And later on we run out of vmalloc space a lot getting warnings like
this:

[ 5796.986579] vmap allocation for size 4194304 failed: use
vmalloc=<size> to increase size.
[ 5797.008728] xfs_buf_get_noaddr: failed to map pages


This didn't happen before.  Maybe it's a result of some of the more
lazy TLB flushing?
