Subject: [PATCH] KVM: arm64: fix __kvm_host_psci_cpu_entry() prototype
From: Arnd Bergmann <arnd@...db.de>
The kvm_host_psci_cpu_entry() function was renamed in order to add a wrapper around
it, but the prototype did not change, so now the missing-prototype warning came
back in W=1 builds:
arch/arm64/kvm/hyp/nvhe/psci-relay.c:203:28: error: no previous prototype for function '__kvm_host_psci_cpu_entry' [-Werror,-Wmissing-prototypes]
asmlinkage void __noreturn __kvm_host_psci_cpu_entry(bool is_cpu_on)
Fixes: dcf89d1111995 ("KVM: arm64: Add missing BTI instructions")
