This fix can still be applied to older kernels, but seems to me that now might be an appropriate time to consider removing the ETMv3 driver from the mainline kernel?
Yeah, if anyone is using it it would be on an old kernel surely?
We can confirm this in another way: if I don't miss anything, over the past several years (since 2017), we have not received any questions or bug reports based on hands-on practice regarding ETMv3 on the Coresight or perf mailing lists.
