The streg_cbdata can have a negative error value. So, it should be an integer, and not u8, as reported by smatch: drivers/media/radio/wl128x/fmdrv_common.c:1517 fmc_prepare() warn: assigning (-115) to unsigned variable 'fmdev->streg_cbdata' Signed-off-by:Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Thankfully, there's just one place at saa717x driver that uses multibyte read (for status report, via printk). Yet, let's fix it. From saa717x_write(), it is clear that the bytes are in little endian: mm1[4] = (value >> 16) & 0xff; mm1[3] = (value >> 8) & 0xff; mm1[2] = value & 0xff; So, the same order should be valid for read too.

Instead of parsing the link-frequencies property in the driver, let v4l2_of_alloc_parse_endpoint() do it. Signed-off-by:
Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by:

Sakari Ailus authored
The link-frequencies property is a variable length array of link frequencies in an endpoint. The array is needed by an increasing number of drivers, so it makes sense to add it to struct v4l2_of_endpoint. However, the length of the array is variable and the size of struct v4l2_of_endpoint is fixed since it is allocated by the caller. The options here are 1. to define a fixed maximum limit of link frequencies that has to be the global maximum of all boards. This is seen as problematic since the maximum could be largish, and everyone hitting the problem would need to submit a patch to fix it, or 2. parse the property in every driver. This doesn't sound appealing as two of the three implementations submitted to linux-media were wrong, and one of them was even merged before this was noticed, or 3. change the interface so that allocating and releasing memory according to the size of the array is possible. This is what the patch does. v4l2_of_alloc_parse_endpoint() is just like v4l2_of_parse_endpoint(), but it will allocate the memory resources needed to store struct v4l2_of_endpoint and the additional arrays pointed to by this struct. A corresponding release function v4l2_of_free_endpoint() is provided to release the memory allocated by v4l2_of_alloc_parse_endpoint(). In addition to this, the link-frequencies property is parsed as well, and the result is stored to struct v4l2_of_endpoint field link_frequencies. Signed-off-by:

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with SS == 0 results in an invalid usermode state in which SS is apparently equal to __USER_DS but causes #SS if used. Work around the issue by setting SS to __KERNEL_DS __switch_to, thus ensuring that SYSRET never happens with SS set to NULL. This was exposed by a recent vDSO cleanup.

Pull intel iommu updates from David Woodhouse: "This lays a little of the groundwork for upcoming Shared Virtual Memory support — fixing some bogus #defines for capability bits and adding the new ones, and starting to use the new wider page tables where we can, in anticipation of actually filling in the new fields therein. It also allows graphics devices to be assigned to VM guests again. This got broken in 3.17 by disallowing assignment of RMRR-afflicted devices. Like USB, we do understand why there's an RMRR for graphics devices — and unlike USB, it's actually sane. So we can make an exception for graphics devices, just as we do USB controllers. Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty hack to allow broken BIOSes to forbid us from using X2APIC when they do stupid and invasive things and would break if we did. Someone noticed that since Windows doesn't have full IOMMU support for DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid initialising the IOMMU on the graphics unit altogether. This means that it would be available for use in "driver mode", where the IOMMU registers are made available through a BAR of the graphics device and the graphics driver can do SVM all for itself. So they started setting the X2APIC_OPT_OUT bit on *all* platforms with SVM capabilities. And even the platforms which *might*, if the planets had been aligned correctly, possibly have had SVM capability but which in practice actually don't" * git://git.infradead.org/intel-iommu: iommu/vt-d: support extended root and context entries iommu/vt-d: Add new extended capabilities from v2.3 VT-d specification iommu/vt-d: Allow RMRR on graphics devices too iommu/vt-d: Print x2apic opt out info instead of printing a warning iommu/vt-d: kill bogus ecap_niotlb_iunits()
