+Subject: ARM: 8957/1: VDSO: Match ARMv8 timer in cntvct_functional()
+
+From: Florian Fainelli <f.fainelli@gmail.com>
+
+commit 45939ce292b4b11159719faaf60aba7d58d5fe33 upstream.
+
+It is possible for a system with an ARMv8 timer to run a 32-bit kernel.
+When this happens we will unconditionally have the vDSO code remove the
+__vdso_gettimeofday and __vdso_clock_gettime symbols because
+cntvct_functional() returns false since it does not match that
+compatibility string.
+
+Fixes: ecf99a439105 ("ARM: 8331/1: VDSO initialization, mapping, and synchronization")
