frv, h8300, m68k, microblaze, openrisc, score, um and xtensa currently
do not register a CPU device. Add the config option GENERIC_CPU_DEVICES
which causes a generic CPU device to be registered for each present CPU,
and make all these architectures select it.Richard Weinberger covered UML and suggested using
per_cpu.Signed-off-by: Ben Hutchings

microblaze copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in. Since that's in
a separate file now, we can reuse the common implementation.The only difference is handling of nocache flag,
that turns out to be done correctly by the
generic code since arch/microblaze/include/asm/io.h
defines ioremap_nocache same as ioremap.Signed-off-by: Michael S. Tsirkin

This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic
implementation of find_*_bit_le() in lib/find_next_bit.c or not.For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which
enable CONFIG_GENERIC_FIND_NEXT_BIT.But m68knommu wants to define own faster find_next_zero_bit_le() and
continues using generic find_next_{,zero_}bit().

The device tree code is now in two pieces: some which can be used generically
on any platform which selects CONFIG_OF_FLATTREE, and some early which is used
at boot time on only a few architectures. This patch segregates the early
code so that only those architectures which care about it need compile it.
This also means that some of the requirements in the early code (such as
a cmd_line variable) that most architectures (e.g. X86) don't provide
can be ignored.Signed-off-by: Stephen Neuendorffer
[grant.likely@secretlab.ca: remove extra blank line addition]

Kgdb uses brki r16, 0x18 instruction to call
low level _debug_exception function which save
current state to pt_regs and call microblaze_kgdb_break
function. _debug_exception should be called only from
the kernel space. User space calling is not supported
because user application debugging uses different handling.pt_regs_to_gdb_regs loads additional special registers
which can't be changed* Enable KGDB in Kconfig
* Remove ancient not-tested KGDB support
* Remove ancient _debug_exception code from entry.SOnly MMU KGDB support is supported.

Signed-off-by: Grant Likely -
All of the options in drivers/of/Kconfig depend on CONFIG_OF. Putting
all of them inside a menu block simplifies the dependency statements.
It also creates a logical group for adding user selectable OF options.This patch also changes (PPC_OF || MICROBLAZE) statements to (!SPARC)
so that those options are available to other architectures (and in
fact the !SPARC conditions should probably be re-evalutated since the
code is more generic now)This patch also moves the definition of CONFIG_DTC from arch/* to

Remove ancient Kconfig option for consistent code.
MMU uses cache inhibit pages.noMMU uses UNCACHE SHADOW feature where is used double ram size.
For example:
Physical ram is 256MB and cache are setup to cover the same size.
But if you setup in HW that size is 512MB and cache covers 256MB
than you can use adresses from 256-512MB without caches and
correspond with 0-256MB with cache. That's why I am using
dcache base/high addresses to find out uncache area.Signed-off-by: Michal Simek

There are two parts of changes. The first is just enable
PCI in Makefiles and in Kconfig. The second is the rest of
missing files. I didn't want to add it with previous patch
because that patch is too big.Current Microblaze toolchain has problem with weak symbols
that's why is necessary to apply this changes to be possible
to compile pci support.

2. Enable DMA debug option
3. Setup notifierAd 1. dma-mapping come from powerpc and x86 version and it is based on
generic dma-mapping-common.hAd 2. DMA support debug features which is used in generic file.

With dynamic function tracer, by default, _mcount is defined as an
"empty" function, it returns directly without any more action. When
enabling it in user-space, it will jump to a real tracing
function(ftrace_caller), and do the real job for us.Differ from the static function tracer, dynamic function tracer provides
two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the
tracing of some indicated kernel functions(set_ftrace_filter).In the kernel version, there is only one "_mcount" string for every
kernel function, so, we just need to match this one in mcount_regex of
scripts/recordmcount.pl.For more information please look at code and Documentation/trace folder.
Steven ACK that scripts/recordmcount.pl part.
