ehm "cleaner then"
If you've suggestions for a better name than PageTransCompoundMap I
can respin a new patch though, I considered "CanMap" but I opted for
the short version.
Also I'm not really sure moving transparent_hugepage_adjust will make
much sense. I mentioned it because Andres in another thread said it
was suggested but the real common code knowledge is about
PageTransCompoundMap only, all sort of !mmu_gfn_lpage_is_disallowed
for dirty logging at 4k shadow granularity is KVM internal.
