oprofile: set values to default when creating oprofilefsRobert Richter
This patch restores default values for: /dev/oprofile/cpu_buffer_size /dev/oprofile/buffer_watershed /dev/oprofile/buffer_size when creating the oprofilefs: # opcontrol --deinit # opcontrol --init # cat /dev/oprofile/cpu_buffer_size 8192 # echo 5123 > /dev/oprofile/cpu_buffer_size # cat /dev/oprofile/cpu_buffer_size 5123 # opcontrol --deinit # opcontrol --init # cat /dev/oprofile/cpu_buffer_size 8192 # opcontrol --deinit This sets the values in a defined state.

2008-12-01i82875p_edac: fix module removeJarkko Lavinen
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.

2008-12-01i82875p_edac: fix overflow device resource setupJarkko Lavinen
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.

2008-12-01fbdev: fix FB console blankingDmitry Baryshkov
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.

2008-12-01epoll: introduce resource usage limitsDavide Libenzi
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.

However, the flag was set always on the last byte of the FIFO, independently if it is the last byte of the transfer. This generates spurious toggling of the SS signals that breaks the protocol of some peripherals. Fix.

2008-12-01memcg: memory hotplug fix for notifier callbackKAMEZAWA Hiroyuki
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.

2008-12-01mm: vmalloc fix lazy unmapping cache aliasingNick Piggin
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.

2008-12-01ocfs2: fix regression in ocfs2_read_blocks_sync()Mark Fasheh
We're panicing in ocfs2_read_blocks_sync() if a jbd-managed buffer is seen. 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().

2008-12-01ocfs2: fix return value set in init_dlmfs_fs()Coly Li
In init_dlmfs_fs(), if calling kmem_cache_create() failed, the code will use return value from calling bdi_init(). The correct behavior should be set status as -ENOMEM before going to "bail:".

commit 50f3beb50abe0cc0228363af804e50e710b3e5b0 fixed em28xx-alsa locking schema. However, a backport macro was kept. This patch removes the macro, since it is not needed for the module compilation against upstream. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-01libata: blacklist Seagate drives which time out FLUSH_CACHE when used with NCQTejun Heo
Some recent Seagate harddrives have firmware bug which causes FLUSH CACHE to timeout under certain circumstances if NCQ is being used. This can be worked around by disabling NCQ and fixed by updating the firmware. Implement ATA_HORKAGE_FIRMWARE_UPDATE and blacklist these devices. The wiki page has been updated to contain information on this issue. http://ata.wiki.kernel.org/index.php/Known_issues Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-12-01[libata] pata_rb532_cf: fix signature of the xfer functionPhil Sutter

2008-12-01[libata] pata_rb532_cf: fix and rename register definitionsPhil Sutter
The original standalone driver uses a custom address for the error register. Use it in pata_rb532_cf, too. Rename two register definitions: - The address offset 0x0800 in fact is the ATA base, not ATA command address. - The offset 0x0C00 is not a regular ATA data address, but a buffered one allowing 4-byte IO.
