uapi: Allow automatic generation of uapi/asm/ header files
Catalin Marinas [Wed, 17 Oct 2012 11:25:44 +0000 (12:25 +0100)]
Several arch/*/include/uapi/asm/* header simply include the
corresponding <asm-generic/*> file. This patch allows such files to be
specified in uapi/asm/Kbuild via "generic-y += ..." to be automatically
generated (similar to asm/Kbuild).
