hexagon: fix strncpy_from_user() error return

2016-09-29T09:14:34+00:00

commit f35c1e0671728d1c9abc405d05ef548b5fcb2fc4 upstream.

It's -EFAULT, not -1 (and contrary to the comment in there,
__strnlen_user() can return 0 - on faults).

arc,hexagon: Delete asm/barrier.h

2015-10-28T15:37:40+00:00

commit 2ab08ee9f0a4eba27c7c4ce0b6d5118e8a18554b upstream.

Both already use asm-generic/barrier.h as per their
include/asm/Kbuild. Remove the stale files.

into the atomic implementation.

arch: Clean up asm/barrier.h implementations using asm-generic/barrier.h

2015-10-28T15:37:39+00:00

commit 93ea02bb84354370e51de803a9405f171f3edf88 upstream.

We're going to be adding a few new barrier primitives, and in order to
avoid endless duplication make more agressive use of
asm-generic/barrier.h.

Change the asm-generic/barrier.h such that it allows partial barrier
definitions and fills out the rest with defaults.

There are a few architectures (m32r, m68k) that could probably
do away with their barrier.h file entirely but are kept for now due to
their unconventional nop() implementation.
