2009-03-24ide: factor out processing of special commands from ide_special_rq()Bartlomiej Zolnierkiewicz
Factor out processing of special commands from ide_special_rq() to ide_do_devset() and ide_do_park_unpark(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-24ide: remove ide_do_drive_cmd()Bartlomiej Zolnierkiewicz
* Use elv_add_request() instead of __elv_add_request() in ide_do_drive_cmd(). * ide_do_drive_cmd() is used only in ide-{atapi,cd}.c so inline it there.

2009-03-22ucc_geth: Fix oops when using fixed-link supportAnton Vorontsov
commit b1c4a9dddf09fe99b8f88252718ac5b357363dc4 ("ucc_geth: Change uec phy id to the same format as gianfar's") introduced a regression in the ucc_geth driver that causes this oops when fixed-link is used: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc0151270 Oops: Kernel access of bad area, sig: 11 [#1] TMCUTU NIP: c0151270 LR: c0151270 CTR: c0017760 REGS: cf81fa60 TRAP: 0300 Not tainted (2.6.29-rc8) MSR: 00009032 <EE,ME,IR,DR> CR: 24024042 XER: 20000000 DAR: 00000000, DSISR: 20000000 TASK = cf81cba0[1] 'swapper' THREAD: cf81e000 GPR00: c0151270 cf81fb10 cf81cba0 00000000 c0272e20 c025f354 00001e80 cf86b08c GPR08: d1068200 cffffb74 06000000 d106c200 42024042 10085148 0fffd000 0ffc81a0 GPR16: 00000001 00000001 00000000 007ffeb0 00000000 0000c000 cf83f36c cf83f000 GPR24: 00000030 cf83f360 cf81fb20 00000000 d106c200 20000000 00001e80 cf83f360 NIP [c0151270] ucc_geth_open+0x330/0x1efc LR [c0151270] ucc_geth_open+0x330/0x1efc Call Trace: [cf81fb10] [c0151270] ucc_geth_open+0x330/0x1efc (unreliable) [cf81fba0] [c0187638] dev_open+0xbc/0x12c [cf81fbc0] [c0187e38] dev_change_flags+0x8c/0x1b0 This patch fixes the issue by removing offending (and somewhat duplicate) code from init_phy() routine, and changes _probe() function to use uec_mdio_bus_name(). Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

2009-03-22dm9000: locking bugfixDavid Brownell
This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

2009-03-22radeonfb: Whack the PCI PM register until it sticksBenjamin Herrenschmidt
This fixes a regression introduced when we switched to using the core pci_set_power_state(). The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.

2009-03-18smsc911x: reset last known duplex and carrier on openSteve Glendinning
smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

2009-03-18tulip: fix crash on iface up with shirq debugKyle McMartin
Tulip is currently doing request_irq before it has done its initialization. This is usually not a problem because it hasn't enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler when registering the interrupt as a sanity check. This can result in a NULL ptr dereference, so call tulip_init_ring before request_irq, and add a free_ring function to do the freeing now shared with tulip_close. Tested with a shell loop running ifup, ifdown in a loop a few hundred times with DEBUG_SHIRQ on. Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-18virtio_net: Make virtio_net support carrier detectionPantelis Koukousoulas
Impact: Make NetworkManager work with virtio_net For now the semantics are simple: There is always carrier. This allows a seamless experience with e.g., qemu/kvm where NetworkManager just configures and sets up everything automagically. If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.

2009-03-18bnx2: Fix problem of using wrong IRQ handler.Michael Chan
The MSI-X handler was chosen before the call to pci_enable_msix(). If MSI-X was not available, the wrong MSI-X handler would be used in INTA mode. This would cause a screaming interrupt problem because INTA would not be cleared by the MSI-X handler. Fixed by assigning MSI-X handler after pci_enable_msix() returns successfully.

2009-03-17USB: EHCI: expedite unlinks when the root hub is suspendedAlan Stern
This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.
