2008-10-16uclinux: fix gzip header parsing in binfmt_flat.cVolodymyr G. Lukiianyk1-3/+3
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.

2008-10-16hugetlb: handle updating of ACCESSED and DIRTY in hugetlb_fault()David Gibson1-5/+18
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.

A series of patches introduce a generic header file for the software IO/TLB implementation in lib/swiotlb.c. Currently each architecture using this code defines the prototypes itself. The prototypes are moved to include/linux/swiotlb.h and this file is included in architecture specific code for X86 and IA64.

2008-10-15xfs: fix remount rw with unrecognized optionsChristoph Hellwig1-1/+1
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.

2008-10-14rtc-cmos: look for PNP RTC first, then for platform RTCBjorn Helgaas1-15/+18
We shouldn't rely on "pnp_platform_devices" to tell us whether there is a PNP RTC device. I introduced "pnp_platform_devices", but I think it was a mistake. All it tells us is whether we found any PNPBIOS or PNPACPI devices. Many machines have some PNP devices, but do not describe the RTC via PNP. On those machines, we need to do the platform driver probe to find the RTC. We should just register the PNP driver and see whether it claims anything. If we don't find a PNP RTC, fall back to the platform driver probe. This (in conjunction with the arch/x86/kernel/rtc.c patch to add a platform RTC device when PNP doesn't have one) should resolve these issues: http://bugzilla.kernel.org/show_bug.cgi?id=11580 https://bugzilla.redhat.com/show_bug.cgi?id=451188 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: Rafael J.

2008-10-14x86: register a platform RTC device if PNP doesn't describe itBjorn Helgaas1-4/+18

2008-10-15powerpc: Fix CHRP PCI config access for indirect_pciBenjamin Herrenschmidt1-1/+1
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>
2008-10-15powerpc/chrp: Fix detection of Python PCI host bridge on IBM CHRPsBenjamin Herrenschmidt1-1/+1
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.

2008-10-15powerpc/pci: Improve detection of unassigned bridge resourcesBenjamin Herrenschmidt1-47/+116
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>

Move rtc_wake_setup() from drivers/acpi/glue.c into the RTC driver in drivers/rtc/rtc-cmos.c. This removes the ordering constraint between the module_init(acpi_rtc_init) and the cmos_do_probe() code that depends on it. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: Rafael J.
