[PATCH v2] x86/setup: Add boot messages about cmdline builtins

[Tony Fischetti]

While the ability to override or append to the boot command line has
been added, the boot messages contain no information as to whether the
cmdline was manipulated by the build-time options. This patch, for x86,
adds boot messages specifying the intital cmdline, and the final cmdline
after possible manipulation via the kernel config.
