# sed script to filter out symbols that are not needed for System.map,

# or not suitable for kallsyms. The input should be 'nm -n <file>'.

#

# System.map is used by module-init tools and some debugging

# tools to retrieve the actual addresses of symbols in the kernel.

#

# Usage

# mksysmap vmlinux System.map





#####

# Generate System.map (actual filename passed as second argument)

# The following refers to the symbol type as per nm(1).



# readprofile starts reading symbols when _stext is found, and

# continue until it finds a symbol which is not either of 'T', 't',

# 'W' or 'w'.
