mn10300: Fix crash just after starting userspace on !CONFIG_PREEMPT

2013-09-10T21:54:59+00:00

The mn10300 kernel crashes just after starting userspace programs, if CONFIG_PREEMPT is disabled: Freeing unused kernel memory: 96K (90286000 - 9029e000) MISALIGN: 97c33ff9: unsupported instruction f MISALIGN: 97c33ff9: unsupported instruction f MISALIGN: 97c33ff9: unsupported instruction f : This fixes the problem that was introduced by commit d17fc238ac14 ("MN10300: Enable IRQs more in system call exit work path").

MN10300: Enable IRQs more in system call exit work path

2013-05-30T04:38:48+00:00

Enable IRQs when calling schedule() for TIF_NEED_RESCHED and do_notify_resume(). If interrupts are enabled during do_notify_resume(), a warning can be seen (see lower down). Whilst we're at it, resume_userspace can be made local to entry.S as it is not called outside of there and it can be merged with the part of work_resched that occurs after schedule() is called.

MN10300: Fix ret_from_kernel_thread

2013-05-30T04:38:48+00:00

ret_from_kernel_thread needs to set A2 to the thread_info pointer before jumping to syscall_exit. Without this, we never correctly start userspace. This was caused by the rejuggling of the fork/exec paths in commit ddf23e87a804 ("mn10300: switch to saner kernel_execve() semantics") Reported-by: Ken Cox Signed-off-by: David Howells Acked-by: Ken Cox Acked-by: Al Viro Signed-off-by: Linus Torvalds

All Arch: remove linkage for sys_nfsservctl system call

The nfsservctl system call is now gone, so we should remove all linkage for it. Signed-off-by: NeilBrown Signed-off-by: J. Bruce Fields Signed-off-by: Linus Torvalds
