Revert "Bias the placement of kernel pages at lower PFNs"

This reverts commit 5adc5be7cd1bcef6bb64f5255d2a33f20a3cf5be.

Alexey Dobriyan reports that it causes huge slowdowns under some loads,
in his case a "mkfs.ext2" on a 30G partition.  With the placement bias,
the mkfs took over four minutes, with it reverted it's back to about ten
seconds for Alexey.
