[Linux-stable-mirror] [for-next][PATCH 4/6] trace_uprobe: Display correct offset in uprobe_events

by Steven Rostedt

From: Ravi Bangoria <ravi.bangoria(a)linux.vnet.ibm.com> Recently, how the pointers being printed with %p has been changed by commit ad67b74d2469 ("printk: hash addresses printed with %p"). This is causing a regression while showing offset in the uprobe_events file. Instead of %p, use %px to display offset.

[Linux-stable-mirror] Applied "ASoC: rt5514-spi: Check the validity of drvdata pointer on resume" to the asoc tree

by Mark Brown

The patch ASoC: rt5514-spi: Check the validity of drvdata pointer on resume 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 509bf3a7d43ab173abc354df2a859229ede043c0 Mon Sep 17 00:00:00 2001 From: Marc Zyngier <marc.zyngier(a)arm.com> Date: Wed, 24 Jan 2018 14:50:00 +0000 Subject: [PATCH] ASoC: rt5514-spi: Check the validity of drvdata pointer on resume The rt5514-spi driver seem to assume the validity of the drvdata pointer on resume, which it may not be populated, leading to a not-so-nice crash. This stems from the fact that rt5514_spi_pcm_probe() is never called on my system (a kevin Chromebook). No idea why, but if it can happen, it is worth fixing.

[Linux-stable-mirror] [PATCH AUTOSEL for 4.4 01/35] KVM: x86: emulator: Return to user-mode on L1 CPL=0 emulation failure

by Sasha Levin

From: Liran Alon <liran.alon(a)oracle.com> [ Upstream commit 1f4dcb3b213235e642088709a1c54964d23365e9 ] On this case, handle_emulation_failure() fills kvm_run with internal-error information which it expects to be delivered to user-mode for further processing. However, the code reports a wrong return-value which makes KVM to never return to user-mode on this scenario.
