Furthermore, this register is part of the GT forcewake domain rather than the RENDER domain, so it should not be impacted by RCS engine resets.

Pull kvm fixes from Paolo Bonzini: "Certain AMD processors are vulnerable to a cross-thread return address predictions bug. When running in SMT mode and one of the sibling threads transitions out of C0 state, the other thread gets access to twice as many entries in the RSB, but unfortunately the predictions of the now-halted logical processor are not purged. Therefore, the executing processor could speculatively execute from locations that the now-halted processor had trained the RSB on. The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB when context switching to the idle thread. However, KVM allows a VMM to prevent exiting guest mode when transitioning out of C0 using the KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change this behavior. To mitigate the cross-thread return address predictions bug, a VMM must not be allowed to override the default behavior to intercept C0 transitions. These patches introduce a KVM module parameter that, if set, will prevent the user from disabling the HLT, MWAIT and CSTATE exits" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: Documentation/hw-vuln: Add documentation for Cross-Thread Return Predictions KVM: x86: Mitigate the cross-thread return address predictions bug x86/speculation: Identify processors vulnerable to SMT RSB predictions
2023-02-14EDAC/amd64: Shut up an -Werror,-Wsometimes-uninitialized clang false positiveYazen Ghannam
Reportedly, clang cannot do interprocedural analysis: https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org and see that those arguments won't be used uninitialized. So, yeah, the code's fine even without this. Normally, such a "fix" won't be applied but that warning gets automatically enabled in -Wall builds and when CONFIG_WERROR is set in allmodconfig builds, the build fails. So shut it up with a minimal fix as this code will see more reorganization very soon.

2023-02-14alarmtimer: Prevent starvation by small intervals and SIG_IGNThomas Gleixner
syzbot reported a RCU stall which is caused by setting up an alarmtimer with a very small interval and ignoring the signal. The reproducer arms the alarm timer with a relative expiry of 8ns and an interval of 9ns. Not a problem per se, but that's an issue when the signal is ignored because then the timer is immediately rearmed because there is no way to delay that rearming to the signal delivery path. See posix_timer_fn() and commit 58229a189942 ("posix-timers: Prevent softirq starvation by small intervals and SIG_IGN") for details. The reproducer does not set SIG_IGN explicitely, but it sets up the timers signal with SIGCONT. That has the same effect as explicitely setting SIG_IGN for a signal as SIGCONT is ignored if there is no handler set and the task is not ptraced. The log clearly shows that: [pid 5102] --- SIGCONT {si_signo=SIGCONT, si_code=SI_TIMER, si_timerid=0, si_overrun=316014, si_int=0, si_ptr=NULL} --- It works because the tasks are traced and therefore the signal is queued so the tracer can see it, which delays the restart of the timer to the signal delivery path. But then the tracer is killed: [pid 5087] kill(-5102, SIGKILL <unfinished ...> ... ./strace-static-x86_64: Process 5107 detached and after it's gone the stall can be observed: syzkaller login: [ 79.439102][ C0] hrtimer: interrupt took 68471 ns [ 184.460538][ C1] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: ...

That's accurate vs. the overrun accounting, but slightly inaccurate vs. timer_gettimer(2). The comment in that function says what needs to be done and there was a fix available for the regular userspace induced SIG_IGN mechanism, but that did not work due to the implicit ignore for SIGCONT and similar signals. This needs to be worked on, but for now the only available workaround is to do exactly what posix_timer_fn() does: Increase the interval of self-rearming timers, which have their signal ignored, to at least a jiffie. Interestingly this has been fixed before via commit ff86bf0c65f1 ("alarmtimer: Rate limit periodic intervals") already, but that fix got lost in a later rework.

2023-02-14dt-bindings: cpufreq: qcom-cpufreq-nvmem: make cpr bindings optionalChristian Marangi
The qcom-cpufreq-nvmem driver supports 2 kind of devices: - pre-cpr that doesn't have power-domains and base everything on nvmem cells and multiple named microvolt bindings. Doesn't need required-opp binding in the opp nodes as they are only used for genpd based devices. - cpr-based that require power-domain in the cpu nodes and use various source to decide the correct voltage and freq Require required-opp binding since they need to be linked to the related opp-level. When the schema was introduced, it was wrongly set to always require these binding but this is not the case for pre-cpr devices. Make the power-domain and the required-opp optional and set them required only for qcs404 based devices.

2023-02-13net: stmmac: fix order of dwmac5 FlexPPS parametrization sequenceJohannes Zink
So far changing the period by just setting new period values while running did not work. The order as indicated by the publicly available reference manual of the i.MX8MP [1] indicates a sequence: * initiate the programming sequence * set the values for PPS period and start time * start the pulse train generation. This is currently not used in dwmac5_flex_pps_config(), which instead does: * initiate the programming sequence and immediately start the pulse train generation * set the values for PPS period and start time This caused the period values written not to take effect until the FlexPPS output was disabled and re-enabled again. This patch fix the order and allows the period to be set immediately.

Mark the Tiger Lake UP{3,4} AHCI controller as "low_power". This enables S0ix to work out of the box. Otherwise this isn't working unless the user manually sets /sys/class/scsi_host/*/link_power_management_policy. Intel lists a total of 4 SATA controller IDs in [1] for those mobile PCHs. This commit just adds the "AHCI" variant since I only tested those.

If mmc_add_host() fails, it doesn't need to call mmc_remove_host(), or it will cause null-ptr-deref, because of deleting a not added device in mmc_remove_host(). To fix this, goto label 'fail_glue_init', if mmc_add_host() fails, and change the label 'fail_add_host' to 'fail_gpiod_request'.

2023-02-14mmc: sdio: fix possible resource leaks in some error pathsYang Yingliang
If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can not release the resources, because the sdio function is not presented in these two cases, it won't call of_node_put() or put_device(). To fix these leaks, make sdio_func_present() only control whether device_del() needs to be called or not, then always call of_node_put() and put_device(). In error case in sdio_init_func(), the reference of 'card->dev' is not get, to avoid redundant put in sdio_free_func_cis(), move the get_device() to sdio_alloc_func() and put_device() to sdio_release_func(), it can keep the get/put function be balanced. Without this patch, while doing fault inject test, it can get the following leak reports, after this fix, the leak is gone. unreferenced object 0xffff888112514000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741614 (age 124.774s) hex dump (first 32 bytes): 00 e0 6f 12 81 88 ff ff 60 58 8d 06 81 88 ff ff ..o.....`X...... 10 40 51 12 81 88 ff ff 10 40 51 12 81 88 ff ff .@Q......@Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<000000002f839ccb>] mmc_alloc_card+0x38/0xb0 [mmc_core] [<0000000004adcbf6>] mmc_sdio_init_card+0xde/0x170 [mmc_core] [<000000007538fea0>] mmc_attach_sdio+0xcb/0x1b0 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core] unreferenced object 0xffff888112511000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741623 (age 124.766s) hex dump (first 32 bytes): 00 40 51 12 81 88 ff ff e0 58 8d 06 81 88 ff ff .@Q......X...... 10 10 51 12 81 88 ff ff 10 10 51 12 81 88 ff ff ..Q.......Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<00000000fcbe706c>] sdio_alloc_func+0x35/0x100 [mmc_core] [<00000000c68f4b50>] mmc_attach_sdio.cold.18+0xb1/0x395 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core] Fixes: 3d10a1ba0d37 ("sdio: fix reference counting in sdio_remove_func()") Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20230130125808.3471254-1-yangyingliang@huawei.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
