The size of swapper_pg_dir is 8k instead of 4k when using 64-bit PTEs
(CONFIG_PTE_64BIT).

Move to using PAGE_OFFSET instead of TASK_SIZE or KERNELBASE value on
6xx/40x/44x/fsl-booke to determine if the faulting address is a kernel or
user space address. This mimics how the macro is_kernel_addr() works.

It is just a C char array, so declare it thusly.

We get warnings like the following from the various ppc32 head*.S files:
WARNING: vmlinux.o(.text+0x358): Section mismatch: reference to .init.text:early_init (between 'skpinv' and 'interrupt_base')
WARNING: vmlinux.o(.text+0x380): Section mismatch: reference to .init.text:machine_init (between 'skpinv' and 'interrupt_base')

WARNING: vmlinux.o(.text+0x3ae): Section mismatch: reference to .init.text:start_kernel (between 'skpinv' and 'interrupt_base')
Added a .text.head section simliar to what other architectures do since
modpost already excludes this from its warnings.

4xx is a bit of a misnomer for certain things, as they really apply to PowerPC
40x only. Rename some of the files to clean this up.
