2016-02-09net:Add sysctl_max_skb_fragsHans Westgaard Ry
Devices may have limits on the number of fragments in an skb they support. Current codebase uses a constant as maximum for number of fragments one skb can hold and use. When enabling scatter/gather and running traffic with many small messages the codebase uses the maximum number of fragments and may thereby violate the max for certain devices. The patch introduces a global variable as max number of fragments.

2016-02-09drm/i915: Pretend cursor is always on for ILK-style WM calculations (v2)Matt Roper
Due to our lack of two-step watermark programming, our driver has historically pretended that the cursor plane is always on for the purpose of watermark calculations; this helps avoid serious flickering when the cursor turns off/on (e.g., when the user moves the mouse pointer to a different screen). That workaround was accidentally dropped as we started working toward atomic watermark updates. Since we still aren't quite there yet with two-stage updates, we need to resurrect the workaround and treat the cursor as always active. v2: Tweak cursor width calculations slightly to more closely match the logic we used before the atomic overhaul began.

2016-02-09tcp: do not drop syn_recv on all icmp reportsEric Dumazet
Petr Novopashenniy reported that ICMP redirects on SYN_RECV sockets were leading to RST. This is of course incorrect. A specific list of ICMP messages should be able to drop a SYN_RECV. For instance, a REDIRECT on SYN_RECV shall be ignored, as we do not hold a dst per SYN_RECV pseudo request.

2016-02-09dma-buf: Remove range-based flushTiago Vignatti
This patch removes range-based information used for optimizations in begin_cpu_access and end_cpu_access. We don't have any user nor implementation using range-based flush. It seems a consensus that if we ever want something like that again (or even more robust using 2D, 3D sub-range regions) we can use the upcoming dma-buf sync ioctl for such.

2016-02-09drm: prime: Honour O_RDWR during prime-handle-to-fdDaniel Thompson
Currently DRM_IOCTL_PRIME_HANDLE_TO_FD rejects all flags except (DRM|O)_CLOEXEC making it difficult (maybe impossible) for userspace to mmap() the resulting dma-buf even when this is supported by the DRM driver. It is trivial to relax the restriction and permit read/write access. This is safe because the flags are seldom touched by drm; mostly they are passed verbatim to dma_buf calls. v3 (Tiago): removed unused flags variable from drm_prime_handle_to_fd_ioctl.

2016-02-08xen/arm: correctly handle DMA mapping of compound pagesIan Campbell
Currently xen_dma_map_page concludes that DMA to anything other than the head page of a compound page must be foreign, since the PFN of the page is that of the head. Fix the check to instead consider the whole of a compound page to be local if the PFN of the head passes the 1:1 check. We can never see a compound page which is a mixture of foreign and local sub-pages. The comment already correctly described the intention, but fixup the spelling and some grammar. This fixes the various SSH protocol errors which we have been seeing on the cubietrucks in our automated test infrastructure. This has been broken since commit 3567258d281b ("xen/arm: use hypercall to flush caches in map_page"), which was in v3.19-rc1. NB arch/arm64/.../xen/page-coherent.h also includes this file.

2016-02-08xen/scsiback: avoid warnings when adding multiple LUNs to a domainJuergen Gross
When adding more than one LUN to a frontend a warning for a failed assignment is issued in dom0 for each already existing LUN. Avoid this warning by checking for a LUN already existing when existence is allowed (scsiback_do_add_lun() called with try == 1). As the LUN existence check is needed now for a third time, factor it out into a function. This in turn leads to a more or less complete rewrite of scsiback_del_translation_entry() which will now return a proper error code in case of failure.

2016-02-08ARM: 8517/1: ICST: avoid arithmetic overflow in icst_hz()Linus Walleij
When trying to set the ICST 307 clock to 25174000 Hz I ran into this arithmetic error: the icst_hz_to_vco() correctly figure out DIVIDE=2, RDW=100 and VDW=99 yielding a frequency of 25174000 Hz out of the VCO. (I replicated the icst_hz() function in a spreadsheet to verify this.) However, when I called icst_hz() on these VCO settings it would instead return 4122709 Hz. This causes an error in the common clock driver for ICST as the common clock framework will call .round_rate() on the clock which will utilize icst_hz_to_vco() followed by icst_hz() suggesting the erroneous frequency, and then the clock gets set to this. The error did not manifest in the old clock framework since this high frequency was only used by the CLCD, which calls clk_set_rate() without first calling clk_round_rate() and since the old clock framework would not call clk_round_rate() before setting the frequency, the correct values propagated into the VCO. After some experimenting I figured out that it was due to a simple arithmetic overflow: the divisor for 24Mhz reference frequency as reference becomes 24000000*2*(99+8)=0x132212400 and the "1" in bit 32 overflows and is lost. But introducing an explicit 64-by-32 bit do_div() and casting the divisor into (u64) we get the right frequency back, and the right frequency gets set. Tested on the ARM Versatile.

2016-02-08mmc: pxamci: fix the device-tree probe deferral pathRobert Jarzmik
When the gpio driver is probed after the mmc one, the read/write gpio and card detection one return -EPROBE_DEFER. Unfortunately, the memory region remains requested, and upon the next probe, the probe will fail anyway with -EBUSY. Fix this by releasing the memory resource upon probe failure. More broadly, this patch uses devm_*() primitives whenever possible in the probe function. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2016-02-08drm/i915: Do not disable cxsr when crtc is disabled.Maarten Lankhorst
It's safe to assume cxsr is already disabled when the crtc is off. This prevents an unclaimed register warning when the required power wells are not enabled.

2016-02-08netfilter: tee: select NF_DUP_IPV6 unconditionallyArnd Bergmann
The NETFILTER_XT_TARGET_TEE option selects NF_DUP_IPV6 whenever IP6_NF_IPTABLES is enabled, and it ensures that it cannot be builtin itself if NF_CONNTRACK is a loadable module, as that is a dependency for NF_DUP_IPV6. However, NF_DUP_IPV6 can be enabled even if IP6_NF_IPTABLES is turned off, and it only really depends on IPV6. With the current check in tee_tg6, we call nf_dup_ipv6() whenever NF_DUP_IPV6 is enabled. This can however be a loadable module which is unreachable from a built-in xt_TEE: net/built-in.o: In function `tee_tg6': :(.text+0x67728): undefined reference to `nf_dup_ipv6' The bug was originally introduced in the split of the xt_TEE module into separate modules for ipv4 and ipv6, and two patches tried to fix it unsuccessfully afterwards. This is a revert of the the first incorrect attempt to fix it, going back to depending on IPV6 as the dependency, and we adapt the 'select' condition accordingly.
