Peek at the CQ after arming it so that we can return a hint.
This avoids missed completions due to a race between posting
CQEs and arming the CQ.
For example, CM teardown waits on MAD requests to complete with
ib_cq_poll_work(). Without this fix, the last completion might be
left on the CQ, hanging the kthread doing the teardown.
The console backtraces look like this:

The last_psn algorithm fails in the zero-byte case: it calculates
first_psn = N, last_psn = N-1. This makes the operation unretryable since
the res structure will fail the (first_psn <= psn <= last_psn) test in
find_resource().
While here, use BTH_PSN_MASK to mask the calculated last_psn.

A client might post a read followed by a send. The partner receives
and acknowledges both transactions, posting an RCQ entry for the
send, but something goes wrong with the read ACK. When the client
retries the read, the partner's responder processes the duplicate
read but incorrectly resets the PSN to the value preceding the
original send. When the duplicate send arrives, the responder cannot
tell that it is a duplicate, so the responder generates a duplicate
RCQ entry, confusing the client.

A simple userspace application might poll the CQ, find a completion,
and then attempt to post a new WQE to the SQ. A spurious error can
occur if the userspace application detects a full SQ in the instant
before the kernel is able to advance the SQ consumer pointer.
This is noticeable when using single-entry SQs with ibv_rc_pingpong
if lots of kernel and userspace library debugging is enabled.

It makes me nervous when we cast pointer parameters. I would estimate
that around 50% of the time, it indicates a bug. Here the cast is not
needed becaue u32 and and unsigned int are the same thing. Removing the
cast makes the code more robust and future proof in case any of the
types change.

A race condition fix added an rxe_qp structure to the stack in order
to be able to perform rollback in rxe_requester(), but the structure
is large enough to trigger the warning for possible stack overflow:
drivers/infiniband/sw/rxe/rxe_req.c: In function 'rxe_requester':
drivers/infiniband/sw/rxe/rxe_req.c:757:1: error: the frame size of 2064 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
This changes the rollback function to only save the psn inside
the qp, which is the only field we access in the rollback_qp
anyway.

When a computer has an IPMI system interface, the device interface
is most probably also desired. Autoloading of ipmi_devintf currently
works only if ipmi_si has allocated a platform device. That doesn't
happen if the SI interface was detected e.g. via ACPI. But ACPI
detection is preferred these days, see e.g. kernel.org bug 46741.
This patch introduces a softdep in place of the existing modalias
for ipmi_devintf.

Fix overflows seen when writing voltage and temperature limit attributes.
The value passed to DIV_ROUND_CLOSEST() needs to be clamped, and the
value parameter passed to nct7802_write_fan_min() is an unsigned long.
Also, writing values larger than 2700000 into a fan limit attribute results
in writing 0 into the chip's limit registers. The exact behavior when
writing this value is unspecified. For consistency, report a limit of
1350000 if the chip register reads 0. This may be wrong, and the chip
behavior should be verified with the actual chip, but it is better than
reporting a value of 0 (which, when written, results in writing a value
of 0x1fff into the chip register).

optimizes paravirt performance. (Pan Xinhui, Juergen Gross,

- Introduce cpu_relax_yield() and remov cpu_relax_lowlatency() to
clean up and improve the s390 lock yielding machinery and its core
kernel impact. (Christian Borntraeger)
- Micro-optimize mutexes some more. (Waiman Long)
- Reluctantly add the to-be-deprecated mutex_trylock_recursive()
interface on a temporary basis, to give the DRM code more time to
get rid of its locking hacks. Any other users will be NAK-ed on
sight. (We turned off the deprecation warning for the time being to
not pollute the build log.) (Peter Zijlstra)
