sh: fix wrong icache/dcache address-array start addr in cache-debugfs.
This patch fixes a icache/dcache address-array start address while
dumping its entires in debugfs. Perviously the code was attempting to
remember the address in static variable, which is no more required
for debugfs, as the function can be executed in one pass.
Without this patch the start address ends up in wrong place and the
/sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

sh: provide generic arch_debugfs_dir.
While sh previously had its own debugfs root, there now exists a
common arch_debugfs_dir prototype, so we switch everything over to
that. Presumably once more architectures start making use of this
we'll be able to just kill off the stub kdebugfs wrapper.

sh: Mass ctrl_in/outX to __raw_read/writeX conversion.
The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

sh: Kill off the special uncached section and fixmap.
Now that cached_to_uncached works as advertized in 32-bit mode and we're
never going to be able to map < 16MB anyways, there's no need for the
special uncached section. Kill it off.

Fix debugfs_create_file's error checking method for arch/sh/mm/
debugfs_create_file() returns NULL if an error occurs, returns -ENODEV

sh: fix seq_file memory leak
When using single_open(), single_release() should be used instead
of seq_release(), otherwise there is a memory leak.

sh: Preparation for uncached jumps through PMB.
Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

[PATCH] mark struct file_operations const 2
Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.
