[tip: ras/urgent] x86/mce: Fix logic and comments around MSR_PPIN_CTL

by tip-bot2 for Tony Luck

The following commit has been merged into the ras/urgent branch of tip: Commit-ID: 59b5809655bdafb0767d3fd00a3e41711aab07e6 Gitweb: https://git.kernel.org/tip/59b5809655bdafb0767d3fd00a3e41711aab07e6 Author: Tony Luck <tony.luck(a)intel.com> AuthorDate: Tue, 25 Feb 2020 17:17:37 -08:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Thu, 27 Feb 2020 21:36:42 +01:00 x86/mce: Fix logic and comments around MSR_PPIN_CTL There are two implemented bits in the PPIN_CTL MSR: Bit 0: LockOut (R/WO) Set 1 to prevent further writes to MSR_PPIN_CTL. Bit 1: Enable_PPIN (R/W) If 1, enables MSR_PPIN to be accessible using RDMSR. If 0, an attempt to read MSR_PPIN will cause #GP. So there are four defined values: 0: PPIN is disabled, PPIN_CTL may be updated 1: PPIN is disabled. PPIN_CTL is locked against updates 2: PPIN is enabled. PPIN_CTL may be updated 3: PPIN is enabled. PPIN_CTL is locked against updates Code would only enable the X86_FEATURE_INTEL_PPIN feature for case "2". When it should have done so for both case "2" and case "3". Fix the final test to just check for the enable bit. Also fix some of the other comments in this function.

[tip: x86/urgent] x86/pkeys: Manually set X86_FEATURE_OSPKE to preserve existing changes

by tip-bot2 for Sean Christopherson

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 735a6dd02222d8d070c7bb748f25895239ca8c92 Gitweb: https://git.kernel.org/tip/735a6dd02222d8d070c7bb748f25895239ca8c92 Author: Sean Christopherson <sean.j.christopherson(a)intel.com> AuthorDate: Wed, 26 Feb 2020 15:16:15 -08:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Thu, 27 Feb 2020 19:02:45 +01:00 x86/pkeys: Manually set X86_FEATURE_OSPKE to preserve existing changes Explicitly set X86_FEATURE_OSPKE via set_cpu_cap() instead of calling get_cpu_cap() to pull the feature bit from CPUID after enabling CR4.PKE. Invoking get_cpu_cap() effectively wipes out any {set,clear}_cpu_cap() changes that were made between this_cpu->c_init() and setup_pku(), as all non-synthetic feature words are reinitialized from the CPU's CPUID values. Blasting away capability updates manifests most visibility when running on a VMX capable CPU, but with VMX disabled by BIOS. To indicate that VMX is disabled, init_ia32_feat_ctl() clears X86_FEATURE_VMX, using clear_cpu_cap() instead of setup_clear_cpu_cap() so that KVM can report which CPU is misconfigured (KVM needs to probe every CPU anyways). Restoring X86_FEATURE_VMX from CPUID causes KVM to think VMX is enabled, ultimately leading to an unexpected #GP when KVM attempts to do VMXON. Arguably, init_ia32_feat_ctl() should use setup_clear_cpu_cap() and let KVM figure out a different way to report the misconfigured CPU, but VMX is not the only feature bit that is affected, i.e. there is precedent that tweaking feature bits via {set,clear}_cpu_cap() after ->c_init() is expected to work. Most notably, x86_init_rdrand()'s clearing of X86_FEATURE_RDRAND when RDRAND malfunctions is also overwritten.

[git:media_tree/master] media: venus: cache vb payload to be used by clock scaling

This is an automatic generated email to let you know that the following patch were queued: Subject: media: venus: cache vb payload to be used by clock scaling Author: Stanimir Varbanov <stanimir.varbanov(a)linaro.org> Date: Thu Feb 13 10:55:14 2020 +0100 Instead of iterate over previously queued buffers in clock scaling code do cache the payload in instance context structure for later use when calculating new clock rate.

[RESEND][PATCH] ata: ahci: Add shutdown to freeze hardware resources of ahci

device_shutdown() called from reboot or power_shutdown expect all devices to be shutdown. Same is true for even ahci pci driver.

[PATCH 1/4] PM / Domains: Allow no domain-idle-states DT property in genpd when parsing

by Ulf Hansson

Commit 2c361684803e ("PM / Domains: Don't treat zero found compatible idle states as an error"), moved of_genpd_parse_idle_states() towards allowing none compatible idle state to be found for the device node, rather than returning an error code. However, it didn't consider that the "domain-idle-states" DT property may be missing as it's optional, which makes of_count_phandle_with_args() to return -ENOENT. Let's fix this to make the behaviour consistent.

[PATCH 5.4] io_uring: prevent sq_thread from spinning when it should stop

by Stefano Garzarella

[ Upstream commit 7143b5ac5750f404ff3a594b34fdf3fc2f99f828 ] This patch drops 'cur_mm' before calling cond_resched(), to prevent the sq_thread from spinning even when the user process is finished. Before this patch, if the user process ended without closing the io_uring fd, the sq_thread continues to spin until the 'sq_thread_idle' timeout ends. In the worst case where the 'sq_thread_idle' parameter is bigger than INT_MAX, the sq_thread will spin forever.
