A72 access to cache syndrome registers (arm64)

Hello -
Is there any current support for reading "CPU Memory Error Syndrome"
and L2 Memory Error Syndrome" registers from userspace? I am
monitoring for particular cache related events.  I'm trying to avoid
writing a kernel module but it looks like  that may be my only option
as I am not seeing support for access to these registers. Would a perf
driver be more appropriate? Any advice/input  appreciated.

My Linux kernel is 4.14 but I could adjust is support is available elsewhere.

Thanks,
Joe
