Revert "ASoC: Fail card instantiation if DAI format setup fails"

2019-09-06T08:22:23Z

This reverts commit 714a8438fc8ae88aa22c25065e241bce0260db13 which is commit 40aa5383e393d72f6aa3943a4e7b1aae25a1e43b upstream. Mark Brown writes: I nacked this patch when Sasha posted it - it only improves diagnostics and might make systems that worked by accident break since it turns things into a hard failure, it won't make anything that didn't work previously work.

mt76: mt76x0u: do not reset radio on resume

2019-09-06T08:22:23Z

commit 8f2d163cb26da87e7d8e1677368b8ba1ba4d30b3 upstream. On some machines mt76x0u firmware can hung during resume, what result on messages like below: [ 475.480062] mt76x0 1-8:1.0: Error: MCU response pre-completed!

x86/ptrace: fix up botched merge of spectrev1 fix

2019-09-06T08:22:23Z

I incorrectly merged commit 31a2fbb390fe ("x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()") when backporting it, as was graciously pointed out at https://grsecurity.net/teardown_of_a_failed_linux_lts_spectre_fix.php Resolve the upstream difference with the stable kernel merge to properly protect things.

i2c: piix4: Fix port selection for AMD Family 16h Model 30h

2019-09-06T08:22:23Z

[ Upstream commit c7c06a1532f3fe106687ac82a13492c6a619ff1c ] Family 16h Model 30h SMBus controller needs the same port selection fix as described and fixed in commit 0fe16195f891 ("i2c: piix4: Fix SMBus port selection for AMD Family 17h chips") commit 6befa3fde65f ("i2c: piix4: Support alternative port selection register") also fixed the port selection for Hudson2, but unfortunately this is not the exact same device and the AMD naming and PCI Device IDs aren't particularly helpful here. The SMBus port selection register is common to the following Families and models, as documented in AMD's publicly available BIOS and Kernel Developer Guides: 50742 - Family 15h Model 60h-6Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS) 55072 - Family 15h Model 70h-7Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS) 52740 - Family 16h Model 30h-3Fh (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) The Hudson2 PCI Device ID (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) is shared between Bolton FCH and Family 16h Model 30h, but the location of the SmBus0Sel port selection bits are different: 51192 - Bolton Register Reference Guide We distinguish between Bolton and Family 16h Model 30h using the PCI Revision ID: Bolton is device 0x780b, revision 0x15 Family 16h Model 30h is device 0x780b, revision 0x1F Family 15h Model 60h and 70h are both device 0x790b, revision 0x4A. The following additional public AMD BKDG documents were checked and do not share the same port selection register: 42301 - Family 15h Model 00h-0Fh doesn't mention any 42300 - Family 15h Model 10h-1Fh doesn't mention any 49125 - Family 15h Model 30h-3Fh doesn't mention any 48751 - Family 16h Model 00h-0Fh uses the previously supported index register SB800_PIIX4_PORT_IDX_ALT at 0x2e Signed-off-by: Andrew Cooks Signed-off-by: Jean Delvare Cc: stable@vger.kernel.org [v4.6+] Signed-off-by: Wolfram Sang Signed-off-by: Sasha Levin

NFS: Ensure O_DIRECT reports an error if the bytes read/written is 0

[ Upstream commit eb2c50da9e256dbbb3ff27694440e4c1900cfef8 ] If the attempt to resend the I/O results in no bytes being read/written, we must ensure that we report the error.

[ Upstream commit df3accb849607a86278a37c35e6b313635ccc48b ] Allow the caller to pass error information when cleaning up a failed I/O request so that we can conditionally take action to cancel the request altogether if the error turned out to be fatal.

KVM: arm/arm64: vgic-v2: Handle SGI bits in GICD_I{S,C}PENDR0 as WI

2019-09-06T08:22:22Z

[ Upstream commit 82e40f558de566fdee214bec68096bbd5e64a6a4 ] A guest is not allowed to inject a SGI (or clear its pending state) by writing to GICD_ISPENDR0 (resp. GICD_ICPENDR0), as these bits are defined as WI (as per ARM IHI 0048B 4.3.7 and 4.3.8). Make sure we correctly emulate the architecture.
