net: phy: fix auto-negotiation stall due to unavailable interrupt

2017-04-26T18:32:00Z

The Ethernet link on an interrupt driven PHY was not coming up if the Ethernet cable was plugged before the Ethernet interface was brought up. The patch trigger PHY state machine to update link state if PHY was requested to do auto-negotiation and auto-negotiation complete flag already set. During power-up cycle the PHY do auto-negotiation, generate interrupt and set auto-negotiation complete flag. Interrupt is handled by PHY state machine but doesn't update link state because PHY is in PHY_READY state. After some time MAC bring up, start and request PHY to do auto-negotiation. If there are no new settings to advertise genphy_config_aneg() doesn't start PHY auto-negotiation. PHY continue to stay in auto-negotiation complete state and doesn't fire interrupt. At the same time PHY state machine expect that PHY started auto-negotiation and is waiting for interrupt from PHY and it won't get it.

mmc: sdio: fix alignment issue in struct sdio_func

2017-04-18T17:18:07Z

Certain 64-bit systems (e.g. Amlogic Meson GX) require buffers to be used for DMA to be 8-byte-aligned. struct sdio_func has an embedded small DMA buffer not meeting this requirement. When testing switching to descriptor chain mode in meson-gx driver SDIO is broken therefore. Fix this by allocating the small DMA buffer separately as kmalloc ensures that the returned memory area is properly aligned for every basic data type.

block: fix bio_will_gap() for first bvec with offset

2017-04-14T19:58:29Z

Commit 729204ef49ec("block: relax check on sg gap") allows us to merge bios, if both are physically contiguous. This change can merge a huge number of small bios, through mkfs for example, mkfs.ntfs running time can be decreased to ~1/10. But if one rq starts with a non-aligned buffer (the 1st bvec's bv_offset is non-zero) and if we allow the merge, it is quite difficult to respect sg gap limit, especially the max segment size, or we risk having an unaligned virtual boundary. This patch tries to avoid the issue by disallowing a merge, if the req starts with an unaligned buffer. Also add comments to explain why the merged segment can't end in unaligned virt boundary.

Pull cgroup fixes from Tejun Heo: "This contains fixes for two long standing subtle bugs: - kthread_bind() on a new kthread binds it to specific CPUs and prevents userland from messing with the affinity or cgroup membership. Unfortunately, for cgroup membership, there's a window between kthread creation and kthread_bind*() invocation where the kthread can be moved into a non-root cgroup by userland. Depending on what controllers are in effect, this can assign the kthread unexpected attributes. For example, in the reported case, workqueue workers ended up in a non-root cpuset cgroups and had their CPU affinities overridden. This broke workqueue invariants and led to workqueue stalls. Fixed by closing the window between kthread creation and kthread_bind() as suggested by Oleg. - There was a bug in cgroup mount path which could allow two competing mount attempts to attach the same cgroup_root to two different superblocks. This was caused by mishandling return value from kernfs_pin_sb().
