kernel: exit: cleanup release_thread()

2022-09-12T04:55:07+00:00

Only x86 has own release_thread(), introduce a new weak release_thread() function to clean empty definitions in other ARCHs.

sched: Add wrapper for get_wchan() to keep task blocked

2021-10-15T09:25:14+00:00

Having a stable wchan means the process must be blocked and for it to stay that way while performing stack unwinding.

Pull microblaze updates from Michal Simek: "The biggest change is to remove support for noMMU configuration. FPGAs are bigger so people use Microblaze with MMU for a lot of years and there is likely no user of this code anymore. No one is updating libraries for this configuration either. - Remove noMMU support - Add support for TIF_NOTIFY_SIGNAL - Small header fix" * tag 'microblaze-v5.11' of git://git.monstr.eu/linux-2.6-microblaze: microblaze: Remove noMMU code microblaze: add support for TIF_NOTIFY_SIGNAL microblaze: Replace by

microblaze: Remove noMMU code

2020-11-26T15:39:35+00:00

This configuration is obsolete and likely none is really using it. That's why remove it to simplify code. Note about CONFIG_MMU in hw_exception_handler.S is left intentionally for better comment understanding.

treewide: remove current_text_addr

2018-10-31T15:54:12+00:00

Prefer _THIS_IP_ defined in linux/kernel.h. Most definitions of current_text_addr were the same as _THIS_IP_, but a few archs had inline assembly instead. This patch removes the final call site of current_text_addr, making all of the definitions dead code.

arch: remove unused macro/function thread_saved_pc()

2017-06-28T23:13:57+00:00

The only user of thread_saved_pc() in non-arch-specific code was removed in commit 8243d5597793 ("sched/core: Remove pointless printout in sched_show_task()"). Remove the implementations as well. Some architectures use thread_saved_pc() in their arch-specific code. Leave their thread_saved_pc() intact.

locking/core: Provide common cpu_relax_yield() definition

2016-11-17T07:17:36+00:00

No need to duplicate the same define everywhere. Since the only user is stop-machine and the only provider is s390, we can use a default implementation of cpu_relax_yield() in sched.h.
