* spi_s3c24xx: pin configuration updatesBen Dooks2008-10-16
| | | | | | | | | | | | | | Add a pin configuration callback for the s3c24xx SPI driver, as there are several options depending on the channel and the chip in use. This is needed as the controller may not have been setup by the initial bootloader and the fact that the SPI controller gets reset over suspend/resume into slave mode but the GPIO function registers do not.

* Make the taint flags reliableAndi Kleen2008-10-16
| | | | | | | | | | | | | | | | | | | | | | It's somewhat unlikely that it happens, but right now a race window between interrupts or machine checks or oopses could corrupt the tainted bitmap because it is modified in a non atomic fashion. Convert the taint variable to an unsigned long and use only atomic bit operations on it. Unfortunately this means the intvec sysctl functions cannot be used on it anymore. It turned out the taint sysctl handler could actually be simplified a bit (since it only increases capabilities) so this patch actually removes code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, indirect_pci was changed to test if the bus number requested is the one hanging straight off the PHB, then it substitutes the bus number with another one contained in a new "self_busno" field of the pci_controller structure. However, this breaks CHRP which didn't initialize this new field, and which relies on having the right bus number passed to the hardware. This fixes it by initializing this variable properly for all CHRP bridges Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The detection of the IBM "Python" PCI host bridge on IBM CHRP machines such as old RS6000 was broken when we changed of_device_is_compatible() from strncasecmp to strcasecmp (dropped the "n" variant) due to the way IBM encodes the chip version. We fix that by instead doing a match on the model property like we do for others bridges in that file. It should be good enough for those machines. If yours is still broken, let me know.

| * | powerpc/pci: Improve detection of unassigned bridge resourcesBenjamin Herrenschmidt2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the powerpc PCI layer is not configured to re-assign everything, it currently fails to detect that a PCI to PCI bridge has been left unassigned by the firmware and tries to allocate resource for the default window values in the bridge (0...X) (with the notable exception of a hack we have in there that detects some Apple firmware unassigned bridge resources). This results in resource allocation failures, which are generally fixed up later on but it causes scary warnings in the logs and we have seen the fixup code fall over in some circumstances (a different issue to fix as well). This code improves that by providing a more complete & useful function to intuit that a bridge was left unassigned by the firmware, and thus force a full re-allocation by the PCI code without trying to allocate the existing useless resources first. The algorithm we use basically considers unassigned a window that starts at 0 (PCI address) if the corresponding address space enable bit is not set. In addition, for memory space, it considers such a resource unassigned also if the host bridge isn't configured to forward cycles to address 0 (ie, the resource basically overlaps main memory). This fixes a range of problems with things like Bare-Metal support on pSeries machines, or attempt to use partial firmware PCI setup. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
| * | powerpc: Get USE_STRICT_MM_TYPECHECKS working againDavid Gibson2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The typesafe version of the powerpc pagetable handling (with USE_STRICT_MM_TYPECHECKS defined) has bitrotted again. This patch makes a bunch of small fixes to get it back to building status. It's still not enabled by default as gcc still generates worse code with it for some reason.

| * | powerpc: Fix DMA offset for non-coherent DMABenjamin Herrenschmidt2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After Becky's work we can almost have different DMA offsets between on-chip devices and PCI. Almost because there's a problem with the non-coherent DMA code that basically ignores the programmed offset to use the global one for everything. This fixes it.
