2013-05-15workqueue: don't perform NUMA-aware allocations on offline nodes in ↵Tejun Heo1-1/+2
wq_numa_init() wq_numa_init() builds per-node cpumasks which are later used to make unbound workqueues NUMA-aware. The cpumasks are allocated using alloc_cpumask_var_node() for all possible nodes. Unfortunately, on machines with off-line nodes, this leads to NUMA-aware allocations on existing bug offline nodes, which in turn triggers BUG in the memory allocation code. Fix it by using NUMA_NO_NODE for cpumask allocations for offline nodes. kernel BUG at include/linux/gfp.h:323! invalid opcode: 0000 [#1] SMP Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.9.0+ #1 Hardware name: ProLiant BL465c G7, BIOS A19 12/10/2011 task: ffff880234608000 ti: ffff880234602000 task.ti: ffff880234602000 RIP: 0010:[<ffffffff8117495d>] [<ffffffff8117495d>] new_slab+0x2ad/0x340 RSP: 0000:ffff880234603bf8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff880237404b40 RCX: 00000000000000d0 RDX: 0000000000000001 RSI: 0000000000000003 RDI: 00000000002052d0 RBP: ffff880234603c28 R08: 0000000000000000 R09: 0000000000000001 R10: 0000000000000001 R11: ffffffff812e3aa8 R12: 0000000000000001 R13: ffff8802378161c0 R14: 0000000000030027 R15: 00000000000040d0 FS: 0000000000000000(0000) GS:ffff880237800000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffff88043fdff000 CR3: 00000000018d5000 CR4: 00000000000007f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Stack: ffff880234603c28 0000000000000001 00000000000000d0 ffff8802378161c0 ffff880237404b40 ffff880237404b40 ffff880234603d28 ffffffff815edba1 ffff880237816140 0000000000000000 ffff88023740e1c0 Call Trace: [<ffffffff815edba1>] __slab_alloc+0x330/0x4f2 [<ffffffff81174b25>] kmem_cache_alloc_node_trace+0xa5/0x200 [<ffffffff812e3aa8>] alloc_cpumask_var_node+0x28/0x90 [<ffffffff81a0bdb3>] wq_numa_init+0x10d/0x1be [<ffffffff81a0bec8>] init_workqueues+0x64/0x341 [<ffffffff810002ea>] do_one_initcall+0xea/0x1a0 [<ffffffff819f1f31>] kernel_init_freeable+0xb7/0x1ec [<ffffffff815d50de>] kernel_init+0xe/0xf0 [<ffffffff815ff89c>] ret_from_fork+0x7c/0xb0 Code: 45 84 ac 00 00 00 f0 41 80 4d 00 40 e9 f6 fe ff ff 66 0f 1f 84 00 00 00 00 00 e8 eb 4b ff ff 49 89 c5 e9 05 fe ff ff <0f> 0b 4c 8b 73 38 44 89 ff 81 cf 00 00 20 00 4c 89 f6 48 c1 ee Signed-off-by: Tejun Heo <[email protected]> Reported-and-Tested-by: Lingzhu Xiang <[email protected]>

2013-05-15cpufreq: Preserve sysfs files across suspend/resumeSrivatsa S. Bhat2-6/+5
The file permissions of cpufreq per-cpu sysfs files are not preserved across suspend/resume because we internally go through the CPU Hotplug path which reinitializes the file permissions on CPU online. But the user is not supposed to know that we are using CPU hotplug internally within suspend/resume (IOW, the kernel should not silently wreck the user-set file permissions across a suspend cycle). Therefore, we need to preserve the file permissions as they are across suspend/resume. The simplest way to achieve that is to just not touch the sysfs files at all - ie., just ignore the CPU hotplug notifications in the suspend/resume path (_FROZEN) in the cpufreq hotplug callback.

Following commit 6b772e8f9 (ACPI: Update PNPID match handling for notify), the acpi_scan_init_hotplug() calls acpi_set_pnp_ids() which allocates acpi_hardware_id and copies a few strings (kstrdup). If the devices does not have hardware_id set, the function exits without freeing the previously allocated ids (and kmemleak complains). This patch calls simply changes 'return' on error to a 'goto out' which calls acpi_free_pnp_ids().

2013-05-15NTB: Correctly handle receive buffers of the minimal sizeJon Mason1-3/+5

2013-05-15NTB: reset tx_index on link toggleJon Mason1-1/+1
If the NTB link toggles, the driver could stop receiving due to the tx_index not being set to 0 on the transmitting size on a link-up event. This is due to the driver expecting the incoming data to start at the beginning of the receive buffer and not at a random place. Signed-off-by: Jon Mason <[email protected]>
2013-05-15NTB: Link toggle memory leakJon Mason1-12/+20
Each link-up will allocate a new NTB receive buffer when the NTB properties are negotiated with the remote system. These allocations did not check for existing buffers and thus did not free them.

