Is this a manual (git grep) based work or have you used Coccinele for
the patch generation?

My potentially incomplete check
$ git grep ">[[:space:]]*vm_flags[[:space:]]*[&|^]="

shows that nothing should be left after this. There is still quite a lot
of direct checks of the flags (more than 600). Maybe it would be good to
make flags accessible only via accessors which would also prevent any
future direct setting of those flags in uncontrolled way as well.

Anyway
