The pdflush kernel threads can lead to an unbounded chain of thread-creations which can overflow the kernel stacks because we didn't uses to reset the stack on kernel thread-creation. We do now. Reported by Andreas Schwab, tracked down with help from Keith Owens.

This patch changes the I/O SAPIC code to cache the low 32 bits of the mask word in kernel memory. This greatly speeds up mask_irq() and unmask_irq(). Normally, these operations are not on the speed-critical path of the kernel but with certain devices drivers (including users-level device- drivers) they can become performance-critical.

- fix bug in pfm_unload(), not allowed when not on correct CPU for system-wide - some perf/cleanup in overflow handler - fix reset_pmds to be on a per PMD basis on counter overflow rather than global - remove timing debug code on messages - no kernel info leak on PFM_END_MSG - remove double-store on reg_flags for pfm_write_pmcs, pfm_write_pmds - on restart reset_pmds is 0 by default - cleanup useless macros - cleanup some debug prints - added ability to remove debug code - streamlined sys_perfmonctl(), pfm_read_pmds(), pfm_write_*() - added current->tgid to default format sample header by using one reserved field

The problem was that IDE-disks on machines with IDE harddisks, memory above 4GB and no hardware I/O TLB would go BUG_ON() in blk_queue_bounce_limit() because the IDE-controller could only address 4GB of memory and that was much less than BLK_BOUNCE_ISA (which is equal to ISA_DMA_THRESHOLD). Note that the problem does NOT trigger with CD-ROMs, which always uses the software I/O TLB (and hence bounce-buffers) on such machines. The best fix seems to be to simply lower ISA_DMA_THRESHOLD to 4GB-1 since that will ensure that the IDE block layer allocates memory with GFP_DMA, which will minimize bounce buffering.

Tighten AFS partition checks: - check footer checksum. - check that the image name is NUL terminated. - return error from mtd->read intact. This prevents us finding bogus AFS partitions.

This makes it possible for people like me with a small-mem G5 to enable the DART. I see two reasons for wanting to do so: 1. To debug/test DART/iommu code itself (small audience, including myself). 2. To debug drivers on small-mem machines, since bad pci_map*() usage will be punished (possibly larger audience).

This patch fixes a bug which could cause do_softirq() to be called at the wrong time (from do_IRQ()) or without pre-emption protection.

This makes GregKH happy by removing the device name from the device.bus_id field (and replacing it with a "name" sysfs attribute). It also renames the parent device from "vdevice" to "vio", making the /sys/bus and /sys/devices hierarchies consistent.

Add documentation for the above two functions. Allow a NULL name to be passed to amba_request_regions. In this case, we use the driver's name associated with the device.

The old sysctl PM interface has been replaced by the driver models interface. This has been gone for a while in the -rmk tree and no one complained, so there's no point keeping it around.

- use dev_dbg for device-centric debugging messages - use pr_debug for general debugging messages - use dmapools instead of pcipools - use NULL rather than 0 for NULL pointers - use enum dma_data_direction rather than int - use DMA_* direction definitions rather than PCI_DMA_* - only check for sane DMA direction on mapping functions, but check that DMA direction matches when unmapping/syncing.

Thanks to Adrian Bunk. Remove kernel 2.0 #ifdef's from arm code, and move MODULE_* to the end of the file. Add an appropriate MODULE_LICENSE().

This patch makes it possible to select the hugetlbfs page size at boot-time, rather than at compile-time. We believe we have resolved all the remaining issues. All critical speed path has been taken care of, i.e., vhpt handler and context switch. There should be no performance penalty with this dynamic hugetlb page size feature. We would like to thank Jack Steiner for his initiative on this feature and his initial cool working patch.

Currently, sinit_max_init_timeo is treated as the maximum timeout value for INIT retransmissions and the INIT process is aborted when the timeout reaches this value. But as per the SCTP sockets API draft, sinit_max_init_timeo only limits the timeout. The INIT process should be aborted only after MAX_INIT_RETRANSMITS.
