2008-03-19async_tx: avoid the async xor_zero_sum path when src_cnt > device->max_xorDan Williams1-1/+1
If the channel cannot perform the operation in one call to ->device_prep_dma_zero_sum, then fallback to the xor+page_is_zero path. This only affects users with arrays larger than 16 devices on iop13xx or 32 devices on iop3xx.

2008-03-19fsldma: Fix the DMA halt when using DMA_INTERRUPT async_tx transfer.Zhang Wei2-0/+31
The DMA_INTERRUPT async_tx is a NULL transfer, thus the BCR(count register) is 0. When the transfer started with a byte count of zero, the DMA controller will triger a PE(programming error) event and halt, not a normal interrupt. I add special codes for PE event and DMA_INTERRUPT async_tx testing.

begin_undock() is only called when triggered via a acpi notify handler (pressing the undock button on the dock station), but complete_undock() is always called after the eject. So if a undock is triggered through a sysfs write, the flag DOCK_UNDOCKING has to be set for the dock station, too. Otherwise this will freeze the system hard.

Acer BIOS has a bug which is exposed when a dead battery is present. The package template that is used to describe battery status is over-written with sane values when the battery is live. But when the batter is dead, a bogus reference in the template is used. In this case, Linux returns a fault, when instead it should simply return that it doesn't know the missing value. http://bugzilla.kernel.org/show_bug.cgi?id=8573 http://bugzilla.kernel.org/show_bug.cgi?id=10202 Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
2008-03-18pciehp: don't enable slot unless forcedMark Lord1-1/+1
This fixes a 2.6.25 regression reported by Alex Chiang. Invoke pciehp_enable_slot() at startup only when pciehp_force=1. Some HP equipment apparently cannot cope with it otherwise. This restores the (previously working) 2.6.24 behaviour here, while allowing machines that need a kick to use pciehp_force=1. This was the original design back in October 2007, but Kristen suggested we try without it first: Kristen Carlson Accardi wrote: >I think it would be ok to try allowing the slot to be enabled when not >using pciehp_force mode. We can wrap it later if it proves to break things This ended up breaking one of Alex's setups, so it's time to put the wrapper back in now.

V . interrupt is delivered . skb_recv_done does atomic napi test, ok some waiting disable_cb is called->check fails->bang! . poll would do napi check poll would do disable_cb The fix is to let enable_cb not disable the interrupt again, but expect the caller to do the cleanup if it returns false. In that case, the interrupt is only disabled, if the napi test_set_bit was successful.
