Pull x86 percpu updates from Ingo Molnar: - Enable the named address spaces based percpu accessors optimization on all GCC versions that contain this feature, detected through a build-time testcase. This effectively enables the feature on GCC 6, GCC 7 and GCC 8 versions. - Fix operand constraint modifier in __raw_cpu_write() - Reorganize the per-CPU headers for better readability - Misc cleanups and fixes * tag 'x86-percpu-2024-07-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/percpu: Enable named address spaces for all capable GCC versions x86/percpu: Clean up <asm/percpu.h> vertical alignment details x86/percpu: Clean up <asm/percpu.h> a bit x86/percpu: Move some percpu accessors around to reduce ifdeffery x86/percpu: Rename percpu_stable_op() to __raw_cpu_read_stable() x86/percpu: Fix operand constraint modifier in __raw_cpu_write() x86/percpu: Introduce the __raw_cpu_read_const() macro x86/percpu: Unify percpu read-write accessors x86/percpu: Move some percpu macros around for readability x86/percpu: Introduce the pcpu_binary_op() macro
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.
