* sh: prevent the DMA driver from unloading, while in useGuennadi Liakhovetski2010-05-221-0/+1
| | | | | | | | This prevents the driver from unloading, while it is in use. Unloading of the driver, while its DMA channels are held, leads to a kernel Oops. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fix Oops in the serial SCI driverGuennadi Liakhovetski2010-05-221-2/+3

* sh: allow platforms to specify SD-card supported voltagesGuennadi Liakhovetski2010-05-222-1/+6
| | | | | | | | | Boards can have different supplied voltages on different SD card slots. This information has to be passed down to the SD/MMC driver.

* tmio: add a platform flag to disable card write-protection detectionGuennadi Liakhovetski2010-05-222-1/+8
| | | | | | | | | | Write-protection status is not always available, e.g., micro-SD cards do not have a write-protection switch at all. This patch adds a flag to let platforms force tmio_mmc to consider the card writable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't put struct file on the stack as it takes up quite a lot of space and violates lifetime rules for struct file. Rather than calling afs_readpage() indirectly from the directory routines by way of read_mapping_page(), split afs_readpage() to have afs_page_filler() that's given a key instead of a file and call read_cache_page(), specifying the new function directly. Use it in afs_readpages() as well. Also make use of this in afs_mntpt_check_symlink() too for the same reason.

| * Ban ecryptfs over ecryptfsAl Viro2010-05-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a seriously simplified patch from Eric Sandeen; copy of rationale follows: === mounting stacked ecryptfs on ecryptfs has been shown to lead to bugs in testing. For crypto info in xattr, there is no mechanism for handling this at all, and for normal file headers, we run into other trouble: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffffa015b0b3>] ecryptfs_d_revalidate+0x43/0xa0 [ecryptfs] ... There doesn't seem to be any good usecase for this, so I'd suggest just disallowing the configuration. Based on a patch originally, I believe, from Mike Halcrow. === Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
