| * | arm64: use generic strnlen_user and strncpy_from_user functions | Will Deacon | 2013-12-19 | 1 | -47/+0 |
| | | | | | | | | | | | | | | This patch implements the word-at-a-time interface for arm64 using the same algorithm as ARM. We use the fls64 macro, which expands to a clz instruction via a compiler builtin. Big-endian configurations make use of the implementation from asm-generic. With this implemented, we can replace our byte-at-a-time strnlen_user and strncpy_from_user functions with the optimised generic versions.

| * | arm64: User access library functions | Catalin Marinas | 2012-09-17 | 1 | -0/+47 |
| This patch add support for various user access functions. These functions use the standard LDR/STR instructions and not the LDRT/STRT variants in order to allow kernel addresses (after set_fs(KERNEL_DS)).
