Applied "ASoC: fsl_esai: Fix divisor calculation failure at lower ratio" to the asoc tree

by Mark Brown

The patch ASoC: fsl_esai: Fix divisor calculation failure at lower ratio has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From c656941df9bc80f7ec65b92ca73c42f8b0b62628 Mon Sep 17 00:00:00 2001 From: Nicolin Chen <nicoleotsuka(a)gmail.com> Date: Sun, 8 Apr 2018 16:57:35 -0700 Subject: [PATCH] ASoC: fsl_esai: Fix divisor calculation failure at lower ratio When the desired ratio is less than 256, the savesub (tolerance) in the calculation would become 0. This will then fail the loop- search immediately without reporting any errors. But if the ratio is smaller enough, there is no need to calculate the tolerance because PM divisor alone is enough to get the ratio. So a simple fix could be just to set PM directly instead of going into the loop-search.

[PATCH] x86/nmi: Enable nested do_nmi() handling for 64-bit kernels

by chenggang.qin＠linux.alibaba.com

From: Andy Lutomirski <luto(a)kernel.org> commit: 9d05041679904b12c12421cbcf9cb5f4860a8d7b upstream 32-bit kernels handle nested NMIs in C. Enable the exact same handling on 64-bit kernels as well. This isn't currently necessary, but it will become necessary once the asm code starts allowing limited nesting.

[PATCH V2] blk-mq: fix race between complete and BLK_EH_RESET_TIMER

by Ming Lei

The normal request completion can be done before or during handling BLK_EH_RESET_TIMER, and this race may cause the request to never be completed since driver's .timeout() may always return BLK_EH_RESET_TIMER. This issue can't be fixed completely by driver, since the normal completion can be done between returning .timeout() and handing BLK_EH_RESET_TIMER. This patch fixes this race by introducing rq state of MQ_RQ_COMPLETE_IN_RESET, and reading/writing rq's state by holding queue lock, which can be per-request actually, but just not necessary to introduce one lock for so unusual event.

I therefore think that the > only race free solution would be to do the clearing from > stop-machine context. But maybe I'm overlooking something. Currently and with the above mentioned patch there is no problem: Xen pv guests always use default_idle(), so mwait_idle() eventually playing with MSR_IA32_SPEC_CTRL won't affect us. In order to ensure that won't change in future default_idle() should never modify MSR_IA32_SPEC_CTRL. In case something like that would be required we should rather add another idle function doing that. Juergen

[merged] task_struct-only-use-anon-struct-under-randstruct-plugin.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: task_struct: only use anon struct under randstruct plugin has been removed from the -mm tree. Its filename was task_struct-only-use-anon-struct-under-randstruct-plugin.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Kees Cook <keescook(a)chromium.org> Subject: task_struct: only use anon struct under randstruct plugin The original intent for always adding the anonymous struct in task_struct was to make sure we had compiler coverage. However, this caused pathological padding of 40 bytes at the start of task_struct. Instead, move the anonymous struct to being only used when struct layout randomization is enabled.
