2414b86d21 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.

8cb661d6a4 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.

aab1b16a61 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.

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

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

data that it references to __devinidata.

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.

68abdbbb03 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.

This is a tad unclean and it prevents us from using the shared code
