From: Anton Blanchard Date: Thu, 12 Jun 2014 08:16:53 +0000 (+1000) Subject: KVM: PPC: Assembly functions exported to modules need _GLOBAL_TOC() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ad7d4584a225e3c1ac634dc803421fe842491ecf;p=linux-beck.git KVM: PPC: Assembly functions exported to modules need _GLOBAL_TOC() Both kvmppc_hv_entry_trampoline and kvmppc_entry_trampoline are assembly functions that are exported to modules and also require a valid r2. As such we need to use _GLOBAL_TOC so we provide a global entry point that establishes the TOC (r2).
