2010-05-27vhost: fix to check the return value of copy_to/from_user() correctlyTakuya Yoshikawa
copy_to/from_user() returns the number of bytes that could not be copied. So we need to check if it is not zero, and in that case, we should return the error number -EFAULT rather than directly return the return value from copy_to/from_user().

2010-05-27arch/x86/kernel: Add missing spin_unlockJulia Lawall
Add a spin_unlock missing on the error path. The locks and unlocks are balanced in other functions, so it seems that the same should be the case here. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ * spin_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * spin_unlock(E1,...); // </smpl> Cc: stable@kernel.org Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2010-05-27ARM: 6146/1: sa1111: Prevent deadlock in resume pathMarek Vašut
This patch reorganises the sa1111_resume() function in a manner the spinlock happens after calling the sa1111_wake(). This fixes two bugs: 1) This function called sa1111_wake() which tried to claim the same spinlock the sa1111_resume() already claimed. This would result in certain deadlock. Original idea for this part: Russell King <rmk+kernel@arm.linux.org.uk> 2) The function didn't unlock the spinlock in case the chip didn't report correct ID.

2010-05-27ARM: 6145/1: ux500 MTU clockrate correctionLinus Walleij
This adjusts the clockrate for the MTU timer. On the different UX500 variants this rate is different. The platform can also have been set up at hardware initialization, bootloader or early init for different clock speeds. To have the clock framework available early so the timers can use them, the clock initialization for Nomadik and ux500 is moved to IRQ init time. A custom per-clock callback is added to handle special cases like this. This solves a user-visible bug: without this patch the current UX500 platforms will not be synchronized to wall-clock time and the platform will drift in time.

2010-05-27ARM: 6144/1: TCM memory bug freeing bugLinus Walleij
This fixes a bug in mm/init.c when freeing the TCM compile memory, this was being referred to as a char * which is incorrect: this will dereference the pointer and feed in the value at the location instead of the address to it. Change it to a plain char and use &(char) to reference it.

2010-05-27net: fix lock_sock_bh/unlock_sock_bhEric Dumazet
This new sock lock primitive was introduced to speedup some user context socket manipulation. But it is unsafe to protect two threads, one using regular lock_sock/release_sock, one using lock_sock_bh/unlock_sock_bh This patch changes lock_sock_bh to be careful against 'owned' state. If owned is found to be set, we must take the slow path. lock_sock_bh() now returns a boolean to say if the slow path was taken, and this boolean is used at unlock_sock_bh time to call the appropriate unlock function. After this change, BH are either disabled or enabled during the lock_sock_bh/unlock_sock_bh protected section. This might be misleading, so we rename these functions to lock_sock_fast()/unlock_sock_fast().

2010-05-26Input: ads7846 - return error on regulator_get() failureKevin Hilman
In probe(), if regulator_get() failed, an error code was not being returned causing the driver to be successfully bound, even though probe failed. This in turn caused the suspend, resume and remove methods to be registered and accessed via the SPI core. Since these functions all access private driver data using pointers that had been freed during the failed probe, this would lead to unpredictable behavior. This patch ensures that probe() returns an error code in this failure case so the driver is not bound. Found using lockdep and noticing the lock used in the suspend/resum path pointed to a bogus lock due to the freed memory.
