* PCI MSI: shorten PCI_MSIX_ENTRY_* symbol namesHidetoshi Seto2009-06-292-15/+13

* PCI: More PATA quirks for not entering D3Alan Cox2009-06-291-0/+5
| | | | | | | | | | | | | | | | The ALi loses some state if it goes into D3. Unfortunately even with the chipset documents I can't figure out how to restore some bits of it. The VIA one saves/restores apparently fine but the ACPI _GTM methods break on some platforms if we do this and this causes cable misdetections. These are both effectively regressions as historically nothing matched the devices and then decided not to bind to them. Nowdays something is binding to all sorts of devices and a result they get dumped into D3.

* PCI: check if bus has a proper bridge device before triggering SBRYu Zhao2009-06-291-1/+1
| | | | | | | | | | For devices attached to the root bus, we can't trigger Secondary Bus Reset because there is no bridge device associated with the bus. So need to check bus->self again NULL first before using it.

* PCI: remove pci_dac_dma_... APIs on mn10300Fernando Luis Vázquez Cao2009-06-291-4/+0
| | | | | | | | | | It seems that mn10300 made it upstream after Jan Beulich's pci_dac_dma_* cleanup work and still defines pci_dac_dma_supported(). This API is not required by the PCI subsystem anymore, so remove it.

* PCI MSI: Return if alloc_msi_entry for MSI-X failedHidetoshi Seto2009-06-291-2/+8
| | | | | | | | | | | | | | | | | | | | | | In current code it continues setup even if alloc_msi_entry() for MSI-X is failed due to lack of memory. It means arch_setup_msi_irqs() might be called with msi_desc entries less than its argument nvec. At least x86's arch_setup_msi_irqs() uses list_for_each_entry() for dev->msi_list that suspected to have entries same numbers as nvec, and it doesn't check the number of allocated vectors and passed arg nvec. Therefore it will result in success of pci_enable_msix(), with less vectors allocated than requested. This patch fixes the error route to return -ENOMEM, instead of continuing the setup (proposed by Matthew Wilcox). Note that there is no iounmap in msi_free_irqs() if no msi_disc is allocated.

At this point we know the port will be recycled so we can kill the ldisc off completely rather than try and add another ldisc free up when the kref count hits zero. At this point it is safe to keep the ldisc closed as tty_ldisc waiting methods are only used from the user side, and as the final close we are the last such reference. Interrupt/driver side methods will always use the non wait version and get back a NULL. Found with kmemleak and investigated/identified by Catalin Marinas.

This is a bug as it would cause the GRO packets to linger, of course it also literally BUGs to catch error like this :) This patch changes it to napi_complete, with the obligatory IRQ reenabling. This should be safe because we've only just disabled IRQs and it does not materially affect the test conditions in between.

Have not verified that the possibility for new call_rcu() callbacks has been disabled. As a hint for checking, the functions calling call_rcu() (unx_destroy_cred and generic_destroy_cred) are registered as crdestroy function pointer in struct rpc_credops. Acked-by: Paul E.
