In x86's include/asm/Kbuild three entries are appended to the genhdr-y make
variable:
genhdr-y += unistd_32.h
genhdr-y += unistd_64.h
genhdr-y += unistd_x32.h
The same entries are also appended to that variable in
include/uapi/asm/Kbuild. So commit:
10b63956fc ("UAPI: Plumb the UAPI Kbuilds into the user header installation and checking")
... removed these three entries from include/asm/Kbuild. But, apparently, some
merge conflict resolution re-added them.
The net effect is, in short, that the genhdr-y make variable contains these
file names twice and, as a consequence, that the corresponding headers get
installed twice. And so the build prints:
INSTALL usr/include/asm/ (65 files)
... while in reality only 62 files are installed in that directory.
Nothing breaks because of all that, but it's a good idea to finally remove
these unneeded entries nevertheless.
