Linux kernel source tree

When build kernel with C=1, we get: arch/loongarch/kernel/process.c:234:46: warning: incorrect type in argument 1 (different address spaces) arch/loongarch/kernel/process.c:234:46: expected void *ptr arch/loongarch/kernel/process.c:234:46: got unsigned long [noderef] __percpu * arch/loongarch/kernel/process.c:234:46: warning: incorrect type in argument 1 (different address spaces) arch/loongarch/kernel/process.c:234:46: expected void *ptr arch/loongarch/kernel/process.c:234:46: got unsigned long [noderef] __percpu * arch/loongarch/kernel/process.c:234:46: warning: incorrect type in argument 1 (different address spaces) arch/loongarch/kernel/process.c:234:46: expected void *ptr arch/loongarch/kernel/process.c:234:46: got unsigned long [noderef] __percpu * arch/loongarch/kernel/process.c:234:46: warning: incorrect type in argument 1 (different address spaces) arch/loongarch/kernel/process.c:234:46: expected void *ptr arch/loongarch/kernel/process.c:234:46: got unsigned long [noderef] __percpu * Add __percpu annotation for __percpu_read()/__percpu_write() can avoid such warnings. __percpu_xchg() and other functions don't need annotation because their wrapper, i.e. _pcp_protect(), already suppresses warnings. Also adjust the indentations in this file.

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.
