Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal

Pull big execve/kernel_thread/fork unification series from Al Viro:
"All architectures are converted to new model. Quite a bit of that
stuff is actually shared with architecture trees; in such cases it's
literally shared branch pulled by both, not a cherry-pick.

A lot of ugliness and black magic is gone (-3KLoC total in this one):

- kernel_thread()/kernel_execve()/sys_execve() redesign.

We don't do syscalls from kernel anymore for either kernel_thread()
or kernel_execve():

kernel_thread() is essentially clone(2) with callback run before we
return to userland, the callbacks either never return or do
successful do_execve() before returning.

kernel_execve() is a wrapper for do_execve() - it doesn't need to
do transition to user mode anymore.

As a result kernel_thread() and kernel_execve() are
arch-independent now - they live in kernel/fork.c and fs/exec.c
resp. sys_execve() is also in fs/exec.c and it's completely
architecture-independent.

- daemonize() is gone, along with its parts in fs/*.c

- struct pt_regs * is no longer passed to do_fork/copy_process/
copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.

- sys_fork()/sys_vfork()/sys_clone() unified; some architectures
still need wrappers (ones with callee-saved registers not saved in
pt_regs on syscall entry), but the main part of those suckers is in
kernel/fork.c now."

"This tree removes ancient-386-CPUs support and thus zaps quite a bit
of complexity:

24 files changed, 56 insertions(+), 425 deletions(-)

... which complexity has plagued us with extra work whenever we wanted
to change SMP primitives, for years.

Unfortunately there's a nostalgic cost: your old original 386 DX33
system from early 1991 won't be able to boot modern Linux kernels
anymore. Sniff."
