It isn't used any more by us now that the generic kernel build
offers DEBUG_INFO_REDUCED, so just get rid of it.Signed-off-by: Chris Metcalf

This change adds infrastructure (CONFIG_TILE_HVGLUE_TRACE) that
provides C code wrappers for the calls the kernel makes to the Tilera
hypervisor. This allows standard kernel infrastructure like FTRACE to
be able to instrument hypervisor calls.To allow direct calls to the true API, we export their names with a
leading underscore as well. This is important for the few contexts
where we need to make hypervisor calls without touching the stack.As part of this change, we also switch from creating the symbols
with linker magic to creating them with assembler magic. This lets
us provide a symbol type and generally make them appear more as symbols
and less as just random values in the Elf namespace.Signed-off-by: Chris Metcalf

Several architectures have similar stack debugging config options.
They all pretty much do the same thing, some with slightly
differing help text.This patch changes the architectures to instead enable a Kconfig
boolean, and then use that boolean in the generic Kconfig.debug
to present the actual menu option. This removes a bunch of
duplication and adds consistency across arches.Signed-off-by: Dave Hansen

Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it
to lib/Kconfig.debug so each arch doesn't have to define it. This
obviously makes the option generic, but that's fine because the config is
already used in generic code.It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.Signed-off-by: Stephen Boyd

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar

This change is the core kernel support for TILEPro and TILE64 chips.
No driver support (except the console driver) is included yet.This includes the relevant Linux headers in asm/; the low-level
low-level "Tile architecture" headers in arch/, which are
shared with the hypervisor, etc., and are build-system agnostic;
and the relevant hypervisor headers in hv/.Signed-off-by: Chris Metcalf
