* | xfs: fix remount rw with unrecognized optionsChristoph Hellwig2008-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we skip unrecognized options in xfs_fs_remount we should just break out of the switch and not return because otherwise we may skip clearing the xfs-internal read-only flag. This will only show up on some operations like touch because most read-only checks are done by the VFS which thinks this filesystem is r/w. Eventually we should replace the XFS read-only flag with a helper that always checks the VFS flag to make sure they can never get out of sync. Bug reported and fix verified by Marcel Beister on #xfs. Bug fix verified by updated xfstests/189.

| * | powerpc: Fix CHRP PCI config access for indirect_pciBenjamin Herrenschmidt2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * | powerpc/chrp: Fix detection of Python PCI host bridge on IBM CHRPsBenjamin Herrenschmidt2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | prom_init was changed to take a new argument, the address where the kernel is loaded, which is now used to copy the SMP spin loop down before use. However, only head_64.S was adapted to pass this new value, not head_32.S, thus breaking SMP boot on 32-bit SMP CHRP machines. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| * | 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/fsl: Hide MPC5121 pci bridge.John Rigby2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The class of the MPC5121 pci host bridge is PCI_CLASS_BRIDGE_OTHER while other freescale host bridges have class set to PCI_CLASS_PROCESSOR_POWERPC. This patch makes fixup_hide_host_resource_fsl match PCI_CLASS_BRIDGE_OTHER in addition to PCI_CLASS_PROCESSOR_POWERPC.

| | * | powerpc/83xx: don't probe broken PCI on mpc837x_mds boardsAnton Vorontsov2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the standalone setup the board's CPLD disables the PCI internal arbiter, thus any access to the PCI bus will hang the board. The common way to disable particular devices in the device tree is to put the "status" property with any value other than "ok" or "okay" into the device node we want to disable. So, when there is no PCI arbiter on the bus the u-boot adds status = "broken (no arbiter)" property into the PCI controller's node, and so marks the PCI controller as unavailable.

| | * | powerpc/QE: move QE_GPIO Kconfig symbol into the platforms/KconfigAnton Vorontsov2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifying user-selectable option in the qe_lib/Kconfig was a bad idea because the qe_lib/Kconfig is included into the top level Kconfig, and thus the QE_GPIO option appears at the top level menu. This patch effectively moves the QE_GPIO option under the platform menu instead. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| | * | powerpc: make Freescale QE support a selectable Kconfig optionTimur Tabi2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable option, thereby allowing users to compile kernels without any QE support. The drawback is that QE support is now disabled by default on platforms that have a QE, and so a defconfig is needed to enable QE and QE devices (like UCC GETH). Fortunately, all the current relevant defconfigs do that already. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
