  1. Linux 2.6.22

    Linus Torvalds authored
    Woo-hoo. I'm sure somebody will report a "this doesn't compile, and
    I have a new root exploit" five minutes after release, but it still
    feels good ;)

  3. Fix permission checking for the new utimensat() system call

    Linus Torvalds authored
    Commit 1c710c8 added the utimensat()
    system call, but didn't handle the case of checking for the writability
    of the target right, when the target was a file descriptor, not a
    filename.
    
    We cannot use vfs_permission(MAY_WRITE) for that case, and need to
    simply check whether the file descriptor is writable.  The oops from
    using the wrong function was noticed and narrowed down by Markus
    Trippelsdorf.

  4. mm: double mark_page_accessed() in read_cache_page_async()

    Peter Zijlstra authored Linus Torvalds committed
    Fix a post-2.6.21 regression.
    
    read_cache_page_async() has two invocations of mark_page_accessed() which will
    launch pages right onto the active list.
    
    Remove the first one, keeping the latter one.  This avoids marking unwanted
    pages active (in the retry loop).

    qd65xx: fix PIO mode selection

    bzolnier authored
    PIO4 is a maximum PIO mode supported by a driver.  Using "255" as a max_mode
    argument to ide_get_best_pio_mode() could result in wrong timings being used
    by a driver (for "pio" equal to 5) or OOPS (for "pio" values > 5 && < 255).

    sis5513: adding PCI-ID

    Uwe Koziolek authored bzolnier committed
    The SiS966 has one additional PCI-ID 1180.
    
    If the chipset is using this PCI-ID, the primary channel is connected to the
    first PATA-port. The secondary channel is connected to SATA-ports in IDE
    emulation mode.  The legacy IO-ports are used.
    
    The including of the PCI-ID into pata_sis is not sufficient, because the legacy
    driver in drivers/ide is initialized before pata_sis.

    Fix use-after-free oops in Bluetooth HID.

    dwmw2 authored Linus Torvalds committed
    When cleaning up HIDP sessions, we currently close the ACL connection
    before deregistering the input device. Closing the ACL connection
    schedules a workqueue to remove the associated objects from sysfs, but
    the input device still refers to them -- and if the workqueue happens to
    run before the input device removal, the kernel will oops when trying to
    look up PHYSDEVPATH for the removed input device.
    
    Fix this by deregistering the input device before closing the
    connections.

  7. potential compiler error, irqfunc caller sites update

    Yoann Padioleau authored Linus Torvalds committed
    In 7d12e78 David Howells performed
    this evolution:
     "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"
    
    He correctly updated many of the function definitions that were using this
    extra regs pointer parameter but forgot to update some caller sites of
    those functions.  The reason the modifications was not properly done on all
    drivers is that some drivers were rarely compiled because they are for
    AMIGA, or that some code sites were inside #ifdefs where the option is not
    set or inside #if 0.

    and fixed the problem.

  9. PNP SMCf010 quirk: work around Toshiba Portege 4000 ACPI issues

    Bjorn Helgaas authored Linus Torvalds committed
    When we enable the SMCf010 IR device, the Toshiba Portege 4000 BIOS claims
    the device is working, but it really isn't configured correctly.  The BIOS
    *will* configure it, but only if we call _SRS after (1) reversing the order
    of the SIR and FIR I/O port regions and (2) changing the IRQ from
    active-high to active-low.
    
    This patch addresses the 2.6.22 regression:
        "no irda0 interface (2.6.21 was OK), smsc does not find chip"
    
    I tested this on a Portege 4000.  The smsc-ircc2 driver correctly detects
    the device, and "irattach irda0 -s && irdadump" shows transmitted and
    received packets.

