2007-10-19pdc202xx_old: remove broken SWDMA supportBartlomiej Zolnierkiewicz
Documentation doesn't mention SWDMA and moreover all timings used for SWDMA modes were over-clocked when compared to ATA spec. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-19ide: add IDE_HFLAG_NO_LBA48 and IDE_HFLAG_NO_LBA48_DMA host flagsBartlomiej Zolnierkiewicz
Add IDE_HFLAG_NO_LBA48[_DMA] host flags, use it instead of hwif->no_lba48[_dma] and then remove no longer needed hwif->no_lba48[_dma]. As a side-effect this change fixes hwif->no_lba48_dma not being restored by ide_hwif_restore().

2007-10-19ide: remove ->init_setup_dma from ide_pci_device_t (take 2)Bartlomiej Zolnierkiewicz
* Make ide_pci_device_t.host_flags u32 and add IDE_HFLAG_CS5520 host flag. * Pass ide_pci_device_t *d to setup-pci.c::ide_get_or_set_dma_base() and use d->name instead of hwif->cds->name. * Set IDE_HFLAG_CS5520 host flag in cs5520 host driver and use it in ide_get_or_set_dma_base() to find out which PCI BAR to use, remove no longer needed cs5520.c::cs5520_init_setup_dma() and ide_pci_device_t.init_setup_dma. This fixes PCI bus-mastering not being checked for CS5510/CS5520 hosts. v2: * It is wrong to check simplex bits on CS5510/CS5520 as v1 did. (Noticed by Alan).

2007-10-19ide: add IDE_HFLAG_BOOTABLE host flagBartlomiej Zolnierkiewicz
Add IDE_HFLAG_BOOTABLE host flag and IDE_HFLAG_OFF_BOARD define. Convert all host drivers using ide_pci_device_t to use IDE_HFLAG_{BOOTABLE,OFF_BOARD} instead of d->bootable and then remove no longer needed d->bootable. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-19ide: add IDE_HFLAG_NO_ATAPI_DMA host flagBartlomiej Zolnierkiewicz

2007-10-179p: fix bad kconfig cross-dependencyEric Van Hensbergen
This patch moves transport dynamic registration and matching to the net module to prevent a bad Kconfig dependency between the net and fs 9p modules. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-10-179p: soften invalidation in loose_modeEric Van Hensbergen
Loose mode in 9p utilizes the page cache without respecting coherency with the server. Any writes previously invaldiated the entire mapping for a file. This patch softens the behavior to only invalidate the region of the actual write. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-10-179p: attach-per-userLatchesar Ionkov
The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

2007-10-179p: Make transports dynamicEric Van Hensbergen
