* move count_zeroes.h out of asm-genericChristoph Hellwig2017-04-111-57/+0
| | | | | | | | This header contains a few helpers currenly only used by the mpi implementation, and not default implementation of architecture code. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* 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: make get_user() clear the destination on errorsAl Viro2017-04-111-3/+7
| | | | | | | | | commit 9ad18b75c2f6e4a78ce204e79f37781f8815c0fa upstream. both for access_ok() failures and for faults halfway through Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 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>
* asm-generic: processor.h: remove redundant macrosSumit Singh2016-09-101-7/+1
| | | | | | | | | | | | | | | | | | Removing cpu_relaxed_read and cpu_relaxed_read_long macros from processor.h, as these macros are defined in asm-generic/relaxed.h.
