Switch to CONFIG_TRANSPARENT_HUGEPAGE_MADVISE instead of always on
The benefit of THP has been somewhat questionable overall for a while, and it's been known to cause performance issues with some workloads. Upstream also considers it to be overly complicated and really not worth it on machines with memory in the amounts found on typical desktops/SMB servers. Switch to using it via madvise, which most applications that care about it should likely already be doing.
