| * PCI: Make pci_scan_slot more robustMatthew Wilcox2010-02-221-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Yinghai pointed out that the new pci_scan_slot() crashes when called on an ARI-capable slot that is empty. Fix this by exiting early from pci_scan_slot if there is no device in the slot. Also make next_ari_func() robust against devices not existing in case the ARI capability is corrupt. ARI also requires that the devices be listed in order, so if we find a function listed that is out of order, stop scanning to prevent loops.

| | | | | | | | | | | | | | | | | | | | | | | | ibmphp driver currently maps only 1KB of ebda memory area into kernel address space during driver initialization.

| * PCI: Clean up build for CONFIG_PCI_QUIRKS unsetRafael J. Wysocki2010-02-225-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, drivers/pci/quirks.c is built unconditionally, but if CONFIG_PCI_QUIRKS is unset, the only things actually built in this file are definitions of global variables and empty functions (due to the #ifdef CONFIG_PCI_QUIRKS embracing all of the code inside the file). This is not particularly nice and if someone overlooks the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced. To clean that up, move the definitions of the global variables in quirks.c that are always built to pci.c, move the definitions of the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to headers (additionally make these functions static inline) and modify drivers/pci/Makefile so that quirks.c is only built if CONFIG_PCI_QUIRKS is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Alternate Routing-ID Interpretation capability allows a single device to have up to 256 functions. They can be populated sparsely, so the current technique of scanning every eighth function is not guaranteed to find them all. By introducing a 'next_fn' function pointer, we can use the linked list of functions in the ARI capability to scan all the functions which exist. We can then speed up the pci_scan_slot by skipping the scan of subsequent devfns for PCIe devices which are the direct children of Root Ports or Downstream Ports. These devices are only permitted to implement device 0, unless they are ARI devices, in which case they'll be scanned by the ARI code above.

* | Lower USB storage settling delay to something more reasonableLinus Torvalds2010-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The five-second delay can be rather annoying, and makes the system appear much less responsive when you connect a USB drive. It's also not entirely clear that it is needed - the settling delay has at least historically been an issue on some Apple iPods, for example, and some devices have been reported to need even more than the old 5s delay. But before we penalize them all, let's see how bad it really is. Some of the reasons for long delays seem to be actual historical kernel bugs that should probably never have been papered over with a delay in the first place (there's a Ubuntu bug report for 2.6.20 about a NULL pointer dereference unless 'delay_use' is 8 or more, for example). It also looks like some distros have already shipped with delay_use=0, so the five second default may well be totally historical. In other words: "Let's see if anybody screams".

| | | | | | | | | | | | | | | | | | | | | | | | machine is compatible is an OF-specific call. It should have the of_ prefix to protect the global namespace. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Merge common function between powerpc, sparc and microblaze. Code is identical for powerpc and microblaze, but adds a lock (and release) of the devtree_lock on sparc.

| * | microblaze: remove early_init_dt_scan_cpus() and phyp_dump_*()Grant Likely2010-02-091-153/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microblaze only has one CPU, it isn't SMP at all. early_init_dt_scan_cpus() is effectively just a no-op, so remove it. Microblaze doesn't support hypervisor assisted dump either, so the phyp stuff can also go. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>
