The problem was that I was coming up with a different path for signing_key.x509 in the build directory if it didn't exist to if it did exist. This meant that the X.509 cert container object file would be rebuilt on the second rebuild in a build directory and the kernel would get relinked. - Unconditionally remove files generated by SYSTEM_TRUSTED_KEYRING=y when doing make mrproper. - Actually initialise the persistent-keyring semaphore for init_user_ns.

A few options were considered to fix this: 1/ sync all dma whenever a cpu copy branch is taken 2/ modify the page fault handler to hold off while dma is in-flight Option 1 adds yet more cpu overhead to an "offload" that struggles to compete with cpu-copy. Option 2 adds checks for behavior that is already documented as broken when using get_user_pages(). At a minimum a debug mode is warranted to catch and flag these violations of the dma-api vs get_user_pages(). Thanks to David for his reproducer.

On the Dell machines with codec whose Subsystem Id is 0x10280640, no external microphone can be detected when plugging a 3-ring headset. Using ALC255_FIXUP_DELL1_MIC_NO_PRESENCE can fix this problem. The codec (Vendor ID: 0x10ec0255) on the machine belongs to alc_269 family.

2013-12-18KVM: PPC: Book3S HV: Don't drop low-order page address bitsPaul Mackerras1-0/+1
Commit caaa4c804fae ("KVM: PPC: Book3S HV: Fix physical address calculations") unfortunately resulted in some low-order address bits getting dropped in the case where the guest is creating a 4k HPTE and the host page size is 64k. By getting the low-order bits from hva rather than gpa we miss out on bits 12 - 15 in this case, since hva is at page granularity. This puts the missing bits back in.

2013-12-17imx-drm: imx-drm-core: make imx_drm_crtc_register() saferRussell King1-2/+3
imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which leaves the CRTC attached to the DRM device. Also, it does setup after attaching the CRTC to the DRM device. Fix this by reordering the function such that we do the setup before drm_crtc_init(): this fixes both issues.

2013-12-17imx-drm: imx-tve: don't call sleeping functions beneath enable_lock spinlockRussell King1-9/+0
Enable lock claims that it is serializing tve_enable/disable calls. However, DRM already serialises mode sets with a mutex, which prevents encoder/connector functions being called concurrently. Secondly, holding a spinlock while calling clk_prepare_enable() is wrong; it will cause a might_sleep() warning should that debugging be enabled. So, let's just get rid of the enable_lock.

2013-12-17qlcnic: Fix TSS/RSS ring validation logic.Himanshu Madhani3-3/+8
o TSS/RSS ring validation does not take into account that either of these ring values can be 0. This patch fixes this validation and would fail set_channel operation if any of these ring value is 0. This regression was added as part of commit id 34e8c406fda5b5a9d2e126a92bab84cd28e3b5fa ("qlcnic: refactor Tx/SDS ring calculation and validation in driver.")

2013-12-17qlcnic: Fix usage of netif_tx_{wake, stop} api during link change.Himanshu Madhani1-8/+2
o Driver was using netif_tx_{stop,wake}_all_queues() api during link change event. Remove these api calls to manage queue start/stop event, as core networking stack will manage this based on netif_carrier_{on,off} call. These API's were modified as part of commit id 012ec81223aa45d2b80aeafb77392fd1a19c7b10 ("qlcnic: Multi Tx queue support for 82xx Series adapter.")

When using dt resources retrieval (interrupts and reg properties) there is no predefined order for these resources in the platform dev resources table. Retrieve resources using platform_get_resource and platform_get_irq functions instead of direct resource table entries to avoid resource type mismatch.

2013-12-17neigh: Netlink notification for administrative NUD state changeBob Gilligan1-0/+1
The neighbour code sends up an RTM_NEWNEIGH netlink notification if the NUD state of a neighbour cache entry is changed by a timer (e.g. from REACHABLE to STALE), even if the lladdr of the entry has not changed. But an administrative change to the the NUD state of a neighbour cache entry that does not change the lladdr (e.g. via "ip -4 neigh change ... nud ...") does not trigger a netlink notification. This means that netlink listeners will not hear about administrative NUD state changes such as from a resolved state to PERMANENT. This patch changes the neighbor code to generate an RTM_NEWNEIGH message when the NUD state of an entry is changed administratively.

2013-12-17staging: comedi: 8255_pci: fix for newer PCI-DIO48HIan Abbott1-3/+12
At some point, Measurement Computing / ComputerBoards redesigned the PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip. This meant they had to put their hardware registers in the PCI BAR 2 region instead of PCI BAR 1. Unfortunately, they kept the same PCI device ID for the new design. This means the driver recognizes the newer cards, but doesn't work (and is likely to screw up the local configuration registers of the PLX chip) because it's using the wrong region. Since the PCI subvendor and subdevice IDs were both zero on the old design, but are the same as the vendor and device on the new design, we can tell the old design and new design apart easily enough. Split the existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new entries, referenced by different entries in the PCI device ID table `pci_8255_pci_table[]`. Use the same board name for both entries.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: Third set of fixes for IIO in the 3.13 cycle. * Fix for a bug in the new cm36651 driver where it told the IIO driver it was providing a decimal part, but then didn't. Now it correctly tells the IIO core that it is only providing an integer value. This prevents random incorrect values being output on a sysfs read. * 3 fixes where drivers were miss specifying the endianness of their channels as output through the buffer interface. These were discovered whilst removing the terrible IIO_ST macro once and for all. The result is that userspace may be informed that the buffer elements are being output as little endian (on little endian platforms) when infact they are big endian. Thus userspace will handle them incorrectly. This incorrect buffer element specification is provided as sysfs attributes under iio:deviceN/scan_elements.

2013-12-17iio:imu:adis16400 fix pressure channel scan typeJonathan Cameron1-1/+6
A single channel in this driver was using the IIO_ST macro. This does not provide a parameter for setting the endianness of the channel. Thus this channel will have been reported as whatever is the native endianness of the cpu rather than big endian. This means it would be incorrect on little endian platforms.

missuse of the IIO_ST macro. This driver sets the shift value equal to IIO_BE (or 1) rather than setting that to 0 and specificying the endianness. This means the channel type is missreported as [be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness, rather than be:u16/16>>0 resulting in any userspace code using this information, miss converting the channel and generating thoroughly trashed data.
