2008-07-23ide: add ide_host_add() helperBartlomiej Zolnierkiewicz
Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(), then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some host drivers to use it. While at it: * Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c, macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value. * -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c and pmac.c * -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c * -1 -> -ENOMEM in ide-pnp.c Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-23ide: add struct ide_host (take 3)Bartlomiej Zolnierkiewicz
* Add struct ide_host which keeps pointers to host's ports. * Add ide_host_alloc[_all]() and ide_host_remove() helpers. * Pass 'struct ide_host *host' instead of 'u8 *idx' to ide_device_add[_all]() and rename it to ide_host_register[_all](). * Convert host drivers and core code to use struct ide_host. * Remove no longer needed ide_find_port(). * Make ide_find_port_slot() static. * Unexport ide_unregister(). v2: * Add missing 'struct ide_host *host' to macide.c. v3: * Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/) (Noticed by Stephen Rothwell).

2008-07-23ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)Bartlomiej Zolnierkiewicz
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use it instead of calling ide_init_port_hw() directly. [ However if host has > 1 port we must still set hwif->chipset to hint consecutive ide_find_port() call that the previous slot is occupied. ] * Unexport ide_init_port_hw(). v2: * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c. (Suggested by Geert Uytterhoeven) * Better patch description. v3: * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell) There should be no functional changes caused by this patch.

2008-06-10ide: fix host drivers missing hwif->chipset initializationBartlomiej Zolnierkiewicz
ide_find_port() now depends on ->chipset being set for occupied ide_hwifs[] slots so all host drivers have to initialize hwif->chipset properly.

* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags and set them in ht6560, cmd640, cmd64x and sc1200 host drivers. * Add set_pio_mode_abuse() for checking if host driver has a non-standard ->tuneproc() implementation and use it in do_special(). * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find the maximum PIO mode supported by the host), also add ide_set_max_pio() wrapper for ide_set_pio() to use for auto-tuning. Convert users of ->tuneproc to use ide_set{_max}_pio() where possible. This leaves only do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as a direct users of ->tuneproc. * Remove no longer needed ide_get_best_pio_mode() calls and printk-s reporting PIO mode selected from ->tuneproc implementations. * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const. * Remove stale comment from ide_config_drive_speed(). v2: * Fix "ata_" prefix (Noticed by Jeff). v3: * Minor cleanups/fixups per Sergei's suggestions. v4: * Fix compile problem in drivers/ide/pci/cmd640.c (Noticed by Andrew Morton). * Improve some ->set_pio_mode comments.

2005-07-27[PATCH] clean up inline static vs static inlineJesper Juhl
`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
