I've fixed this and sent a patch (included below) to Will for his delay branch,

Subject: [PATCH] ARM: delay: export read_current_timer to fix get_cycles
On ARM, get_cycles() is implemented in terms of read_current_timer(), but
the latter is not exported to modules, resulting in failure to link:
ERROR: "read_current_timer" [fs/ext4/ext4.ko] undefined!
This patch exports the symbol as required.
