2017-01-04vfio-mdev: fix non-standard ioctl return val causing i386 build failPaul Gortmaker1-1/+1
What appears to be a copy and paste error from the line above gets the ioctl a ssize_t return value instead of the traditional "int". The associated sample code used "long" which meant it would compile for x86-64 but not i386, with the latter failing as follows: CC [M] samples/vfio-mdev/mtty.o samples/vfio-mdev/mtty.c:1418:20: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] .ioctl = mtty_ioctl, ^ samples/vfio-mdev/mtty.c:1418:20: note: (near initialization for ‘mdev_fops.ioctl’) cc1: some warnings being treated as errors Since in this case, vfio is working with struct file_operations; as such: long (*unlocked_ioctl) (struct file *, unsigned int, unsigned long); long (*compat_ioctl) (struct file *, unsigned int, unsigned long); ...and so here we just standardize on long vs. the normal int that user space typically sees and documents as per "man ioctl" and similar.

Florian Fainelli says: ==================== net: systemport: Fix padding vs. TSB insertion This patch series fixes how we pad the packets submitted to the SYSTEMPORT adapter, and how the transmit status block (prepended 8 bytes) fits in the picture. The first patch is not technically a bug fix, but is required for the second path to be applied and to greatly simplify the skb length calculation. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-04net: systemport: Pad packet before inserting TSBFlorian Fainelli1-9/+9
Inserting the TSB means adding an extra 8 bytes in front the of packet that is going to be used as metadata information by the TDMA engine, but stripped off, so it does not really help with the packet padding. For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP) we can end-up padding them after the TSB insertion, thus making them 64 bytes, but with the TDMA stripping off the first 8 bytes, they could still be smaller than 64 bytes which is required to ingress the switch. Fix this by swapping the padding and TSB insertion, guaranteeing that the packets have the right sizes.

2017-01-04nvmem: imx-ocotp: Fix wrong register sizeDaniel Schultz1-1/+1
All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is an exception and has only 2kbit fuses. In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is described in chapter 46.1.1 with: "32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)." In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is described in chapter 34.1.1 with: "32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)." Since the Freescale Linux kernel OCOTP driver works with a fuses size of 2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula to calculate the correct fuses size has to be 256x8.

2017-01-04arm64: restore get_current() optimisationMark Rutland1-1/+9
Commit c02433dd6de32f04 ("arm64: split thread_info from task stack") inverted the relationship between get_current() and current_thread_info(), with sp_el0 now holding the current task_struct rather than the current thead_info. The new implementation of get_current() prevents the compiler from being able to optimize repeated calls to either, resulting in a noticeable penalty in some microbenchmarks. This patch restores the previous optimisation by implementing get_current() in the same way as our old current_thread_info(), using a non-volatile asm statement.

Also included is removal of mach-omap2/gpio.c that is now dead code with device tree based booting that should be OK for the early -rc cycle: - A series of fixes to add empty chosen node to fix regressions caused for bootloaders that don't create chosen node as the decompressor needs the chosen node to merge command line and ATAGs into it - Fix missing logicpd-som-lv-37xx-devkit.dtb entry in Makefile - Fix regression for am437x timers - Fix wrong strcat for non-NULL terminated string - A series of changes to fix tps65217 interrupts to not use defines as we don't do that for interrupts - Two patches to fix USB VBUS detection on am57xx-idk and force it to peripheral mode until dwc3 role detection is working - Add missing dra72-evm-tps65917 missing voltage supplies accidentally left out of an earlier patch - Fix n900 eMMC detection when booted on qemu - Remove unwanted pr_err on failed memory allocation for prm_common.c - Remove legacy mach-omap2/gpio.c that now is dead code since we boot mach-omap2 in device tree only mode - Fix am572x-idk pcie1 by adding the missing gpio reset pin * tag 'omap-for-v4.10/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (23 commits) ARM: dts: am572x-idk: Add gpios property to control PCIE_RESETn ARM: OMAP2+: PRM: Delete an error message for a failed memory allocation ARM: dts: n900: Mark eMMC slot with no-sdio and no-sd flags ARM: dts: dra72-evm-tps65917: Add voltage supplies to usb_phy, mmc, dss ARM: dts: am57xx-idk: Put USB2 port in peripheral mode ARM: dts: am57xx-idk: Support VBUS detection on USB2 port dt-bindings: input: Specify the interrupt number of TPS65217 power button dt-bindings: power/supply: Update TPS65217 properties dt-bindings: mfd: Remove TPS65217 interrupts ARM: dts: am335x: Fix the interrupt name of TPS65217 ARM: omap2+: fixing wrong strcat for Non-NULL terminated string ARM: omap2+: am437x: rollback to use omap3_gptimer_timer_init() ARM: dts: omap3: Add DTS for Logic PD SOM-LV 37xx Dev Kit ARM: dts: dra7: Add an empty chosen node to top level DTSI ARM: dts: dm816x: Add an empty chosen node to top level DTSI ARM: dts: dm814x: Add an empty chosen node to top level DTSI ARM: dts: am4372: Add an empty chosen node to top level DTSI ARM: dts: am33xx: Add an empty chosen node to top level DTSI ARM: dts: omap5: Add an empty chosen node to top level DTSI ARM: dts: omap4: Add an empty chosen node to top level DTSI ...

