[PATCH] mtd: rawnand: ingenic: Fix ingenic_ecc dependency

by Paul Cercueil

If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m, which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails: drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove': ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release' drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct': ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct' To fix that, the ingenic_nand and ingenic_ecc modules have been fused into one single module. - The ingenic_ecc.c code is now compiled in only if $(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead of tristate. - To avoid changing the module name, the ingenic_nand.c file is moved to ingenic_nand_drv.c. Then the module name is still ingenic_nand. - Since ingenic_ecc.c is no more a module, the module-specific macros have been dropped, and the functions are no more exported for use by the ingenic_nand driver.

[PATCH v2] dmaengine: imx-sdma: remove BD_INTR for channel0

by yibin.gong＠nxp.com

From: Robin Gong <yibin.gong(a)nxp.com> It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa3c78 ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case.

[PATCH] filesystem-dax: Disable PMD support

by Dan Williams

Ever since the conversion of DAX to the Xarray a RocksDB benchmark has been encountering intermittent lockups. The backtraces always include the filesystem-DAX PMD path, multi-order entries have been a source of bugs in the past, and disabling the PMD path allows a test that fails in minutes to run for an hour. The regression has been bisected to "dax: Convert page fault handlers to XArray", but little progress has been made on the root cause debug. Unless / until root cause can be identified mark CONFIG_FS_DAX_PMD broken to preclude intermittent lockups. Reverting the Xarray conversion also works, but that change is too big to backport. The implementation is committed to Xarray at this point.

[4.19.y PATCH 1/2] block: Fix a NULL pointer dereference in generic_make_request()

by Guilherme G. Piccoli

----------------------------------------------------------------- This patch is not on mainline and is meant to 4.19 stable *only*. After the patch description there's a reasoning about that. ----------------------------------------------------------------- Commit 37f9579f4c31 ("blk-mq: Avoid that submitting a bio concurrently with device removal triggers a crash") introduced a NULL pointer dereference in generic_make_request(). The patch sets q to NULL and enter_succeeded to false; right after, there's an 'if (enter_succeeded)' which is not taken, and then the 'else' will dereference q in blk_queue_dying(q). This patch just moves the 'q = NULL' to a point in which it won't trigger the oops, although the semantics of this NULLification remains untouched. A simple test case/reproducer is as follows: a) Build kernel v4.19.56-stable with CONFIG_BLK_CGROUP=n. b) Create a raid0 md array with 2 NVMe devices as members, and mount it with an ext4 filesystem. c) Run the following oneliner (supposing the raid0 is mounted in /mnt): (dd of=/mnt/tmp if=/dev/zero bs=1M count=999 &); sleep 0.3; echo 1 > /sys/block/nvme1n1/device/device/remove (whereas nvme1n1 is the 2nd array member) This will trigger the following oops: BUG: unable to handle kernel NULL pointer dereference at 0000000000000078 PGD 0 P4D 0 Oops: 0000 [#1] SMP PTI RIP: 0010:generic_make_request+0x32b/0x400 Call Trace: submit_bio+0x73/0x140 ext4_io_submit+0x4d/0x60 ext4_writepages+0x626/0xe90 do_writepages+0x4b/0xe0 [...] This patch has no functional changes and preserves the md/raid0 behavior when a member is removed before kernel v4.17. ---------------------------- Why this is not on mainline? ---------------------------- The patch was originally submitted upstream in linux-raid and linux-block mailing-lists - it was initially accepted by Song Liu, but Christoph Hellwig[0] observed that there was a clean-up series ready to be accepted from Ming Lei[1] that fixed the same issue. The accepted patches from Ming's series in upstream are: commit 47cdee29ef9d ("block: move blk_exit_queue into __blk_release_queue") and commit fe2008640ae3 ("block: don't protect generic_make_request_checks with blk_queue_enter"). Those patches basically do a clean-up in the block layer involving: 1) Putting back blk_exit_queue() logic into __blk_release_queue(); that path was changed in the past and the logic from blk_exit_queue() was added to blk_cleanup_queue(). 2) Removing the guard/protection in generic_make_request_checks() with blk_queue_enter(). The problem with Ming's series for -stable is that it relies in the legacy request IO path removal. So it's "backport-able" to v5.0+, but doing that for early versions (like 4.19) would incur in complex code changes. Hence, it was suggested by Christoph and Song Liu that this patch was submitted to stable only; otherwise merging it upstream would add code to fix a path removed in a subsequent commit.

[PATCH] usb: dwc2: use a longer AHB idle timeout in dwc2_core_reset()

by Martin Blumenstingl

Use a 10000us AHB idle timeout in dwc2_core_reset() and make it consistent with the other "wait for AHB master IDLE state" ocurrences. This fixes a problem for me where dwc2 would not want to initialize when updating to 4.19 on a MIPS Lantiq VRX200 SoC. dwc2 worked fine with 4.14. Testing on my board shows that it takes 180us until AHB master IDLE state is signalled. The very old vendor driver for this SoC (ifxhcd) used a 1 second timeout. Use the same timeout that is used everywhere when polling for GRSTCTL_AHBIDLE instead of using a timeout that "works for one board" (180us in my case) to have consistent behavior across the dwc2 driver.

[PATCH 1/2] regulator: s2mps11: Fix buck7 and buck8 wrong voltages

by Krzysztof Kozlowski

On S2MPS11 device, the buck7 and buck8 regulator voltages start at 750 mV, not 600 mV. Using wrong minimal value caused shifting of these regulator values by 150 mV (e.g. buck7 usually configured to v1.35 V was reported as 1.2 V). On most of the boards these regulators are left in default state so this was only affecting reported voltage. However if any driver wanted to change them, then effectively it would set voltage 150 mV higher than intended.
