as I wrote in the other email, e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e removes cleanup_highmap_brk_end but this function was not only dealing with mappings but it was also setting mmu_cr4_features, therefore the setting of mmu_cr4_features was lost.
I think the real bug is that mmu_cr4_features ended up in cleanup_highmap_brk_end by mistake.
