- --- 7.3 destination-y
-
- When an architecture has a set of exported headers that needs to be
- exported to a different directory destination-y is used.
- destination-y specifies the destination directory for all exported
- headers in the file where it is present.
-
- Example:
- #arch/xtensa/platforms/s6105/include/platform/Kbuild
- destination-y := include/linux
-
- In the example above all exported headers in the Kbuild file
- will be located in the directory "include/linux" when exported.

- --- 7.4 generic-y
+ --- 7.3 generic-y
If an architecture uses a verbatim copy of a header from
include/asm-generic then this is listed in the file
Example: termios.h
#include <asm-generic/termios.h>
- --- 7.5 generated-y
+ --- 7.4 generated-y
If an architecture generates other header files alongside generic-y
wrappers, and not included in genhdr-y, then generated-y specifies
include $(kbuild-file)
# called may set destination dir (when installing to asm/)
-_dst := $(if $(destination-y),$(destination-y),$(if $(dst),$(dst),$(obj)))
+_dst := $(if $(dst),$(dst),$(obj))
old-kbuild-file := $(srctree)/$(subst uapi/,,$(obj))/Kbuild
ifneq ($(wildcard $(old-kbuild-file)),)
