* locking/mcs: Allow architecture specific asm files to be used for contended caseTim Chen2017-05-031-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows each architecture to add its specific assembly optimized arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for MCS lock and unlock functions.

* asm-generic: make copy_from_user() zero the destination properlyAl Viro2017-04-111-4/+6
| | | | | | | | | | | | | | | commit 2545e5da080b4839dd859e3b09343a884f6ab0e3 upstream. ... in all cases, including the failing access_ok() Note that some architectures using asm-generic/uaccess.h have __copy_from_user() not zeroing the tail on failure halfway through. This variant works either way. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> [wt: s/might_fault/might_sleep] Signed-off-by: Willy Tarreau <w@1wt.eu>

* asm-generic: rwsem: ensure sem->cnt is only accessed via atomic_long_*Will Deacon2016-09-131-1/+1
| | | | | | | | | The asm-generic rwsem implementation directly acceses sem->cnt when performing a __down_read_trylock operation. Whilst this is probably safe on all architectures, we should stick to the atomic_long_* API and use atomic_long_read instead. Signed-off-by: Will Deacon <will.deacon@arm.com>
