Peter Zijlstra dca64f4bea cpuidle, intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE *again* 
[ Upstream commit 6d9c7f51b1 ]

So objtool found this bug:

  vmlinux.o: warning: objtool: intel_idle_irq+0x10c: call to trace_hardirqs_off() leaves .noinstr.text section

As per commit 32d4fd5751 ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE"):

  "must not have tracing in idle functions"

Clearly people can't read and tinker along until splat dissapears.
This straight up reverts commit d295ad34f2 ("intel_idle: Fix false
positive RCU splats due to incorrect hardirqs state").

It doesn't re-introduce the problem because preceding patches fixed it
properly.

Fixes: d295ad34f2 ("intel_idle: Fix false positive RCU splats due to incorrect hardirqs state")

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 Restructured Text 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.
