From f186a84d8abecc7dfbd5bbd0a8ad0358078e4767 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Fri, 28 Aug 2020 19:11:48 +0100 Subject: [PATCH] arm64/fpsimd: Update documentation of do_sve_acc fpsimd_restore_current_state() enables and disables the SVE access trap based on TIF_SVE, not task_fpsimd_load(). Update the documentation of do_sve_acc to reflect this behavior.
