* sgiioc4: fix messagesSergei Shtylylov2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix several issues with the log messages printed by ide_dma_sgiioc4() and sgiioc4_ide_setup_pci_device(): - IOC4 registers are memory-mapped but the "BM-DMA at" format corresponds to I/O mapped registers; - "%p" format specifiers and type casts used to print non-pointer values; - using KERN_INFO log level for the error message; - 'hwif->name' printed as drive's name. While at it, also: - return more fitting -EBUSY if request_mem_region() fails; - make the error message style consistent; - fix indentation, put the printk() facility and message on the same line; - use comparisions with NULL instead of ! operator..

* sgiioc4: sgiioc4_read_status drive busy check fixSergei Shtylylov2008-10-13
| | | | | | | | | | | Fix the drive non-busy criterion used by sgiioc4_read_status(): neither of the bits it expects to be set guarantees that the drive is not busy (and might be interrupting), only the BSY bit itself being zero gurantees that. While at it, use ATA_BUSY instead of hardcoded value everywhere...

* vfs: Use const for kernel parser tableSteven Whitehouse2008-10-13
| | | | | | | | | | | | | | This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.
