2020-07-30ASoC: soc-core: Fix regression causing sysfs entries to disappearCharles Keepax
The allocation order of things in soc_new_pcm_runtime was changed to move the device_register before the allocation of the rtd structure. This was to allow the rtd allocation to be managed by devm. However currently the sysfs entries are added by device_register and their visibility depends on variables within the rtd structure, this causes the pmdown_time and dapm_widgets sysfs entries to be missing for all rtds. Correct this issue by manually calling device_add_groups after the appropriate information is available.

2020-07-30tasklet: Introduce new initialization APIRomain Perier
Nowadays, modern kernel subsystems that use callbacks pass the data structure associated with a given callback as argument to the callback. The tasklet subsystem remains one which passes an arbitrary unsigned long to the callback function. This has several problems: - This keeps an extra field for storing the argument in each tasklet data structure, it bloats the tasklet_struct structure with a redundant .data field - No type checking can be performed on this argument. Instead of using container_of() like other callback subsystems, it forces callbacks to do explicit type cast of the unsigned long argument into the required object type. - Buffer overflows can overwrite the .func and the .data field, so an attacker can easily overwrite the function and its first argument to whatever it wants. Add a new tasklet initialization API, via DECLARE_TASKLET() and tasklet_setup(), which will replace the existing ones. This work is greatly inspired by the timer_struct conversion series, see commit e99e88a9d2b0 ("treewide: setup_timer() -> timer_setup()") To avoid problems with both -Wcast-function-type (which is enabled in the kernel via -Wextra is several subsystems), and with mismatched function prototypes when build with Control Flow Integrity enabled, this adds the "use_callback" member to let the tasklet caller choose which union member to call through. Once all old API uses are removed, this and the .data member will be removed as well. (On 64-bit this does not grow the struct size as the new member fills the hole after atomic_t, which is also "int" sized.)

2020-07-30e100: use generic power managementVaibhav Gupta
With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let PCI core handle the work. e100_suspend() calls __e100_shutdown() to perform intermediate tasks. __e100_shutdown() calls pci_save_state() which is not recommended. e100_suspend() also calls __e100_power_off() which is calling PCI helper functions, pci_prepare_to_sleep(), pci_set_power_state(), along with pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is disabled as earlier using device_wakeup_disable(). Compile-tested only.

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux Pull devfreq updates for v5.9 from Chanwoo Choi: 1. Update devfreq core - Add delayed timer support for polling mode. Until now, devfreq supported only deferrable timer to avoid unneeded CPU wakeups. However, it has a problem for non-CPU devices, like DMC, doing DMA. Such devices need to monitor continuously regardless of the CPU state, so delayed timer support for the polling mode to facilitate the continuous monitoring. - Fix indentation of result of devfreq_summary debugfs node. - Fix the wrong end of code with a semicolon instead of a comma. - Clean-up code to use a unified local variable name in sysfs-related internal funcitons. - Fix trivial spelling mistake in devfreq-event.c. 2. Update devfreq drivers - Add the exception handling code to control when rockchip,pmu property is absent for rk3399_dmc.c. - Add missing 'rockchip,pmu' property to dt-binding document for rk3399_dmc.c. - Change the type of timer in exynos5422-dmc.c from deferrable to delayed in order to monitor the DMC (Dynamic Memory Controller) status regardless of the CPU idle state. Also adjust the polling interval and upthreshold value in order to react faster and make better decisions when benchmarking testing for the memory behavior. - Add module parameter to either enable or disable the IRQ mode for DMC behavior monitoring. exynos5422-dmc.c can operate in both the polling and the IRQ mode. The user can choose the monitoring mode via a module param. The default monitoring mode is the polling mode with a delayed timer. 3. Add maintainer entry - Add Dmitry Osipenko <digetx@gmail.com> as maintainer for memory frequency scaling drivers for Nvidia Tegra.

2020-07-30cpufreq: intel_pstate: Fix EPP setting via sysfs in active modeRafael J. Wysocki
Because intel_pstate_set_energy_pref_index() reads and writes the MSR_HWP_REQUEST register without using the cached value of it used by intel_pstate_hwp_boost_up() and intel_pstate_hwp_boost_down(), those functions may overwrite the value written by it and so the EPP value set via sysfs may be lost. To avoid that, make intel_pstate_set_energy_pref_index() take the cached value of MSR_HWP_REQUEST just like the other two routines mentioned above and update it with the new EPP value coming from user space in addition to updating the MSR. Note that the MSR itself still needs to be updated too in case hwp_boost is unset or the boosting mechanism is not active at the EPP change time.

2020-07-30cpufreq: intel_pstate: Rearrange the storing of new EPP valuesRafael J. Wysocki
Move the locking away from intel_pstate_set_energy_pref_index() into its only caller and drop the (now redundant) return_pref label from it. Also move the "raw" EPP value check into the caller of that function, so as to do it before acquiring the mutex, and reduce code duplication related to the "raw" EPP values processing somewhat. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Francisco Jerez <currojerez@riseup.net>
2020-07-30random: fix circular include dependency on arm64 after addition of percpu.hWilly Tarreau
Daniel Díaz and Kees Cook independently reported that commit f227e3ec3b5c ("random32: update the net random state on interrupt and activity") broke arm64 due to a circular dependency on include files since the addition of percpu.h in random.h. The correct fix would definitely be to move all the prandom32 stuff out of random.h but for backporting, a smaller solution is preferred. This one replaces linux/percpu.h with asm/percpu.h, and this fixes the problem on x86_64, arm64, arm, and mips. Note that moving percpu.h around didn't change anything and that removing it entirely broke differently. When backporting, such options might still be considered if this patch fails to help. [ It turns out that an alternate fix seems to be to just remove the troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h> that causes the circular dependency. But we might as well do the whole belt-and-suspenders thing, and minimize inclusion in <linux/random.h> too. Either will fix the problem, and both are good changes. - Linus ] Reported-by: Daniel Díaz <daniel.diaz@linaro.org> Reported-by: Kees Cook <keescook@chromium.org> Tested-by: Marc Zyngier <maz@kernel.org> Fixes: f227e3ec3b5c Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
