2018-08-27x86/pae: use 64 bit atomic xchg function in native_ptep_get_and_clearJuergen Gross
Using only 32-bit writes for the pte will result in an intermediate L1TF vulnerable PTE. When running as a Xen PV guest this will at once switch the guest to shadow mode resulting in a loss of performance. Use arch_atomic64_xchg() instead which will perform the requested operation atomically with all 64 bits. Some performance considerations according to: https://software.intel.com/sites/default/files/managed/ad/dc/Intel-Xeon-Scalable-Processor-throughput-latency.pdf The main number should be the latency, as there is no tight loop around native_ptep_get_and_clear(). "lock cmpxchg8b" has a latency of 20 cycles, while "lock xchg" (with a memory operand) isn't mentioned in that document. "lock xadd" (with xadd having 3 cycles less latency than xchg) has a latency of 11, so we can assume a latency of 14 for "lock xchg".

2018-08-27blk-wbt: improve waking of tasksJens Axboe
We have two potential issues: 1) After commit 2887e41b910b, we only wake one process at the time when we finish an IO. We really want to wake up as many tasks as can queue IO. Before this commit, we woke up everyone, which could cause a thundering herd issue. 2) A task can potentially consume two wakeups, causing us to (in practice) miss a wakeup. Fix both by providing our own wakeup function, which stops __wake_up_common() from waking up more tasks if we fail to get a queueing token. With the strict ordering we have on the wait list, this wakes the right tasks and the right amount of tasks. Based on a patch from Jianchao Wang <jianchao.w.wang@oracle.com>.

This reverts commit 328728630d9f2bf14b82ca30b5e47489beefe361. There is fundamental issue in commit 328728630d9f2bf1 (scsi: core: avoid host-wide host_busy counter for scsi_mq) because SCSI's host busy counter may not be same with counter of blk-mq's inflight tags, especially in case of none io scheduler.

2018-08-27staging: wilc1000: revert "fix TODO to compile spi and sdio components in ↵Arnd Bergmann
single module" The TODO item named "make spi and sdio components coexist in one build" was apparently addressed a long time ago, but never removed from the TODO file. However, the new patch that tries to address it actually makes it worse again by duplicating the common parts of the driver into two separate modules rather than sharing them. This also introduces a build regression when one of the two is built-in while the other is a loadable module: drivers/staging/wilc1000/wilc_debugfs.o:(.data+0x10): undefined reference to `__this_module' Reverting the patch makes it build again. I'm leaving the TODO file modification though, as there is nothing left to do for this item. A related problem however still seems to exist: one still cannot have multiple concurrent instances of wilc1000 devices present in the system, as there are lots of shared global variables such as host_interface.c:static struct wilc_vif *periodic_rssi_vif; wilc_sdio.c:static struct wilc_sdio g_sdio; wilc_wlan.c:static enum chip_ps_states chip_ps_state = CHIP_WAKEDUP; wilc_wlan.c:static u32 pending_acks; wilc_wfi_cfgoperations.c:int wilc_connecting; In order to have multiple instances working (sdio, spi, or mixed), all such variables need to be dynamically allocated per instance and stored in 'struct wilc' or one of the structures referenced by it.

2018-08-27scsi: lpfc: Correct MDS diag and nvmet configurationJames Smart
A recent change added some MDS processing in the lpfc_drain_txq routine that relies on the fcp_wq being allocated. For nvmet operation the fcp_wq is not allocated because it can only be an nvme-target. When the original MDS support was added LS_MDS_LOOPBACK was defined wrong, (0x16) it should have been 0x10 (decimal value used for hex setting). This incorrect value allowed MDS_LOOPBACK to be set simultaneously with LS_NPIV_FAB_SUPPORTED, causing the driver to crash when it accesses the non-existent fcp_wq. Correct the bad value setting for LS_MDS_LOOPBACK. Fixes: ae9e28f36a6c ("lpfc: Add MDS Diagnostic support.")

2018-08-27x86/speculation/l1tf: Increase l1tf memory limit for Nehalem+Andi Kleen
On Nehalem and newer core CPUs the CPU cache internally uses 44 bits physical address space. The L1TF workaround is limited by this internal cache address width, and needs to have one bit free there for the mitigation to work. Older client systems report only 36bit physical address space so the range check decides that L1TF is not mitigated for a 36bit phys/32GB system with some memory holes. But since these actually have the larger internal cache width this warning is bogus because it would only really be needed if the system had more than 43bits of memory. Add a new internal x86_cache_bits field. Normally it is the same as the physical bits field reported by CPUID, but for Nehalem and newerforce it to be at least 44bits. Change the L1TF memory size warning to use the new cache_bits field to avoid bogus warnings and remove the bogus comment about memory size.

2018-08-27dmaengine: mic_x100_dma: use devm_kzalloc to fix an issueHuang Shijie
The following patch introduced an issue. commit f6206f00d8c5 ("dmaengine: mic_x100_dma: use the new helper to simplify the code") This issue is : kfree(mic_dma_dev) ..... dma_async_device_unregister(mic_dma_dev->device); Free the memory, and use it again. So use devm_kzalloc to allocate mic_dma_dev to fix it. When the Devres try to release the resources, it will call release at the following order: dma_async_device_unregister(mic_dma_dev->device); ..... kfree(mic_dma_dev) Fixes: f6206f00d8c5 ("dmaengine: mic_x100_dma: use the new helper to simplify the code") Signed-off-by: Huang Shijie <sjhuang@iluvatar.ai> Signed-off-by: Vinod Koul <vkoul@kernel.org>

2018-08-27drm/mediatek: update some variable name from ovl to compStu Hsieh
This patch update some variable name from ovl to comp Because RDMA would be first HW in ddp, the naming ovl should be change to comp. Signed-off-by: Stu Hsieh <stu.hsieh@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
2018-08-27drm/mediatek: use layer_nr function to get layer number to init planeStu Hsieh
This patch use layer_nr function to get layer number to init plane When plane init in crtc create, it use the number of OVL layer to init plane. That's OVL can read 4 memory address. For mt2712 third ddp, it use RDMA to read memory. RDMA can read 1 memory address, so it just init one plane. For compatibility, this patch use mtk_ddp_comp_layer_nr function to get layer number from their HW component in ddp for plane init.

This patch add function to return RDMA layer number RDMA always has one layer. Signed-off-by: Stu Hsieh <stu.hsieh@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
2018-08-27drm/mediatek: add function to return OVL layer numberStu Hsieh
This patch add function to return OVL layer number For now, MT8173, MT2712, MT2701 OVL all has 4 layer. Signed-off-by: Stu Hsieh <stu.hsieh@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
