David S. Miller daecbf58a5 sparc64: Use a seperate counter for timer interrupts and NMI checks, like x86.
This keeps us from having to use kstat_irqs_cpu() from the NMI handler,
the former of which is a profiled function.

Instead we use a currently empty slot in the cpu_data

David S. Miller 19f0fa3fb3 sparc64: Move trap_block[] definitions into a new header file.
Later we're going to want to get at these definitions from
asm/percpu.h and that's not possible via cpudata.h because
of the set of dependencies the non-trap_block[] stuff has.

David S. Miller 557fe0e884 sparc64: Reclaim trap_block[]->hdesc
This really isn't necessary at all, a local variable suits the
job just fine.

This frees up 8 bytes in the trap_block[] that we can use later
to store the per-cpu base addresses.

David S. Miller ba4962d7a6 sparc64: Clean up CPU chip type probing code.
Three main things:

1) Make prober an arch initcall instead of using hard-coded invocation
   from paging_init()

2) Shrink table size, the fpu ident stuff was never used.

3) Use named struct initialized in table.

Sam Ravnborg a439fe51a1 sparc, sparc64: use arch/sparc/include
The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
