That'll be because swap emulation isn't in v2.6.37-rc1.  It's queued
for 2.6.38's merge window.

It's also queued for 2.6.38, but there is an issue with the latest gcc
stuffing a .armv7 directive (or whatever) at the beginning of its
output, thereby overriding the -Wa,-march=armv7-a on the command line.
I think someone's looking at fixing GCC.

This stuff _is_ in linux-next, and has been in linux-next for ages.
