commit 24b8256a upstream. When booted in legacy mode device_init_wakeup() gets called by drivers/mfd/twl-core.c when the children are initialized. However, when booted using device tree, the children are created with of_platform_populate() instead add_children(). This means that the RTC driver will not have device_init_wakeup() set, and we need to call it from the driver probe like RTC drivers typically do. Without this we cannot test PM wake-up events on omaps for cases where there may not be any physical wake-up event. Signed-off-by:

commit 39be95e9 upstream. Ceph's encode_caps_cb() worked hard to not call __page_cache_alloc() while holding a lock, but it's spoiled because ceph_pagelist_addpage() always calls kmap(), which might sleep.

commit c420276a upstream. In his review, Alex Elder mentioned that he hadn't checked that num_fcntl_locks and num_flock_locks were properly decoded on the server side, from a le32 over-the-wire type to a cpu type. I checked, and AFAICS it is done; those interested can consult Locker::_do_cap_update() in src/mds/Locker.cc and src/include/encoding.h in the Ceph server code (git://github.com/ceph/ceph). I also checked the server side for flock_len decoding, and I believe that also happens correctly, by virtue of having been declared __le32 in struct ceph_mds_cap_reconnect, in src/include/ceph_fs.h.

commit 14d2f38d upstream. An osd client has a red-black tree describing its osds, and occasionally we would get crashes due to one of these trees tree becoming corrupt somehow. The problem turned out to be that reset_changed_osds() was being called without protection of the osd client request mutex. That function would call __reset_osd() for any osd that had changed, and __reset_osd() would call __remove_osd() for any osd with no outstanding requests, and finally __remove_osd() would remove the corresponding entry from the red-black tree. Thus, the tree was getting modified without having any lock protection, and was vulnerable to problems due to concurrent updates. This appears to be the only osd tree updating path that has this problem. It can be fairly easily fixed by moving the call up a few lines, to just before the request mutex gets dropped in kick_requests(). This resolves: http://tracker.ceph.com/issues/5043Signed-off-by:

commit 6a76f8c0 upstream. Currently set_ftrace_pid and set_graph_function files use seq_lseek for their fops. However seq_open() is called only for FMODE_READ in the fops->open() so that if an user tries to seek one of those file when she open it for writing, it sees NULL seq_file and then panic. It can be easily reproduced with following command: $ cd /sys/kernel/debug/tracing $ echo 1234 | sudo tee -a set_ftrace_pid In this example, GNU coreutils' tee opens the file with fopen(, "a") and then the fopen() internally calls lseek().

commit b7ea85a4 upstream. When GPU acceleration is disabled, drm_vblank_cleanup() will free the vblank-related data, such as vblank_refcount, vblank_inmodeset, etc. But we found that drm_vblank_post_modeset() may be called after the cleanup, which use vblank_refcount and vblank_inmodeset. And this will cause a kernel panic. Fix this by return immediately if dev->num_crtcs is zero. This is the same thing that drm_vblank_pre_modeset() does.

commit e49f3959 upstream. The current radeon driver initialization routines, when using KMS, are written so that the IRQ installation routine is called before initializing the WB buffer and the CP rings. With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.

commit b8b3de22 upstream. RTAS token "ibm,get-config-addr-info" or ibm,get-config-addr-info2" are used to retrieve the PE address according to PCI address, which made up of domain/bus/slot/function. If we don't have those 2 tokens, the domain/bus/slot/function would be used as the address for EEH RTAS operations. Some older f/w might not have those 2 tokens and that blocks the EEH functionality to be initialized. It was introduced by commit e2af155c ("powerpc/eeh: pseries platform EEH initialization"). The patch skips the check on those 2 tokens so we can bring up EEH functionality successfully. And domain/bus/slot/function will be used as address for EEH RTAS operations. Reported-by:

commit fdc03438 upstream. This patch reverts commit 3e619d04 (USB: EHCI: fix bug in scheduling periodic split transfers). The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...

commit 331de00a upstream. It is possible that we fail on xhci_mem_init, just before doing the INIT_LIST_HEAD, and calling xhci_mem_cleanup. Problem is that, the list_for_each_entry_safe macro, assumes list heads are initialized (not NULL), and dereferences their 'next' pointer, causing a kernel panic if this is not yet initialized.

commit 77df9e0b upstream. Commit 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware) was a workaround for systems using the SN65LVPE502CP, controller, but it introduced a bug in resume from hibernate. The fix created a timer, comp_mode_recovery_timer, which is deleted from a timer list when xhci_suspend() is called. However, the hibernate image, including the timer list containing the comp_mode_recovery_timer, had already been saved before the timer was deleted. Upon resume from hibernate, the list containing the comp_mode_recovery_timer is restored from the image saved to disk, and xhci_resume(), assuming that the timer had been deleted by xhci_suspend(), makes a call to compliance_mode_recoery_timer_init(), which creates a new instance of the comp_mode_recovery_timer and attempts to place it into the same list in which it is already active, thus corrupting the list during the list_add() call. At this point, a call trace is emitted indicating the list corruption. Soon afterward, the system locks up, the watchdog times out, and the ensuing NMI crashes the system. The problem did not occur when resuming from suspend. In suspend, the image in RAM remains exactly as it was when xhci_suspend() deleted the comp_mode_recovery_timer, so there is no problem when xhci_resume() creates a new instance of this timer and places it in the still empty list. This patch avoids the problem by deleting the timer in xhci_resume() when resuming from hibernate. Now xhci_resume() can safely make the call to create a new instance of this timer, whether returning from suspend or hibernate. Thanks to Alan Stern for his help with understanding the problem. [Sarah reworked this patch to cover the case where the xHCI restore register operation fails, and (temp & STS_SRE) is true (and we re-init the host, including re-init for the compliance mode), but hibernate is false. The original patch would have caused list corruption in this case.] This patch should be backported to kernels as old as 3.2, that contain the commit 71c731a2 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by:

commit a4f46bb9 upstream. In the latest V-series bios DMI_PRODUCT_VERSION does not contain the string Lenovo or Thinkpad, but is set to the model number, this causes the thinkpad_acpi module to fail to load. Recognize laptop as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.
