sh3 ports define __SWAP_BROKEN in sys/arch/sh3/include/types.h, so in
sys/uvm/uvm_pdaemon.c uvm_swapout_threads() is never called (thanks to
mrg for pointign this out).

__SWAP_BROKEN is also defined for mips ports.

I'm not familiar with that part of the kernel, so I don't know why
it's marked as broken.  Since for sh3 __SWAP_BROKEN was defined in the
same commit, in which the __HAVE_AST_PERPROC was added, may be it
needs the u-area to deliver an ast (but that's just a wild guess).

Any hints from folks who know how this works?

SY, Uwe
