2009-07-04video: sm501fb: Early initialization of mm_lock mutex.Paul Mundt
Commit 537a1bf059fa312355696fa6db80726e655e7f17 (fbdev: add mutex for fb_mmap locking) introduces a ->mm_lock mutex for protecting smem assignments. Unfortunately in the case of sm501fb these happen quite early in the initialization code, well before the mutex_init() that takes place in register_framebuffer(), leading to: Badness at kernel/mutex.c:207 Pid : 1, Comm: swapper CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273) PC is at __mutex_lock_slowpath+0x72/0x1bc PR is at __mutex_lock_slowpath+0x66/0x1bc ... matroxfb appears to have the same issue and has solved it with an early mutex_init(), so we do the same for sm501fb.

2009-07-03cciss: Ignore stale commands after rebootHannes Reinecke
When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

2009-07-03MIPS: BC47xx: Fix SSB irq setupmatthieu castet
The current ssb irq setup in ssb_mipscore_init has the problem that it configures some device on some irq without checking that the irq is not taken by an other device. For example in my case PCI host is on irq 0 and IPSEC on irq 3. The current code: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This causes a problem described in [1]. This patch tries to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0. The previous example becomes: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host: - irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC I also added some code to print the irq configuration after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.

2009-07-03parisc: advertise PCI devs after "assign_resources"Grant Grundler
Alex Chiang asked me why PARISC was calling pci_bus_add_devices() and pci_bus_assign_resources() in the opposite order from everyone else. No reason and I couldn't see any data dependency. Patch below applies cleanly to 2.6.30-rc2. Later, I suspected the code worked only because no drivers would be loaded/ready until much later in the system initialization sequence. Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2. Not tested with any Dino controllers. Not tested with PCI-PCI Bridge (TBD).

Then those ranges would be handed out more than once, and things kind of go downhill from there. Introduced after 2.6.25 by ddf02886cbe665d67ca750750196ea5bf524b10b ("PCI: iova RB tree setup tweak").

2009-06-30ixgbe: fix unmap length bugJesse Brandeburg
This patch addresses three WARN_ON statements from DMA-API debug code ixgbe is mapping more than it unmaps, reduce the length of the map call and remove the "used once" local variable. found by Joerg Roedel <joerg.roedel@amd.com> in 2.6.30, so is a candidate for -stable. in addition, fix missing ->dma = 0 after unmap to prevent double free with pci_unmap_single and lastly, don't unmap (half) pages that aren't mapped.
