2011-03-23bitops: introduce CONFIG_GENERIC_FIND_BIT_LEAkinobu Mita
This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic implementation of find_*_bit_le() in lib/find_next_bit.c or not. For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which enable CONFIG_GENERIC_FIND_NEXT_BIT. But m68knommu wants to define own faster find_next_zero_bit_le() and continues using generic find_next_{,zero_}bit().

Reset vector can be setup by bootloader and kernel doens't need to touch it. If you require to setup reset vector, please use CONFIG_MANUAL_RESET_VECTOR throught menuconfig. It is not possible to setup address 0x0 as reset address because make no sense to set it up at all.

2011-03-15microblaze: Fix microblaze init vectorsMichal Simek
Microblaze vector table stores several vectors (reset, user exception, interrupt, debug exception and hardware exception). All these functions can be below address 0x10000. If they are, wrong vector table is genarated because jump is not setup from two instructions (imm upper 16bit and brai lower 16bit). Adding specific offset prevent problem if address is below 0x10000. For this case only brai instruction is used. Signed-off-by: Michal Simek <monstr@monstr.eu>

2011-03-11futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse
The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

2011-03-09microblaze: Fix /dev/zero corruption from __clear_user()Steven J. Magnani
A userland read of more than PAGE_SIZE bytes from /dev/zero results in (a) not all of the bytes returned being zero, and (b) memory corruption due to zeroing of bytes beyond the user buffer. This is caused by improper constraints on the assembly __clear_user function. The constrints don't indicate to the compiler that the pointer argument is modified. Since the function is inline, this results in double-incrementing of the pointer when __clear_user() is invoked through a multi-page read() of /dev/zero. Signed-off-by: Steven J.
