implementation had -- the format used would not actually limit the length
of the string output.  This new implementation uses a local buffer to deal
with it -- even with this additional copying it is much faster than the

The current implementation of __pa() for 64-bits kernels with 32-bits

PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space.

When the value in CKSEG0 space is used, it doesn't take into account
of PHYS_OFFSET. Even worse we can't redefine this value.

The patch restores CPHYSADDR() but in __pa()'s implementation because
it removes the need of 2 PAGE_OFFSET.

OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So
this patch assumes there's no need to deal with such kernel in 64-bits
