Hmm...that must be a pretty ancient toolchain. In any case, the patch
below should fix it. The commit being reverted is not in mainline, so
I'll probably just drop both of them next time I rebase.

FWIW, a more recent toolchain is available here:

Subject: [PATCH] Revert "avr32: Use better asm constraint in prefetch()"

This reverts commit e153fa1406b68460e0a8e498a2b83d50584cc40a.

This commit caused build breakage with some old 4.0.2-based gcc.
