| H A D | switch_to.h | 18ed1c01 Sat Sep 18 03:44:38 CDT 2021 Ard Biesheuvel <ardb@kernel.org> ARM: smp: Enable THREAD_INFO_IN_TASK
Now that we no longer rely on thread_info living at the base of the task
stack to be able to access the 'current' pointer, we can wire up the
generic support for moving thread_info into the task struct itself.
Note that this requires us to update the cpu field in thread_info
explicitly, now that the core code no longer does so. Ideally, we would
switch the percpu code to access the cpu field in task_struct instead,
but this unleashes #include circular dependency hell.
