2010-10-11Revert "wireless: Use first phyX name available when registering phy devices."Johannes Berg
This reverts commit 5a254ffe3ffdfa84fe076009bd8e88da412180d2. The commit failed to take into account that allocated wireless devices (wiphys) are not added into the device list upon allocation, but only when they are registered. Therefore, it opened up a race between allocating and registering a name, so that if two processes allocate and register concurrently ("alloc, alloc, register, register" rather than "alloc, register, alloc, register") the code will attempt to use the same name twice.

Stanse found that i2400m_rx frees skb, but still uses skb->len even though it has skb_len defined. So use skb_len properly in the code. And also define it unsinged int rather than size_t to solve compilation warnings.

2010-10-11ATM: iphase, remove sleep-inside-atomicJiri Slaby
Stanse found that ia_init_one locks a spinlock and inside of that it calls ia_start which calls: * request_irq * tx_init which does kmalloc(GFP_KERNEL) Both of them can thus sleep and result in a deadlock. I don't see a reason to have a per-device spinlock there which is used only there and inited right before the lock location. So remove it completely.

2010-10-11neigh: speedup neigh_hh_init()Eric Dumazet
When a new dst is used to send a frame, neigh_resolve_output() tries to associate an struct hh_cache to this dst, calling neigh_hh_init() with the neigh rwlock write locked. Most of the time, hh_cache is already known and linked into neighbour, so we find it and increment its refcount. This patch changes the logic so that we call neigh_hh_init() with neighbour lock read locked only, so that fast path can be run in parallel by concurrent cpus. This brings part of the speedup we got with commit c7d4426a98a5f (introduce DST_NOCACHE flag) for non cached dsts, even for cached ones, removing one of the contention point that routers hit on multiqueue enabled machines. Further improvements would need to use a seqlock instead of an rwlock to protect neigh->ha[], to not dirty neigh too often and remove two atomic ops.

2010-10-11sh: oprofile: Use perf-events oprofile backendMatt Fleming
Now that we've got a generic perf-events based oprofile backend we might as well make use of it seeing as SH doesn't do anything special with its oprofile backend. Also introduce a new CONFIG_HW_PERF_EVENTS symbol so that we can fallback to using the timer interrupt for oprofile if the CPU doesn't support perf events. Also, to avoid a section mismatch warning we need to annotate oprofile_arch_exit() with an __exit marker.

2010-10-11oprofile: Abstract the perf-events backendMatt Fleming
Move the perf-events backend from arch/arm/oprofile into drivers/oprofile so that the code can be shared between architectures. This allows each architecture to maintain only a single copy of the PMU accessor functions instead of one for both perf and OProfile. It also becomes possible for other architectures to delete much of their OProfile code in favour of the common code now available in drivers/oprofile/oprofile_perf.c.

i.MX35 CPUs marked with "MCIMX357CJQ5C M99V CTHA0943B" are coming with bogus L2 cache settings. If these settings are kept unmodified prior enabling the L2 cache the CPU runs amok immediately when its enabled. This fix should not hurt already working CPUs, as they are using the written register value already.

2010-10-11workqueue: add and use WQ_MEM_RECLAIM flagTejun Heo
Add WQ_MEM_RECLAIM flag which currently maps to WQ_RESCUER, mark WQ_RESCUER as internal and replace all external WQ_RESCUER usages to WQ_MEM_RECLAIM. This makes the API users express the intent of the workqueue instead of indicating the internal mechanism used to guarantee forward progress. This is also to make it cleaner to add more semantics to WQ_MEM_RECLAIM. For example, if deemed necessary, memory reclaim workqueues can be made highpri. This patch doesn't introduce any functional change.
