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. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
