| |
Commit 75182b1632 ("x86/asm/entry: Switch all C consumers of kernel_stack to this_cpu_sp0()") changed current_thread_info to use this_cpu_sp0, and indirectly made it rely on init_tss which was exported with EXPORT_PER_CPU_SYMBOL_GPL. As a result some macros and inline functions such as set/get_fs, test_thread_flag and variants have been made unusable for external modules.
Make cpu_tss exported with EXPORT_PER_CPU_SYMBOL so that these functions are accessible again, as they were previously.
