2007-05-22USB: remove unneeded WARN_ONAlan Stern
This patch (as883) removes an out-of-date WARN_ON from the main HCD endpoint-disable routine. The warning is triggered whenever an endpoint is disabled while the root hub is suspended. In the past that may not have been legal, but it definitely is legal now. Merely unbinding a USB driver will do it. Furthermore, I've never seen any occurrences of this warning that really did signal an actual bug or error condition. At this point it has outlived its purpose.

2007-05-22USB: more autosuspend timer stuffAlan Stern
This patch (as879) ties up some loose ends from an earlier patch. These are things I didn't think to include at the time but which clearly belonged there. If an autosuspend fails because driver activity races with the autosuspend call, restart the autosuspend timer. When a device is resumed by an external request, it counts as device activity and should update the last_busy time so that the next autoresume won't occur immediately.

2007-05-22EHCI: fix problem with BIOS handoffAlan Stern
This patch (as882) fixes a problem with the EHCI BIOS handoff. On my machine, the BIOS configures the controller and the handoff fails, leaving the controller configured. During resume-from-disk, this confuses ehci-hcd into thinking that the controller has not been tampered with. The problem is fixed by turning off the Configured Flag whenever a BIOS handoff is attempted, whether it succeeds or not.

2007-05-21IB/cm: Improve local id allocationMichael S. Tsirkin
The IB CM uses an idr for local id allocations, with a running counter as start_id. This fails to generate distinct ids if 1. An id is constantly created and destroyed 2. A chunk of ids just beyond the current next_id value is occupied This in turn leads to an increased chance of connection request being mis-detected as a duplicate, sometimes for several retries, until next_id gets past the block of allocated ids. This has been observed in practice. As a fix, remember the last id allocated and start immediately above it. This also fixes a problem with the old code, where next_id might overflow and become negative. Signed-off-by: Michael S.

2007-05-21IPoIB/cm: Fix SRQ WR leakMichael S. Tsirkin
SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on and off will, with time, leak out all WRs and then all connections will start getting RNR NAKs. Fix this in the way suggested by spec: move the QP being destroyed to the error state, wait for "Last WQE Reached" event and then post WR on a "drain QP" connected to the same CQ. Once we observe a completion on the drain QP, it's safe to call ib_destroy_qp. Signed-off-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
