[PATCH] arm64: cpu_errata: include required headers

[PATCH] arm64: cpu_errata: include required headers

[Arnd Bergmann]

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);

This showed up only recently, but I have not bisected what caused it.

I haven't hit it yet, not sure why. I'm queuing the patch anyway.
Thanks.
