[PATCH 1/3] pinctrl: mcp23s08: fix debugfs entry for mcp23s18 device

by Marco Felsch

This patch fixes 'commit 9b3e4207661e ("pinctrl: mcp23s08: spi: Fix regmap debugfs entries")'. For sure the MCP23S18 device has only 1 address pin but this will get decoded into three internally ([1], section 1.4).

[iw_cxgb4 linux-4.9.y] iw_cxgb4: only allow 1 flush on user qps

commit 308aa2b8f7b7db3332a7d41099fd37851fb793b2 upstream Once the qp has been flushed, it cannot be flushed again. The user qp flush logic wasn't enforcing it however.

[PATCH 4.4.y 0/2] HID: sony: backport DualShock 4 device ids

by Roderick Colenbrander

Hi, We would like to request inclusion of updated DualShock 4 device ids for hid-sony in Linux 4.4. Existing devices on older kernels already support the original DualShock 4, but not recent hardware revisions. A similar backport was submitted for 3.18/4.9. Kernels newer than 4.12 already include these patches. The patches were cherry-picked from upstream and modified to apply cleanly and compile.

[PATCH stable] tick/nohz: Prevent bogus softirq pending warning

by Thomas Gleixner

Commit 0a0e0829f990 ("nohz: Fix missing tick reprogram when interrupting an inline softirq") got backported to stable trees and now causes the NOHZ softirq pending warning to trigger. It's not an upstream issue as the NOHZ update logic has been changed there. The problem is when a softirq disabled section gets interrupted and on return from interrupt the tick/nohz state is evaluated, which then can observe pending soft interrupts. These soft interrupts are legitimately pending because they cannot be processed as long as soft interrupts are disabled and the interrupted code will correctly process them when soft interrupts are reenabled. Add a check for softirqs disabled to the pending check to prevent the warning.

[PATCH 02/10] MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3

by Huacai Chen

For multi-node Loongson-3 (NUMA configuration), r4k_blast_scache() can only flush Node-0's scache. So we add r4k_blast_scache_node() by using (CAC_BASE | (node_id << NODE_ADDRSPACE_SHIFT)) instead of CKSEG0 as the start address.

[PATCH v3] block: fix deadline elevator drain for zoned block devices

by Damien Le Moal

When the deadline scheduler is used with a zoned block device, writes to a zone will be dispatched one at a time. This causes the warning message: deadline: forced dispatching is broken (nr_sorted=X), please report this to be displayed when switching to another elevator with the legacy I/O path while write requests to a zone are being retained in the scheduler queue. Prevent this message from being displayed when executing elv_drain_elevator() for a zoned block device. __blk_drain_queue() will loop until all writes are dispatched and completed, resulting in the desired elevator queue drain without extensive modifications to the deadline code itself to handle forced-dispatch calls.
