2008-07-03ARM: OMAP: DMTimer: Optimize by adding load and startRichard Woodruff
This patch optimizes the timer load and start sequence. By combining the load and start a needless posted wait can be removed from the system timer execution path. * Before patch register writes are taking up .078% @ 500MHz during idle.

2008-07-03ARM: OMAP: DMTimer: Use posted modeRichard Woodruff
This patch adds the use of write posting for the timer. Previously, every write could lock the requestor for almost 3x32KHz cycles. This patch only synchronizes before writes and reads instead of after them and it does it on per register basis. Doing it this way there is some chance to hide some of the sync latency. It also removes some needless reads when non-posted mode is there. With out this fix the read/writes take almost 2% CPU load @500MHz just waiting on tick timer registers. Also define new 34xx only registers. Signed-off-by: Richard Woodruff <r-woodruff2@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

When scheduled swaps occur, we need to blit between front & back buffers. If the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit, but only on 965 chips, since it will cause corruption on pre-965 (e.g. 945).

2008-07-02PCI: acpiphp: cleanup notify handler on all root bridgesAlex Chiang
During the development of the physical PCI slot patch series, Gary Hade kept on reporting strange oopses due to interactions between pci_slot and acpiphp. http://lkml.org/lkml/2007/11/28/319 find_root_bridges() unconditionally installs handle_hotplug_event_bridge() as an ACPI_SYSTEM_NOTIFY handler for all root bridges. However, during module cleanup, remove_bridge() will only remove the notify handler iff the root bridge had a hot-pluggable slot directly underneath. That is: root bridge -> hotplug slot But, if the topology looks like either of the following: root bridge -> non-hotplug slot root bridge -> p2p bridge -> hotplug slot Then we currently do not remove the notify handler from that root bridge. This can cause a kernel oops if we modprobe acpiphp later and it gets loaded somewhere else in memory. If the root bridge then receives a hotplug event, it will then attempt to call a stale, non-existent notify handler and we blow up. Much thanks goes to Gary Hade for his persistent debugging efforts.

2008-07-02PCI: Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.Benjamin Li
For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the VPD end tag will hang the device. This problem was initially observed when a vpd entry was created in sysfs ('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry will dump 32k of data. Reading a full 32k will cause an access beyond the VPD end tag causing the device to hang. Once the device is hung, the bnx2 driver will not be able to reset the device. We believe that it is legal to read beyond the end tag and therefore the solution is to limit the read/write length. A majority of this patch is from Matthew Wilcox who gave code for reworking the PCI vpd size information. A PCI quirk added for the Broadcom NIC's to limit the read/write's.
