3 # headers_install prepare the listed header files for use in
4 # user space and copy the files to their destination.
6 # Usage: headers_install.pl readdir installdir arch [files...]
7 # readdir: dir to open files
8 # installdir: dir to install the files
9 # arch: current architecture
10 # arch is used to force a reinstallation when the arch
11 # changes because kbuild then detect a command line change.
12 # files: list of files to check
14 # Step in preparation for users space:
15 # 1) Drop all use of compiler.h definitions
16 # 2) Drop include of compiler.h
17 # 3) Drop all sections defined out by __KERNEL__ (using unifdef)
