- Prevent an unconditional interrupt enable in a futex helper function
which can be called from contexts which expect interrupts to stay
disabled across the call.
- Don't modify lockdep chain keys in the validation process as that
causes chain inconsistency.

Pull locking fixes from Thomas Gleixner:
"Two fixes for the locking subsystem:
- Prevent an unconditional interrupt enable in a futex helper
function which can be called from contexts which expect interrupts
to stay disabled across the call
- Don't modify lockdep chain keys in the validation process as that
causes chain inconsistency"
* tag 'locking-urgent-2020-11-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
lockdep: Avoid to modify chain keys in validate_chain()
futex: Don't enable IRQs unconditionally in put_pi_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.
