Hi Suzuki,

This series adds CPU erratum work arounds related to the self-hosted
tracing. The list of affected errata handled in this series are :

 * TRBE may overwrite trace in FILL mode
   - Arm Neoverse-N2	#2139208
   - Cortex-A710	#211985

 * A TSB instruction may not flush the trace completely when executed
   in trace prohibited region.

   - Arm Neoverse-N2	#2067961
   - Cortex-A710	#2054223

 * TRBE may write to out-of-range address
   - Arm Neoverse-N2	#2253138
   - Cortex-A710	#2224489

The series applies on the self-hosted/trbe fixes posted here [0].
A tree containing both the series is available here [1]
Any chance you could put the arch/arm64/ bits at the start of the series,
please? That way, I can queue them on their own branch which can be shared
with the coresight tree.

Thanks,

Will
