There are 16 individual channels (NUM_DBDMA_CHANS) to save/restore plus the
global ddma block config (the +1). The last register in a channel can be
skipped since it's read-only (at offset 0x18).

The definition of the irq_ipi structure has two initializations of the
flags field. This combines them.
[Ralf: The issue was originally introduced by commit
be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp.
033890b084adfa367c544864451d7730552ce8bf (kernel.org). The original
intention of the code was to initialize .flags with both flags ored together.
The broken C code as actually implemented will be compiled by an equally
broken gcc to use only the last initialization, that is IRQF_PERCPU
which means this turned into an SMTC bug for 2.6.23 and newer.]
The semantic match that finds this problem is as follows:

Implement page mapping percpu first chunk allocator as a fallback to
the embedding allocator. The next patch will make the embedding
allocator check distances between units to determine whether it fits
within the vmalloc area so that this fallback can be used on such
cases.
sparc64 currently has relatively small vmalloc area which makes it
impossible to create any dynamic chunks on certain configurations
leading to percpu allocation failures. This and the next patch should
allow those configurations to keep working until proper solution is
found.
While at it, mark pcpu_cpu_distance() with __init.

Back in January 2008 Nick Piggin implemented "ticket" spinlocks
for X86 (See commit 314cdbefd1fd0a7acf3780e9628465b77ea6a836).
IA64 implementation has a couple of differences because of the
available atomic operations ... e.g. we have no fetchadd2 instruction
that operates on a 16-bit quantity so we make ticket locks use
a 32-bit word for each of the current ticket and now-serving values.
Performance on uncontended locks is about 8% worse than the previous
implementation, but this seems a good trade for determinism in the
contended case. Performance impact on macro-level benchmarks is in
the noise.
