14e3e98 | Linus Torvalds | 27 December 2020, 18:56:33 UTC | proc mountinfo: make splice available again Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link. With this, the initialization ordering is restored to match the prior sequence.

These shell arguments mostly comprise flags that have been set in the Makefile. However, when coccicheck is specified in the make command as a rule, the number of shell arguments is zero, thus passing the invalid value -1 to the shift command, resulting in an error. Modify coccicheck to print correct usage of make coccicheck so as to avoid the error.

614cb58 | Linus Torvalds | 22 December 2020, 22:19:21 UTC | Merge tag 'acpi-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI updates from Rafael Wysocki: "These make the ACPI enumeration of devices take _DEP information into account more aggressively, fix device IDs matching in the ACPI part of the PNP devices framework and update the ACPI code related to suspend-to-idle to take systems based on AMD hardware into account properly. Specifics: - Modify the ACPI device enumeration code to defer the enumeration of devices with an _HID whose lists of operation region dependencies returned by _DEP are not empty after eliminating the entries representing known-benign dependencies from them (Rafael Wysocki, Hans de Goede). - Make the ACPI PNP code mathing device IDs also take the length of the given ID string into account (Hui Wang). - Add AMD systems support to the ACPI code handling suspend-to-idle via the PNP0D80 (System Power Management Controller) device _DSM interface (Shyam Sundar). - Move the suspend-to-idle handling code related to the PNP0D80 device _DSM interface, which is x86-specific, to a separate file in the x86/ subdirectory (Rafael Wysocki)" * tag 'acpi-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: PM: s2idle: Move x86-specific code to the x86 directory ACPI: scan: Add Intel Baytrail Mailbox Device to acpi_ignore_dep_ids ACPI: scan: Avoid unnecessary second pass in acpi_bus_scan() ACPI: scan: Defer enumeration of devices with _DEP lists ACPI: scan: Evaluate _DEP before adding the device ACPI: PM: s2idle: Add AMD support to handle _DSM ACPI: PNP: compare the string length in the matching_id() | 22 December 2020, 22:19:21 UTC |

Specifics: - Rework the passive-mode "fast switch" path in the intel_pstate driver to allow it receive the minimum (required) and target (desired) performance information from the schedutil governor so as to avoid running some workloads too fast (Rafael Wysocki). - Make the intel_pstate driver allow the policy max limit to be increased after the guaranteed performance value for the given CPU has increased (Rafael Wysocki). - Clean up the handling of CPU coordination types in the CPPC cpufreq driver and make it export frequency domains information to user space via sysfs (Ionela Voinescu). - Fix the ACPI code handling processor objects to use a correct coordination type when it fails to map frequency domains and drop a redundant CPU map initialization from it (Ionela Voinescu, Punit Agrawal)" * tag 'pm-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: intel_pstate: Use most recent guaranteed performance values cpufreq: intel_pstate: Implement the ->adjust_perf() callback cpufreq: Add special-purpose fast-switching callback for drivers cpufreq: schedutil: Add util to struct sg_cpu cppc_cpufreq: replace per-cpu data array with a list cppc_cpufreq: expose information on frequency domains cppc_cpufreq: clarify support for coordination types cppc_cpufreq: use policy->cpu as driver of frequency setting ACPI: processor: fix NONE coordination for domain mapping failure | 22 December 2020, 22:12:10 UTC |
