8a32352661 defxx: Fix the handling of ioremap() failures
If ioremap_nocache() is unfortunate enough to fail, the error code is not
set correctly leading to a false success from dfx_register().  This change
fixes the problem.

b4ed372b29 sky2: dont set bogus bit in PHY register
This code inherited from the sk98lin driver is incorrect on the Yukon2.
The GPHY_CTRL register values are specific to the internal PHY of the chip
and the values used were leftovers.
Driver was setting bit 13 which is now the INT polarity for the PHY!

Labeling a variable as __attribute_used__ is ambiguous: it means

There is no such thing as labeling a variable as __attribute__((used)).  We

eaad084bb0 NOHZ: prevent multiplication overflow - stop timer for huge timeouts
get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case
there is no timer pending. On 64 bit machines this results in a
multiplication overflow in tick_nohz_stop_sched_tick().

Reported by: Dave Miller <davem@davemloft.net>

Make the return value a constant and limit the return value to a 32 bit
value.

When the max timeout value is returned, we can safely stop the tick
timer device. The max jiffies delta results in a 12 days timeout for
HZ=1000.

In the long term the get_next_timer_interrupt() code needs to be
reworked to return ktime instead of jiffies, but we have to wait until
the last users of the original NO_IDLE_HZ code are converted.

ec56dc0b7f IPoIB/cm: Fix performance regression on Mellanox
commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe
performance regression on Mellanox cards, because keeping a QP in the
error state for extended periods of time moves hardware to the slow
path (until the QP is destroyed).  For example, MPI latency goes from
~3 usecs to ~7 usecs.

Fix this by posting a send WR on one of the QPs that are being
flushed, instead of using a separate drain QP that is kept in the
error state.

This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>,
reported and bisected by Scott Weitzenkamp at Cisco and debugged by
Sasha Mikheev at Voltaire.

8b7e15772a IB/mthca: Fix handling of send CQE with error for QPs connected to SRQ
mthca_free_err_wqe() currently treats both send and receive CQEs
identically if a QP is using an SRQ.  But for Tavor hardware, send
CQEs with error can be chained together even if the RQ is part of SRQ,
so we may miss some CQEs.

Fix by following the WQE chain for all send CQEs even for non-SRQ QPs.

This fixes crashes in IPoIB CM:

d5d4db704b USB: replace flush_workqueue with cancel_sync_work
This patch (as912) replaces a couple of calls to flush_workqueue()
with cancel_sync_work() and cancel_rearming_delayed_work().  Using a
more directed approach allows us to avoid some nasty deadlocks.  The
prime example occurs when a first-level device (the parent is a root
hub) is removed while at the same time the root hub gets a remote
wakeup request.  khubd would try to flush the autosuspend workqueue
while holding the root-hub's lock, and the remote-wakeup workqueue
routine would be waiting to lock the root hub.

The patch also reorganizes the power management portion of
usb_disconnect(), separating it out into its own routine.  The
autosuspend workqueue entry is cancelled immediately instead of
waiting for the device's release routine.  In addition,
synchronization with the autosuspend thread is carried out even for
root hubs (an oversight in the original code).

d7ea3be56a [PATCH] hostap: Allocate enough tailroom for TKIP
When hostap_tx_encrypt() tries to allocate enough headroom and
tailroom for ieee80211 encryption, it only makes enough room for the
"mpdu" phase of the operation, but forgets about the "msdu" phase.
(For TKIP, these two phases require, respectively, 4 and 8 bytes of
tailroom, per the "ieee80211_crypt_tkip" structure at the bottom of
net/ieee80211/ieee80211_crypt_tkip.c.)

7db35f31cb [SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.
Several interfaces were missing and others misnumbered or
improperly documented.

Also, make sure to check the return value when registering
the kernel TSBs with the hypervisor.  This helped to find
the 4MB kernel TSB alignment bug fixed in a previous changeset.

1) The TSB lookup was not using the correct hash mask.

2) It was not aligned on a boundary equal to it's size,
   which is required by the sun4v Hypervisor.

wasn't having it's return value checked, and that bug will be fixed up
as well in a subsequent changeset.

It was using an immediate _PAGE_EXEC_4U value in an 'and'
instruction to perform the test.  This doesn't work because
the immediate field is signed 13-bit, this the mask being
tested against the PTE was 0x1000 sign-extended to 32-bits
instead of just plain 0x1000.

b00ccd0f0b [SPARC]: Linux always started with 9600 8N1
The Linux kernel ignored the PROM's serial settings (115200,n,8,1 in
my case). This was because mode_prop remained "ttyX-mode" (expected:
"ttya-mode") due to the constness of string literals when used with
"char *". Since there is no "ttyX-mode" property in the PROM, Linux
always used the default 9600.

[ Investigation of the suncore.s assembler reveals that gcc optimizied
  away the stores, yet did not emit a warning, which is a pretty
  anti-social thing to do and is the only reason this bug lived for
  so long -DaveM ]
