* ps3/block: Replace mtd/ps3vram by block/ps3vramGeert Uytterhoeven2009-03-133-776/+0
| | | | | | | | | | | | | | | Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block device driver. The ps3vram driver exposes unused video RAM on the PS3 as a block device suitable for storage or swap. Fast data transfer is achieved using a local cache in system RAM and DMA transfers via the GPU. The new driver is ca. 50% faster for reading, and ca. 10% for writing.

* mtd: physmap: fix NULL pointer dereference in error pathAtsushi Nemoto2009-03-101-8/+11
| | | | | | | | | | | | | | | | commit e480814f138cd5d78a8efe397756ba6b6518fdb6 ("[MTD] [MAPS] physmap: fix wrong free and del_mtd_{partition,device}") introduces a NULL pointer dereference in physmap_flash_remove when called from the error path in physmap_flash_probe (if map_probe failed). Call del_mtd_{partition,device} only if info->cmtd was not NULL.

* mtd_dataflash: fix probing of AT45DB321C chips.Will Newton2009-03-101-1/+2
| | | | | | | | | | | | | | | Commit 771999b65f79264acde4b855e5d35696eca5e80c ("[MTD] DataFlash: bugfix, binary page sizes now handled") broke support for probing AT45DB321C flash chips. These chips do not support the "page size" status bit, so if we match the JEDEC id return early.

Fix this by adding the compat_ioctl method. Also, UBI serializes all ioctls, so more than one ioctl at a time is not a problem. Amd UBI does not seem to depend on anything else, so use unlocked_ioctl instead of ioctl (no BKL needed).
