10 | * Add support for 64-bit put_user/get_user | ||

16 | * - Provide implementation for everything else but get_user and put_user; | ||
17 | * copying inline to/from user for constant length 0..16, 20, 24, and | ||
18 | * clearing for 0..4, 8, 12, 16, 20, 24, strncpy_from_user and strnlen_user | ||
19 | * always inline. | ||
20 | * - Constraints for destination addr in get_user cannot be memory, only reg. | ||
21 | * - Correct labels for PC at expected fault points. | ||
22 | * - Nits with assembly code. | ||
23 | * - Don't use statement expressions without value; use "do {} while (0)". | ||
24 | * - Return correct values from __generic_... functions. | ||
