commit 68f194e027ecfbbc8d5515bc40787e542eed59e9 upstream.

For some unknown reason, on a MacBookPro5,3 the iSight sometimes report
a different video format GUID. This patch add the other (wrong) GUID to
the format table, making the iSight work always w/o other problems.

What it should report: 32595559-0000-0010-8000-00aa00389b71
What it often reports: 32595559-0000-0010-8000-000000389b71

ath5k: initialize ah->ah_current_channel

commit b6855772f4a22c4fbdd4fcaceff5c8a527035123 upstream.

ath5k assumes ah_current_channel is always a valid pointer in
several places, but a newly created interface may not have a
channel.  To avoid null pointer dereferences, set it up to point
to the first available channel until later reconfigured.

This fixes the following oops:

ecryptfs: Bugfix for error related to ecryptfs_hash_buckets

commit a6f80fb7b5986fda663d94079d3bba0937a6b6ff upstream.

The function ecryptfs_uid_hash wrongly assumes that the
second parameter to hash_long() is the number of hash
buckets instead of the number of hash bits.
This patch fixes that and renames the variable
ecryptfs_hash_buckets to ecryptfs_hash_bits to make it
clearer.

commit b70f4e85bfc4d7000036355b714a92d5c574f1be upstream.

Typo in down_spin() meant it only read the low 32 bits of the
"serve" value, instead of the full 64 bits. This results in the
system hanging when the values in ticket/serve get larger than
32-bits. A big enough system running the right test can hit this
in a just a few hours.

eeepc-laptop: check wireless hotplug events

commit bc9d24a3aeb1532fc3e234907a8b6d671f7ed68f upstream.

Before we mark the wireless device as unplugged, check PCI config space
to see whether the wireless device is really disabled (and vice versa).
This works around newer models which don't want the hotplug code, where
we end up disabling the wired network device.

My old 701 still works correctly with this.  I can also simulate an
afflicted model by changing the hardcoded PCI bus/slot number in the
driver, and it seems to work nicely (although it is a bit noisy).

In future this type of hotplug support will be implemented by the PCI
core.  The existing blacklist and the new warning message will be
removed at that point.

It just hit me.
It's the offset calculation in reloc_location() which overflows:
        return (void *)elf->hdr + sechdrs[section].sh_offset +
               (r->r_offset - sechdrs[section].sh_addr);

E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

commit b561e8274f75831ee87e4ea378cbb1f9f050a51a upstream.

The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.

And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!
