[ Upstream commit43d281662f] The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to dynamically allocate a struct member, but this is normally intended for local variables. Building with clang, I get a warning for a few locations that check the address of the cpumask_var_t: drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] As far as I can tell, the code is still correct, as the truth value of the pointer is what we need in this configuration. To get rid of the warning, use cpumask_available() instead of checking the pointer directly.

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.
