2019-11-07block: add zone open, close and finish ioctl supportAjay Joshi
Introduce three new ioctl commands BLKOPENZONE, BLKCLOSEZONE and BLKFINISHZONE to allow applications to control the condition of zones on a zoned block device through the execution of the REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE and REQ_OP_ZONE_FINISH operations.

2019-11-07block: add zone open, close and finish operationsAjay Joshi
Zoned block devices (ZBC and ZAC devices) allow an explicit control over the condition (state) of zones. The operations allowed are: * Open a zone: Transition to open condition to indicate that a zone will actively be written * Close a zone: Transition to closed condition to release the drive resources used for writing to a zone * Finish a zone: Transition an open or closed zone to the full condition to prevent write operations To enable this control for in-kernel zoned block device users, define the new request operations REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE and REQ_OP_ZONE_FINISH as well as the generic function blkdev_zone_mgmt() for submitting these operations on a range of zones. This results in blkdev_reset_zones() removal and replacement with this new zone magement function. Users of blkdev_reset_zones() (f2fs and dm-zoned) are updated accordingly.

2019-11-07block: Simplify REQ_OP_ZONE_RESET_ALL handlingDamien Le Moal
There is no need for the function __blkdev_reset_all_zones() as REQ_OP_ZONE_RESET_ALL can be handled directly in blkdev_reset_zones() bio loop with an early break from the loop.

2019-11-07block: Remove REQ_OP_ZONE_RESET pluggingDamien Le Moal
REQ_OP_ZONE_RESET operations cannot be merged as these bios and requests do not have a size and are never sequential due to the zone start sector position required for their execution. As a result, there is no point in using a plug around blkdev_reset_zones() bio issuing loop. This patch removes this unnecessary plugging.

With the introduction of ZONE_DMA in arm64 we moved the default CMA and crashkernel reservation into that area. This caused a regression on big machines that need big CMA and crashkernel reservations. Note that ZONE_DMA is only 1GB big. Restore the previous behavior as the wide majority of devices are OK with reserving these in ZONE_DMA32. The ones that need them in ZONE_DMA will configure it explicitly.

DMA_SHARED_BUFFER can not be enabled by the user (it represents a library set in the kernel).

2019-11-07pinctrl: stmfx: fix valid_mask init sequenceAmelie Delaunay
With stmfx_pinctrl_gpio_init_valid_mask callback, gpio_valid_mask was used to initialize gpiochip valid_mask for gpiolib. But gpio_valid_mask was not yet initialized. gpio_valid_mask required gpio-ranges to be registered, this is the case after gpiochip_add_data call. But init_valid_mask callback is also called under gpiochip_add_data. gpio_valid_mask initialization cannot be moved before gpiochip_add_data because gpio-ranges are not registered. So, it is not possible to use init_valid_mask callback. To avoid this issue, get rid of valid_mask and rely on ranges.

2019-11-07mtd: spi-nor: Drop spansion_quad_enable()Tudor Ambarus
Drop the default spansion_quad_enable() method and replace it with spansion_read_cr_quad_enable(). The function was buggy, it didn't care about the previous values of the Status and Configuration Registers. spansion_read_cr_quad_enable() is a Read-Modify-Write-Check function that keeps track of what were the previous values of the Status and Configuration Registers. In terms of instruction types sent to the flash, the only difference between the spansion_quad_enable() and spansion_read_cr_quad_enable() is that the later calls spi_nor_read_sr(). We can safely assume that all flashes support spi_nor_read_sr(), because all flashes call it in spi_nor_sr_ready(). The transition from spansion_quad_enable() to spansion_read_cr_quad_enable() will not affect anybody, drop the buggy code.

2019-11-06io_uring: Use submit info inlined into reqPavel Begunkov
Stack allocated struct sqe_submit is passed down to the submission path along with a request (a.k.a. struct io_kiocb), and will be copied into req->submit for async requests. As space for it is already allocated, fill req->submit in the first place instead of using on-stack one. As a result: 1. sqe->submit is the only place for sqe_submit and is always valid, so we don't need to track which one to use. 2. don't need to copy in case of async 3. allows to simplify the code by not carrying it as an argument all the way down 4. allows to reduce number of function arguments / potentially improve spilling The downside is that stack is most probably be cached, that's not true for just allocated memory for a request. Another concern is cache pollution. Though, a request would be touched and fetched along with req->submit at some point anyway, so shouldn't be a problem.
