Analyze and fix the following issue in the Linux kernel code: [module] Don't let gcc inline load_module()
Problem Details: 'load_module()' is a complex function that contains all the ELF section logic, and inlining it is utterly insane. But gcc will do it, simply because there is only one call-site. As a result, all the stack space that is allocated for all the work to load the module will still be active when we actuall...

Problem Details: CONFIG_SFC=m uses topology_core_siblings() which, for ia64, expects cpu_core_map to be exported. It is not. This patch exports the needed symbol.
