* mm/uaccess, mm/fault: Clarify that uaccess may only sleep if pagefaults are ↵David Hildenbrand2015-05-191-10/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | enabled In general, non-atomic variants of user access functions must not sleep if pagefaults are disabled. Let's update all relevant comments in uaccess code. This also reflects the might_sleep() checks in might_fault().

* m32r: macro whitespace fixesMichael S. Tsirkin2015-01-131-42/+42
| | | | | | | | | | While working on arch/m32r/include/asm/uaccess.h, I noticed that some macros within this header are made harder to read because they violate a coding style rule: space is missing after comma. Fix it up. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* m32r/uaccess: fix sparse errorsMichael S. Tsirkin2015-01-131-2/+2
| | | | | | | | | | virtio wants to read bitwise types from userspace using get_user. At the moment this triggers sparse errors, since the value is passed through an integer. Fix that up using __force. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* m32r: uaccess s/might_sleep/might_fault/Michael S. Tsirkin2013-05-281-6/+6
| | | | | | | | | | | | | The only reason uaccess routines might sleep is if they fault. Make this explicit. Signed-off-by: Michael S.
