2015-05-14firmware: dmi_scan: Fix ordering of product_uuidJean Delvare
In function dmi_present(), dmi_walk_early() calls dmi_table(), which calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last function makes a decision based on the value of global variable dmi_ver. The problem is that this variable is set right _after_ dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0 regardless of the actual version implemented. This causes /sys/class/dmi/id/product_uuid to always use the old ordering even on systems implementing DMI/SMBIOS 2.6 or later, which should use the new ordering. This is broken since kernel v3.8 for legacy DMI implementations and since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3 implementations with the 64-bit entry point are not affected. The first breakage does not matter much as in practice legacy DMI implementations are always for versions older than 2.6, which is when the UUID ordering changed. The second breakage is more problematic as it affects the vast majority of x86 systems manufactured since 2009.

2015-05-11iw_cxgb4: use wildcard mapping for getting remote addr infoSteve Wise
For listening endpoints bound to the wildcard address, we need to pass the wildcard address mapping to iwpm_get_remote_info() instead of the mapped address of the new child connection. Without this fix, and with iwarp port mapping enabled, each iw_cxgb4 connection that is spawned from a listening endpoint bound to the wildcard address, will generate an annoying dmesg entry about failing to find the remote address mapping info, and the connection state displayed in debugfs under /sys/kernel/debug/iw_cxgb4/<pci-slot-no>/eps will not have the peer's address/port mapping info.

2015-05-11iommu/arm-smmu: Fix sign-extension of upstream bus addresses at stage 1Will Deacon
Stage 1 translation is controlled by two sets of page tables (TTBR0 and TTBR1) which grow up and down from zero respectively in the ARMv8 translation regime. For the SMMU, we only care about TTBR0 and, in the case of a 48-bit virtual space, we expect to map virtual addresses 0x0 through to 0xffff_ffff_ffff. Given that some masters may be incapable of emitting virtual addresses targetting TTBR1 (e.g. because they sit on a 48-bit bus), the SMMU architecture allows bit 47 to be sign-extended, halving the virtual range of TTBR0 but allowing TTBR1 to be used. This is controlled by the SEP field in TTBCR2. The SMMU driver incorrectly enables this sign-extension feature, which causes problems when userspace addresses are programmed into a master device with the SMMU expecting to map the incoming transactions via TTBR0; if the top bit of address is set, we will instead get a translation fault since TTBR1 walks are disabled in the TTBCR. This patch fixes the issue by disabling sign-extension of a fixed virtual address bit and instead basing the behaviour on the upstream bus size: the incoming address is zero extended unless the upstream bus is only 49 bits wide, in which case bit 48 is used as the sign bit and is replicated to the upper bits.

spi: Fixes for v4.1 A few driver fixes plus two changes for the core, one to make the setup_transfer() callback optional which fixes crashes in some drivers which were updated to use new interfaces without apparent testing and one to ensure we don't expose the data buffers we use for dummy transfers to drivers which avoids potential issues with multiple accesses to them or reuse. # gpg: Signature made Sat 25 Apr 2015 10:59:47 BST using RSA key ID 5D5487D0 # gpg: key CD7BEEBC: no public key for trusted key - skipped # gpg: key CD7BEEBC marked as ultimately trusted # gpg: key AF88CD16: no public key for trusted key - skipped # gpg: key AF88CD16 marked as ultimately trusted # gpg: key 16005C11: no public key for trusted key - skipped # gpg: key 16005C11 marked as ultimately trusted # gpg: key 5621E907: no public key for trusted key - skipped # gpg: key 5621E907 marked as ultimately trusted # gpg: key 5C6153AD: no public key for trusted key - skipped # gpg: key 5C6153AD marked as ultimately trusted # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

2015-05-11drm/i915: Avoid GPU hang when coming out of s3 or s4Peter Antoine
This patch fixes a timing issue that causes a GPU hang when the system comes out of power saving. During pm_resume, We are submitting batchbuffers before enabling Interrupts this is causing us to miss the context switch interrupt, and in consequence intel_execlists_handle_ctx_events is not triggered. This patch is based on a patch from Deepak S <deepak.s@intel.com> from another platform. The patch fixes an issue introduced by: commit e7778be1eab918274f79603d7c17b3ec8be77386 drm/i915: Fix startup failure in LRC mode after recent init changes The above patch added a call to init_context() to fix an issue introduced by a previous patch. But, it then opened up a small timing window for the batches being added by the init_context (basically setting up the context) to complete before the interrupts have been turned on, thus hanging the GPU.

2015-05-10bnx2x: limit fw delay in kdump to 5s after bootMichal Schmidt
Commit 12a8541d5c82 "bnx2x: Delay during kdump load" added a 5 seconds delay to bnx2x's probe function in the kdump case to let the firmware realize the old driver is gone. The problem with the delay is that it is per-device, so if you have several bnx2x NICs in NPAR mode, the delays can accumulate to minutes. Fix it by adjusting the delay so that we do not wait more than necessary, i.e. no more delaying after 5 seconds of kernel boot time.

2015-05-11drm: Zero out invalid vblank timestamp in drm_update_vblank_count.Mario Kleiner
Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.

2015-05-09usbnet: avoid integer overflow in start_xmitJason A. Donenfeld
transfer_buffer_length is of type u32. It's therefore wrong to assign it to a signed integer. This patch avoids the overflow. It's worth noting that entry->length here is a long; perhaps it would be beneficial at somepoint to change this to be unsigned as well, if nothing else relies on its signedness for error conditions or the like.
