LSE atomic increments and decrements clobber the x0 and x1 registers, and since these registers are used in volatile inline assembly for SCM calls, GCC does not preserve their values across the atomic_inc() and atomic_dec() calls. This results in x0 and x1 containing garbage values before and after the SCM call, breaking it entirely. Wrapping the atomic_inc() and atomic_dec() outside the SCM call functions fixes the issue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
