Currently all architectures but microblaze unconditionally define
USE_ELF_CORE_DUMP. The microblaze omission seems like an error to me, so
let's kill this ifdef and make sure we are the same everywhere.

The next commit will require the use of MODULE_SYMBOL_PREFIX in
.tmp_exports-asm.S. Currently it is mixed in with C structure
definitions in "asm/module.h". Move the definition of this arch option
into Kconfig, so it can be easily accessed by any code.
This also lets modpost.c use the same definition. Previously modpost
relied on a hardcoded list of architectures in mk_elfconfig.c.
A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs,
showed the generated code was unchanged. vmlinux was identical save
for build ids, and an apparently randomized suffix on a single "__key"
symbol in the kallsyms data).

Normally there is no user-reserved memory after the DMA region which means
there is no user-reserved ICPLB coverage. So the DMA hole can be covered
by the large hole that is always added to cover up to the async bank. We
only need an explicit DMA whole when we also add an explicit mapping for
the user-reserved memory.

The error masks are only needed in the BF537 demux error code, so instead
of needing all the short peripheral defines in global space, push these
masks into the one file where they are actually needed. This fixes a
bunch of define collisions with common code (can/serial/etc...).

When testing PREEMPT_RT kernel on BF561-EZKit, the kernel blocks while
booting. When the kernel initializes the ethernet driver, it sleeps and
never wakes up.
The issue happens when the kernel waits for a timer for Core B to timeout
(the timers are per-cpu based: static DEFINE_PER_CPU(struct tvec_base *,
tvec_bases) = &boot_tvec_bases).
However, the ksoftirqd thread for Core B (note, the ksoftirqd thread is
also per-cpu based) cannot work properly, and the timers for Core B never
times out.
When ksoftirqd() for the first time runs on core B, it is possible core A
is still initializing core B (see smp_init() -> cpu_up() -> __cpu_up()).
So the "cpu_is_offline()" check may return true and ksoftirqd moves to
"wait_to_die".
So delay the core b start up until the per-cpu timers have been set up
fully.

While fetching instructions at the boundary of L1 instruction SRAM, a false
External Memory Addressing Error might be triggered. We should ignore this
and continue on our way to avoid random crashes.
Because hardware errors are not exact in the Blackfin architecture, we need
to catch a few more common cases when the code flow changes and the signal
is finally delivered.

The point of this small chunk was to avoid anomaly 05000310. This never
really seemed to do what it was intended though -- no valid CPLBs exist
over the reserved memory, and there is often memory before it anyways (due
to the uClinux MTD and/or reserved DMA region). Plus, it doesn't address
the L1 instruction case.
So drop this chunk as it wastes memory and is affront to humanity.

While we're moving the BF54x code, have the BF54xM variants select the
normal BF54x values so that the rest of the Kconfig tree doesn't need to
check the BF54xM variant everytime it wants to check the BF54x.

If we're double faulting, then we have to assume the VMAs are not safe as
broken pointers here will prevent full trace output for the double fault.
Shouldn't be a big problem though as rarely is a double fault caused by
code in userspace.
