2009-04-18Remove 'recurse into child resources' logic from 'reserve_region_with_split()'Linus Torvalds1-34/+12
This function is not actually used right now, since the original use case for it was done with insert_resource_expand_to_fit() instead. However, we now have another usage case that wants to basically do a "reserve IO resource, splitting around existing resources", however that one doesn't actually want the "recurse into the conflicting resource" logic at all. And since recursing into the conflicting resource was the most complex part, and isn't wanted, just remove it. Maybe we'll some day want both versions, but we can just resurrect the logic then.

2009-04-18PM/Hibernate: Fix memory shrinkingRafael J. Wysocki1-2/+3
Commit d979677c4c0 ("mm: shrink_all_memory(): use sc.nr_reclaimed") broke the memory shrinking used by hibernation, becuse it did not update shrink_all_zones() in accordance with the other changes it made. Fix this by making shrink_all_zones() update sc->nr_reclaimed instead of overwriting its value.

2009-04-18hpt366: fix HPT370 DMA timeoutsSergei Shtylyov1-1/+3
The big driver change in 2.4.19-rc1 introduced a regression for many HPT370[A] chips -- DMA stopped to work completely, only causing endless timeouts... The culprit has been identified (at last!): it turned to be the code resetting the DMA state machine before each transfer. Stop doing it now as this counter- measure has clearly caused more harm than good. This should fix the kernel.org bug #7703.

Some VIA chipsets will reset the DEV bit after IEN changes on ctl. Our optimised write path avoids doing this but we need to remove the optimisation on these devices.

2009-04-17sata_mv: workaround for multi_count errata sata24Mark Lord1-2/+42
Workaround for errata SATA#24 in sata_mv. This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.
