The files in the info directory for MBA are as follows: num_closids The maximum number of CLOSids available for MBA min_bandwidth The minimum memory bandwidth percentage value bandwidth_gran The granularity of the bandwidth control in percent for the particular CPU SKU. Intermediate values entered are rounded off to the previous control step available. Available bandwidth control steps are minimum_bandwidth + N * bandwidth_gran. delay_linear When set, the OS writes a linear percentage based value to the control MSRs ranging from minimum_bandwidth to 100 percent. This value is informational and has no influence on the values written to the schemata files. The values written to the schemata are always bandwidth percentage that is requested.

Cache allocation and memory bandwidth allocation require different information files in the resctrl/info directory, but the current implementation does not allow to have files per resource.

vdso_enabled can be set to arbitrary integer values via the kernel command line 'vdso32=' parameter or via 'sysctl abi.vsyscall32'. load_vdso32() only maps VDSO if vdso_enabled == 1, but ARCH_DLINFO_IA32 merily checks for vdso_enabled != 0. As a consequence the AT_SYSINFO_EHDR auxiliary vector for the VDSO_ENTRY is emitted with a NULL pointer which causes a segfault when the application tries to use the VDSO.

A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

Pull scheduler fixes from Thomas Gleixner: "This update provides: - make the scheduler clock switch to unstable mode smooth so the timestamps stay at microseconds granularity instead of switching to tick granularity. - unbreak perf test tsc by taking the new offset into account which was added in order to proveide better sched clock continuity - switching sched clock to unstable mode runs all clock related computations which affect the sched clock output itself from a work queue. In case of preemption sched clock uses half updated data and provides wrong timestamps. Keep the math in the protected context and delegate only the static key switch to workqueue context. - remove a duplicate header include" * 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/headers: Remove duplicate #include <linux/sched/debug.h> line sched/clock: Fix broken stable to unstable transfer sched/clock, x86/perf: Fix "perf test tsc" sched/clock: Fix clear_sched_clock_stable() preempt wobbly
