Subject: [PATCH 01/68] sh: Split out CPU topology initialization.
Split out the CPU topology initialization to a separate file,
and switch it to a percpu type, rather than an NR_CPUS array.
At the same time, switch to only registering present CPUs,
rather than using the possible CPU map.

Subject: [PATCH 02/68] sh: __user annotations for __get/__put_user().
This adds in some more __user annotations. These weren't being
handled properly in some of the __get_user and __put_user paths,
so tidy those up.

This fixes up much of the machvec handling, allowing for it to be
overloaded on boot. Making practical use of this still requires
some Kconfig munging, however.

Subject: [PATCH 05/68] sh: Rework CPU/board dependencies.
This was a big mess, rework the logic a bit so that we constrain
to a particular subtype and figure out the board support based
on that. This makes building subtype specific kernels supporting
multiple boards possible again.

Subject: [PATCH 07/68] sh: Get multiple boards in one image working again.
This tidies up the build rules and permits multiple boards to be
linked in to the same kernel. The earlier Kconfig work ensures that
the CPU configuration is consistent across the boards, as this is
the only thing that we can't do dynamically.

Subject: [PATCH 08/68] sh: Kill off machvec aliases.
We now throw all of the machvecs in to .machvec.init and either
select one on the command line, or copy out the first (and
usually only) one to sh_mv. The rest are freed as usual.
This gets rid of all of the silly sh_mv aliasing and makes the
selection explicit rather than link-order dependent.

Subject: [PATCH 09/68] sh: Rip out special unknown machvec.
This kills off the BareCPU board as a "special" machvec, rather,
we leave this as a default for when no other vector is available,
or when we want to use it in combination with other vectors for
testing with generic ops. As sh_mv is copied out anyways (or
overloaded when an alternate vector is explicitly selected), this
doesn't consume any additional memory.
The generic machvec can be forcibly selected with sh_mv=generic,
or by not having any other boards enabled.

Subject: [PATCH 10/68] sh: Fix SH-4 CPU selects.
Now that select no longer works for selecting the "closest" CPU,
we have to explicitly reference the precise sub-type in the few
places where it actually matters (presently only setup code and
some legacy sh-sci cruft).

Slub currently defaults to 8-byte alignment for the kmalloc
and slab minalign values, where 4 will suffice. In the slab
case BYTES_PER_WORD == 4 already, so defining the minalign
values outright doesn't cause any regressions there either.

Subject: [PATCH 26/68] sh: URAM node support for SH7722.
This adds the URAM block on SH7722 as a separate node.
Sparsemem is required for this, or it can simply be disabled
by explicitly selecting a flatmem model.

Subject: [PATCH 29/68] sh: Fix up cpu to node mapping in sysfs.
Currently cpu_to_node() is always 0 in the UP case, though
we do want to have the CPU association linked in under sysfs
even in the cases where we're only on a single CPU.
Fix this up, so we have the cpu0 link on all of the available
nodes that don't already have a CPU link of their own.

Subject: [PATCH 35/68] sh: Tidy up dependencies for SH-2 build.
SH-2 can presently get in to some pretty bogus states, so
we tidy up the dependencies a bit and get it all building
again.
This gets us a bit closer to a functional allyesconfig
and allmodconfig, though there are still a few things to
fix up.

Subject: [PATCH 38/68] sh: Kill off broken dma page ops.
There's no point in keeping these around, they've been broken
for some time, and the dmaenging/async_tx framework provides a
far more reasonable interface.

Subject: [PATCH 40/68] sh: rework intc2 code
The shared intc2 code currently contains cpu-specific #ifdefs.
This is a tad unclean and it prevents us from using the shared code
to drive board-specific irqs on the se7780 board.
This patch reworks the intc2 code by moving the base addresses of
the intc2 registers into struct intc2_desc. This new structure also
contains the name of the controller in struct irq_chip. The idea
behind putting struct irq_chip in there is that we can use offsetof()
to locate the base addresses in the irq_chip callbacks.
One logic change has been made - the original shared intc2 code
enabled the interrupts by default but with this patch they are all
disabled by default.

