2008-01-26ide: fix final status check in drive_cmd_intr()Bartlomiej Zolnierkiewicz
Don't check for READY_STAT bit being set for PIO-in protocol (makes the final status check in drive_cmd_intr() match the one in task_in_intr()). Also fix function name reported by ide_error() call while at it. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-01-26ide: task_end_request() fixTejun Heo
task_end_request() modified to always call ide_end_drive_cmd() for taskfile requests. Previously, ide_end_drive_cmd() was called only when IDE_TFLAG_FLAGGED was set. Also, ide_dma_intr() is modified to use task_end_request(). Enables TASKFILE ioctls to get valid register outputs on successful completion.

2008-01-26ide: fix ->io_32bit race in ide_taskfile_ioctl()Tejun Heo
In ide_taskfile_ioctl(), there was a race condition involving drive->io_32bit. It was cleared and restored during ioctl requests but there was no synchronization with other requests. So, other requests could execute with the altered ->io_32bit setting or updated drive->io_32bit could be overwritten by ide_taskfile_ioctl(). This patch adds IDE_TFLAG_IO_16BIT flag to indicate to ide_pio_datablock() that 16-bit I/O is needed regardless of drive->io_32bit settting.

2008-01-26ide: remove broken disk byte-swapping supportBartlomiej Zolnierkiewicz
Remove broken disk byte-swapping support: - it can cause a data corruption on SMP (or if using PREEMPT on UP) - all data coming from disk are byte-swapped by taskfile_*_data() which results in incorrect identify data being reported by /proc/ide/ and IOCTLs - "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers (including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing) - byte-swapping is limited to PIO transfers (for working with TiVo disks on x86 machines using user-space solutions or dm-byteswap should result in much better performance because DMA can be used) For previous discussions please see: http://www.ussg.iu.edu/hypermail/linux/kernel/0201.0/0768.html http://lkml.org/lkml/2004/2/28/111 [ I have dm-byteswap device mapper target if somebody is interested (patch is for 2.6.4 though but I'll dust it off if needed). ] Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-01-26ide: don't try to unregister interfaces if 'initializing' in ide_register_hw()Bartlomiej Zolnierkiewicz
Host drivers using ide_register_hw() and 'initializing == 1': * ide-pnp - depends on ISA * ide_arm - ARM arch specific - initialized before all other host drivers * ide-cris - CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined - broken * ide-h8300 - H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI * buddha/q40/gayle/macide/falconide - M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI Since the only host drivers which probe interfaces before the above ones are: * ali14xx/dtc2278/ht6560b/qd65xx/umc8672 - depend on ISA - require IDE_ARCH_OBSOLETE_INIT=y to work * PCI ones - depend on PCI don't try to unregister interfaces if 'initializing == 1' in ide_register_hw() (it is possible that built-in host drivers will claim all IDE interfaces but later ide-pnp host driver will try to unregister them - this change fixes it). Also skip hwif->hold check if 'initializing == 1' since it is set only by: * pmac - PPC && PMAC specific => no ISA * au1xxx-ide - MIPS && SOC_AU1200 specific => no ISA and use ide_find_port() helper to find free ide_hwifs[] slot.

I left fixing ide-cris after "kill dma_on/dma_off_quietly() methods" patch because: * Currently this driver is broken: cris_dma_on() (returns 'int') is assigned to hwif->dma_host_on (returns 'void') so the driver won't build. * ->ide_dma_on method was missing so the driver OOPS-es on attempt to enable DMA. * drive->using_dma was never set/cleared so DMA wouldn't be used anyway. Unfortunately it seems that ide-cris stays broken even after this patch: * V10: <asm/arch-v10/ide.h> needs fixing - ide_init_default_hwifs() should be removed (IDE core no longer uses it) - same for ide_init_hwif_ports() and ide_default_{irq,io_base}() (they shouldn't be needed for ide-cris host driver) * V32: I'm unable to find a place which defines ETRAX_ARCH_V32 but I'm leaving fixing this to CRIS gurus. :) Cc: Mikael Starvik <starvik@axis.com> Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
