futex: Sanitize futex ops argument types

2011-08-03T22:40:50+00:00

Change futex_atomic_op_inuser and futex_atomic_cmpxchg_inatomic
prototypes to use u32 types for the futex as this is the data type the
futex core code uses all over the place.

futex: Sanitize cmpxchg_futex_value_locked API

2011-08-03T22:40:50+00:00

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.

microblaze: Fix pte_update function

2011-02-07T18:12:30+00:00

Do not disable irq in asm but use irq macros.
Systems with MSR=0 couldn't use pte_update function
because msrclr was hardcoded.

microblaze: Fix asm/pgtable.h

2011-01-16T13:29:41+00:00

Function ptep_test_and_clear_young have had wrong the first argument.
It is also necessary to add __HAVE macros for ptep_test_and_clear_young and
ptep_get_and_clear functions.

A definition like:

called with PVR_IS_FULL(foo) will be preprocessed to:

(foo.foo[0] & PVR0_PVR_FULL_MASK)
     ^^^
So to fix this and ensure the preprocessor compiles calls correctly:

of/net: Move of_get_mac_address() to a common source file.

2010-11-01T05:08:14+00:00

There are two identical implementations of of_get_mac_address(), one
each in arch/powerpc/kernel/prom_parse.c and
arch/microblaze/kernel/prom_parse.c.  Move this function to a new
common file of_net.{c,h} and adjust all the callers to include the new

mm: remove pte_*map_nested()

Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.
