That's HAVE_PERF_COUNTERS not HAVE_PERF_COUNTER. This was right

commit dbe6f1869188b6e04e38aa861dd198befb08bcd7
("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.

The end brace for a larger for statement was placed inside the #else
part of #ifdef TIMER_VECT1. However, for all current chips, the
define TIMER_VECT1 is always unset, and the error was never triggered.
Move the brace down below the #endif.

The code didn't test the pointer to the newly allocated
memory, but a parameter sent in as value.
Since the input parameter was most often set, the code
would have used a null pointer if the kmalloc failed.
If the input parameter was not set, the code would
leak the allocated buffer.

Somehow, the assignments of rw->lock got written as comparisons.
The effect probably was that the read-write spinlocks never locked.
However, since the locks are only used in CONFIG_SMP and SMP CRIS is
experimental, it has never been identified as a problem.

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.

Many aspects of the Blackfin memory map is exactly the same across all
variants. Rather than copy and paste all of these duplicated values in
each header, unify all of these into the common Blackfin memory map header
file. In the process, push down BF561 SMP specific stuff to the BF561
specific header to keep the noise down.

Rather than use "Linux" in the boot image name (as this is redundant --
the image type is already set to "linux"), use the CPU name. This makes
it fairly obvious when a wrong image is accidentally booted. Otherwise
there is no kernel output and you waste time scratching your head
wondering wtf just happened.

The current cache options don't really represent the hardware features.
They end up setting different aspects of the hardware so that the end
result is to turn on/off the cache. Unfortunately, when we hit cache
problems with the hardware, it's difficult to test different settings to
root cause the problem. The current settings also don't cleanly allow for
different caching behaviors with different regions of memory.
So split the configure options such that they properly reflect the settings
that are applied to the hardware.

We read the SWRST (Software Reset) register to get at the last reset
state, and then we may configure the DOUBLE_FAULT bit to control behavior
when a double fault occurs. But if the lower bits of the register is
already set (like UART boot mode on a BF54x), we inadvertently make the
system reset by writing to the SYSTEM_RESET field at the same time. So
make sure the lower 4 bits are always cleared.

With the common IRQ code initializing much more of the irq_desc state, we
can't blindly initialize it ourselves to the local bad_irq state. If we
do, we end up wrongly clobbering many fields. So punt most of the bad irq
code as the common layers will handle the default state, and simply call
handle_bad_irq() directly when the IRQ we are processing is invalid.

The patch adds kernel parameter intel_iommu=pt to set up pass through
mode in context mapping entry. This disables DMAR in linux kernel; but
KVM still runs on VT-d and interrupt remapping still works.
In this mode, kernel uses swiotlb for DMA API functions but other VT-d
functionalities are enabled for KVM. KVM always uses multi level
translation page table in VT-d. By default, pass though mode is disabled
in kernel.
This is useful when people don't want to enable VT-d DMAR in kernel but
still want to use KVM and interrupt remapping for reasons like DMAR
performance concern or debug purpose.
