2008-04-26ide-cd: remove the internal 64k bufferBorislav Petkov
This removes the internal ide-cd buffer and falls back to read-ahead block layer capabilities. Thorough testing (cd burning, dvd read, raw read) gives with the bufferless mode marginally better performance in addition to simplified code. bufferless: dd: reading `/dev/hdc': Input/output error 6238+0 records in 6238+0 records out 204406784 bytes (204 MB) copied, 259.891 s, 787 kB/s real 4m21.598s user 0m0.014s sys 0m0.744s with the old buffer (2.6.25-rc1): dd: reading `/dev/hdc': Input/output error 6238+0 records in 6238+0 records out 204406784 bytes (204 MB) copied, 262.893 s, 778 kB/s real 4m22.938s user 0m0.009s sys 0m0.771s Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-26ide: make ide_pci_check_iomem() actually workSergei Shtylyov
This function didn't actually check if a given BAR is in I/O space because of using the bogus PCI_BASE_ADDRESS_IO_MASK (which equals ~3) to test the resource flags instead of IORESOURCE_IO -- fix this, make ide_hwif_configure() check the results failing if necessary, and move the printk() call to the failure path.
