2007-12-24[Blackfin] arch: Fix gpio label handlingMichael Hennerich
early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels. So we always have two zombies (allocated pin functions without labels) This happens before the initcalls - We now allocate memory statically. Define MAX_RESOURCES individually for each cpu.

2008-01-27[Blackfin] arch: fix bug - trap_tests fails to recover on some tests.Robin Getz
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3719 When the CPLBs get a miss, we do: - find a victim in the HW table - remove the victim - find the replacement in the software table - put it into the HW table. If we can't find a replacement in the software table, we accidently leave a duplicate in the HW table. This patch ensures that duplicate is marked as not valid. What we should do is find the replacement in the software table, before we find a victim in the HW table - but its too late in the release cycle to do that much restructuring of this code. Rather that duplicate code, connect Hardware Errors (irq5) into trap_c, so user space processes get killed properly. The rest of irq_panic() can be moved into traps.c (later) There is still a small corner case that causes problems when a pheriperal interrupt goes off a single cycle before a user space hardware error. This causes a kernel panic, rather than the user space process being killed. But, this checkin makes things work in 99.9% of the cases, and is a vast improvement from what is there today (which fails 100% of the time).

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>
