Use separate functions for the device core to bring a CPU up and down. Users outside the device core must use add/remove_cpu() which will take care of extra housekeeping work like keeping sysfs in sync.

2020-03-25ACPI: PM: s2idle: Refine active GPEs checkRafael J. Wysocki
The check for any active GPEs added by commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") turns out to be insufficiently precise to prevent some systems from resuming prematurely due to a spurious EC wakeup, so refine it by first checking if any GPEs other than the EC GPE are active and skipping all of the SCIs coming from the EC that do not produce any genuine wakeup events after processing.

2020-03-25ACPICA: Allow acpi_any_gpe_status_set() to skip one GPERafael J. Wysocki
The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring. For this reason, redefine acpi_any_gpe_status_set() to take the number of a GPE to skip as an argument.

2020-03-25gpio: mmio: introduce BGPIOF_NO_SET_ON_INPUTChuanhong Guo
Some gpio controllers ignores pin value writing when that pin is configured as input mode. As a result, bgpio_dir_out should set pin to output before configuring pin values or gpio pin values can't be set up properly. Introduce two variants of bgpio_dir_out: bgpio_dir_out_val_first and bgpio_dir_out_dir_first, and assign direction_output according to a new flag: BGPIOF_NO_SET_ON_INPUT.

2020-03-25gpio: pl061: Warn when IRQ line has not been configuredAlexander Sverdlin
Existing (irq < 0) condition is always false because adev->irq has unsigned type and contains 0 in case of failed irq_of_parse_and_map(). Up to now all the mapping errors were silently ignored. Seems that repairing this check would be backwards-incompatible and might break the probe() for the implementations without IRQ support. Therefore warn the user instead.

2020-03-24scsi: sd: Fix optimal I/O size for devices that change reported valuesMartin K. Petersen
Some USB bridge devices will return a default set of characteristics during initialization. And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.
