Add minimum support for the Blackfin relocations, since we don't have
enough space in each reloc. The idea is to store a value with one
relocation so that subsequent ones can access it.Actually, this patch is required for Blackfin. Currently if BINFMT_FLAT is
enabled, git-tree kernel will fail to compile.Signed-off-by: Bernd Schmidt

The current SH DMA API is somewhat broken, not correctly matching
virtual channel to the correct SH DMAC. This wasn't noticeable when
using g2 DMA for the sound driver - one channel 0 is as good as any
other! - but caused the pvr2 driver to fail.This patch fixes the pvr2 problem and consequently fixes the sound
driver to ensure it continues to function.Signed-off by: Adrian McMenamin

This wires up kmap_coherent() and kunmap_coherent() on SH-4, and
moves away from the p3map_mutex and reserved P3 space, opting to
use fixmaps for colouring instead.The copy_user_page()/clear_user_page() implementations are moved
to this, which fixes the nasty blowups with spinlock debugging
as a result of having some of these calls nested under the page
table lock.Signed-off-by: Paul Mundt

This patch converts the cpu specific 7750 setup code to use the
new intc controller. Many new vectors are added and multiple
processor variants including 7091, 7750, 7750s, 7750r, 7751 and
7751r should all have the correct vectors hooked up.IRLM interrupts can be enabled using ipr_irq_enable_irlm() which
now is marked as __init.Signed-off-by: Magnus Damm

This patch converts the cpu specific 7780 setup code to use the
new intc controller. Many new vectors are added and also support for
external interrupt sense configuration. So with this patch it is now
possible to configure external interrupt pins as edge or level
triggered using set_irq_type().No external interrupts are registered by default.
Use plat_irq_setup_pins() to select between IRQ or IRL mode.This patch also fixes the Alarm IRQ for the RTC.

This patch cleans up solution engine 7722 specific interrupt code.

This is the second version of the shared interrupt controller patch
for the sh architecture, fixing up handling of intc_reg_fns[].The three main advantages with this controller over the existing
ones are:- Both priority (ipr) and bitmap (intc2) registers are
supported
- External pin sense configuration is supported, ie edge
vs level triggered
- CPU/Board specific code maps 1:1 with datasheet for
easy verificationThis controller can easily coexist with the current IPR and INTC2
controllers, but the idea is that CPUs/Boards should be moved over
to this controller over time so we have a single code base to
maintain.Signed-off-by: Magnus Damm

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.

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.Signed-off-by: Magnus Damm
