Another bunch of smallish kbuild updates.

o Fix parrallel build
o Add make C=2 to force check of C code with sparse
o Fiw warnings in binoffset
o Removed dreadful check for undefined symbols in vmlinux
o Delete last occurence of HEAD in kbuild
o Add comments to Makefile.clean
o Introduce CHECKFLAGS enabling make CHECK=mysparse

Patches follows (most have been sent to lkml before).

Significant outstanding items in kbuild land is mainly package
handling.
Several issues needs to be adressed:
- Rename debian directory to deb/debian
- Utilise parallel build with make rpm
- Add one more prm package variant
- Add tar-pkg, targz.pkg
- Find a better way to identify relevant binaries to include in rpm, deb
	- Current KBUILD_IMAGE proves not to be good enough

And a patch relate to control alignment in gcc produced code.
Needs to land some consolidation stuff first. Planning to rename
check_gcc to gcc_option, and include a new one named gcc_option_ok.

For ppc we have a problem with as trashing /dev/null.
This is apperantly due to this code:
BAD_AGCC_AS :=  $(shell echo mftb 5 | $(AS) -mppc -many -o /dev/null >/dev/null 2>&1 && echo 0 || echo 1)

It seem like as deletes /dev/null and recreate it.
Not good if run as root - which is needed for modules_install for example.

Would it be considered acceptable to start using mktemp to generate temporary
filenames as part of a normal kernel build?
I do not fully understand the eventual security issues around this!

	Sam

Hi,
I will really appreciate if someone can point me to documents, notes, papers
etc. about the enhancements in the networking stack of kernel 2.6,
guidelines for NIC driver development to make use of such enhancements,
ipsec offload, tcp offload etc.

Thanks,
Imran.
