2013-07-30RDMA/cma: Fix gcc warningPaul Bolle1-4/+3
Building cma.o triggers this gcc warning: drivers/infiniband/core/cma.c: In function ‘rdma_resolve_addr’: drivers/infiniband/core/cma.c:465:23: warning: ‘port’ may be used uninitialized in this function [-Wmaybe-uninitialized] drivers/infiniband/core/cma.c:426:5: note: ‘port’ was declared here This is a false positive, as "port" will always be initialized if we're at "found". But if we assign to "id_priv->id.port_num" directly, we can drop "port". That will, obviously, silence gcc.

2013-07-30net/fec: Don't let ndo_start_xmit return NETDEV_TX_BUSY without linkUwe Kleine-König1-5/+0
Don't test for having link and let hardware deal with this situation. Without this patch I see a machine running an -rt patched Linux being stuck in sch_direct_xmit when it looses link while there is still a packet to be sent. In this case the fec_enet_start_xmit routine returned NETDEV_TX_BUSY which makes the network stack reschedule the packet and so sch_direct_xmit calls fec_enet_start_xmit again. I failed to reproduce a complete hang without -rt, but I think the problem exists there, too. Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-07-309p: client: remove unused code and any reference to "cancelled" functionAndi Shyti2-10/+2
This patch reverts commit 80b45261a0b263536b043c5ccfc4ba4fc27c2acc which was implementing a 'cancelled' functionality to notify that a cancelled request will not be replied. This implementation was not used anywhere and therefore removed. Signed-off-by: Andi Shyti <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-07-30Revert "RDMA/nes: Fix compilation error when nes_debug is enabled"Roland Dreier1-2/+2
This reverts commit bca1935ccdec, which removes variables nes_tcp_state_str and nes_iwarp_state_str, assuming that they aren't defined. However, they are defined within a #ifdef NES_DEBUG statement, which if enabled causes "defined but not used" compiler warning, when the variables are removed.

2013-07-30drm/radeon/atom: initialize more atom interpretor elements to 0Alex Deucher1-0/+5
The ProcessAuxChannel table on some rv635 boards assumes the divmul members are initialized to 0 otherwise we get an invalid fb offset since it has a bad mask set when setting the fb base.

2013-07-30nl80211: fix another nl80211_fam.attrbuf raceJohannes Berg1-2/+4
This is similar to the race Linus had reported, but in this case it's an older bug: nl80211_prepare_wdev_dump() uses the wiphy index in cb->args[0] as it is and thus parses the message over and over again instead of just once because 0 is the first valid wiphy index. Similar code in nl80211_testmode_dump() correctly offsets the wiphy_index by 1, do that here as well.

2013-07-30mutex: Fix w/w mutex deadlock injectionMaarten Lankhorst1-2/+2
The check needs to be for > 1, because ctx->acquired is already incremented. This will prevent ww_mutex_lock_slow from returning -EDEADLK and not locking the mutex. It caused a lot of false gpu lockups on radeon with CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y because a function that shouldn't be able to return -EDEADLK did.

2013-07-30sched: Ensure update_cfs_shares() is called for parents of ↵Peter Zijlstra1-0/+1
continuously-running tasks We typically update a task_group's shares within the dequeue/enqueue path. However, continuously running tasks sharing a CPU are not subject to these updates as they are only put/picked. Unfortunately, when we reverted f269ae046 (in 17bc14b7), we lost the augmenting periodic update that was supposed to account for this; resulting in a potential loss of fairness. To fix this, re-introduce the explicit update in update_cfs_rq_blocked_load() [called via entity_tick()].

2013-07-30MIPS: BMIPS: fix slave CPU booting when physical CPU is not 0Florian Fainelli2-3/+13
The current BMIPS SMP code assumes that the slave CPU is physical and logical CPU 1, but on some systems such as BCM3368, the slave CPU is physical CPU0. Fix the code to read the physical CPU (thread ID) we are running this code on, and adjust the relocation vector address based on it. This allows bringing up the second CPU on BCM3368 for instance.

2013-07-30MIPS: uapi/asm/siginfo.h: Fix GCC 4.1.2 compilationMaciej W. Rozycki1-3/+4
It wasn't until GCC 4.3 I believe that the __SIZEOF_*__ predefined macros were added. The change below switches <uapi/asm/siginfo.h> to the _MIPS_SZLONG macro so that compilation with e.g. GCC 4.1.2 succeeds. This is a user API header so I think this is even more important, for older userland support. The change adds an unsuccessful default too, to catch any compiler configuration oddities.

2013-07-30ath10k: defer hw setup to start/stop mac80211 hooksMichal Kazior3-32/+81
This fixes suspend-to-disk. The hardware is now re-initialized upon freeze/thaw properly. This also makes suspend/resume re-initialize the hardware as WoWLAN support is not done yet.

Split up fw-related and hw-related suspension code. Although we don't advertise WoW support to mac80211 yet it's useful to keep the code in suspend/resume hooks. At this point there's no need to keep pci pm ops. In case of WoW mac80211 calls ath10k_suspend() which should take care of entering low-power mode.
