[PATCH] RISC-V: Define get_cycles64() regardless of M-mode

From: Palmer Dabbelt
Date: Wed Nov 25 2020 - 14:58:32 EST


From: Palmer Dabbelt <palmerdabbelt@xxxxxxxxxx>

The timer driver uses get_cycles64() unconditionally to obtain the current
time. A recent refactoring lost the common definition for some configs, which
is now the only one we need.

Fixes: d5be89a8d118 ("RISC-V: Resurrect the MMIO timer implementation for M-mode systems")
