[PATCH 4.9 101/125] arm64: cpu_errata: include required headers

From: Greg Kroah-Hartman
Date: Wed Apr 22 2020 - 06:54:16 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

commit 94a5d8790e79ab78f499d2d9f1ff2cab63849d9f upstream.

Without including psci.h and arm-smccc.h, we now get a build failure in
some configurations:

arch/arm64/kernel/cpu_errata.c: In function 'arm64_update_smccc_conduit':
arch/arm64/kernel/cpu_errata.c:278:10: error: 'psci_ops' undeclared (first use in this function); did you mean 'sysfs_ops'?

arch/arm64/kernel/cpu_errata.c: In function 'arm64_set_ssbd_mitigation':
arch/arm64/kernel/cpu_errata.c:311:3: error: implicit declaration of function 'arm_smccc_1_1_hvc' [-Werror=implicit-function-declaration]
arm_smccc_1_1_hvc(ARM_SMCCC_ARCH_WORKAROUND_2, state, NULL);
