[ Upstream commit df359f0d09dc029829b66322707a2f558cb720f7 ] Other parts of the kernel expect these nonblocking EFI callbacks to exist and crash when running under Xen. Since the implementations of xen_efi_set_variable() and xen_efi_query_variable_info() do not take any locks, use them for the nonblocking callbacks too.

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.
