Update to r4.3 with some USB fixes

commit 202b52b ("drm: Track drm_mm nodes with an interval tree") introduced a requirement that the special drm_mm.head_node was initialised and marked as not being allocated. It is a very special node that has no side but has a hole that represents the drm_mm address space, and holds the list of nodes. Since it is not a real node, it is not part of the node rbtree and we detect this as it being unallocated. This presumed that drm_mm_init() was initialising it to zero. It happens that i915 kzallocs its objects and so it was accidentally setting it, but for generic use we cannot make that assumption.

When do suspend/resume stress test, some log shows "rcv is not +last". The issue is that enet suspend will disable phy clock, phy link down, after resume back, enet MAC redo initial and ready to tx/rx packet, but phy still is not ready which is doing auto-negotiation. When phy link is not up, don't schdule napi soft irq. [Peter] It has fixed kernel panic after long time suspend/resume test with nfs rootfs.

…dary MGC maintain current gain in case we cross a gaintable boundary. Currently when the gain tables are changed, the device maintains the same index. Which is not necessarily equal gain, based on the table being used. This patch deterimes the current gain and sets it once the new table is loaded. This fixes issue torvalds#234.

commit d5afb6f upstream. The code where sk_clone() came from created a new socket and locked it, but then, on the error path didn't unlock it. This problem stayed there for a long while, till b0691c8 ("net: Unlock sock before calling sk_free()") fixed it, but unfortunately the callers of sk_clone() (now sk_clone_locked()) were not audited and the one in dccp_create_openreq_child() remained. Now in the age of the syskaller fuzzer, this was finally uncovered, as reported by Dmitry: ---- 8< ---- I've got the following report while running syzkaller fuzzer on 86292b3 ("Merge branch 'akpm' (patches from Andrew)") [ BUG: held lock freed! ] 4.10.0+ torvalds#234 Not tainted ------------------------- syz-executor6/6898 is freeing memory ffff88006286cac0-ffff88006286d3b7, with a lock still held there!
