- the LEAP_YEAR macro is buggy - it references its arg multiple times. Fix this by turning it into a C function. - give it a more approriate name - Move it to rtc.h so that other .c files can use it, instead of copying it. Cc: dann frazier <dannf@hp.com> Acked-by:

A deadlock can occur when user space uses a signal (autofs version 4 uses SIGCHLD for this) to effect expire completion. The order of events is: Expire process completes, but before being able to send SIGCHLD to it's parent ... Another process walks onto a different mount point and drops the directory inode semaphore prior to sending the request to the daemon as it must ... A third process does an lstat on on the expired mount point causing it to wait on expire completion (unfortunately) holding the directory semaphore. The mount request then arrives at the daemon which does an lstat and, deadlock. For some time I was concerned about releasing the directory semaphore around the expire wait in autofs4_lookup as well as for the mount call back. I finally realized that the last round of changes in this function made the expiring dentry and the lookup dentry separate and distinct so the check and possible wait can be done anywhere prior to the mount call back. This patch moves the check to just before the mount call back and inside the directory inode mutex release. Signed-off-by:

A significant portion of the autofs_dev_ioctl_expire() and autofs4_expire_multi() functions is duplicated code. This patch cleans that up. Signed-off-by:

Implement full support for OF SPI bindings. Now the driver can manage its own chip selects without any help from the board files and/or fsl_soc constructors. The "legacy" code is well isolated and could be removed as time goes by. Signed-off-by:

The main purpose of this patch is to pass 'struct spi_device' to the chip select handling routines. This is needed so that we could implement full-fledged OpenFirmware support for this driver. While at it, also: - Replace two {de,activate}_cs routines by single cs_contol(). - Don't duplicate platform data callbacks in mpc83xx_spi struct. Signed-off-by: -

I have a laptop HP Compaq 8710W, I compiled into my kernel the LIS3LV02DL and HP_ACCEL module drivers. While loading it cannot recognize the laptop model, so i am sending the necessary information to update the database of axis orientations. >When the laptop is horizontal the position reported is about 0 for X and Y >and a positive value for Z Yes, it is about 0,0,1000, the actual reading says: (-17,-26,1018); > If the left side is elevated, X increases (becomes positive) Yes, X goes toward to positive 1000. >If the front side (where the touchpad is) is elevated, Y decreases (becomes negative) No, Y goes toward to positive 1000. >If the laptop is put upside-down, Z becomes negative Yes, the laptop on a table Z gives 1000, and if upsidedown the Z reads -1000. So in few words the Y axis is inverted. Cc: Eric Piel <eric.piel@tremplin-utc.net> Signed-off-by:

Add Linux support for the Linear Technology LTC4215 Hot Swap controller I2C monitoring interface. I have tested the driver with my board, and it appears to work fine. With the power supplies disabled, it reads 11.93V input, 1.93V output, no current and no power. With the supplies enabled, it reads 11.93V input, 11.98V output, no current, no power. I'm not drawing any current at the moment, so this is reasonable. The value in the sense register never reads anything except 0, so I expect to get zero from the current and power calculations. I didn't attempt to support changing any of the chip's settings or enabling the FET. I'm not sure even how to do that and still fit within the hwmon framework. :) Signed-off-by:

Use the events hint now sent by some devices, to avoid unnecessary wakeups for events that are of no interest for the caller.
