2021-04-22usb: dwc3: gadget: Fix START_TRANSFER link state checkThinh Nguyen
The START_TRANSFER command needs to be executed while in ON/U0 link state (with an exception during register initialization). Don't use dwc->link_state to check this since the driver only tracks the link state when the link state change interrupt is enabled. Check the link state from DSTS register instead. Note that often the host already brings the device out of low power before it sends/requests the next transfer. So, the user won't see any issue when the device starts transfer then. This issue is more noticeable in cases when the device delays starting transfer, which can happen during delayed control status after the host put the device in low power.

2021-04-21selinux: add proper NULL termination to the secclass_map permissionsPaul Moore
This patch adds the missing NULL termination to the "bpf" and "perf_event" object class permission lists. This missing NULL termination should really only affect the tools under scripts/selinux, with the most important being genheaders.c, although in practice this has not been an issue on any of my dev/test systems. If the problem were to manifest itself it would likely result in bogus permissions added to the end of the object class; thankfully with no access control checks using these bogus permissions and no policies defining these permissions the impact would likely be limited to some noise about undefined permissions during policy load.

The check is intended to detect whether the E820 memory map provided by the firmware after cold boot unexpectedly differs from the one that was in use when the hibernation image was created. In this case, the hibernation image cannot be restored, as it may cover memory regions that are no longer available to the OS.

2021-04-21brd: expose number of allocated pages in debugfsCalvin Owens
While the maximum size of each ramdisk is defined either as a module parameter, or compile time default, it's impossible to know how many pages have currently been allocated by each ram%d device, since they're allocated when used and never freed. This patch creates a new directory at this location: /sys/kernel/debug/ramdisk_pages/ which will contain a file named "ram%d" for each instantiated ramdisk on the system. The file is read-only, and read() will output the number of pages currently held by that ramdisk. We lose track how much memory a ramdisk is using as pages once used are simply recycled but never freed. In instances where we exhaust the size of the ramdisk with a file that exceeds it, encounter ENOSPC and delete the file for mitigation; df would show decrease in used and increase in available blocks but the since we have touched all pages, the memory footprint of the ramdisk does not reflect the blocks used/available count ...

2021-04-21block: return -EBUSY when there are open partitions in blkdev_reread_partChristoph Hellwig
The switch to go through blkdev_get_by_dev means we now ignore the return value from bdev_disk_changed in __blkdev_get. Add a manual check to restore the old semantics.

2021-04-21spi: Make error handling of gpiod_count() call cleanerAndy Shevchenko
Each time we call spi_get_gpio_descs() the num_chipselect is overwritten either by new value or by the old one. This is an extra operation in case gpiod_count() returns an error. Besides that it slashes the error handling of gpiod_count(). Refactor the code to make error handling of gpiod_count() call cleaner. Note, that gpiod_count() never returns 0, take this into account as well.

This patch fixes identification of DA913x parts by the DA9121 driver, where a lack of clarity lead to implementation on the basis that variant IDs were to be identical to the equivalent rated non-automotive parts. There is a new emphasis on the DT identity to cope with overlap in these ID's - this is not considered to be problematic, because projects would be exclusively using automotive or consumer grade parts.

2021-04-21gpio: omap: Save and restore sysconfigTony Lindgren
As we are using cpu_pm to save and restore context, we must also save and restore the GPIO sysconfig register. This is needed because we are not calling PM runtime functions at all with cpu_pm. We need to save the sysconfig on idle as it's value can get reconfigured by PM runtime and can be different from the init time value. Device specific flags like "ti,no-idle-on-init" can affect the init value.
