Not tested on x86 or arm64, would appreciate a quick test there so I can ask Andrew to put it in -mm. Other option is I can disable huge vmallocs for them for the time being. Since v2: - Rebased on vmalloc cleanups, split series into simpler pieces. - Fixed several compile errors and warnings - Keep the page array and accounting in small page units because struct vm_struct is an interface (this should fix x86 vmap stack debug assert).
