Linus Torvalds 44048d700b Revert "Bias the placement of kernel pages at lower PFNs" ... This reverts commit 5adc5be7cd. 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.
