The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from txdone routine. So Unconditional call to the
netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.In this driver NAPI was enabled on 2.6.33-rc1 so this is
regression from 2.6.32 kernel.Reported-by: Ralf Roesch

Check for error return from pci_map_single/pci_map_page and clean up.
With this and the previous patch the driver was able to handle a significant

geode-mfgpt: restore previous behavior for selecting IRQ
The MFGPT IRQ used to be, in order of decreasing priority,
* IRQ supplied by the user as a boot-time parameter,
* IRQ previously set by the BIOS or another driver,
* default IRQ given at compile time.Return to this behavior, which got broken when splitting the
MFGPT/clocksource driver for 2.6.33-rc1.Signed-off-by: Jens Rottmann

This also modifies the unused PRAMIN PT entries to be all zeroes, can't
really recall why I used 9/0 initially, just that it didn't work for
some reason. It was likely masking a bug elsewhere that's since been
fixed.Signed-off-by: Ben Skeggs

This commit changes nouveau to construct PTEs which look very much like
the ones the binary driver creates.I presume that filling multiple PTEs identically with length flags and
the physical address of the start of a block of VRAM is a hint to the
memory controller that it need not perform additional page table lookups
for that range of addresses.Signed-off-by: Ben Skeggs

ACPI deep C-state entry had a long standing bug/missing feature, wherein we were sending
resched IPIs when an idle CPU is in mwait based deep C-state. Only mwait based C1 was using
the write to the monitored address to wake up mwait'ing CPU.This patch changes the code to retain TS_POLLING bit if we are entering an mwait based
deep C-state.The patch has been verified to reduce the number of resched IPIs in general and also
improves the performance/power on workloads with low system utilization (i.e., when mwait based
deep C-states are being used).Fixes "netperf ~50% regression with 2.6.33-rc1, bisect to 1b9508f"

Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash
while aborting hibernation) attempted to fix a regression introduced
by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915:
implement new pm ops for i915), but it went too far trying to split
the freeze/suspend and resume/thaw parts of the code. As a result,
it introduced another regression, which only is visible on some systems.Fix the problem by merging i915_drm_suspend() with
i915_drm_freeze() and moving some code from i915_resume()
into i915_drm_thaw(), so that intel_opregion_free() and
intel_opregion_init() are also executed in the freeze and thaw code
paths, respectively.Signed-off-by: Rafael J. Wysocki

Check the frame control for ieee80211_is_data_qos() is true before
counting the number of tfds can be free, the tfds_in_queue only
increment when ieee80211_is_data_qos() is true before transmit; so it
should only decrement if the type match.Remove ieee80211_is_data_qos check for frame_ctrl in tx_resp to avoid
invalid information pass from uCode.Signed-off-by: Stanislaw Gruszka

When polled input device is opened and closed and there are no other
users of polled device, the workqueue is created and destroyed in
every open / close operation. It is probable that at some point
dynamic allocation of internal parts of the workqueue cause changes to the
workqueue.When a work is queued to the workqueue the work struct contains pointers
to the workqueue data. If the workqueue has been changed and the work
has never been queued to the new workqueue, work-struct contains pointers
to the non-existing workqueue. This will cause crash at the work
cancellation during device close since cancellation of a work assumes
that the workqueue exists.To prevent that, work struct is cleaned up at device close. This keeps
work struct clean for the next use.Signed-off-by: Samu Onkalo

The temperature and voltage limits currently set on these boards are
too conservative and will cause the driver to stop the net device
erroneously in some systems.Based on a review of the chip datasheets and advice from the designer
of these boards:- Raise the maximum board temperatures to the specified maximum ambient
temperatures for their PHYs plus the expected temperature bias of the
board
- Raise the maximum controller temperature to 90 degrees
- Lower the minimum temperatures to 0 degrees
- Widen the voltage tolerances to at least +/- 10%Signed-off-by: Ben Hutchings
