IB/mlx5: Fix scatter to CQE in DCT QP creation

2019-04-18T06:13:41Z

When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command since it tried to treat it as as QP create mailbox command instead of a DCT create command. The corrupted mailbox command causes userspace to malfunction as the device doesn't create the QP as expected. A new mlx5 capability is exposed to user-space which ensures that it will not enable the feature on DCT without this fix in the kernel.

Pull sound fixes from Takashi Iwai: "Well, this one became unpleasantly larger than previous pull requests, but it's a kind of usual pattern: now it contains a collection of ASoC fixes, and nothing to worry too much. The fixes for ASoC core (DAPM, DPCM, topology) are all small and just covering corner cases.

ASoC: Fixes for v5.1 A few core fixes along with the driver specific ones, mainly fixing small issues that only affect x86 platforms for various reasons (their unusual machine enumeration mechanisms mainly, plus a fix for error handling in topology). There's some of the driver fixes that look larger than they are, like the hdmi-codec changes which resulted in an indentation change, and most of the other large changes are for new drivers like the STM32 changes.

ethtool: avoid signed-unsigned comparison in ethtool_validate_speed()

2019-04-08T23:30:43Z

When building C++ userspace code that includes ethtool.h with "-Werror -Wall", g++ complains about signed-unsigned comparison in ethtool_validate_speed() due to definition of SPEED_UNKNOWN as -1. Explicitly cast SPEED_UNKNOWN to __u32 to match type of ethtool_validate_speed() argument. Signed-off-by: Michael Zhivich Signed-off-by: David S. Miller

ALSA: uapi: #include in asound.h

2019-04-02T07:27:21Z

The uapi header asound.h defines types based on struct timespec. We need to #include to get access to the definition of this struct. Previously, we encountered the following error message when building applications with a clang/bionic toolchain: kernel-headers/sound/asound.h:350:19: error: field has incomplete type 'struct timespec' struct timespec trigger_tstamp; ^ The absence of the time.h #include statement does not cause build errors with glibc, because its version of stdlib.h indirectly includes time.h.

Pull char/misc driver fixes from Greg KH: "Here are some binder, habanalabs, and vboxguest driver fixes for 5.1-rc3. The Binder fixes resolve some reported issues found by testing, first by the selinux developers, and then earlier today by syzbot. The habanalabs fixes are all minor, resolving a number of tiny things. The vboxguest patches are a bit larger. They resolve the fact that virtual box decided to change their api in their latest release in a way that broke the existing kernel code, despite saying that they were never going to do that. So this is a bit of a "new feature", but is good to get merged so that 5.1 will work with the latest release. The changes are not large and of course virtual box "swears" they will not break this again, but no one is holding their breath here. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: virt: vbox: Implement passing requestor info to the host for VirtualBox 6.0.x binder: fix race between munmap() and direct reclaim binder: fix BUG_ON found by selinux-testsuite habanalabs: cast to expected type habanalabs: prevent host crash during suspend/resume habanalabs: perform accounting for active CS habanalabs: fix mapping with page size bigger than 4KB habanalabs: complete user context cleanup before hard reset habanalabs: fix bug when mapping very large memory area habanalabs: fix MMU number of pages calculation

KVM: export and iif KVM is supported

2019-03-28T16:27:42Z

I do not see any consistency about headers_install of and . According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both and are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] is exported, but is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither nor is exported csky, nds32, riscv This does not match to the actual KVM support. At least, [2] is half-baked. Nor do arch maintainers look like they care about this. For example, commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild") exported to user-space in order to fix an in-kernel build error. We have two ways to make this consistent: [A] export both and for all architectures, irrespective of the KVM support [B] Match the header export of and to the KVM support My first attempt was [A] because the code looks cleaner, but Paolo suggested [B]. So, this commit goes with [B]. For most architectures, was moved to the kernel-space. I changed include/uapi/linux/Kbuild so that it checks generated asm/kvm_para.h as well as check-in ones. After this commit, there will be two groups: [1] Both and are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither nor is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa Signed-off-by: Masahiro Yamada Acked-by: Cornelia Huck Signed-off-by: Paolo Bonzini
