Pull one more infiniband revert from Roland Dreier:
"One more last-second RDMA change for 3.19: Yann realized that the
previous revert of new userspace ABI did not go far enough, and we're
still exposing a change that we don't want. Revert even closer to
3.18 interface to make sure we get things right in the long run"
Yann Droneaud pipes up:
"I hope this could go in v3.19 as, at this stage, we don't want to
expose any bits of this ABI in a released kernel"
* tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband:
Revert "IB/core: Add support for extended query device caps"

UARTs which do not trigger THRE interrupt if the fifo is already
empty when the interrupt is enabled need tx primed manually. These
UARTs are identified by the UART_BUG_TXEN flag to enable the
required workaround.
However, the current workaround is broken; if the fifo is already
empty but the shifter is still transmitting, then serial8250_tx_chars()
will not be called but no further THRE interrupt will occur, and
tx will stall. The appropriate check is for fifo empty (THRE), not
transmitter empty (TEMT).

A few redundant switch cases as well as a redundant if/else
within one of the cases was consolidated to a single call.
The cases are intentionally retained for documentation purposes.
case WIFI_REASSOCREQ,WIFI_PROBEREQ,WIFI_BEACON,WIFI_ACTION all
have the same effect - notably the also for WIFI_PROBEREQ where
the if/else is executing the same function.
These redundant cases could all be dropped and consolidated into
the default but probably it is better for documentation/readability
to leave them in the switch/case explicitly.

The if and the else branch code are identical - so the condition has no
effect on the effective code - this patch removes the condition and the
duplicated code. Due to this being a fall-through-if here - the first
if condition has no effect either - so it also can be removed.
struct mlme_priv is thus also no longer needed here.

Commit ab909585b813 ("staging: lustre: Cleanup variable declarations
in mdc_enqueue()") broke Lustre flock handling introducing access
to uninitialized req variable, leading to bizzare crash in a later
call to __req_capsule_offset with invalid pill value.
Set req to NULL just for this case as in all other cases req is
explicitly initialized with request packing call.

It is possible that when fld client is trying to lookup seq
on one of MDT, but the connection between the client and the MDT
is not being initialized yet, especially during striped dir creation,
because client will only send create req to the master MDT, then
master MDT will distribute the operation to all of other MDT, instead
of client distributing these requests, which will usually trigger
the connection.
In this case, we will send the fld request to MDT0, since it has
all of location information.

When the time of LRU resizing exceeds waiting period of
recalculation, the ldlm daemon will keep on resizing without any
interval of rest. That will cause high CPU load.
This patch fixes the problem by setting the recalculation timestamp
after LRU resizing finishes rather than before it. What is more, an
interval of one second is enforced between each recalculation.
