[PATCH v4 1/6] PCI: aardvark: Introduce an advk_pcie_valid_device() helper

by Thomas Petazzoni

In other to mimic other PCIe host controller drivers, introduce an advk_pcie_valid_device() helper, used in the configuration read/write functions. This patch by itself is not a fix, but it is required for a follow-up patch that is a fix, hence the Fixes tag and the Cc to stable.

[PATCH] mm/memblock: fix potential issue in memblock_search_pfn_nid()

by Wei Yang

memblock_search_pfn_nid() returns the nid and the [start|end]_pfn of the memory region where pfn sits in. While the calculation of start_pfn has potential issue when the regions base is not page aligned. For example, we assume PAGE_SHIFT is 12 and base is 0x1234. Current implementation would return 1 while this is not correct. This patch fixes this by using PFN_UP(). The original commit is commit e76b63f80d93 ("memblock, numa: binary search node id") and merged in v3.12.

[PATCH 1/2] crypto: thunderx_zip: Fix fallout from CONFIG_VMAP_STACK

by Jan Glauber

Enabling virtual mapped kernel stacks breaks the thunderx_zip driver. On compression or decompression the executing CPU hangs in an endless loop. The reason for this is the usage of __pa by the driver which does no longer work for an address that is not part of the 1:1 mapping. The zip driver allocates a result struct on the stack and needs to tell the hardware the physical address within this struct that is used to signal the completion of the request. As the hardware gets the wrong address after the broken __pa conversion it writes to an arbitrary address. The zip driver then waits forever for the completion byte to contain a non-zero value. Allocating the result struct from 1:1 mapped memory resolves this bug.

[PATCH for v3.18 00/18] Backport CVE-2017-13166 fixes to Kernel 3.18

by Mauro Carvalho Chehab

Hi Greg, Those are the backports meant to solve CVE-2017-13166 on Kernel 3.18. It contains two v4l2-ctrls fixes that are required to avoid crashes at the test application. I wrote two patches myself for Kernel 3.18 in order to solve some issues specific for Kernel 3.18 with aren't needed upstream. one is actually a one-line change backport. The other one makes sure that both 32-bits and 64-bits version of some ioctl calls will return the same value for a reserved field. I noticed an extra bug while testing it, but the bug also hits upstream, and should be backported all the way down all stable/LTS versions. So, I'll send it the usual way, after merging upsream.

[stable:v4.15] drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.

by Dhinakaran Pandiyan

If bios sets up an MST output and hardware state readout code sees this is an SST configuration, when disabling the encoder we end up calling ->post_disable_dp() hook instead of the MST version. Consequently, we write to the DP_SET_POWER dpcd to set it D3 state. Further along when we try enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up the MST hub. This results in continuous link training failures which keep the system busy delaying boot. We could identify bios MST boot discrepancy and handle it accordingly but a simple way to solve this is to write to the DP_SET_POWER dpcd for MST too. v2: Rebased on stable/linux-4.15.y and fixed minor conflict.
