Andrew,

I would like to update the changelogs for patches 2 and 3.
There are no changes to the code. Sorry for the inconvenience.

The original changelog is not accurate: it's solely the ra->mmap_miss updates
that caused cache line bouncing on tmpfs. ra->prev_pos won't be updated at all
on tmpfs.

Thanks,
Fengguang
