[PATCH 0/3] arm64/ptrace: Fixes for more SME only streaming SVE cases

From: Mark Brown
Date: Thu Aug 03 2023 - 14:44:23 EST


When we added support for streaming mode SVE there were several missed
cases around ptrace, address them. Some could be seen on systems which
do physically have SVE, others would only impact SME only systems. The
Fixes: tag is a bit conservative for the SME only cases but it seems
like the safest and clearest choice.
