While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

compiling issue
"entry.h" needs 'asmlinkage', and "asm/linkage.h" does not provide it.
So need include "linux/linkage.h" to use generic one instead of.
The related error (with allmodconfig under microblaze):
CC [M] drivers/net/ethernet/emulex/benet/be_main.o

Fix sparse warning by declaration do_notify_resume function
called from entry.S.
Warning:
arch/microblaze/kernel/signal.c:357:6: warning: symbol
'do_notify_resume' was not declared. Should it be static?

r0_ram pool was used for saving/restoring register
content if hw exception happen. This poll was replaced by
pt_pool_space with PT_SIZE size.
Based on this change SAVE_STATE_ARG_SPACE was removed which
caused that PTO offset is zero that's why is also removed.
r0_ram space was used as scratchpad by v850. In early
Microblaze Linux developing phase was this part of code
blindly copied.

Now that the return from alloc_percpu is compatible with the address
of per-cpu vars, it makes sense to hand around the address of per-cpu
variables. To make this sane, we remove the per_cpu__ prefix we used
created to stop people accidentally using these vars directly.
Now we have sparse, we can use that (next patch).
tj: * Updated to convert stuff which were missed by or added after the
original patch.
* Kill per_cpu_var() macro.
