headers_install.pl
#!/usr/bin/perl -w
#
# headers_install prepare the listed header files for use in
# user space and copy the files to their destination.
#
# Usage: headers_install.pl readdir installdir arch [files...]
# readdir: dir to open files
# installdir: dir to install the files
# arch: current architecture
# arch is used to force a reinstallation when the arch
# changes because kbuild then detect a command line change.
# files: list of files to check
#
# Step in preparation for users space:
# 1) Drop all use of compiler.h definitions
# 2) Drop include of compiler.h
# 3) Drop all sections defined out by __KERNEL__ (using unifdef)
