Merge tag 'remove-weak-declarations' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull weak function declaration removal from Bjorn Helgaas: "The "weak" attribute is commonly used for the default version of a function, where an architecture can override it by providing a strong version. Some header file declarations included the "weak" attribute. That's error-prone because it causes every implementation to be weak, with no strong version at all, and the linker chooses one based on link order. What we want is the "weak" attribute only on the *definition* of the default implementation. These changes remove "weak" from the declarations, leaving it on the default definitions" * tag 'remove-weak-declarations' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: uprobes: Remove "weak" from function declarations memory-hotplug: Remove "weak" from memory_block_size_bytes() declaration kgdb: Remove "weak" from kgdb_arch_pc() declaration ARC: kgdb: generic kgdb_arch_pc() suffices vmcore: Remove "weak" from function declarations clocksource: Remove "weak" from clocksource_default_clock() declaration x86, intel-mid: Remove "weak" from function declarations audit: Remove "weak" from audit_classify_compat_syscall() declaration
