2013-02-18mac80211: stringify mesh peering eventsThomas Pedersen
Convert mesh peering events into strings and make the debug output a little easier to read. Also stop printing the llid and plid since these don't change across peering states and are random numbers anyway so they just amount to noise.

2013-02-18mac80211: clean up mesh HT operationThomas Pedersen
ieee80211_ht_cap_ie_to_sta_ht_cap() will clean up the ht_supported flag and station bandwidth field for us if the peer beacon doesn't have an HT capability element (is operating as non-HT). Also, we don't really need a special station ch_width member to track the station operating mode any more so use sta.bandwidth instead.

2013-02-18mac80211: fix harmless station flush warningJohannes Berg
If an interface is set down while authenticating or associating, there's a station entry that will be removed by the flushing in do_stop() and that will cause a warning.

This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2013-02-16generic-adc-battery: Fix forever loop in gab_remove()Dan Carpenter
There is a forever loop calling iio_channel_release() because the "chan < " part of the "chan < ARRAY_SIZE()" is missing. This is in both the error handling on probe and also in the remove function. The other thing is that it's possible for some of the elements of the adc_bat->channel[chan] array to be an ERR_PTR(). I've changed them to be NULL instead. We're still not allowed to pass NULLs to iio_channel_release() so I've added a check. Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement as a small cleanup.

When running in BE mode we see the values in mm->context.id are stored with the highest value first, so the LDR in the arch/arm/mm/proc-macros.S reads the wrong part of this field.

2013-02-16ARM: 7646/1: mm: use static_vm for managing static mapped areasJoonsoo Kim
A static mapped area is ARM-specific, so it is better not to use generic vmalloc data structure, that is, vmlist and vmlist_lock for managing static mapped area. And it causes some needless overhead and reducing this overhead is better idea. Now, we have newly introduced static_vm infrastructure. With it, we don't need to iterate all mapped areas. Instead, we just iterate static mapped areas. It helps to reduce an overhead of finding matched area. And architecture dependency on vmalloc layer is removed, so it will help to maintainability for vmalloc layer.

2013-02-16ARM: 7645/1: ioremap: introduce an infrastructure for static mapped areaJoonsoo Kim
In current implementation, we used ARM-specific flag, that is, VM_ARM_STATIC_MAPPING, for distinguishing ARM specific static mapped area. The purpose of static mapped area is to re-use static mapped area when entire physical address range of the ioremap request can be covered by this area. This implementation causes needless overhead for some cases. For example, assume that there is only one static mapped area and vmlist has 300 areas. Every time we call ioremap, we check 300 areas for deciding whether it is matched or not. Moreover, even if there is no static mapped area and vmlist has 300 areas, every time we call ioremap, we check 300 areas in now. If we construct a extra list for static mapped area, we can eliminate above mentioned overhead. With a extra list, if there is one static mapped area, we just check only one area and proceed next operation quickly. In fact, it is not a critical problem, because ioremap is not frequently used. But reducing overhead is better idea. Another reason for doing this work is for removing architecture dependency on vmalloc layer. I think that vmlist and vmlist_lock is internal data structure for vmalloc layer. Some codes for debugging and stat inevitably use vmlist and vmlist_lock. But it is preferable that they are used as least as possible in outside of vmalloc.c Now, I introduce an ARM-specific infrastructure for static mapped area. In the following patch, we will use this and resolve above mentioned problem.

2013-02-16perf/x86/amd: Enable northbridge performance counters on AMD family 15hJacob Shin
On AMD family 15h processors, there are 4 new performance counters (in addition to 6 core performance counters) that can be used for counting northbridge events (i.e. DRAM accesses). Their bit fields are almost identical to the core performance counters. However, unlike the core performance counters, these MSRs are shared between multiple cores (that share the same northbridge). We will reuse the same code path as existing family 10h northbridge event constraints handler logic to enforce this sharing.

2013-02-15ixgbe: Update DESC_NEEDED define to adjust for changes to MAX_SKB_FRAGSAlexander Duyck
Recent changes have made it so that MAX_SKB_FRAGS is now never less than 16. As a result we were seeing issues on systems with 64K pages as it would cause DESC_NEEDED to increase to 68, and we would need over 136 descriptors free before clean_tx_irq would wake the queue. This patch makes it so that DESC_NEEDED is always MAX_SKB_FRAGS + 4. This should prevent any possible deadlocks on the systems with 64K pages as we will now only require 42 descriptors to wake.
