2019-03-26staging: erofs: fix error handling when failed to read compresssed dataGao Xiang
Complete read error handling paths for all three kinds of compressed pages: 1) For cache-managed pages, PG_uptodate will be checked since read_endio will unlock and SetPageUptodate for these pages; 2) For inplaced pages, read_endio cannot SetPageUptodate directly since it should be used to mark the final decompressed data, PG_error will be set with page locked for IO error instead; 3) For staging pages, PG_error is used, which is similar to what we do for inplaced pages.

2019-03-26staging: vt6655: Fix interrupt race condition on device start up.Malcolm Priestley
It appears on some slower systems that the driver can find its way out of the workqueue while the interrupt is disabled by continuous polling by it. Move MACvIntEnable to vnt_interrupt_work so that it is always enabled on all routes out of vnt_interrupt_process. Move MACvIntDisable so that the device doesn't keep polling the system while the workqueue is being processed.

2019-03-25ARM: dts: sunxi: Add default dr_modeMaxime Ripard
The USB OTG binding we have mandates to have a dr_mode property, yet not all boards are setting it. Since the generic otg binding states that the default mode should be the OTG mode, let's use that one in our DTSI.

2019-03-25sbitmap: order READ/WRITE freed instance and setting clear bitMing Lei
Inside sbitmap_queue_clear(), once the clear bit is set, it will be visiable to allocation path immediately. Meantime READ/WRITE on old associated instance(such as request in case of blk-mq) may be out-of-order with the setting clear bit, so race with re-allocation may be triggered. Adds one memory barrier for ordering READ/WRITE of the freed associated instance with setting clear bit for avoiding race with re-allocation.

2019-03-25blk-mq: fix sbitmap ws_active for shared tagsJens Axboe
We now wrap sbitmap waitqueues in an active counter, so we can avoid iterating wakeups unless we have waiters there. This works as long as everyone that's manipulating the waitqueues use the proper helpers. For the tag wait case for shared tags, however, we add ourselves to the waitqueue without incrementing/decrementing the ->ws_active count. This means that wakeups can take a long time to happen. Fix this by manually doing the inc/dec as needed for the wait queue handling.

2019-03-25arm64: tegra: Disable CQE Support for SDMMC4 on Tegra186Jonathan Hunter
Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression that is causing accesses to the file-system on the eMMC to fail. Errors such as the following have been observed ... mmc2: running CQE recovery mmc2: mmc_select_hs400 failed, error -110 print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700 mmc2: cqhci: CQE failed to exit halt state For now disable CQE support for Tegra186 until this issue is resolved.

2019-03-25io_uring: fix big-endian compat signal mask handlingArnd Bergmann
On big-endian architectures, the signal masks are differnet between 32-bit and 64-bit tasks, so we have to use a different function for reading them from user space. io_cqring_wait() initially got this wrong, and always interprets this as a native structure. This is ok on x86 and most arm64, but not on s390, ppc64be, mips64be, sparc64 and parisc. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
