Mark get_current() and current_thread_info() functions as always_inline to fix the following modpost warning: WARNING: modpost: vmlinux: section mismatch in reference: get_current+0xc (section: .text.unlikely) -> initcall_level_names (section: .init.data) The warning happens when these functions are called from an __init function and they don't get inlined (remain in the .text section) while the value they return points into .init.data section. Assuming get_current() always returns a valid address, this situation can happen only during init stage and accessing .init.data from .text section during that stage should pose no issues.