    Processors synchronization in set_mtrr requires the .gate field to be set
    after .count field is properly initialized.  Without an explicit barrier,
    the compiler was reordering those memory stores.  That was sometimes
    causing a processor (in ipi_handler) to see the .gate change and decrement
    .count before the latter is set by set_mtrr() (which then hangs in a
    infinite loop with irqs disabled).

    i386: fix regression, endless loop in ptrace singlestep over an int80

    jwessel authored Linus Torvalds committed
    The commit 635cf99 introduced a
    regression.  Executing a ptrace single step after certain int80
    accesses will infinitely loop and never advance the PC.
    
    The TIF_SINGLESTEP check should be done on the return from the syscall
    and not before it.
    
    I loops on each single step on the pop right after the int80 which writes out
    to the console.  At that point you can issue as many single steps as you want
    and it will not advance any further.

    Fix elf_core_dump() when writing arch specific notes (spu coredumps)

    mpe authored Linus Torvalds committed
    elf_core_dump() supports dumping arch specific ELF notes, via the #define
    ELF_CORE_WRITE_EXTRA_NOTES.  Currently the only user of this is the powerpc
    spu coredump code.
    
    There is a bug in the handling of foffset WRT the arch notes, which causes
    us to erroneously increment foffset by the size of the arch notes, leaving
    a block of zeroes in the file, and causing all subsequent data in the file
    to be at <supposed position> + <arch note size>.  eg:
    
      LOAD  0x050000 0x00100000 0x00000000 0x20000 0x20000 R E 0x10000
    
    Tells us we should have a chunk of data at 0x50000.  The truth is the data
    is at 0x90dbc = 0x50000 + 0x40dbc (the size of the arch notes).
    
    This bug prevents gdb from reading the core file correctly.
    
    The simplest fix is to simply remember the size of the arch notes, and add
    it to foffset after we've written the arch notes.  The only drawback is
    that if the arch code doesn't write as many bytes as it said it would, we
    end up with a broken core dump again.  For now I think that's a reasonable
    requirement.
    
    Tested on a Cell blade, gdb no longer complains about the core file being
    bogus.
    
    While I'm here I should point out that the spu coredump code does not work
    if we're dumping to a pipe - we'll have to wait for 23 to fix that.

    [MIPS] Fix scheduling latency issue on 24K, 34K and 74K cores

    ralfbaechle authored
    The idle loop goes to sleep using the WAIT instruction if !need_resched().
    This has is suffering from from a race condition that if if just after
    need_resched has returned 0 an interrupt might set TIF_NEED_RESCHED but
    we've just completed the test so go to sleep anyway.  This would be
    trivial to fix by just disabling interrupts during that sequence as in:
    
            local_irq_disable();
            if (!need_resched())
                    __asm__("wait");
            local_irq_enable();
    
    but the processor architecture leaves it undefined if a processor calling
    WAIT with interrupts disabled will ever restart its pipeline and indeed
    some processors have made use of the freedom provided by the architecture
    definition.  This has been resolved and the Config7.WII bit indicates that
    the use of WAIT is safe on 24K, 24KE and 34K cores.  It also is safe on
    74K starting revision 2.1.0 so enable the use of WAIT with interrupts
    disabled for 74K based on a c0_prid of at least that.

    [MIPS] Add macros to encode processor revisions.

    ralfbaechle authored
    Older processors used to encode processor version and revision in two
    4-bit bitfields, the 4K seems to simply count up and even newer MTI cores
    have switched to use the 8-bits as 3:3:2 bitfield with the last field as
    the patch number.

    [MIPS] RM7000: Enable ICACHE_REFILLS_WORKAROUND_WAR.

    ralfbaechle authored
    The RM7000 processors and the E9000 cores have a bug (though PMC-Sierra
    opposes it being called that) where invalid instructions in the same
    I-cache line worth of instructions being fetched may case spurious
    exceptions.
    
    The workaround for this was only enabled for E9000 cores; enable it also
    for all RM7000-based platforms.

    If only modules were users of these functions they did not get linked into
    the kernel proper, so later module loads would fail as well.
