Today LOAD_REG_IMMEDIATE() is a basic #define which loads all
parts on a value into a register, including the parts that are NUL.
This means always 2 instructions on PPC32 and always 5 instructions
on PPC64. And those instructions cannot run in parallele as they are
updating the same register.
Optimise LOAD_REG_IMMEDIATE_SYM() using a temporary register to
parallelise operations.
It reduces the path from 5 to 3 instructions.

Once ppc_md.iounmap() is gone, iounmap() remains the only user of
__iounmap() and iounmap() does nothing else than calling __iounmap().
So drop iounmap() and make __iounmap() the new iounmap().

ppc_md.ioremap() is only used for I/O workaround on CELL platform,
so indirect function call can be avoided.
This patch reworks the io-workaround and ioremap() functions to
use the global 'io_workaround_inited' flag for the activation
of io-workaround.
When CONFIG_PPC_IO_WORKAROUNDS or
__ioremap() is similar to ioremap_prot() except that ioremap_prot()
does a few sanity changes in addition.
The flags used by PS3 are not impacted by those changes so for
PS3 both functions are equivalent.
At the same time, drop parts of the comment that have been invalid
since commit
ioremap(), ioremap_wc() and ioremap_coherent() are now identical on
PPC32 and PPC64 as iowa_is_active() will always return false on
PPC32. Move them into a new common location called ioremap.c

Create a do_ioremap() function that calls get_vm_area and

There's wrong bitmap considered when checking
for cpu count of specific node.
We do the needed computation for 'set' variable,
but at the end we use the 'c2c_he->cpuset' weight,
which shows misleading numbers.
