	=== 7 Kbuild syntax for exported headers

	=== 8 Kbuild Variables

	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 "7.2 generic-y" for further info on syntax etc.

--- 6.11 Post-link pass

        If the file arch/xxx/Makefile.postlink exists, this makefile

        will be invoked for post-link objects (vmlinux and modules.ko)

        for architectures to run post-link passes on. Must also handle

        the clean target.

        This pass runs after kallsyms generation. If the architecture

        needs to modify symbol locations, rather than manipulate the

        kallsyms, it may be easier to add another postlink target for

        .tmp_vmlinux? targets to be called from link-vmlinux.sh.

        For example, powerpc uses this to check relocation sanity of

        the linked vmlinux file.

=== 7 Kbuild syntax for exported headers

- 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.

See subsequent chapter for the syntax of the Kbuild file.

	--- 7.1 header-y

	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.

	--- 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.

All headers under include/uapi/, include/generated/uapi/,

arch/<arch>/include/uapi/ and arch/<arch>/include/generated/uapi/

are exported.

		Example:

			#include/linux/Kbuild

			genhdr-y += version.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.

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.

		Example:

			#arch/xtensa/platforms/s6105/include/platform/Kbuild

			destination-y := include/linux

	--- 7.1 no-export-headers

	In the example above all exported headers in the Kbuild file

	will be located in the directory "include/linux" when exported.

	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.

	--- 7.4 generic-y

	--- 7.2 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>

	--- 7.3 generated-y

	If an architecture generates other header files alongside generic-y

	wrappers, generated-y specifies them.

	This prevents them being treated as stale asm-generic wrappers and

	removed.

		Example:

			#arch/x86/include/asm/Kbuild

			generated-y += syscalls_32.h

	--- 7.4 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.

=== 8 Kbuild Variables

The top Makefile exports the following variables:
