Depends on how small/large the chunks should/may be.
My intention is to remove duplicated rdmsr/wrmsr functions
and make rdmsr usable as a real C function.
The large part of changes are the bit-operations surrounding
the rdmsr/wrmsr code lines.
The sent patches replace rdmsr/wrmsr by rdmsrl/wrmsrl
step by step. When this is done, rdmsr/wrmsr can be killed.
