This 'commit 86588296acbf ("fdt: Properly handle "no-map" field in the
memory region")' is keeping the no-map regions in memblock.memory with
MEMBLOCK_NOMAP flag set to use no-map memory for EFI using memblock
api's, but during the initialization sparse_init mark all memblock.memory
as present using for_each_mem_pfn_range, which is creating the memmap for
no-map memblock regions.
Upstream has suggested to make use of bootloader to pass this as not a
memory,but because of possibility that some bootloaders might not support
this and also due to time constraints in evaluating this approach on 5.10,
Use command line parameter as a temporary solution. Get in the appropriate
solution later after further discussion with upstream.
Add kernel param "android12_only.will_be_removed_soon.memblock_nomap_remove"
which when enabled will remove page structs for these regions using memblock_remove.
With this change we will be able to save ~11MB memory for ~612MB carve out.

There maybe an overflow in memblock_overlaps_region() if it is called with
base and size such that
base + size > PHYS_ADDR_MAX
Make sure that memblock_overlaps_region() caps the size to prevent such
overflow and remove now duplicated call to memblock_cap_size() from

commit 79e482e9c3ae86e849c701c846592e72baddda5a upstream.
Commit b10d6bca87 ("arch, drivers: replace for_each_membock() with
for_each_mem_range()") didn't take into account that when there is
movable_node parameter in the kernel command line, for_each_mem_range()
would skip ranges marked with MEMBLOCK_HOTPLUG.
The page table setup code in POWER uses for_each_mem_range() to create
the linear mapping of the physical memory and since the regions marked
as MEMORY_HOTPLUG are skipped, they never make it to the linear map.
A later access to the memory in those ranges will fail:

The physical memory of a system is divided into several types, like
memory reserved for device, for kernel pagetable, etc. The remaining
area is for Buddy allocator. Normally, The memory for Buddy is consist
of different size blocks, so, under meeting the memory request of kernel
booting, we can defer free the large block size to Buddy which can be
done later in work queue in parallel to other kernel threads, and the
size of the large block can be defined in kernel command line
Save boot time about 6ms on 512MB rv1126 evb.

It is useful to know the exact caller of memblock_phys_alloc_range() to
track early memory reservations during development.
Currently, when memblock debugging is enabled, the allocations done with
memblock_phys_alloc_range() are only reported at memblock_reserve():
[ 0.000000] memblock_reserve: [0x000000023fc6b000-0x000000023fc6bfff] memblock_alloc_range_nid+0xc0/0x188
Add memblock_dbg() to memblock_phys_alloc_range() to get details about
its usage.
For example:
[ 0.000000] memblock_phys_alloc_range: 4096 bytes align=0x1000 from=0x0000000000000000 max_addr=0x0000000000000000 early_pgtable_alloc+0x24/0x178
[ 0.000000] memblock_reserve: [0x000000023fc6b000-0x000000023fc6bfff] memblock_alloc_range_nid+0xc0/0x188

[ Upstream commit 2dcb3964544177c51853a210b6ad400de78ef17d ]
With kaslr the kernel image is placed at a random place, so starting the
bottom-up allocation with the kernel_end can result in an allocation
failure and a warning like this one:
hugetlb_cma: reserve 2048 MiB, up to 2048 MiB per node
------------[ cut here ]------------

At the same time, the kernel image is protected with memblock_reserve(),
so we can just start searching at PAGE_SIZE. In this case the bottom-up
allocation has the same chances to success as a top-down allocation, so
there is no reason to fallback in the case of a failure. All together it
simplifies the logic.

On architectures that support the preservation of memblock metadata
after __init, allow drivers to call memblock_free() to free a
reservation made by early arch code. This is a hack to support the
freeing of bootsplash reservations passed to Linux by the bootloader.
(This should be reworked in future versions of Android; do not
cherry-pick this patch forward.)

chanseset b3a7bb1851c8 ("docs: get rid of :c:type explicit declarations for structs")
removed several :c:type: markups, except by one.
Now, Sphinx 3.x complains about it:

The :c:type:`foo` only works properly with structs before
Sphinx 3.x.
On Sphinx 3.x, structs should now be declared using the
.. c:struct, and referenced via :c:struct tag.
As we now have the automarkup.py macro, that automatically
convert:
struct foo
into cross-references, let's get rid of that, solving
several warnings when building docs with Sphinx 3.x.

Use __for_each_mem_range() and, essentially, __next_mem_region() with

start_pfn = memblock_region_memory_base_pfn(reg);
end_pfn = memblock_region_memory_end_pfn(reg);
/* do something with start_pfn and end_pfn */
}
Rather than iterate over all memblock.memory regions and each time query
for their start and end PFNs, use for_each_mem_pfn_range() iterator to get
simpler and clearer code.

"physmem" in the memblock allocator is somewhat weird: it's not actually
used for allocation, it's simply information collected during boot, which
describes the unmodified physical memory map at boot time, without any
standby/hotplugged memory. It's only used on s390 and is currently the
only reason s390 keeps using CONFIG_ARCH_KEEP_MEMBLOCK.
Physmem isn't numa aware and current users don't specify any flags. Let's
hide it from the user, exposing only for_each_physmem(), and simplify. The
interface for physmem is now really minimalistic:
- memblock_physmem_add() to add ranges
- for_each_physmem() / __next_physmem_range() to walk physmem ranges
Don't place it into an __init section and don't discard it without
CONFIG_ARCH_KEEP_MEMBLOCK. As we're reusing __next_mem_range(), remove
the __meminit notifier to avoid section mismatch warnings once
CONFIG_ARCH_KEEP_MEMBLOCK is no longer used with
CONFIG_HAVE_MEMBLOCK_PHYS_MAP.
While fixing up the documentation, sneak in some related cleanups. We can
stop setting CONFIG_ARCH_KEEP_MEMBLOCK for s390 next.

