2018-09-04i2c: i801: fix DNV's SMBCTRL register offsetFelipe Balbi
DNV's iTCO is slightly different with SMBCTRL sitting at a different offset when compared to all other devices. Let's fix so that we can properly use iTCO watchdog.

2018-09-04dm verity: fix crash on bufio buffer that was allocated with vmallocMikulas Patocka
Since commit d1ac3ff008fb ("dm verity: switch to using asynchronous hash crypto API") dm-verity uses asynchronous crypto calls for verification, so that it can use hardware with asynchronous processing of crypto operations. These asynchronous calls don't support vmalloc memory, but the buffer data can be allocated with vmalloc if dm-bufio is short of memory and uses a reserved buffer that was preallocated in dm_bufio_client_create(). Fix verity_hash_update() so that it deals with vmalloc'd memory correctly.

2018-09-04drm/i915/gvt: Fix life cycle reference on KVM mmZhenyu Wang
Handle guest mm access life cycle properly with mmget()/mmput(). As noted by Linus, use_mm() depends on valid live page table but KVM's mmgrab() doesn't guarantee that. As vGPU usage depends on guest VM life cycle, need to make sure to use mmget()/mmput() to guarantee VM address access. v3: fix build v2: v1 caused a weird dependence issue which failed for vfio device release, which result invalid mdev vgpu and kvm state without proper release taken. This trys to put right reference around VM address space access instead.

2018-09-03bnxt_en: Do not adjust max_cp_rings by the ones used by RDMA.Michael Chan
Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number of MSIX vectors used by RDMA. There is one code path in open that needs to check the true max_cp_rings including any used by RDMA. This code is now checking for the reduced max_cp_rings which will fail when the number of cp rings is very small. To fix this in a clean way, we don't adjust max_cp_rings anymore. Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the reduced max_cp_rings when appropriate. Fixes: ec86f14ea506 ("bnxt_en: Add ULP calls to stop and restart IRQs.")

2018-09-02net: cadence: Fix a sleep-in-atomic-context bug in macb_halt_tx()Jia-Ju Bai
The kernel module may sleep with holding a spinlock. The function call paths (from bottom to top) in Linux-4.16 are: [FUNC] usleep_range drivers/net/ethernet/cadence/macb_main.c, 648: usleep_range in macb_halt_tx drivers/net/ethernet/cadence/macb_main.c, 730: macb_halt_tx in macb_tx_error_task drivers/net/ethernet/cadence/macb_main.c, 721: _raw_spin_lock_irqsave in macb_tx_error_task To fix this bug, usleep_range() is replaced with udelay(). This bug is found by my static analysis tool DSAC. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-02i2c: imx-lpi2c: Remove mx8dv compatible entryFabio Estevam
mx8dv never entered into production and there is no other place in the kernel referring to this SoC, so remove it from the driver's compatible entry. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2018-09-02i2c: uniphier-f: issue STOP only for last message or I2C_M_STOPMasahiro Yamada
This driver currently emits a STOP if the next message is not I2C_MD_RD. It should not do it because it disturbs the I2C_RDWR ioctl, where read/write transactions are combined without STOP between. Issue STOP only when the message is the last one _or_ flagged with I2C_M_STOP.

2018-09-02net: mvneta: reduce smp_processor_id() calling in mvneta_tx_done_gbeJisheng Zhang
In the loop of mvneta_tx_done_gbe(), we call the smp_processor_id() each time, move the call out of the loop to optimize the code a bit. Before the patch, the loop looks like(under arm64): ldr x1, [x29,#120] ... ldr w24, [x1,#36] ... bl 0 <_raw_spin_lock> str w24, [x27,#132] ... After the patch, the loop looks like(under arm64): ... bl 0 <_raw_spin_lock> str w23, [x28,#132] ... where w23 is loaded so be ready before the loop. >From another side, mvneta_tx_done_gbe() is called from mvneta_poll() which is in non-preemptible context, so it's safe to call the smp_processor_id() function once.

2018-09-02net: mvneta: Don't check NETIF_F_GRO ourselfJisheng Zhang
napi_gro_receive() checks NETIF_F_GRO bit as well, if the bit is not set, we will go through GRO_NORMAL in napi_skb_finish(), so fall back to netif_receive_skb_internal(), so we don't need to check NETIF_F_GRO ourself.
