# LFS/CLFS Build notes
#
# You will also need to copy over asm-generic to ensure you have all the
# necessary headers. In LLH they asm-generic these into the asm-{architecture}
# so there is no asm-generic.
#
# Headers Lists
# As of version 01.00 we have removed the headers lists from the scripts
# and put them into separate text files in lists directory. The file format
# is one header per line.
#
# Programs Required
#
# This version requires unifdef - get it at
#
# http://ftp.debian.org/debian/pool/main/u/unifdef/
#
#
# Conversion Process
#
# Removal of __KERNEL__ - These tags are only during the build of the kernel
#
# Conversion u and s variables to userspace variables is the following link
# for more information http://www.linuxdevices.com/articles/AT5340618290.html
#
# Removal of <linux/config.h> - Not needed for userspace contains kernel build
# information.
#
# Conversion of linux to __linux__ - converts to a userspace usable
#
# Removal of __iomem
# for more information http://lwn.net/Articles/102232/
#
# version.h is created so that all the kernel versioning information
# is available
#
# compiler.h is removed
#
#
# I386 Specific
#
#
# MIPS Specific
#
# CONFIG_64BIT and CONFIG_32BIT are not defined in userspace so we use
# __mips64.
#
# Make atomic.h the same as LLH.
#
#
# Sparc Specific
#
# RAW Headers use variables from the configuration to get the PAGE SIZE
# so we use a function that exists in glibc to figure it out.
