This patch updates the receive error code for muxed
interrupts in the sh-sci driver.Receive error interrupts may be generated by the hardware
if RE or REIE bits in SCSCR are set. Update the muxed
interrupt handling code to acknowledge error interrupts
if RE or REIE is set, instead of only acknowledging if
REIE is set.Without this patch error interrupts may be generated but
never acked resulting in a "nobody cared" crash.Signed-off-by: Magnus Damm

Presently this is special-cased for early initialization. While there are
situations where these static early initializations are still necessary,
with minor changes it is possible to use this for the regular ioremap
implementation as well. This allows us to kill off the special-casing for
the remap completely and to start tidying up all of the SH-5
special-casing in drivers.Signed-off-by: Paul Mundt

This adds preliminary support for the SH7786 CPU subtype.
While this is a dual-core CPU, only UP is supported for now. L2 cache
support is likewise not yet implemented.More information on this particular CPU subtype is available at:

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR
write. While on hardware it can be gauranteed that the read-and-clear
will happen prior to the character being written out, no such assumption
can be made under emulation. As this path happens with IRQs off and the
hardware itself doesn't care about the ordering, move the SCxTDR write
until after the read-and-clear.Signed-off-by: Vladimir Prus

…/git/tip/linux-2.6-tip
This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]). The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.* 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (178 commits)

This was added at a time when the compiler did a less than stellar job of
optimizing out dead code. These days this tends to be less of a concern,
so kill it all off.Signed-off-by: Paul Mundt

Presently this is conditionalized on sh, and disabled for sh64.
Now that SH-5 ties in to the clock framework, the sh64 exception
can be dropped. Additionally, ARM will want to use the same hooks
once SH-Mobile G3 grows clock framework support, so switch these
paths over to HAVE_CLK now.Once the H8 and ARM sh-sci users hook up HAVE_CLK, the driver can
be switched over to having an outright dependency on it and the
ifdefs can go away.Signed-off-by: Paul Mundt