CONFIG_HAVE_MEMBLOCK_NODE_MAP is used to differentiate initialization of
nodes and zones structures between the systems that have region to node
mapping in memblock and those that don't.
Currently all the NUMA architectures enable this option and for the
non-NUMA systems we can presume that all the memory belongs to node 0 and
therefore the compile time configuration option is not required.
The remaining few architectures that use DISCONTIGMEM without NUMA are
easily updated to use memblock_add_node() instead of memblock_add() and
thus have proper correspondence of memblock regions to NUMA nodes.
Still, free_area_init_node() must have a backward compatible version
because its semantics with and without CONFIG_HAVE_MEMBLOCK_NODE_MAP is
different. Once all the architectures will use the new semantics, the
entire compatibility layer can be dropped.
To avoid addition of extra run time memory to store node id for
architectures that keep memblock but have only a single node, the node id
field of the memblock_region is guarded by CONFIG_NEED_MULTIPLE_NODES and
the corresponding accessors presume that in those cases it is always 0.

Patch series "mm: rework free_area_init*() funcitons".
After the discussion [1] about removal of CONFIG_NODES_SPAN_OTHER_NODES
and CONFIG_HAVE_MEMBLOCK_NODE_MAP options, I took it a bit further and
updated the node/zone initialization.
Since all architectures have memblock, it is possible to use only the
newer version of free_area_init_node() that calculates the zone and node
boundaries based on memblock node mapping and architectural limits on
possible zone PFNs.
The architectures that still determined zone and hole sizes can be
switched to the generic code and the old code that took those zone and
hole sizes can be simply removed.
And, since it all started from the removal of
CONFIG_NODES_SPAN_OTHER_NODES, the memmap_init() is now updated to iterate

This patch (of 21):
There are several places in the code that directly dereference
memblock_region.nid despite this field being defined only when
CONFIG_HAVE_MEMBLOCK_NODE_MAP=y.
Replace these with calls to memblock_get_region_nid() to improve code
robustness and to avoid possible breakage when
CONFIG_HAVE_MEMBLOCK_NODE_MAP will be removed.

I've noticed that there is no interface exposed by CMA which would let
me to declare contigous memory on particular NUMA node.
This patchset adds the ability to try to allocate contiguous memory on a
specific node. It will fallback to other nodes if the specified one
doesn't work.
Implement a new method for declaring contigous memory on particular node
and keep cma_declare_contiguous() as a wrapper.

On the s390 platform memblock.physmem array is being built by directly
calling into memblock_add_range() which is a low level function not
intended to be used outside of memblock. Hence lets conditionally add
helper functions for physmem array when HAVE_MEMBLOCK_PHYS_MAP is
enabled. Also use MAX_NUMNODES instead of 0 as node ID similar to
memblock_add() and memblock_reserve(). Make memblock_add_range() a
static function as it is no longer getting used outside of memblock.

sparse_buffer_init() use memblock_alloc_try_nid_raw() to allocate memory
for page management structure, if memory allocation fails from specified
node, it will fall back to allocate from other nodes.
Normally, the page management structure will not exceed 2% of the total
memory, but a large continuous block of allocation is needed. In most
cases, memory allocation from the specified node will succeed, but a
node memory become highly fragmented will fail. we expect to allocate
memory base section rather than by allocating a large block of memory
from other NUMA nodes
Add memblock_alloc_exact_nid_raw() for this situation, which allocate
boot memory block on the exact node. If a large contiguous block memory
allocate fail in sparse_buffer_init(), it will fall back to allocate
small block memory base section.

Until commit 92d12f9544 ("memblock: refactor internal allocation
functions") the maximal address for memblock allocations was forced to
memblock.current_limit only for the allocation functions returning
virtual address. The changes introduced by that commit moved the limit
enforcement into the allocation core and as a result the allocation
functions returning physical address also started to limit allocations
to memblock.current_limit.
This caused breakage of etnaviv GPU driver:
etnaviv etnaviv: bound 130000.gpu (ops gpu_ops)
etnaviv etnaviv: bound 134000.gpu (ops gpu_ops)

Most architectures do not need the memblock memory after the page
allocator is initialized, but only few enable ARCH_DISCARD_MEMBLOCK in the
arch Kconfig.
Replacing ARCH_DISCARD_MEMBLOCK with ARCH_KEEP_MEMBLOCK and inverting the
logic makes it clear which architectures actually use memblock after
system initialization and skips the necessity to add ARCH_DISCARD_MEMBLOCK
to the architectures that are still missing that option.

Introduce a new iterator for_each_free_mem_pfn_range_in_zone.
This iterator will take care of making sure a given memory range provided
is in fact contained within a zone. It takes are of all the bounds
checking we were doing in deferred_grow_zone, and deferred_init_memmap.
In addition it should help to speed up the search a bit by iterating until
the end of a range is greater than the start of the zone pfn range, and
will exit completely if the start is beyond the end of the zone.
