Pull power management regression fix from Rafael Wysocki: "Fix problems with switching cpufreq drivers on some x86 systems with ACPI (and with changing the operation modes of the intel_pstate driver on those systems) introduced by recent changes related to the management of frequency limits in cpufreq" * tag 'pm-5.4-final' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: QoS: Invalidate frequency QoS requests after removal

fork: fix pidfd_poll()'s return type

2019-11-20T10:48:50Z

pidfd_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.

PM: QoS: Invalidate frequency QoS requests after removal

2019-11-20T09:46:42Z

Switching cpufreq drivers (or switching operation modes of the intel_pstate driver from "active" to "passive" and vice versa) does not work on some x86 systems with ACPI after commit 3000ce3c52f8 ("cpufreq: Use per-policy frequency QoS"), because the ACPI _PPC and thermal code uses the same frequency QoS request object for a given CPU every time a cpufreq driver is registered and freq_qos_remove_request() does not invalidate the request after removing it from its QoS list, so freq_qos_add_request() complains and fails when that request is passed to it again. Fix the issue by modifying freq_qos_remove_request() to clear the qos and type fields of the frequency request pointed to by its argument after removing it from its QoS list so as to invalidate it. Fixes: 3000ce3c52f8 ("cpufreq: Use per-policy frequency QoS") Reported-and-tested-by: Doug Smythies Signed-off-by: Rafael J. Wysocki Acked-by: Viresh Kumar

uclamp_update_active() should perform the update when p->uclamp[clamp_id].active is true. But when the logic was inverted in [1], the if condition wasn't inverted correctly too.
