* uclinux: fix gzip header parsing in binfmt_flat.cVolodymyr G. Lukiianyk2008-10-16
| | | | | | | | | | | | | | | | | | | There are off-by-one errors in decompress_exec() when calculating the length of optional "original file name" and "comment" fields: the "ret" index is not incremented when terminating '\0' character is reached. The check of the buffer overflow (after an "extra-field" length was taken into account) is also fixed. I've encountered this off-by-one error when tried to reuse gzip-header-parsing part of the decompress_exec() function. There was an "original file name" field in the payload (with miscalculated length) and zlib_inflate() returned Z_DATA_ERROR. But after the fix similar to this one all worked fine.

* hugetlb: handle updating of ACCESSED and DIRTY in hugetlb_fault()David Gibson2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | The page fault path for normal pages, if the fault is neither a no-page fault nor a write-protect fault, will update the DIRTY and ACCESSED bits in the page table appropriately. The hugepage fault path, however, does not do this, handling only no-page or write-protect type faults. It assumes that either the ACCESSED and DIRTY bits are irrelevant for hugepages (usually true, since they are never swapped) or that they are handled by the arch code. This is inconvenient for some software-loaded TLB architectures, where the _PAGE_ACCESSED (_PAGE_DIRTY) bits need to be set to enable read (write) access to the page at the TLB miss. This could be worked around in the arch TLB miss code, but the TLB miss fast path can be made simple more easily if the hugetlb_fault() path handles this, as the normal page fault path does.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

QE GPIO pin is used to poll the NAND's Ready-Not-Busy signal. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). This patch adds support for the registers held in the devices main FPGA, exposing extra information about the revision of the board through cpuinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On MPC8349E-mITX, MPC8315E-RDB and MPC837x-RDB boards there is a Freescale MC9S08QG8 (MCU) chip with the custom firmware pre-programmed. The chip is used to power-off the board by the software, and to control some GPIO pins. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| | * | powerpc: reserve two DMA channels for audio in MPC8610 HPCD device treeTimur Tabi2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale Elo DMA driver binds to all DMA channels in the device tree that are compatible with "fsl,eloplus-dma-channel". This conflicts with the sound drivers for the MPC8610 HPCD. On this board, the SSI uses two DMA channels and therefore those channels are not available for general purpose use. We change the compatible properties for these channels "fsl,ssi-dma-channel". This works because the sound drivers don't actually check the compatible property when it grabs channels.
