# building a kernel module

# strict-aliasing - disables optimizations related to unions/casts

# no-common - will put globals uninitialized in .bss instead of common

# 		hence get link error if multiple declaration

# preferred-stack-boundary=2 -align stack to 2^2 byte boundary,

#		possible performance penalty for 64 bit data

# 		TBD, what does kernel use

# -D_I386_PTRACE_H was a workaround for a ptrace.h header file inclusion issue

# 		identify where needed and just put in that one makefile

# -include picks up special flags for SMP and MODVERSIONS, this allows portable

# kernel modules to be built for multiple system types from a single running