2013-05-15USB: OHCI: fix logic for scheduling isochronous URBsAlan Stern1-14/+18
The isochronous scheduling logic in ohci-hcd has a bug. The calculation for skipping TDs that are too late should be carried out only in the !URB_ISO_ASAP case. When URB_ISO_ASAP is set, the URB is pushed back so that none of the TDs are too late, which would cause the calculation to overflow. The patch also fixes the calculation to avoid overflow in the case where the frame value wraps around. This should be applied to -stable kernels going back to 3.8.

Commits c44b225077bb1fb25ed5cd5c4f226897b91bedd4 (UHCI: implement new semantics for URB_ISO_ASAP) and 6a41b4d3fe8cd4cc95181516fc6fba7b1747a27c (OHCI: implement new semantics for URB_ISO_ASAP) increased the latency for isochronous URBs in uhci-hcd and ohci-hcd respectively to 2 milliseconds, in an attempt to avoid underruns. It turns out that not only was this unnecessary -- 1-ms latency works okay -- it also causes problems with certain application loads such as real-time audio. This patch changes the latency for both drivers back to 1 ms. This should be applied to -stable kernels going back to 3.8.

2013-05-15USB: UHCI: fix for suspend of virtual HP controllerAlan Stern1-1/+2
HP's virtual UHCI host controller takes a long time to suspend (several hundred microseconds), even when no devices are attached. This provokes a warning message from uhci-hcd in the auto-stop case. To prevent this from happening, this patch adds a test to avoid performing an auto-stop when the wait_for_hp quirk flag is set. The controller will still suspend through the normal runtime PM mechanism. And since that pathway includes a 1-ms delay, the slowness of the virtual hardware won't matter.

2013-05-15USB: fix Kconfig logic for USB_UHCI_HCDAlan Stern1-12/+5
The Kconfig settings for uhci-hcd are too permissive; they allow the driver to be built without any bus-glue modules configured (USB_UHCI_HCD enabled, PCI disabled, SPARC_LEON disabled, ARCH_VT8500 enabled, and USB_UHCI_PLATFORM disabled). This patch fixes the problem by rearranging the dependencies. Now the platform-dependent config options don't depend on USB_UHCI_HCD; instead it depends on them. Furthermore, there is no user-selectable choice as to which glue modules will be built. If USB_UHCI_HCD is enabled then all applicable bus glues will be built.

2013-05-15USB: xHCI: override bogus bulk wMaxPacketSize valuesAlan Stern1-8/+9
This patch shortens the logic in xhci_endpoint_init() by moving common calculations involving max_packet and max_burst outside the switch statement, rather than repeating the same code in multiple case-specific statements. It also replaces two usages of max_packet which were clearly intended to be max_burst all along. More importantly, it compensates for a common bug in high-speed bulk endpoint descriptors. In many devices there is a bulk endpoint having a wMaxPacketSize value smaller than 512, which is forbidden by the USB spec. Some xHCI controllers can't handle this and refuse to accept the endpoint. This patch changes the max_packet value to 512, which allows the controller to use the endpoint properly. In practice the bogus maxpacket size doesn't matter, because none of the transfers sent via these endpoints are longer than the maxpacket value anyway.

2013-05-15rcu: Don't allocate bootmem from rcu_init()Sasha Levin1-1/+1
When rcu_init() is called we already have slab working, allocating bootmem at that point results in warnings and an allocation from slab. This commit therefore changes alloc_bootmem_cpumask_var() to alloc_cpumask_var() in rcu_bootup_announce_oddness(), which is called from rcu_init().

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v3.10-rc2 Here's the initial set of fixes for v3.10-rc series. It countains miscellaneous fixes in numerous drivers. Many gadget drivers and PHY drivers learned that it's not necessary to platform_set_drvdata() twice, that's not necessary to check the resource pointer returned by platform_get_resource() when using devm_ioremap_resource() and they learned that we shouldn't return 0 in case of errors. DWC3 got a build fix for cases where DWC3 is marked as 'y' while gadget API is marked as 'm'. There's also a NULL pointer exception fix on usb_get_phy(), mxs-phy now knows which PHY type it is and s3c-hsotg is now passing proper arguments to usb_gadget_unmap_request(). Other than that there are some spelling fixes and kernel-doc warnings. Signed-of-by: Felipe Balbi <[email protected]>
