* Set taskfile flags for REQ_TYPE_ATA_TASKFILE requests before adding the request to the queue. * Cleanup execute_drive_cmd(). * Remove unnecessary writes to HOB taskfile registers when using LBA48 disk for the following cases: - Power Management requests (WIN_FLUSH_CACHE[_EXT], WIN_STANDBYNOW1, WIN_IDLEIMMEDIATE commands) - special commands (WIN_SPECIFY, WIN_RESTORE, WIN_SETMULT) - Host Protected Area support (WIN_READ_NATIVE_MAX, WIN_SET_MAX) - /proc/ide/ SMART support (WIN_SMART with SMART_ENABLE, SMART_READ_VALUES and SMART_READ_THRESHOLDS subcommands) - write cache enabling/disabling in ide-disk (WIN_SETFEATURES with SETFEATURES_{EN,DIS}_WCACHE) - write cache flushing in ide-disk (WIN_FLUSH_CACHE[_EXT]) - acoustic management in ide-disk (WIN_SETFEATURES with SETFEATURES_{EN,DIS}_AAM) - door (un)locking in ide-disk (WIN_DOORLOCK, WIN_DOORUNLOCK) - /proc/ide/hd?/identify support (WIN_IDENTIFY) - ACPI _GTF taskfiles Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Use IDE_TFLAG_LBA48 for REQ_TYPE_ATA_TASKFILE requests in ide_end_drive_cmd() to decide whether we need to read HOB taskfile registers. * Update execute_drive_cmd() accordingly.

* Add IDE_TFLAG_OUT_DEVICE taskfile flag to indicate the need of writing the Device register and handle it in ide_tf_load().

* Rename 'args' variable in 'if (rq->cmd_type == REQ_TYPE_ATA_TASKFILE)' block to 'task'. * execute_drive_cmd() is used only for REQ_TYPE_ATA_{CMD,TASK,TASKFILE} so we can move the common code out from 'if (rq->cmd_type == REQ_TYPE_ATA_CMD)' and 'if (rq->cmd_type == REQ_TYPE_ATA_TASK)' blocks.

Move loading of IDE_NSECTOR_REG from ide_cmd() to execute_drive_cmd() (load the IDE_NSECTOR_REG just after IDE_FEATURE_REG). This also allows us to drop 'nsect' argument from ide_cmd() and simplify execute_drive_cmd() code for REQ_TYPE_ATA_CMD case a bit. It shouldn't affect anything (just a usual paranoia to separate changes which change the way in which hardware is accessed from code cleanups).

* pmac_ide_init_hwif_ports() can be called by ide_init_hwif_ports() (through ppc_ide_md.ide_init_hwif hook) for non IDE PMAC interfaces. If this is the case the hw->io_ports[] should be already setup by ide_init_hwif_ports()->ide_std_init_ports() so remove redundant code from pmac_ide_init_hwif_ports().

Based on the earlier work by Tejun Heo. * Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile() function to the callers. * Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming from ide_taskfile_ioctl(). Check it instead of ->tf_out_flags.all. * Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load IDE data register in ide_tf_load(). * Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load particular IDE taskfile registers in ide_tf_load(). * Update do_rw_taskfile() and ide_tf_load() users to set respective IDE_TFLAG_OUT_* taksfile flags. * Add task_dma_ok() helper. * Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load(). * Use do_rw_taskfile() in flagged_taskfile(). * Remove no longer needed 'tf_out_flags' field from ide_task_t.

