From: Vincenzo Frascino <vincenzo.frascino@arm.com> Hardware tag-based KASAN relies on Memory Tagging Extension (MTE) feature and requires it to be enabled. MTE supports This patch adds a new mte_init_tags() helper, that enables MTE in Synchronous mode in EL1 and is intended to be called from KASAN runtime during initialization.There's no mte_init_tags() in this function.During the rework, I realized that the description of mte_init_tags() in this patch refers to mte_enable_kernel(). In fact the only thing that mte_init_tags() does is to configure the GCR_EL1 register, hence my preference would be to keep all the code that deals with such a register in one patch.Fine by me as long as the commit text is consistent with the diff.
Done already, it will be in the next series. Thank you for the quick turnaround. -- Regards, Vincenzo _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
