So on the basis that this patch adds back a full cache clean+invalidate that was inadvertently removed by my previous patch, I think we should apply this patch. GIven that this change can be traced back to commit 401b368caaecdce1cf8f05bab448172752230cb0, we should probably include Fixes: 401b368caaec ("ARM: decompressor: switch to by-VA cache maintenance for v7 cores") Are you on board with that?Yes, I think that's definitely the commit which introduced this bug.BTW, there's no need to submit your patch to the patch system, I obviously already have it in my tree. I'll move it over to the usual "fixes" branch in due course. Thanks.
Oops, I already did so yesterday. I did expand a bit on the commit log, and added the fixes header, but either version is fine with me. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
