  • It didn't handle that case at all, and now dump_stack()
    can be implemented directly as show_stack(current, NULL)

  • The string setting code depends upon the original value of the
    "skip" variable, not the one that gets modified by the node
    traversal loop.

    Based upon a patch by Mark Fortescue.

  • They are handled in a ->compat_ioctl() handler, so it's just noise
    when compat_ioctl.c warns which occurs when they are used on non-SBUS
    framebuffer devices.

  • Fully unify all of the DMA ops so that subordinate bus types to
    the DMA operation providers (such as ebus, isa, of_device) can
    work transparently.

    Basically, we just make sure that for every system device we
    create, the dev->archdata 'iommu' and 'stc' fields are filled
    in.

    Then we have two platform variants of the DMA ops, one for SUN4U which
    actually programs the real hardware, and one for SUN4V which makes
    hypervisor calls.

    This also fixes the crashes in parport_pc on sparc64, reported by
    Meelis Roos.

  • All of these drivers use a silly:

    struct all_info {
    struct fb_info info;
    struct foo_par par;
    };

    struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
    all->info.par = &all->par;

    etc. etc. code sequence, basically replicating the provided
    framebuffer_alloc()/framebuffer_release(), and doing it badly.

    Not only is this massive code duplication, it also caused a
    bug in that we weren't setting the fb_info->device pointer
    which results in an OOPS when fb_is_primary_device() runs.

    Fix all of this by using framebuffer_{alloc,release}() and
    passing in "&of_device->dev" as the device pointer.

  • Start doing VTOC validation before using its contents.
    The validation is adjusted so as not to break existing setups
    that do not set the VTOC version, sanity and partition count entries.
    VTOC tables with more than 8 partitions will NOT be used.

  • Add in code to support an 82077 FDC on sun4c systems. There is a
    problem with spurious interrupts but it does apear to work.

    Testing on my SS2 (82072A FDC) shows that the floppy driver is not
    100% with sun4c any way (any spurious interrupt kills it, requiring a
    reboot to recover).

  • Don't provide fake PCI config space for sun4u.

    Also, put back the funny host controller space handling that
    at least Sabre needs. You have to read PCI host controller
    registers at their nature size otherwise you get zeros instead
    of correct values.

  • Correct the Solaris x86 number of partitions (slices) is a way that is
    backward compatible with the earlier size.

    This works without a new VTOC structure definition as the timestamp
    and v_asciilabel fields in the VTOC are not used by the kernel yet.

  • Gabriel C reports lguest doesn't compile with CONFIG_BLOCK=n. Fix this
    by introducing a config var for the block device, which depends on
    LGUEST && BLOCK. Do the same for the net driver, rather then depending
    gratuitously on CONFIG_NET.

  • Remove fs.h from mm.h. For this,
    1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
    2) Add back fs.h or less bloated headers (err.h) to files that need it.

    As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
    rebuilt down to 3444 (-12.3%).

    Cross-compile tested without regressions on my two usual configs and (sigh):

  • Introduce CONFIG_SUSPEND representing the ability to enter system sleep
    states, such as the ACPI S3 state, and allow the user to choose SUSPEND
    and HIBERNATION independently of each other.

    Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
    been chosen and the kernel is intended for SMP systems.

    Also, introduce CONFIG_PM_SLEEP which is automatically selected if
    CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
    code needed for both suspend and hibernation.

    The top-level power management headers and the ACPI code related to
    suspend and hibernation are modified to use the new definitions (the
    changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
    the number of ifdefs).

    There are many other files in which CONFIG_PM can be replaced with
    CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
    the future.

  • A non-periodic clock_event_device and the "jiffies" clock don't mix well:
    tick_handle_periodic() can go into an infinite loop.

    Currently lguest guests use the jiffies clock when the TSC is
    unusable. Instead, make the Host write the current time into the lguest
    page on every interrupt. This doesn't cost much but is more precise
    and at least as accurate as the jiffies clock. It also gets rid of
    the GET_WALLCLOCK hypercall.

    Also, delay setting sched_clock until our clock is set up, otherwise
    the early printk timestamps can go backwards (not harmful, just ugly).

  • Jason Yeh sent his crashing .config: bzImages made with
    CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we
    crash with unusual results such as:

    lguest: unhandled trap 14 at 0xc0122ae1 (0xa9)

    Relying on BSS being zero was merely laziness on my part, and
    unfortunately, lguest doesn't go through the normal startup path (which
    does this in asm).
