Eliminate a useless task_work on execve by moving the call to rseq_set_notify_resume() from sched_mm_cid_after_execve() to the error path of bprm_execve(). The call to rseq_set_notify_resume() from sched_mm_cid_after_execve() is pointless in the success case, because rseq_execve() will clear the rseq pointer before returning to userspace. sched_mm_cid_after_execve() is called from both the success and error paths of bprm_execve(). The call to rseq_set_notify_resume() is needed on error because the mm_cid may have changed. Also move the rseq_execve() to right after sched_mm_cid_after_execve() in bprm_execve().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
