Originally, generated-y and genhdr-y had different meaning, like
follows:
- generated-y: generated headers (other than asm-generic wrappers)
- header-y : headers to be exported
- genhdr-y : generated headers to be exported (generated-y + header-y)
Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), headers under UAPI directories are all exported.
So, there is no more difference between generated-y and genhdr-y.
We see two users of genhdr-y, arch/{arm,x86}/include/uapi/asm/Kbuild.
They generate some headers in arch/{arm,x86}/include/generated/uapi/asm
directories, which are obviously exported.
Replace them with generated-y, and abolish genhdr-y.
