From c60f99445aed684b5a8d84dcb84f5a06c1f70430 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Sun, 12 Jul 2015 18:11:20 -0500 Subject: MIPS: MT: Remove "weak" from vpe_run() declaration Weak header file declarations are error-prone because they make every definition weak, and the linker chooses one based on link order (see 10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node decl")). That's not a problem for vpe_run() because Kconfig ensures there's never more than one definition: - vpe_run() is defined in arch/mips/kernel/vpe-mt.c if CONFIG_MIPS_VPE_LOADER_MT=y - vpe_run() is defined in arch/mips/mti-malta/malta-amon.c if CONFIG_MIPS_CMP=y - CONFIG_MIPS_VPE_LOADER_MT cannot be set if CONFIG_MIPS_CMP=y But it's simpler to verify correctness if we remove "weak" from the picture and test the config symbols directly. Remove "weak" from the vpe_run() declaration and use #if to test whether a definition should be present.
