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.
Fixes: 22d407b164ff ("lib: add allocation tagging support for memory allocation profiling")
