While doing the work for commit a6f7feae6d ("IB/mlx4: pass SMP
vendor-specific attribute MADs to firmware") we realized that the
firmware would respond on all sorts of vendor-specific MADs.
Therefore commit 97285b7817 ("mlx4_core: Add extended port
capabilities support") adds redundant code into the driver, since
there's no real reaon to maintain the extended capabilities of the
port, as they can be queried on demand (e.g the FDR10 capability).
This patch reverts commit 97285b7817 and removes the check for
extended caps from the mlx4_ib driver port query flow.

Pull CIFS fixes from Steve French
* git://git.samba.org/sfrench/cifs-2.6:
cifs: fix dentry refcount leak when opening a FIFO on lookup
CIFS: Fix mkdir/rmdir bug for the non-POSIX case
Commit 6bd4837de9 ("mm: simplify find_vma_prev()") broke memory
management on PA-RISC.
After application of the patch, programs that allocate big arrays on the
stack crash with segfault, for example, this will crash if compiled
without optimization:
int main()
{
char array[200000];
array[199999] = 0;
return 0;
}
The reason is that PA-RISC has up-growing stack and the stack is usually
the last memory area. In the above example, a page fault happens above
the stack.
Previously, if we passed too high address to find_vma_prev, it returned
NULL and stored the last VMA in *pprev. After "simplify find_vma_prev"
change, it stores NULL in *pprev. Consequently, the stack area is not
found and it is not expanded, as it used to be before the change.
This patch restores the old behavior and makes it return the last VMA in
*pprev if the requested address is higher than address of any other VMA.

Xommit ac5637611(genirq: Unmask oneshot irqs when thread was not woken)
fails to unmask when a !IRQ_ONESHOT threaded handler is handled by
handle_level_irq.
This happens because thread_mask is or'ed unconditionally in
irq_wake_thread(), but for !IRQ_ONESHOT interrupts never cleared. So
the check for !desc->thread_active fails and keeps the interrupt
disabled.
Keep the thread_mask zero for !IRQ_ONESHOT interrupts.
Document the thread_mask magic while at it.

commit 2f34ce81b8
(OMAP3: PM: Adding voltage driver support.)
introduced runtime computation of waittime to handle all potential
sys clocks available.
In the voltage processor, the SPMSUpdateWait is calculated based on
the slew rate and the voltage step (SMPSUpdateWait = slew rate *
Voltage Step). After the voltage processor receives the SMPS_Ack
signal, the Voltage Controller will wait for SMPSUpdateWait clock
cycles for the voltage to settle to the new value. For all
practical purposes, the waittime parameter is the OMAP hardware
translation of what the slew rate on the PMIC is.
As an example, with TPS62361 on OMAP4460,
step_size = 10000
slew_rate = 32000
sys_clk_rate = 38400
Our current computation results in the following:
= ((step_size / slew_rate) * sys_clk_rate) / 1000
= ((10000 / 32000) * 38400 / 1000
= 0
Fix the same using DIV_ROUND_UP as an extra wait clock cycle
is better than lesser clock cycle. For the above example, this
translates to:
= (10000 * 38400) / (1000 * 32000)
= 12

op_why_no_deleg is set to WND4_CANCELLED.

To escape having your stable storage record purged at the end of the
grace period, it's not sufficient to simply have performed a
setclientid_confirm; you also need to meet the same requirements as
someone creating a new record: either you should have done an open or
open reclaim (in the 4.0 case) or a reclaim_complete (in the 4.1 case).
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
We set cl_firststate when we first decide that a client will be
permitted to reclaim state on next boot. This happens:
- for new 4.0 clients, when they confirm their first open
- for returning 4.0 clients, when they reclaim their first open
- for 4.1+ clients, when they perform reclaim_complete
We also use cl_firststate to decide whether a reclaim_complete has
already been performed, in the 4.1+ case.
We were setting it on 4.1 open reclaims, which caused spurious
COMPLETE_ALREADY errors on RECLAIM_COMPLETE from an nfs4.1 client with
anything to reclaim.
