This series provides emulated one-byte cmpxchg() support for ARM using the cmpxchg_emu_u8() function that uses a four-byte cmpxchg() to emulate the one-byte variant. Similar patches for emulation of one-byte cmpxchg() for arc, sh, and xtensa have not yet received maintainer acks, so they are slated for the v6.12 merge window. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmaRtqcTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jNvAD/0WF6kmx5aQhom6/lcpM76ZWHG+n6VZ pYYkdnqCf43Z4qayJOd1PZxSF7T1H0+TS/NjdIlZSyRqDF4wJNo8Iotp5cudQ94L Pn08UYhw9FgUf3uee/a5FVKInLJ3BDEfZs/tHLy2nQKMse3EIuwD0LL9qh/+WEKY INjhcVqOkWvNQ7RqMj46rpAQTcjGw9LWB4UVzg9HhYc+YQYQGjhlv29/xU6/14GH ZuhkkMi5WvC6ZEAxEOXm9N3DVtOU/UrBENPt1alfEwifOprbysGf3825DoJpqm/z kTg0iy3LofYxLvj4cMeH731WKUMaUMErt4+XUQaWsa33qO6Ezj7FGKYjX2UoleS+ gWktHryvSFEQUH4SNTyYg4yKJYdtP7ynXTKk98EOEMoED4f5UBlBiVQduo7xuwSz A5CI4ZT89wOKtAWTQyMEXV9gQnrJLPe7lVbvn+I7x4XFxTYf1y5pvyv6KhlXKXXG +N+9c6ixkmBjrCzlWF7DeJfhr+rPjcVznzqNus2e4yyKy7vpTXlD3+vYjIgFgsrM +QOfDUZ3nuboPvLNJrOiIRVrZTjllRDODDkK+3kmGIivDKsrh5v36/rBcPO38RPS OttgIRfjkBcMsYKcsvtrsbPEwC+Z3vtoZXsT/Qf9Ok4pK1zy0bhEqW8ntHY9hePx NUwnK6bMqcH84A== =erj9 -----END PGP SIGNATURE----- Merge tag 'cmpxchg.2024.07.12a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull arm byte cmpxchg from Paul McKenney: "ARM: Provide one-byte cmpxchg emulation This provides emulated one-byte cmpxchg() support for ARM using the cmpxchg_emu_u8() function that uses a four-byte cmpxchg() to emulate the one-byte variant.

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.
