2020-12-30kernel/io_uring: cancel io_uring before task worksPavel Begunkov2-2/+2
For cancelling io_uring requests it needs either to be able to run currently enqueued task_works or having it shut down by that moment. Otherwise io_uring_cancel_files() may be waiting for requests that won't ever complete.

2020-12-30intel_idle: add SnowRidge C-state tableArtem Bityutskiy1-1/+40
Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville platforms. The following has been changed. 1. C1E latency changed from 10us to 15us. It was measured using the open source "wult" tool (the "nic" method, 15us is the 99.99th percentile). 2. C1E power break even changed from 20us to 25us, which may result in less C1E residency in some workloads. 3. C6 latency changed from 50us to 130us. Measured the same way as C1E. The C6 C-state is supported only by some SnowRidge revisions, so add a C-state table commentary about this. On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even though C6 is present in the table, the driver will only use it if the CPU does support it.

2020-12-30cpufreq: intel_pstate: Fix fast-switch fallback pathRafael J. Wysocki1-1/+0
When sugov_update_single_perf() falls back to the "frequency" path due to the missing scale-invariance, it will call cpufreq_driver_fast_switch() via sugov_fast_switch() and the driver's ->fast_switch() callback will be invoked, so it must not be NULL. However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to NULL when it is going to use intel_cpufreq_adjust_perf(), which is a mistake, because on x86 the scale-invariance may be turned off dynamically, so modify it to retain the original ->adjust_perf() callback pointer.

2020-12-29mm: slub: call account_slab_page() after slab page initializationRoman Gushchin1-3/+2
It's convenient to have page->objects initialized before calling into account_slab_page(). In particular, this information can be used to pre-alloc the obj_cgroup vector. Let's call account_slab_page() a bit later, after the initialization of page->objects. This commit doesn't bring any functional change, but is required for further optimizations.
