Pull kernel_clone() updates from Christian Brauner:
"During the v5.9 merge window we reworked the process creation
codepaths across multiple architectures. After this work we were only
left with the _do_fork() helper based on the struct kernel_clone_args
calling convention. As was pointed out _do_fork() isn't valid
kernelese especially for a helper that isn't just static.This series removes the _do_fork() helper and introduces the new
kernel_clone() helper. The process creation cleanup didn't change the
name to something more reasonable mainly because _do_fork() was used
in quite a few places. So sending this as a separate series seemed the
better strategy.I originally intended to send this early in the v5.9 development cycle
after the merge window had closed but given that this was touching
quite a few places I decided to defer this until the v5.10 merge
window"* tag 'kernel-clone-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
sched: remove _do_fork()
tracing: switch to kernel_clone()
kgdbts: switch to kernel_clone()
kprobes: switch to kernel_clone()
x86: switch to kernel_clone()
sparc: switch to kernel_clone()
nios2: switch to kernel_clone()
m68k: switch to kernel_clone()
ia64: switch to kernel_clone()
h8300: switch to kernel_clone()

The old _do_fork() helper is removed in favor of the new kernel_clone() helper.
The latter adheres to naming conventions for kernel internal syscall helpers.Signed-off-by: Christian Brauner

There are several files that I was unable to find a proper place
for them, and 3 ones that are still in plain old text format.Let's place those stuff behind the carpet, as we'd like to keep the
root directory clean.We can later discuss and move those into better places.

The regs_return_value() returns "unsigned long" or "long" value. But the
retval is int type now, it may cause overflow, the log may becomes:[ 2911.078869] do_brk returned -2003877888 and took 4620 ns to execute
This patch converts the retval to "unsigned long" type, and fixes the
overflow issue.Link: http://lkml.kernel.org/r/1464143083-3877-4-git-send-email-shijie.huang@arm.com

We prefer to use the pr_* to print out the log now, this patch converts
the printk to pr_info. In the error path, use the pr_err to replace the

Commit 3033f14ab78c ("clone: support passing tls argument via C rather
than pt_regs magic") introduced _do_fork() that allowed to pass @tls
parameter.The old do_fork() is defined only for architectures that are not ready
to use this way and do not define HAVE_COPY_THREAD_TLS.Let's use _do_fork() in the kprobe examples to make them work again on
all architectures.Signed-off-by: Petr Mladek

Move kprobes examples from Documentation/kprobes.txt to under samples/.
Patch originally by Randy Dunlap.o Updated the patch to apply on 2.6.25-rc3
o Modified examples code to build on multiple architectures. Currently,
the kprobe and jprobe examples code works for x86 and powerpc
o Cleaned up unneeded #includes
o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break
on archs that don't have kretprobes
o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES
o Included Andrew Morton's cleanup based on x86-git
o Modified kretprobe_example to act as a arch-agnostic module to
determine routine execution times:
Use 'modprobe kretprobe_example func=' to determine
execution time of func_name in nanoseconds.Signed-off-by: Randy Dunlap
