With the removal of msi_lookup_irq all of the functions using msi_lock operated on a single device and none of them could reasonably be called on that device at the same time. Since what little synchronization that needs to happen needs to happen outside of the msi functions, msi_lock could never be contended and as such is useless and just complicates the code.

The function msi_lookup_irq was horrible. As a side effect of running it changed dev->irq, and then the callers would need to change it back. In addition it does a global scan through all of the irqs, which seems to be the sole justification of the msi_lock. To remove the neede for msi_lookup_irq I added first_msi_irq to struct pci_dev. Then depending on the context I replaced msi_lookup_irq with dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled. msi_enabled and msix_enabled were already present in pci_dev for other reasons.

The PCI save/restore code doesn't need to care about MSI vs MSI-X, all it really wants is to say "save/restore all MSI(-X) info for this device". This is borne out in the code, we call the MSI and MSI-X save routines side by side, and similarly with the restore routines. So combine the MSI/MSI-X routines into pci_save_msi_state() and pci_restore_msi_state(). It is up to those routines to decide what state needs to be saved.

I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature.

Speed up the Intel SMBus PCI quirk by avoiding tests which can only fail.

There's an existing quirk for the kernel to use 1k IO space granularity on the Intel P64H2. It turns out however that pci_setup_bridge() in drivers/pci/setup-bus.c reads in the IO base and limit address register masks it off to the nearest 4k, and writes it back. This causes the kernel to be on 1k boundaries and the hardware to be 4k aligned. The patch below fixes the problem.

For pci mem resource that size is bigger than 4G, the sz returned by pc_size will be 0. So that resource is skipped, and register contained hi address will be treated as another 32bit resource. We need to use sz64 and pci_sz64 for 64 bit resource for clear logical. Typical usages for this: Opteron system with co-processor and the co-processor could take more than 4G RAM as pre-fetchable mem resource.

For all JMicrons except for 361 and 368, AHCI mode enable bits in the Control(1) should be set. This used to be done in both ahci and pata_jmicron but while moving programming to PCI quirk, it was removed from ahci part while still left in pata_jmicron. The implemented JMicron PCI quirk was incorrect in that it didn't program AHCI mode enable bits. If pata_jmicron is loaded first and programs those bits, the ahci ports work; otherwise, ahci device detection fails miserably. This patch makes JMicron PCI quirk clear SATA IDE mode bits and set AHCI mode bits and remove the respective part from pata_jmicron. Tested on JMB361, 363 and 368.

Fix VIA quirks that were recently broken by Alan Cox in the upstream kernel (commit 1597cacb). My understanding is that pci_find_present() doesn't work yet at the time the quirks are run. So I used a two-step quirk as is done for some other quirks already. First we detect the VIA south bridges and set the right low and high device limits, then we are ready to actually run the quirks on the affected devices.

While testing 2.6.20-rc3 on a machine with some CK804 chipsets, we noticed that quirk_nvidia_ck804_msi_ht_cap() was not detecting HT MSI capabilities anymore. It is actually caused by the MSI mapping on the root chipset being the 2nd HT capability in the chain. pci_find_ht_capability() does not seem to find anything but the first HT cap correctly, because it forgets to increment the position before looking for the next cap. The following patch seems to fix it. At least, this proves that having a ttl is good idea since the machine would have been stucked in an infinite loop if we didn't have a ttl :) We have to pass pos + PCI_CAP_LIST_NEXT to __pci_find_next_cap_ttl to get the next HT cap instead of the same one again.
