Subject[PATCH v2 0/8] vdso: Complete the conversion to 32bit syscalls
This patch series is a follow up to "lib/vdso, x86/vdso: Fix fallout
from generic VDSO conversion" [1].

The main purpose is to complete the 32bit vDSOs conversion to use the
legacy 32bit syscalls as a fallback. With the conversion of all the
architectures present in -next complete, this patch series removes as
well the conditional choice in between 32 and 64 bit for 32bit vDSOs.

This series has been rebased on linux-next/master.
