Paul Mundt 8f82f0c702 sh: Fix up breakage from asm-generic/pgtable.h changes.
We require a forward declaration for mm_struct:

Magnus Damm fac6c2a891 sh: sh7372 SH4AL-DSP probe support
Add probe support for the sh7372 SH4AL-DSP core.

The most common use case for this is when the system
boots from the ARM core in the sh7372 and uses the
SH core for application offload as a slave CPU.

May also be used to boot the sh7372 from the SH core.

Paul Mundt efb3e34b61 sh: Fix up legacy PTEA space attribute mapping.
When p3_ioremap() was converted to ioremap_prot() there was some breakage
introduced where the 29-bit segmentation logic would trap the area range
and return an identity mapping without having allowed the area
specification to force mapping through page tables. This wires up a PCC
mask for pgprot verification to work out whether to short-circuit the
identity mapping on legacy parts, restoring the previous behaviour.

Paul Mundt 11e1ed6e88 sh: Stub out legacy PCC pgprot encoding for X2 TLBs.
Presently it's still possible to reference the PAGE_KERNEL_PCC pgprot
encoding on X2 TLBs which simply don't support it at all. Convert this
over to follow the nommu behaviour and simply hand back an invalid pgprot
value so we error out properly.

A definition like:

#define regs_return_value(regs)	((regs)->regs[0])

called with regs_return_value(foo) will be preprocessed to:

((foo)->foo[0])
        ^^^
So to fix this to ensure the preprocessor compiles such calls correctly.

Paul Mundt 1dee92bba3 sh: Tidy up SH-4A unaligned load support.
The current implementation was rather tied to the packed_struct.h
definitions, which immediately began to clash when the packed_struct.h
types changed and drivers began to include packed_struct.h directly.

In order to support this sort of use it's necessary to get out of the way
with regards to namespace collisions, and at the same time we can also
kill off some duplicate code now that the unaligned headers are a bit
more broken out.
