Benjamin Herrenschmidt f3179748a1 radeonfb: Disable new color expand acceleration unless explicitely enabled
This new color expansion acceleration for radeonfb appears to trigger
problems with X on VT switch and suspend/resume on some machines. It
might be a problem in the VT layer or in X, but I haven't quite found
it yet, so in the meantime, this disables the acceleration by default,
reverting to 2.6.27 state. It can be enabled using the "accel_cexp"
module parameter or fbdev argument.

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some
point we need to find another way to detect the Targa Visionary 1000,
until then this trades a hang for some users with lower performance
for others.

ata_piix: add borked Tecra M4 to broken suspend list

we possibly dereference null.

Keith Packard b60678a75d drm/i915: Disable the GM965 MSI errata workaround.
Since applying the fix suggested by the errata (disabling MSI), we've had
issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
Most reporters of the issue have confirmed that turning MSI back on fixes
things, and given the difficulties experienced in getting reliable MSI working
on Linux, it's believable that the errata was about software issues and not
actual hardware issues.

Linus Torvalds f10a3a32ae Revert "ACPI: battery: Convert discharge energy rate to current properly"
This reverts commit 558073dd56, along with
the failed try to fix the regression it caused ("ACPI: Fix ACPI battery
regression introduced by commit 558073"), which just made things worse.

Commit aaad077638 (that failed "Fix ACPI
battery regression") got the voltage conversion confused, and fixed the
problem with Rafael's battery monitor apparently just by mistake.

So revert them both, getting us back to the 2.6.27 state in this, and
let's revisit it when people understand what's going on.

Shaddy Baddah cde6901b7b zd1211rw: use unaligned safe memcmp() in-place of compare_ether_addr()
Under my 2.6.28-rc6 sparc64, when associating to an AP through my
zd1211rw device, I was seeing kernel log messages like (not exact output):

  Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw]

For the zd1211rw module, on RX, the 80211 packet will be located after
the PLCP header in the skb data buffer. The PLCP header being 5 bytes
long, the 80211 header will start unaligned from an aligned skb
buffer.

As per Documentation/unaligned-memory-access.txt, we must replace the
not unaligned() safe compare_ether_addr() with memcmp() to protect
architectures that require alignment.

Zhu Yi b8ddafd759 ipw2200: fix netif_*_queue() removal regression
In "ipw2200: Call netif_*_queue() interfaces properly", netif_stop_queue()
and netif_wake_queue() were removed with the reason
"netif_carrier_{on,off}() handles starting and stopping packet flow into
the driver". The patch also removes a valid condition check that
ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state.
But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't
be called because linkwatch event is handled in a delayed workqueue. This
caused a kernel oops reported by Frank Seidel:
https://bugzilla.novell.com/show_bug.cgi?id=397390

This patch fixes the problem by moving the STATUS_ASSOCIATED check back
to ipw_tx_skb(). It also adds a missing netif_carrier_off() call to
ipw_disassociate().

Tomas Winkler 40a9a82991 iwlwifi: clean key table in iwl_clear_stations_table function
This patch cleans uCode key table bit map iwl_clear_stations_table
since all stations are cleared also the key table must be.

Since the keys are not removed properly on suspend by mac80211
this may result in exhausting key table on resume leading
to memory corruption during removal

This patch also fixes a memory corruption problem reported in
http://marc.info/?l=linux-wireless&m=122641417231586&w=2 and tracked in
http://bugzilla.kernel.org/show_bug.cgi?id=12040.

When the key is removed a second time the offset is set to 255 - this
index is not valid for the ucode_key_table and corrupts the eeprom pointer
(which is 255 bits from ucode_key_table).

Baruch Siach 5176da7e53 enc28j60: Fix sporadic packet loss (corrected again)
Packet data read from the RX buffer the when the RSV is at the end of the RX
buffer does not warp around. This causes packet loss, as the actual data is
never read. Fix this by calculating the right packet data location.

Thanks to Shachar Shemesh for suggesting the fix.

ifa_local is assumed to be unsigned long which lead to writing the address
at dev->dev_addr-2 instead of +2

Wilfried Klaebe 1c594c05a7 b1isa: fix b1isa_exit() to really remove registered capi controllers
On "/etc/init.d/capiutils stop", this oops happened.

The oops happens on reading /proc/capi/controllers because
capi_ctrl->procinfo is called for the wrongly not unregistered
controller, which points to b1isa_procinfo(), which was removed on
module unload.

b1isa_exit() did not call b1isa_remove() for its controllers because
io[0] == 0 on module unload despite having been 0x340 on module load.

Besides, just removing the controllers that where added on module
load time and not those that were added later via b1isa_add_card() is
wrong too - the place where all added cards are found is isa_dev[].

It's only for flushing caches appropriately for GTT access, not for actually

Keith Packard 646f0f6e43 drm/i915: Move the execbuffer domain computations together
This eliminates the dev_set_domain function and just in-lines it
where its used, with the goal of moving the manipulation and use of
invalidate_domains and flush_domains closer together. This also
avoids calling add_request unless some domain has been flushed.

Keith Packard c0d9082928 drm/i915: Rename object_set_domain to object_set_to_gpu_domain
Now that the CPU and GTT domain operations are isolated to their own
functions, the previously general-purpose set_domain function is now used
only to set GPU domains. It also has no failure cases, which is important as
this eliminates any possible interruption of the computation of new object
domains and subsequent emmission of the flushing instructions into the ring.
