[ Upstream commit62b06f8f42] Our irq_is_pending() helper function accesses multiple members of the vgic_irq struct, so we need to hold the lock when calling it. Add that requirement as a comment to the definition and take the lock around the call in vgic_mmio_read_pending(), where we were missing it before.

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.
