# 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)
