Stephen Rothwell f8d91faff3 of/sparc: remove include of linux/of_platform.h from asm/of_platform.h
Now that we have removed all inclusions of asm/of_platform.h, this
compatability include can be removed.

David S. Miller 6717c282e4 sparc: Add __KERNEL__ ifdef protection to pt_regs helpers.
Some of them use 'bool' and whatnot and therefore are not
kosher for userspace, so don't export them there.

Reported by Roland McGrath.

David S. Miller 09ee167cbf sparc64: Hook up trigger_all_cpu_backtrace().
We already have code that does this, but it is only currently attached
to sysrq-'y'.

David S. Miller 5afe27380b sparc64: Make global reg dumping even more useful.
Record one more level of stack frame program counter.

Particularly when lockdep and all sorts of spinlock debugging is
enabled, figuring out the caller of spin_lock() is difficult when the
cpu is stuck on the lock.

Mikael Pettersson d72609e17f sparc64: FUTEX_OP_ANDN fix
Correct sparc64's implementation of FUTEX_OP_ANDN to do a
bitwise negate of the oparg parameter before applying the
AND operation. All other archs that support FUTEX_OP_ANDN
either negate oparg explicitly (frv, ia64, mips, sh, x86),
or do so indirectly by using an and-not instruction (powerpc).
Since sparc64 has and-not, I chose to use that solution.

I've not found any use of FUTEX_OP_ANDN in glibc so the
impact of this bug is probably minor. But other user-space
components may try to use it so it should still get fixed.

I forgot to delete this when I removed the ISA bus layer
from the sparc ports.

Roland McGrath e35a8925e0 sparc64: tracehook: TIF_NOTIFY_RESUME
This adds TIF_NOTIFY_RESUME support for sparc64.
When set, we call tracehook_notify_resume() on the way to user mode.

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.
