[PATCH v2 4/5] genirq: Initialize resend_node hlist for all irq_desc

by Dawei Li

For !CONFIG_SPARSE_IRQ kernel, early_irq_init() is supposed to initialize all the desc entries in system, desc->resend_node included. Thus, initialize desc->resend_node for all irq_desc entries, rather than irq_desc[0] only, which is the current implementation is about.

[PATCH net v1] net: dsa: mv88e6xxx: Make unsupported C45 reads return 0xffff

by Andrew Lunn

When there is no device on the bus for a given address, the pull up resistor on the data line results in the read returning 0xffff. The phylib core code understands this when scanning for devices on the bus, and a number of MDIO bus masters make use of this as a way to indicate they cannot perform the read. Make us of this as a minimal fix for stable where the mv88e6xxx returns EOPNOTSUPP when the hardware does not support C45, but phylib interprets this as a fatal error, which it should not be.

[PATCH 1/3] net: stmmac: do not clear TBS enable bit on link up/down

by Esben Haabendal

With the dma conf being reallocated on each call to stmmac_open(), any information in there is lost, unless we specifically handle it. The STMMAC_TBS_EN bit is set when adding an etf qdisc, and the etf qdisc therefore would stop working when link was set down and then back up.
