6.12-stable review patch. If anyone has any objections, please let me know.

From: Konrad Dybcio konrad.dybcio@oss.qualcomm.com
commit 35d8bc131de0f0f280f0db42499512d79f05f456 upstream.
The Last Level Cache is split into many slices, each one of which can be toggled on or off.
Only certain slices are recommended to be turned on unconditionally, in order to reach optimal performance/latency/power levels.
Enable WRCACHE on X1 at boot, in accordance with internal recommendations.
No significant performance difference is expected.
