Update the ds1307 driver with alarm support for ds1337/ds1339. This uses the first alarm (there are two), and matches on seconds, minutes, hours, and day-of-month. Tested on ds1339. [dbrownell@users.sourceforge.net: add comments; fixup style, valid irq checks, debug dumps; lock; more careful IRQ shutdown; switch BCD2BIN to bcd2bin (and vice versa); ENOTTY not EINVAL.] Signed-off-by:

Validating clients with black magic register checks doesn't make much sense for new-style i2c driver and has been known to fail on valid NXP pcf8563 chips. This patch removes the client validation code. Signed-off-by:

Add a miscellaneous device to the autofs4 module for routing ioctls. This provides the ability to obtain an ioctl file handle for an autofs mount point that is possibly covered by another mount. The actual problem with autofs is that it can't reconnect to existing mounts. Immediately one things of just adding the ability to remount autofs file systems would solve it, but alas, that can't work. This is because autofs direct mounts and the implementation of "on demand mount and expire" of nested mount trees have the file system mounted on top of the mount trigger dentry. To resolve this a miscellaneous device node for routing ioctl commands to these mount points has been implemented in the autofs4 kernel module and a library added to autofs. This provides the ability to open a file descriptor for these over mounted autofs mount points. Please refer to Documentation/filesystems/autofs4-mount-control.txt for a discussion of the problem, implementation alternatives considered and a description of the interface.

The retry block in ecryptfs_readdir() has been in the eCryptfs code base for a while, apparently for no good reason. This loop could potentially run without terminating. This patch removes the loop, instead erroring out if vfs_readdir() on the lower file fails. Signed-off-by:

The I2O ioctls assume 32bits. In itself that is fine as they are old cards and nobody uses 64bit. However on LKML it was noted this assumption is also made for allocated memory and is unsafe on 64bit systems. Fixing this is a mess. It turns out there is tons of crap buried in a header file that does racy 32/64bit filtering on the masks. So we: - Verify all callers of the racy code can sleep (i2o_dma_[re]alloc) - Move the code into a new i2o/memory.c file - Remove the gfp_mask argument so nobody can try and misuse the function - Wrap a mutex around the problem area (a single mutex is easy to do and none of this is performance relevant) - Switch the remaining problem kmalloc holdout to use i2o_dma_alloc Cc: Markus Lidel <Markus.Lidel@shadowconnect.com> Cc: Vasily Averin <vvs@sw.ru> Signed-off-by:

Make the SPI external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked, and make the SPI core do its driver model initialization earlier so that's safe. SOC-integrated GPIOs are available starting very early -- often before initcalls start to run, or earily in arch_initcall() at latest -- so this improves consistency, letting more subsystems rely on GPIOs being usable by their own subsys_initcall() code.

Make the chip info structure data optional by providing reasonable defaults. Improve corresponding documentation, and highlight the drawback of not providing explicit chipselect control. DMA can determine appropriate dma_burst_size and thresholds automatically so use DMA even if dma_burst_size is not specified. Signed-off-by:

Add a pin configuration callback for the s3c24xx SPI driver, as there are several options depending on the channel and the chip in use. This is needed as the controller may not have been setup by the initial bootloader and the fact that the SPI controller gets reset over suspend/resume into slave mode but the GPIO function registers do not.

binfmt_script and binfmt_misc disallow recursion to avoid stack overflow using sh_bang and misc_bang. It causes problem in some cases: $ echo '#!/bin/ls' > /tmp/t0 $ echo '#!/tmp/t0' > /tmp/t1 $ echo '#!/tmp/t1' > /tmp/t2 $ chmod +x /tmp/t* $ /tmp/t2 zsh: exec format error: /tmp/t2 Similar problem with binfmt_misc. This patch introduces field 'recursion_depth' into struct linux_binprm to track recursion level in binfmt_misc and binfmt_script. If recursion level more then BINPRM_MAX_RECURSION it generates -ENOEXEC. [akpm@linux-foundation.org: make linux_binprm.recursion_depth a uint] Signed-off-by:

When reporting some complex trailing statements we report only the starting line of the error, that tends to imply the shown line is in error and confuse the reader. As we do know where the actual error is report that line too with an appropriate gap marker where applicable. #ERROR: trailing statements should be on next line #1: FILE: Z202.c:1: + for (pbh = page_buffers(bh->b_page); pbh != bh; + pbh = pbh->b_this_page, key++); #ERROR: trailing statements should be on next line #4: FILE: Z202.c:4: + for (pbh = page_buffers(bh->b_page); [...] + pbh = pbh->b_this_page, key++); Signed-off-by: -
