I had an older patch that I revived to have this defined through Kconfig rather than through including asm/page.h, which is not allowed in vdso code. I rebased and tested on top of the tip/timers/core branch that introduced the regression. If these patches get added, the compat VDSOs all build again, but the changes are a bit invasive.
