Merge tag 'kbuild-uapi-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild UAPI updates from Masahiro Yamada:
"Improvement of headers_install by Nicolas Dichtel.

It has been long since the introduction of uapi directories, but the
de-coupling of exported headers has not been completed. Headers listed
in header-y are exported whether they exist in uapi directories or
not. His work fixes this inconsistency.

All (and only) headers under uapi directories are now exported. The
asm-generic wrappers are still exceptions, but this is a big step
forward"

 	that may be shared between individual architectures.
 	The recommended approach how to use a generic header file is
 	to list the file in the Kbuild file.
-	See "7.4 generic-y" for further info on syntax etc.
+	See "7.3 generic-y" for further info on syntax etc.
 
 --- 6.11 Post-link pass
 
···
 - drop include of compiler.h
 - drop all sections that are kernel internal (guarded by ifdef __KERNEL__)
 
-Each relevant directory contains a file name "Kbuild" which specifies the
-headers to be exported.
+All headers under include/uapi/, include/generated/uapi/,
+arch/<arch>/include/uapi/ and arch/<arch>/include/generated/uapi/
+are exported.
+
+A Kbuild file may be defined under arch/<arch>/include/uapi/asm/ and
+arch/<arch>/include/asm/ to list asm files coming from asm-generic.
 See subsequent chapter for the syntax of the Kbuild file.
 
-	--- 7.1 header-y
+	--- 7.1 no-export-headers
 
-	header-y specifies header files to be exported.
-
-		Example:
-			#include/linux/Kbuild
-			header-y += usb/
-			header-y += aio_abi.h
-
-	The convention is to list one file per line and
-	preferably in alphabetic order.
-
-	header-y also specifies which subdirectories to visit.
-	A subdirectory is identified by a trailing '/' which
-	can be seen in the example above for the usb subdirectory.
-
-	Subdirectories are visited before their parent directories.
+	no-export-headers is essentially used by include/uapi/linux/Kbuild to
+	avoid exporting specific headers (e.g. kvm.h) on architectures that do
+	not support it. It should be avoided as much as possible.
 
 	--- 7.2 genhdr-y
 
-	genhdr-y specifies generated files to be exported.
-	Generated files are special as they need to be looked
-	up in another directory when doing 'make O=...' builds.
+	genhdr-y specifies asm files to be generated.
 
 		Example:
-			#include/linux/Kbuild
-			genhdr-y += version.h
+			#arch/x86/include/uapi/asm/Kbuild
+			genhdr-y += unistd_32.h
+			genhdr-y += unistd_64.h
+			genhdr-y += unistd_x32.h
 
-	--- 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
···
 		Example:
 			#arch/x86/include/asm/Kbuild
 			generated-y += syscalls_32.h
+
+	--- 7.5 mandatory-y
+
+	mandatory-y is essentially used by include/uapi/asm-generic/Kbuild.asm
+	to define the minimun set of headers that must be exported in
+	include/asm.
+
+	The convention is to list one subdir per line and
+	preferably in alphabetic order.
