Revision 835d1c3a98799914db8aee0973018af21128cd1e authored by Marc Zyngier on 30 July 2020, 09:53:05 UTC, committed by Will Deacon on 30 July 2020, 15:55:32 UTC
asm/pointer_auth.h is not needed anymore in asm/smp.h, as 62a679cb2825 ("arm64: simplify ptrauth initialization") removed the keys from the secondary_data structure. This also cures a compilation issue introduced by f227e3ec3b5c ("random32: update the net random state on interrupt and activity"). Fixes: 62a679cb2825 ("arm64: simplify ptrauth initialization") Fixes: f227e3ec3b5c ("random32: update the net random state on interrupt and activity") Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Will Deacon <will@kernel.org>
