Clang is particularly anal about signed vs unsigned comparisons and
doesn't like the fact that some ioctl numbers set the MSB, so we get
this error when trying to build vhost on aarch64:
drivers/vhost/vhost.c:1400:7: error: overflow converting case value to
switch condition type (3221794578 to 18446744072636378898)
[-Werror, -Wswitch]
case VHOST_GET_VRING_BASE:
3221794578 is 0xC008AF12 in hex
18446744072636378898 is 0xFFFFFFFFC008AF12 in hex
Fix this by using unsigned ints in the function signature for
vhost_vring_ioctl().

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.
