2008-02-02ide: remove redundant init_hwif_default() call from ide_register_hw()Bartlomiej Zolnierkiewicz
ide_init_port_hw() call overrides setup done by init_hwif_default(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide: remove redundant hwif->present check from ide_register_hw()Bartlomiej Zolnierkiewicz
We check earlier for hwif->present and call ide_unregister() if necessary (after ide_unregister() hwif->present will be always cleared). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: bump driver version numberBorislav Petkov
Acknowledge major ide-floppy code refactoring and cleanup by bumping the driver version number. Also, remove a wrong comment. Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

such as ERROR: switch and case should be at the same indent ERROR: need spaces around that '=' (ctx:VxV) ERROR: trailing statements should be on next line WARNING: no space between function name and open parenthesis '(' WARNING: printk() should include KERN_ facility level ERROR: That open brace { should be on the previous line ERROR: use tabs not spaces ERROR: do not use assignment in if condition WARNING: braces {} are not necessary for single statement blocks ERROR: need space after that ',' (ctx:VxV) WARNING: line over 80 characters ERROR: do not use assignment in if condition ... and so on.

2008-02-02ide-floppy: remove atomic test_*bit macrosBorislav Petkov
..and replace them with flag enums. Bart: - fix idefloppy_media_changed() return value Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: remove unused flag PC_ABORTBorislav Petkov
This flag was never being set in the code so remove it. By the way, the code in the second patch was being executed unconditionally, i.e. in case pc->retries > IDEFLOPPY_MAX_PC_RETRIES is true (actually that is the only case when the outer if-test passed), !test_bit(PC_ABORT, &pc->flags) was always true so the comment is now incorrect and has to go.

2008-02-02ide-floppy: remove IDEFLOPPY_DEBUG_INFOBorislav Petkov
This info is already available through ioctl() and /proc Bart: - dump 'gcw.packet_size' for unsupported packet sizes Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: remove unused IDEFLOPPY_USE_READ12Borislav Petkov
This flag is not being set anywhere in the driver so it can go. Bart: - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: merge idefloppy_{input,output}_buffersBorislav Petkov
We merge idefloppy_{input,output}_buffers() into idefloppy_io_buffers() by introducing a 4th arg. called direction. According to its value we atapi_input_bytes() or atapi_output_bytes(). Also, this simplifies the interrupt handler logic a bit. Finally, rename idefloppy_io_buffers() to ide_floppy_io_buffers().

2008-02-02ide-floppy: use an xfer_func_t and io_buf_t typedefs in order to unify rwBorislav Petkov
Also, move xfer_func_t typedef to the ide.h since it is used by two drivers now (more coming). Bart: - use __func__ while at it Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: mv idefloppy_{should_,}report_errorBorislav Petkov
In addition to shortening the function name, move the printk-call into the function thereby saving some code lines. Also, make the function out_of_line since it is not on a performance critical path. Finally, rename the reworked function to ide_floppy..(). Bart: - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: report DMA handling in idefloppy_pc_intr() properlyBorislav Petkov
Bart: - use 'hwif' instead of 'HWIF(drive)' - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: factor out ioctl handlers from idefloppy_ioctl()Borislav Petkov
By passing idefloppy_floppy_t *floppy to the factored out functions, we get rid of (almost) all local vars so stack usage should be at minimum here. Also, we merge idefloppy_begin_format() into idefloppy_format_start() since it is its only user. Also, rename idefloppy_format_start() to idefloppy_format_unit(). Finally, rename the reworked functions to ide_floppy..().

2008-02-02ide-floppy: remove struct idefloppy_capacity_descriptorBorislav Petkov
Also, - remove the accompanying 4 byte idefloppy_capacity_header. - rename functions from idefloppy_... to ide_floppy_... after cleanup. - simplify loop in ide_floppy_get_capacity() by reversing if-test condition logically. - finally, fix white space and checkpatch.pl issues Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove struct idefloppy_request_sense_resultBorislav Petkov
While at it, collapse idefloppy_analyze_error() into idefloppy_request_sense_callback() since the latter was its only user. Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove struct idefloppy_capabilities_pageBorislav Petkov
This change is rather temporary and is in preparation of using generic commands as is the case with ide-cd and the uniform cdrom layer (i.e. init_cdrom_command()) However, before this happens, we'll have to remove all typedefs and teach idefloppy_create_mode_sense_cmd() to work directly on u8 buffers. Also, since idefloppy_get_capability_page() was used to read only the sfrp bit, rename the latter so that the name reflects what it does.

2008-02-02ide-floppy: cleanup and unify debugging macro callsBorislav Petkov

2008-02-02ide-floppy: disambiguate function namesBorislav Petkov
There were two almost identical function names in ide-floppy.c, which makes their distinction almost impossible. While ide_floppy_release() cleans up the object after the last reference to it has been dropped, idefloppy_release() is the blkdev .release method from struct block_device_operations which releases that last reference. Rename ide_floppy_release() to idefloppy_cleanup_obj() in order to make its purpose more clear. There should be no functionality change resulting from this patch.

Replace the ide-floppy packet commands opcode defines with the generic ones. Add a missing GPCMD_WRITE_12 (opcode 0xaa) to the generic ones in cdrom.h.

2008-02-02ide: add ->cable_detect method to ide_hwif_tBartlomiej Zolnierkiewicz
* Add ->cable_detect method to ide_hwif_t. * Call the new method in ide_init_port() if: - the host supports UDMA modes > UDMA2 ('hwif->ultra_mask & 78') - DMA initialization was successful (if hwif->dma_base is not set ide_init_port() sets hwif->ultra_mask to zero) - "idex=ata66" is not used ('hwif->cbl != ATA_CBL_PATA40_SHORT') * Convert PCI host drivers to use ->cable_detect method.

* Remove 'struct pci_dev *dev' argument from ide_hwif_setup_dma(). * Un-static ide_hwif_setup_dma() and add CONFIG_BLK_DEV_IDEDMA_PCI=n version. * Add 'const struct ide_port_info *d' argument to ide_device_add[_all](). * Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(), move it to ide-probe.c and call it in in ide_device_add_all() instead of ide_pci_setup_ports(). * Move ->mate setup to ide_device_add_all() from ide_port_init(). * Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable ->autotune currently. * Setup hwif->chipset in ide_init_port() but iff pi->chipset is set (to not override setup done by ide_hwif_configure()). * Add ETRAX host handling to ide_device_add_all(). * cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n. * pmac.c: make pmac_ide_setup_dma() return an error value and move DMA masks setup to pmac_ide_setup_device(). * Add 'struct ide_port_info' instances to legacy host drivers, pass them to ide_device_add() calls and then remove open-coded ports initialization.

2008-02-01PCI: Remove users of pci_enable_device_bars()Benjamin Herrenschmidt
This patch converts users of pci_enable_device_bars() to the new pci_enable_device_{io,mem} interface. The new API fits nicely, except maybe for the QLA case where a bit of code re-organization might be a good idea but I prefer sticking to the simple patch as I don't have hardware to test on. I'll also need some feedback on the cs5520 change. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Add BUG_ON(hwif->present) at the start of ide_probe_port(). * Move hwif_register() call (along with setting hwif->present) from ide_probe_port() to ide_device_add_all().
