From 9ce751a6f5d6683b0fabd3cfc62da7e9f30bc57f Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Mon, 16 Apr 2018 10:15:12 +0200 Subject: psci: arm: remove armv7 function psci_save_target_pc This function is no more used, and replaced by psci_save which save also context id as requested by PSCI requirements. Even if the context id is not used by Linux, it should be saved and restored in r0 when the CPU_ON is performed.
