Pull power management fixes from Rafael Wysocki: "One of these is an intel_pstate regression fix and it is not a small change, but it mostly removes code that shouldn't be there. That code was acquired by mistake and has been a source of constant pain since then, so the time has come to get rid of it finally. We have not seen problems with this change in the lab, so fingers crossed. The rest is more usual: one more intel_pstate commit removing useless code, a cpufreq core fix to make it restore policy limits on CPU online (which prevents the limits from being reset over system suspend/resume), a schedutil cpufreq governor initialization fix to make it actually work as advertised on all systems and an extra sanity check in the cpuidle core to prevent crashes from happening if the arch code messes things up. Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode

This was broken in commit cd979883 ("xen/acpi-processor: fix enabling interrupts on syscore_resume"). do_suspend (from xen/manage.c) and thus xen_resume_notifier never get called on the initial-domain at resume (it is if running as guest.) The rationale for the breaking change was that upload_pm_data() potentially does blocking work in syscore_resume(). This patch addresses the original issue by scheduling upload_pm_data() to execute in workqueue context.

Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting.

icsk_ack.lrcvtime has a 0 value at socket creation time. tcpi_last_data_recv can have bogus value if no payload is ever received. This patch initializes icsk_ack.lrcvtime for active sessions in tcp_finish_connect(), and for passive sessions in tcp_create_openreq_child() Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