Currently it's possible to ide-cd to set an incorrect blocksize by reading garbage if the drive is dead: ide_cd_probe() -> cdrom_read_toc() -> cdrom_read_capacity() -> cdrom_queue_packet_command() -> ide_do_drive_cmd() -> ide_do_request() -> start_request() on start_request(): /* bail early if we've exceeded max_failures */ if (drive->max_failures && (drive->failures > drive->max_failures)) { goto kill_rq; } (...) kill_rq: ide_kill_rq(drive, rq); return ide_stopped; ide_kill_rq() and the next calls won't set REQ_FAILED on rq->cmd_flags and thus cdrom_queue_packet_command() won't return an error. then: stat = cdrom_queue_packet_command(drive, &req); if (stat == 0) { *capacity = 1 + be32_to_cpu(capbuf.lba); *sectors_per_frame = be32_to_cpu(capbuf.blocklen) >> SECTOR_BITS; } cdrom_read_capacity() ends believing capbuf is valid but in fact it's just uninitialized data. back to cdrom_read_toc(): /* Try to get the total cdrom capacity and sector size. */ stat = cdrom_read_capacity(drive, &toc->capacity, §ors_per_frame, sense); if (stat) toc->capacity = 0x1fffff; set_capacity(info->disk, toc->capacity * sectors_per_frame); /* Save a private copy of te TOC capacity for error handling */ drive->probed_capacity = toc->capacity * sectors_per_frame; blk_queue_hardsect_size(drive->queue, sectors_per_frame << SECTOR_BITS); that will set drive->queue->hardsect_size to be the random value. hardsect_size is used to calculate inode->i_blkbits. later on, on a read path: void create_empty_buffers(struct page *page, unsigned long blocksize, unsigned long b_state) { struct buffer_head *bh, *head, *tail; head = alloc_page_buffers(page, blocksize, 1); bh = head; do { bh->b_state |= b_state; tail = bh; bh = bh->b_this_page; } while (bh); tail->b_this_page = head; alloc_page_buffers() will return NULL if blocksize > 4096. blocksize is calculed based on inode->i_blkbits. that will trigger a null dereference on create_empty_buffers().

This can be broken down into these major areas: - Documentation updates (language translations and fixes, as well as kobject and kset documenatation updates.) - major kset/kobject/ktype rework and fixes. This cleans up the kset and kobject and ktype relationship and architecture, making sense of things now, and good documenation and samples are provided for others to use. Also the attributes for kobjects are much easier to handle now. This cleaned up a LOT of code all through the kernel, making kobjects easier to use if you want to. - struct bus_type has been reworked to now handle the lifetime rules properly, as the kobject is properly dynamic. - struct driver has also been reworked, and now the lifetime issues are resolved. - the block subsystem has been converted to use struct device now, and not "raw" kobjects. This patch has been in the -mm tree for over a year now, and finally all the issues are worked out with it. Older distros now properly work with new kernels, and no userspace updates are needed at all. - nozomi driver is added. This has also been in -mm for a long time, and many people have asked for it to go in. It is now in good enough shape to do so. - lots of class_device conversions to use struct device instead. The tree is almost all cleaned up now, only SCSI and IB is the remaining code to fix up... * git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (196 commits) Driver core: coding style fixes Kobject: fix coding style issues in kobject c files Kobject: fix coding style issues in kobject.h Driver core: fix coding style issues in device.h spi: use class iteration api scsi: use class iteration api rtc: use class iteration api power supply : use class iteration api ieee1394: use class iteration api Driver Core: add class iteration api Driver core: Cleanup get_device_parent() in device_add() and device_move() UIO: constify function pointer tables Driver Core: constify the name passed to platform_device_register_simple driver core: fix build with SYSFS=n sysfs: make SYSFS_DEPRECATED depend on SYSFS Driver core: use LIST_HEAD instead of call to INIT_LIST_HEAD in __init kobject: add sample code for how to use ksets/ktypes/kobjects kobject: add sample code for how to use kobjects in a simple manner. kobject: update the kobject/kset documentation kobject: remove old, outdated documentation. ...

If the node we're booting on doesn't have memory, bootstrapping kmalloc() caches resorts to fallback_alloc() which requires ->nodelists set for all nodes. Fix that by calling set_up_list3s() for CACHE_CACHE in kmem_cache_init(). As kmem_getpages() is called with GFP_THISNODE set, this used to work before because of breakage in 2.6.22 and before with GFP_THISNODE returning pages from the wrong node if a node had no memory. So it may have worked accidentally and in an unsafe manner because the pages would have been associated with the wrong node which could trigger bug ons and locking troubles.
