2009-08-21rtl8187: always set MSR_LINK_ENEDCA flag with RTL8187BHerton Ronaldo Krzesinski
RTL8187B always needs MSR_LINK_ENEDCA flag to be set even when it is in no link mode, otherwise it'll not be able to associate when this flag is not set after the change "mac80211: fix managed mode BSSID handling". By accident, setting BSSID of AP before association makes 8187B to successfuly associate even when ENEDCA flag isn't set, which was the case before the mac80211 change. But now the BSSID of AP we are trying to associate is only available after association is successful, and any attempt to associate without the needed flag doesn't work.

2009-08-21Make bitmask 'and' operators return a result codeLinus Torvalds
When 'and'ing two bitmasks (where 'andnot' is a variation on it), some cases want to know whether the result is the empty set or not. In particular, the TLB IPI sending code wants to do cpumask operations and determine if there are any CPU's left in the final set. So this just makes the bitmask (and cpumask) functions return a boolean for whether the result has any bits set.

2009-08-21x86: don't send an IPI to the empty set of CPU'sLinus Torvalds
The default_send_IPI_mask_logical() function uses the "flat" APIC mode to send an IPI to a set of CPU's at once, but if that set happens to be empty, some older local APIC's will apparently be rather unhappy. So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.

This is due to the boot trace entry variables being on the stack. Fixing this is relatively easy, initcalls are fundamentally serialized, so we can move the local variables to file scope. Note that this large stack footprint was present for a couple of months already - what pushed my system over the edge was the addition of kmemleak to the call-chain: 6) 3328 36 allocate_slab+0xb1/0x100 7) 3292 36 new_slab+0x1c/0x160 8) 3256 36 __slab_alloc+0x133/0x2b0 9) 3220 4 kmem_cache_alloc+0x1bb/0x1d0 10) 3216 108 create_object+0x28/0x250 11) 3108 40 kmemleak_alloc+0x81/0xc0 12) 3068 24 kmem_cache_alloc+0x162/0x1d0 13) 3044 52 scsi_pool_alloc_command+0x29/0x70 This pushes the total to ~3800 bytes, only a tiny bit more was needed to corrupt the on-kernel-stack thread_info. The fix reduces the stack footprint from 572 bytes to 28 bytes.

2009-08-21btrfs: fix inode rbtree corruptionFrom: Nick Piggin
Node may not be inserted over existing node. This causes inode tree corruption and I was seeing crashes in inode_tree_del which I can not reproduce after this patch. The other way to fix this would be to tie inode lifetime in the rbtree with inode while not in freeing state. I had a look at this but it is not so trivial at this point. At least this patch gets things working again.

The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves.

2009-08-19ALSA: hda - Fix probe of Toshiba laptops with ALC268 codecTakashi Iwai
There are many variants of Toshiba laptops with ALC268 codec, and it seems that a few of them don't work with model=toshiba preset since they have the secondary ALC268 codec just for HDMI output. This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device.

HP Compaq 6530s and 6531s internal speaker is silence or becomes silence within 1 minute after fresh boot. It is found that pin 0x1c must be set to PIN_OUT mode to make the speaker work. This is weird - line-in pin 0x1c and speaker pin 0x16 seem to be unrelated.

2009-08-18yellowfin: Fix buffer underrun after dev_alloc_skb() failureRoel Kluin
yellowfin_init_ring() needs to clean up if dev_alloc_skb() fails and should pass an error status up to the caller. This also prevents an buffer underrun if failure occurred in the first iteration. yellowfin_open() which calls yellowfin_init_ring() should free its requested irq upon failure.

2009-08-18mm: build_zonelists(): move clear node_load[] to __build_all_zonelists()Bo Liu
If node_load[] is cleared everytime build_zonelists() is called,node_load[] will have no help to find the next node that should appear in the given node's fallback list. Because of the bug, zonelist's node_order is not calculated as expected. This bug affects on big machine, which has asynmetric node distance. [synmetric NUMA's node distance] 0 1 2 0 10 12 12 1 12 10 12 2 12 12 10 [asynmetric NUMA's node distance] 0 1 2 0 10 12 20 1 12 10 14 2 20 14 10 This (my bug) is very old but no one has reported this for a long time. Maybe because the number of asynmetric NUMA is very small and they use cpuset for customizing node memory allocation fallback.
