Subject: drivers: firmware: psci: Use __pa_symbol for kernel symbol
X-Git-Tag: kvm-4.11-2~18^2~52^2

drivers: firmware: psci: Use __pa_symbol for kernel symbol

__pa_symbol is technically the macro that should be used for kernel
symbols. Switch to this as a pre-requisite for DEBUG_VIRTUAL which
will do bounds checking.
