2021-08-24mmc: block: Support alternative_gpt_sector() operationDmitry Osipenko4-0/+60
Support generic alternative_gpt_sector() block device operation. It calculates location of GPT entry for eMMC of NVIDIA Tegra Android devices. Add new MMC_CAP2_ALT_GPT_TEGRA flag that enables scanning of alternative GPT sector and add raw_boot_mult field to mmc_ext_csd which allows to get size of the boot partitions that is needed for the calculation.

2021-08-09dm: delay registering the gendiskChristoph Hellwig2-13/+11
device mapper is currently the only outlier that tries to call register_disk after add_disk, leading to fairly inconsistent state of these block layer data structures. Instead change device-mapper to just register the gendisk later now that the holder mechanism can cope with that.

2021-08-05loop: Select I/O scheduler 'none' from inside add_disk()Bart Van Assche1-1/+2
We noticed that the user interface of Android devices becomes very slow under memory pressure. This is because Android uses the zram driver on top of the loop driver for swapping, because under memory pressure the swap code alternates reads and writes quickly, because mq-deadline is the default scheduler for loop devices and because mq-deadline delays writes by five seconds for such a workload with default settings. Fix this by making the kernel select I/O scheduler 'none' from inside add_disk() for loop devices. This default can be overridden at any time from user space, e.g. via a udev rule. This approach has an advantage compared to changing the I/O scheduler from userspace from 'mq-deadline' into 'none', namely that synchronize_rcu() does not get called. This patch changes the default I/O scheduler for loop devices from 'mq-deadline' into 'none'. Additionally, this patch reduces the Android boot time on my test setup with 0.5 seconds compared to configuring the loop I/O scheduler from user space.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI fixes from Rafael Wysocki: "These revert a recent IRQ resources handling modification that turned out to be problematic, fix suspend-to-idle handling on AMD platforms to take upcoming systems into account properly and fix the retrieval of the DPTF attributes of the PCH FIVR. Specifics: - Revert recent change of the ACPI IRQ resources handling that attempted to improve the ACPI IRQ override selection logic, but introduced serious regressions on some systems (Hui Wang). - Fix up quirks for AMD platforms in the suspend-to-idle support code so as to take upcoming systems using uPEP HID AMDI007 into account as appropriate (Mario Limonciello). - Fix the code retrieving DPTF attributes of the PCH FIVR so that it agrees on the return data type with the ACPI control method evaluated for this purpose (Srinivas Pandruvada)" * tag 'acpi-5.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: DPTF: Fix reading of attributes Revert "ACPI: resources: Add checks for ACPI IRQ override" ACPI: PM: Add support for upcoming AMD uPEP HID AMDI007

2021-07-30can: esd_usb2: fix memory leakPavel Skripkin1-1/+15
In esd_usb2_setup_rx_urbs() MAX_RX_URBS coherent buffers are allocated and there is nothing, that frees them: 1) In callback function the urb is resubmitted and that's all 2) In disconnect function urbs are simply killed, but URB_FREE_BUFFER is not set (see esd_usb2_setup_rx_urbs) and this flag cannot be used with coherent buffers. So, all allocated buffers should be freed with usb_free_coherent() explicitly. Side note: This code looks like a copy-paste of other can drivers. The same patch was applied to mcba_usb driver and it works nice with real hardware. There is no change in functionality, only clean-up code for coherent buffers.
