A single commit that uses "arch_" atomic operations to avoid the instrumentation that comes with the non-"arch_" versions. In preparation for that commit, it also has another commit that makes these "arch_" atomic operations available to generic code. Without these commits, KCSAN uses can see pointless errors. Both from Peter Zijlstra. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAl74qe4ACgkQEsHwGGHe VUruxhAApxHnsIX4IFm4cBaSMMsXCGpifM3EOd3S1PPqxWQxLfrDpc/SgW4hvJja y144m/HQVvHkO8DAqWaC5lNmILjZhZeR1ToRrtqsFVzedlORaXgFJQzojjOBBCWi kwtrqVDb4dw+RBQdj6hrknnsivdAlDVFHYCxQuBpNQ/NN4M9l0nwxPRVpTdcFtw0 Yv6ttpDeo8/XJ12OwiFINWnQT7F1n6CoyvdH+zQayvP+2qK8sq3sYVN4DiTC2Jyk 9YpnR9ubl4jGz78+l2IrhhHw0zcHutGy2OVMXMYYvqZVzcp7QCpXFCP7MY00R6Br 1eyxzMJX3j9rxDcreNTFZQFqQsCSfla3SMJIHFT1PHiw2O1ZVXp4EUaHb6eCy/nb IMgRd37mRCQovE267+LmDMNovSbRXGFu/qhu7QPaKQizqfYTbAzGULbttHJr6P7i ciQRG6ZfpbqflsezlijmhDTXI/oK/prn5apo8g6IVAxVBINzpu01+xszpuOKdCg0 CGliJRShIXwPCAPacq0aFtauRt3RVpbEWOXj3GZU4yof/8wnHOAPZ0/HmFeKmO+4 BIaa7QASvYUfczVv/Fi0FKdU6c0jQGDCUxVi1XJpxNG0XSiayGEPyN4Y0wDNHuWg H+9MPAUhGoyDoMPRBjSKIVzNF7bLJ8VMe3GUBrFcJY+BVLhfXUE= =amVp -----END PGP SIGNATURE----- Merge tag 'rcu_urgent_for_5.8_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull RCU-vs-KCSAN fixes from Borislav Petkov: "A single commit that uses "arch_" atomic operations to avoid the instrumentation that comes with the non-"arch_" versions.

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.
