parisc build failures in mainline kernel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

the mainline kernel fails to build almost all 'parisc' images.

The first build error is

In file included from <command-line>:
include/linux/sched.h: In function 'task_cpu':
include/linux/sched.h:2129:45: error: 'const struct thread_info' has no member named 'cpu'
 2129 |         return READ_ONCE(task_thread_info(p)->cpu);
      |                                             ^~

with many follow-up errors.

bisect points to commit (merge) 01463374c50e ("Merge tag
'cpu-to-thread_info-v5.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux" as the culprit,
and reverting that merge does indeed fix the problem.
