2007-01-09[PATCH] i2c/pci: fix sis96x smbus quirk once and for allMark M. Hoffman
The sis96x SMBus PCI device depends on two different quirks to run in a specific order. Apart from being fragile, this was found to actually break on (at least) recent FC4, FC5, and FC6 kernels. This patch fixes the quirks so that they work without relying on the compiler and/or linker to put them in any specific order. http://lists.lm-sensors.org/pipermail/lm-sensors/2006-April/015962.html https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189719 I tested this patch.

Changeset 740b5706b9c4b3767f597b3ea76654c6f2a800b2 moved the protecting spinlock from __cpcmd to cpcmd. Therefore vmcp can no longer use __cpcmd, instead we have to use cpcmd. Signed-off-by: Christian Borntraeger <cborntra@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2007-01-09[S390] cio: use barrier() in stsch_reset.Heiko Carstens
Use barrier() in stsch_reset() instead of duplicating the stsch() inline assembly and adding "memory" to the clobberlist. Pointed out by Chuck Ebbert. Real fix would be to add a fixup section to the stsch() and extend the basic program check handler so it searches the exception tables in case of a program check.

2007-01-05[PATCH] connector: some fixes for ia64 unaligned access errorsErik Jacobson
On ia64, the various functions that make up cn_proc.c cause kernel unaligned access errors. If you are using these, for example, to get notification about all tasks forking and exiting, you get multiple unaligned access errors per process. Use put_unaligned() in the appropriate palces to fix this.

2007-01-05[PATCH] hpt37x: Two important bug fixesAlan
The HPT37x driver very carefully handles DMA completions and the needed fixups are done on pci registers 0x50 and 0x52. This is unfortunate because the actual registers are 0x50 and 0x54. Fixing this offset cures the second channel problems reported. Secondly there are some problems with the HPT370 and certain ATA drives. The filter code however only filters ATAPI devices due to a reversed type check.

2007-01-05[PATCH] KVM: MMU: Shadow page table cachingAvi Kivity
Define a hashtable for caching shadow page tables. Look up the cache on context switch (cr3 change) or during page faults. The key to the cache is a combination of - the guest page table frame number - the number of paging levels in the guest * we can cache real mode, 32-bit mode, pae, and long mode page tables simultaneously. this is useful for smp bootup. - the guest page table table * some kernels use a page as both a page table and a page directory. this allows multiple shadow pages to exist for that page, one per level - the "quadrant" * 32-bit mode page tables span 4MB, whereas a shadow page table spans 2MB. similarly, a 32-bit page directory spans 4GB, while a shadow page directory spans 1GB. the quadrant allows caching up to 4 shadow page tables for one guest page in one level. - a "metaphysical" bit * for real mode, and for pse pages, there is no guest page table, so set the bit to avoid write protecting the page.
