linux.git/Documentation/features/core/thread-info-in-task, branch v5.16 Linux kernel source tree parisc: Move thread_info into task struct 2021-11-01T06:35:59+00:00 Helge Deller deller@gmx.de 2021-10-15T08:41:03+00:00 2214c0e77259b420402e279e9ab4277ef320d371 This implements the CONFIG_THREAD_INFO_IN_TASK option. With this change: - before thread_info was part of the stack and located at the beginning of the stack - now the thread_info struct is moved and located inside the task_struct structure - the stack is allocated and handled like the major other platforms - drop the cpu field of thread_info and use instead the one in task_struct Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Sven Schnelle <svens@stackframe.org>
