[ Upstream commit a0ffa8115e1ea9786b03edc3f431d2f4ef3e7a2e ] Masks the "DSP Virtual Mailbox 2 write" interrupt when before issuing the hibernate command to the DSP. The interrupt is unmasked when exiting runtime suspend as it is required for DSP operation. Without this change the DSP fires an interrupt when hibernating causing the system spin between runtime suspend and runtime resume.

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.
