| * | lib: Fix generic strnlen_user for 32-bit big-endian machines | Paul Mackerras | 2012-05-27 | 1 | -1/+1 |
| | | | | | | | | | | | | The aligned_byte_mask() definition is wrong for 32-bit big-endian machines: the "7-(n)" part of the definition assumes a long is 8 bytes. This fixes it by using BITS_PER_LONG - 8 instead of 8*7. Tested on 32-bit and 64-bit PowerPC. Signed-off-by: Paul Mackerras <paulus@samba.org> Acked-by: David S.

| * | lib: add generic strnlen_user() function | Linus Torvalds | 2012-05-26 | 1 | -0/+138 |
| This adds a new generic optimized strnlen_user() function that uses the <asm/word-at-a-time.h> infrastructure to portably do efficient string handling. In many ways, strnlen is much simpler than strncpy, and in particular we can always pre-align the words we load from memory. That means that all the worries about alignment etc are a non-issue, so this one can easily be used on any architecture. You obviously do have to do the appropriate word-at-a-time.h macros.
