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.