2017-01-04iommu/amd: Fix the left value check of cmd bufferHuang Rui1-1/+1
The generic command buffer entry is 128 bits (16 bytes), so the offset of tail and head pointer should be 16 bytes aligned and increased with 0x10 per command. When cmd buf is full, head = (tail + 0x10) % CMD_BUFFER_SIZE. So when left space of cmd buf should be able to store only two command, we should be issued one COMPLETE_WAIT additionally to wait all older commands completed. Then the left space should be increased after IOMMU fetching from cmd buf. So left check value should be left <= 0x20 (two commands).

2017-01-04iommu/vt-d: Fix pasid table size encodingJacob Pan1-1/+22
Different encodings are used to represent supported PASID bits and number of PASID table entries. The current code assigns ecap_pss directly to extended context table entry PTS which is wrong and could result in writing non-zero bits to the reserved fields. IOMMU fault reason 11 will be reported when reserved bits are nonzero. This patch converts ecap_pss to extend context entry pts encoding based on VT-d spec. Chapter 9.4 as follows: - number of PASID bits = ecap_pss + 1 - number of PASID table entries = 2^(pts + 5) Software assigned limit of pasid_max value is also respected to match the allocation limitation of PASID table. cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> cc: Ashok Raj <ashok.raj@intel.com> Signed-off-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Tested-by: Mika Kuoppala <mika.kuoppala@intel.com> Fixes: 2f26e0a9c9860 ('iommu/vt-d: Add basic SVM PASID support') Signed-off-by: Joerg Roedel <jroedel@suse.de>
2017-01-04iommu/vt-d: Flush old iommu caches for kdump when the device gets context mappedXunlei Pang1-0/+19
We met the DMAR fault both on hpsa P420i and P421 SmartArray controllers under kdump, it can be steadily reproduced on several different machines, the dmesg log is like: HP HPSA Driver (v 3.4.16-0) hpsa 0000:02:00.0: using doorbell to reset controller hpsa 0000:02:00.0: board ready after hard reset. hpsa 0000:02:00.0: Waiting for controller to respond to no-op DMAR: Setting identity map for device 0000:02:00.0 [0xe8000 - 0xe8fff] DMAR: Setting identity map for device 0000:02:00.0 [0xf4000 - 0xf4fff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf6e000 - 0xbdf6efff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf6f000 - 0xbdf7efff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf7f000 - 0xbdf82fff] DMAR: Setting identity map for device 0000:02:00.0 [0xbdf83000 - 0xbdf84fff] DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Read] Request device [02:00.0] fault addr fffff000 [fault reason 06] PTE Read access is not set hpsa 0000:02:00.0: controller message 03:00 timed out hpsa 0000:02:00.0: no-op failed; re-trying After some debugging, we found that the fault addr is from DMA initiated at the driver probe stage after reset(not in-flight DMA), and the corresponding pte entry value is correct, the fault is likely due to the old iommu caches of the in-flight DMA before it. Thus we need to flush the old cache after context mapping is setup for the device, where the device is supposed to finish reset at its driver probe stage and no in-flight DMA exists hereafter. I'm not sure if the hardware is responsible for invalidating all the related caches allocated in the iommu hardware before, but seems not the case for hpsa, actually many device drivers have problems in properly resetting the hardware. Anyway flushing (again) by software in kdump kernel when the device gets context mapped which is a quite infrequent operation does little harm. With this patch, the problematic machine can survive the kdump tests.
