Reiji Watanabe f0cb43a2c6 arm64: clear_page() shouldn't use DC ZVA when DCZID_EL0.DZP == 1 ... [ Upstream commit f0616abd4e67143b45b04b565839148458857347 ] Currently, clear_page() uses DC ZVA instruction unconditionally. But it should make sure that DCZID_EL0.DZP, which indicates whether or not use of DC ZVA instruction is prohibited, is zero when using the instruction. Use STNP instead when DCZID_EL0.DZP == 1.
