0796bdb7e9 [PATCH] x86_64: stack unwinder crash fix
the new dwarf2 unwinder crashes while trying to dump the stack:

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:

        HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);

note that i386 is alot more conservative when it comes to trusting
stack pointers:

  static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
  {
         return  p > (void *)tinfo &&
                 p < (void *)tinfo + THREAD_SIZE - 3;
  }

but the x86_64 code did not take this bit of i386 code.

The fix is to align the stack pointer.

4be703906c Fix generic fb_ddc i2c edid probe msg
Benh points out that the msgs[0].flags entry never got initialized, and
since it's an automatic stack allocation, it could have any random
value, which is bad.

Rewrite the initializer to explicitly initialize all fields of the small
i2c_msg structure array we generate.  Just to keep it all obvious, let's
handle msgs[1].buf in the same initializer while we're at it, instead of
initializing that one separately later.

bb7eef6eea USB: correct keymapping on Powerbook built-in USB ISO keyboards
similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped.  Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.

It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.

This is probably 2.6.18.x material, if major distros settle on 2.6.18.

583ceada07 USB: OHCI: fix root-hub resume bug
When a suspended OHCI controller sees a port's status change, it sets
both the Root-Hub-Status-Change and the Resume-Detect bits in the
Interrupt Status register.  Processing both these bits, the driver
tries to resume the root hub twice!

This patch (as807) fixes the bug by ignoring RD if RHSC is set.  It
also prints a slightly more informative log message when a
remote-wakeup event occurs.

that the high 8 bits are ignored on receive), and will result in an
invalid QPN being used when interoperating with IPoIB connected mode.

3b46f0396c [PATCH] set default video mode on PowerBook Wallstreet
Finally add the third PowerBook Wallstreet 233MHz model to the list of
known display resolutions.

Without this change, a 640x480 video mode is used.  A workaround so far was
to boot with 'video=atyfb:vmode:14'

a9083081b5 [PATCH] eCryptfs: dput() lower d_parent on rename
On rename, for both the old and new lower dentry objects, eCryptfs is
missing a dput on the lower parent directory dentry.  This patch will
prevent the BUG() at fs/dcache.c:613 from being hit after renaming a file
inside eCryptfs and then doing a umount on the lower filesystem.

 <0>Kernel panic - not syncing: Aiee, killing interrupt handler!

The root cause is that some irq_chip variables, especially ia64_msi_chip,
initiate their memeber end to point to NULL. __do_IRQ doesn't check
if irq_chip->end is null and just calls it after processing the interrupt.

As irq_chip->end is called at many places, so I fix it by reinitiating
irq_chip->end to dummy_irq_chip.end, e.g., a noop function.

The root cause is the device struct is initialized twice.

If the device is allocated dynamically by platform_device_alloc,
platform_device_alloc will initialize struct device, then,
platform_device_add should be used to register the device.

The difference between platform_device_register and platform_device_add is
platform_device_register will initiate the device while platform_device_add
won't.
