Move hctx cpuhp add/del out of queue freezing for not connecting freeze lock with cpuhp locks, then lockdep warning can be avoided. This way is safe because both needn't queue to be frozen and scheduler switch isn't allowed, with same reason for moving hctx debugfs/sysfs register out of queue freeze.

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.