Subject: [PATCH 41/68] sh: Only support PMB for SH-X cores.
We don't have a PMB for SH-X2 or later, so only enable it for
the few CPUs that support it. Fixes up the boot for SH4AL-DSP.

Subject: [PATCH 42/68] sh: rework ipr code
This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.
One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.

From fc1d4c9c3761ca8db52b647c6a4ba50771900a12 Mon Sep 17 00:00:00 2001
From: Kaz Kojima <kkojima@rr.iij4u.or.jp>
Date: Mon, 18 Jun 2007 13:58:32 +0900
Subject: [PATCH 44/68] sh: Fix up futex implementation.
SH is able to support a complete futex implementation on UP by way
of gUSA. However, IRQ toggling must be done for the old CPUs that
don't have movli.l/movco.l (LL/SC) instructions. Provide a default
implementation that does this, so it's possible to optimize for
newer CPUs.
Follows the same scheme as the current asm-sh/atomic-*.h headers.

Subject: [PATCH 45/68] sh: Check oops_may_print() in unhandled fault.
Only print out pgd/pte data in the oops path if oops_may_print()
holds true. Follows the i386 implementation.

Subject: [PATCH 46/68] sh: Fix up cf-enabler dependency for SE boards.
This was using CONFIG_SH_SOLUTION_ENGINE, where we really wanted
CONFIG_SOLUTION_ENGINE. While we're at it, move the whole CF
enabler mess somewhere better suited.

Subject: [PATCH 48/68] sh: Hook up hard_smp_processor_id() for INTC2 block.
We need to know the CPU ID in order to calculate the mask and ack
registers effectively. Stub this in for UP.

Subject: [PATCH 52/68] sh: Correct __xdiv64_32/div64_32 return value size.
These should be returning a uint32_t, whereas they were erroneously
returning a u64 before. As the register sizes are 32-bits, this doesn't
really make a lot of sense.

A few minor things were broken here. fix and var screeninfo should have
been __devinitdata, board_list[] gets renamed to board_driver[] so the
modpost matching does the right thing, and we properly discard some of
the unused exit sections.

Subject: [PATCH 55/68] fb: pvr2fb: A few more __devinit annotations for PCI.
In the PCI + hotplug case we end up with some bogus references between
the PCI driver path and the DC path. In order to fix this, we have to
rework the common init path for __devinit, as well as moving all of the
data that it references to __devinidata.

Subject: [PATCH 57/68] sh: Drop -Wa,-dsp for DSP tuning.
We already hand off the proper ISA variant with the dsp specifier
appended, so we don't need to explicitly set -dsp. This causes some
confusion with certain toolchains that are restricted to -dsp family
opcodes artificially.

Subject: [PATCH 59/68] sh: Don't let SH-4A clobber SH-4 CFLAGS.
Older compilers don't support the -m4a{,nofpu} flags, which has the
side-effect of allowing FP operations to be emitted. Switch this to
incremental tuning, so we at least have -m4-nofpu as a fallback for
the gcc3 toolchains.
Without this, certain modules emit references to __udivsi3_i4 and
__sdivsi3_i4.

Subject: [PATCH 64/68] sh: fix race in parallel out-of-tree build
Depending on which of the three dependencies for archprepare (in
arch/sh/Makefile) get built first, the directory include/asm-sh may or
may not exist when the maketools target is built. If the directory does
not exist, awk will fail to generate machtypes.h. This patch fixes this
by creating the directory before awk is executed.

Subject: [PATCH 65/68] sh: Export div symbols for GCC 4.2 and ST GCC.
GCC 4.2 can emit integer variants of the FP division routines, so
these need to be exported in order to keep the modules happy.
4.1.x versions of the ST compiler have these things backported,
and so also generate these symbols (whereas vanilla gcc 4.1.x
does not), so handle the __GNUC_STM_RELEASE__ case to accomodate
updated versions of the 4.1.x toolchain.
