PLD prefetches on TLB misses.
Well, nowadays modern ARM processors got automatic hardware
prefetchers, which greatly reduce or eliminate the need for
doing prefetch in software. Here is a test patch for pixman,

The following 32-bit ARM code
mov TMP1, X, asr #16
add TMP1, TOP, TMP1, asl #2
needs to be converted into
asr TMP1, X, #16
add TMP1, TOP, TMP1, lsl #2
in order to be accepted by both 32-bit and 64-bit ARM assemblers.
The conversion has been done using the
