* input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playbackArjan van de Ven2008-11-301-2/+3
| | | | | | | | | | | | | | | ml_ff_playback() uses spin_(un)lock_bh. However this function is called with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196. This is not permitted, and will result in a WARN_ON in the bottom half handling code. This patch changes this function to just use spin_lock_irqsave() instead, solving the problem and simplifying the locking logic. This was reported as entry #106559 in kerneloops.org Reported-by: kerneloops.org Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* tricky one: hisax sectionsAl Viro2008-11-301-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | a) hisax_init_pcmcia() needs to be defined only if we have CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared __devinit. b) HiSax_inithardware() can go __init c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card(): checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card); The problem with it is that * hisax_cs_setup_card() is __devinit * hisax_register() is not * hisax_cs_setup_card() is a switch from hell, calling a lot of setup_some_weirdcard() depending on card->typ. _These_ are also __devinit. However, in hisax_register() we have card->typ equal to ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind all that crap, just do nothing and return 2". So we add a trimmed-down callback doing just that and passed to checkcard() by hisax_register(). _This_ is non-init (we can stand the impact on .text size).

* advansys fix on ISA-less configsAl Viro2008-11-301-0/+4
| | | | | | | | | | | | | | | | | | | The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.

| | * | | | iwlagn: fix RX skb alignmentJohannes Berg2008-11-183-13/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So I dug deeper into the DMA problems I had with iwlagn and a kind soul helped me in that he said something about pci-e alignment and mentioned the iwl_rx_allocate function to check for crossing 4KB boundaries. Since there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like something the device would fail with, but when I looked into the function for a minute anyway I stumbled over this little gem: BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff)); Clearly, that is a totally bogus check, one would hope the compiler removes it entirely. (Think about it) After fixing it, I obviously ran into it, nothing guarantees the alignment the way you want it, because of the way skbs and their headroom are allocated. I won't explain that here nor double-check that I'm right, that goes beyond what most of the CC'ed people care about. So then I came up with the patch below, and so far my system has survived minutes with 64K pages, when it would previously fail in seconds. And I haven't seen a single instance of the TX bug either. But when you see the patch it'll be pretty obvious to you why. This should fix the following reported kernel bugs: http://bugzilla.kernel.org/show_bug.cgi?id=11596 http://bugzilla.kernel.org/show_bug.cgi?id=11393 http://bugzilla.kernel.org/show_bug.cgi?id=11983 I haven't checked if there are any elsewhere, but I suppose RHBZ will have a few instances too... I'd like to ask anyone who is CC'ed (those are people I know ran into the bug) to try this patch. I am convinced that this patch is correct in spirit, but I haven't understood why, for example, there are so many unmap calls. I'm not entirely convinced that this is the only bug leading to the TX reply errors. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| | * | | | mac80211: remove ieee80211_notify_macJohannes Berg2008-11-182-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before ieee80211_notify_mac() was added, it was presented with the use case of using it to tell mac80211 that the association may have been lost because the firmware crashed/reset. Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested.

But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable* aneg or un-isolate the PHY from the MII (those functions are controlled by the same register). The code to avoid calling genphy_restart_aneg() didn't consider this. So, modify genphy_config_aneg() to also check if the PHY needs to have aneg enabled or be un-isolated before deciding not to restart aneg. This caused a problem with certain Davicom PHYs, as that driver isolates the PHY (why?) before calling genphy_config_aneg() and expects the PHY to be un-isolated by that function.
