Use "ceu0" and "ceu1" as CEU names instead of "ceu".
This fixes "memchunk" kernel command line selection
on the solution engine 7724 board.
With this patch applied use "memchunk.ceu0=1m" or
"memchunk.ceu1=1m" on kernel command line to override
physically memory size to one meg for CEU0 or CEU1.

* git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
sh: Fix up HAVE_PERF_COUNTERS typo.
sh: Fix up more dma-mapping fallout.
sh: SH7786 SMP support.
sh: Wire up the uncached fixmap on sh64 as well.
sh: Use local TLB flush in set_pte_phys().
sh: Provide cpu_idle_wait() to fix up cpuidle/SMP build.
That's HAVE_PERF_COUNTERS not HAVE_PERF_COUNTER. This was right
initially but I seem to have screwed it up while re-typing it out
by hand on another machine when I checked it in. Hmph.

commit dbe6f18691
("dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated"
conveniently broke every single SH build.
In the future it would be great if people could at least bother
figuring out how to use grep.

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

set_pte_phys() presently uses the global flush_tlb_one(), which locks on
SMP trying to do the IPI. As we have not even initialized the other CPUs
at this point, switch to the local_ variant so the flush happens on the
boot CPU.

Since dmanr is unsigned, negatives are wrapped and caught by the other test.

The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin
systems. This is because we don't define dma_sync_sg_for_cpu at all, so
until the DMA asm-generic conversion/cleanup is done after the next
release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

We don't support the BF535 at all, and the exception 0x2A text specific to
it is pretty verbose and confusing (since the behavior is simply odd), so
punt it to keep the noise down.
