If DMA_ATTR_NO_WARN is passed to swiotlb_alloc_buffer(), it should be passed further down to swiotlb_tbl_map_single(). Otherwise we escape half of the warnings but still log the other half. This is one of the multiple causes of spurious warnings reported at: https://bugs.freedesktop.org/show_bug.cgi?id=104082Signed-off-by: NJean Delvare <jdelvare@suse.de> Fixes: 0176adb0 ("swiotlb: refactor coherent buffer allocation") Cc: Christoph Hellwig <hch@lst.de> Cc: Christian König <christian.koenig@amd.com> Cc: Michel Dänzer <michel@daenzer.net> Cc: Takashi Iwai <tiwai@suse.de> Cc: stable@vger.kernel.org # v4.16

Since the commit "8003c9ae: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae | After 8003c9ae Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae | After 8003c9ae Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration().

Pull rdma fixes from Doug Ledford: "This is our first pull request of the rc cycle. It's not that it's been overly quiet, we were just waiting on a few things before sending this off. For instance, the 6 patch series from Intel for the hfi1 driver had actually been pulled in on Tuesday for a Wednesday pull request, only to have Jason notice something I missed, so we held off for some testing, and then on Thursday had to respin the series because the very first patch needed a minor fix (unnecessary cast is all). There is a sizable hns patch series in here, as well as a reasonably largish hfi1 patch series, then all of the lines of uapi updates are just the change to the new official Linux-OpenIB SPDX tag (a bunch of our files had what amounts to a BSD-2-Clause + MIT Warranty statement as their license as a result of the initial code submission years ago, and the SPDX folks decided it was unique enough to warrant a unique tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4 and core/cache/cma updates to round out the bunch. None of it was overly large by itself, but in the 2 1/2 weeks we've been collecting patches, it has added up :-/. As best I can tell, it's been through 0day (I got a notice about my last for-next push, but not for my for-rc push, but Jason seems to think that failure messages are prioritized and success messages not so much). It's also been through linux-next. And yes, we did notice in the context portion of the CMA query gid fix patch that there is a dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage and remove it anywhere we can. Summary: - Various build fixes (USER_ACCESS=m and ADDR_TRANS turned off) - SPDX license tag cleanups (new tag Linux-OpenIB) - RoCE GID fixes related to default GIDs - Various fixes to: cxgb4, uverbs, cma, iwpm, rxe, hns (big batch), mlx4, mlx5, and hfi1 (medium batch)" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (52 commits) RDMA/cma: Do not query GID during QP state transition to RTR IB/mlx4: Fix integer overflow when calculating optimal MTT size IB/hfi1: Fix memory leak in exception path in get_irq_affinity() IB/{hfi1, rdmavt}: Fix memory leak in hfi1_alloc_devdata() upon failure IB/hfi1: Fix NULL pointer dereference when invalid num_vls is used IB/hfi1: Fix loss of BECN with AHG IB/hfi1 Use correct type for num_user_context IB/hfi1: Fix handling of FECN marked multicast packet IB/core: Make ib_mad_client_id atomic iw_cxgb4: Atomically flush per QP HW CQEs IB/uverbs: Fix kernel crash during MR deregistration flow IB/uverbs: Prevent reregistration of DM_MR to regular MR RDMA/mlx4: Add missed RSS hash inner header flag RDMA/hns: Fix a couple misspellings RDMA/hns: Submit bad wr RDMA/hns: Update assignment method for owner field of send wqe RDMA/hns: Adjust the order of cleanup hem table RDMA/hns: Only assign dqpn if IB_QP_PATH_DEST_QPN bit is set RDMA/hns: Remove some unnecessary attr_mask judgement RDMA/hns: Only assign mtu if IB_QP_PATH_MTU bit is set ...

This reverts commit 22072e83 as it is broken. Alan writes: What you can't see just from reading the patch is that in both cases (ehci->itd_pool and ehci->sitd_pool) there are two allocation paths -- the two branches of an "if" statement -- and only one of the paths calls dma_pool_[z]alloc. However, the memset is needed for both paths, and so it can't be eliminated. Given that it must be present, there's no advantage to calling dma_pool_zalloc rather than dma_pool_alloc.

Proxying the cpuif accesses at EL2 makes use of vcpu_data_guest_to_host and co, which check the endianness, which call into vcpu_read_sys_reg... which isn't mapped at EL2 (it was inlined before, and got moved OoL with the VHE optimizations). The result is of course a nice panic. Let's add some specialized cruft to keep the broken platforms that require this hack alive. But, this code used vcpu_data_guest_to_host(), which expected us to write the value to host memory, instead we have trapped the guest's read or write to an mmio-device, and are about to replay it using the host's readl()/writel() which also perform swabbing based on the host endianness. This goes wrong when both host and guest are big-endian, as readl()/writel() will undo the guest's swabbing, causing the big-endian value to be written to device-memory. What needs doing? A big-endian guest will have pre-swabbed data before storing, undo this. If its necessary for the host, writel() will re-swab it. For a read a big-endian guest expects to swab the data after the load. The hosts's readl() will correct for host endianness, giving us the device-memory's value in the register. For a big-endian guest, swab it as if we'd only done the load. For a little-endian guest, nothing needs doing as readl()/writel() leave the correct device-memory value in registers. Tested on Juno with that rarest of things: a big-endian 64K host. Based on a patch from Marc Zyngier.

From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

Commit 7ed1c190 (tools: fix cross-compile var clobbering) removed setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica (acpidump) in power/acpi: ld: unrecognized option '-D_LINUX' The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this particular change and let LD be $(CC) again. Note that the old behaviour was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by the commit 7ed1c190. We use $(CC) for that reason.
