This Kconfig option was removed during v4.19 development in commit
771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely
and for good") so there's no point to keep it in defconfigs any longer.
FWIW defconfigs were patched with:
--------------------------->8----------------------
find . -name *_defconfig -exec sed -i '/CONFIG_ENABLE_WARN_DEPRECATED/d' {} \;
--------------------------->8----------------------

Pull driver core updates from Greg KH:
"Here is the big driver core patchset for 5.1-rc1
More patches than "normal" here this merge window, due to some work in
the driver core by Alexander Duyck to rework the async probe
functionality to work better for a number of devices, and independant
work from Rafael for the device link functionality to make it work
"correctly".
Also in here is:
- lots of BUS_ATTR() removals, the macro is about to go away
- firmware test fixups
- ihex fixups and simplification
- component additions (also includes i915 patches)
- lots of minor coding style fixups and cleanups.
All of these have been in linux-next for a while with no reported
issues"

Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver patch pull request for 5.1-rc1.
The largest thing by far is the new habanalabs driver for their AI
accelerator chip. For now it is in the drivers/misc directory but will
probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they
asked me to do as the MEI driver is starting to interact with the i915
driver, and it needed some coordination. All of those patches have
been properly acked by the relevant subsystem maintainers.
All of these have been in linux-next with no reported issues, most for
quite some time"

Pull ARM new SoC family support from Arnd Bergmann:
"Two new SoC families are added this time.
Sugaya Taichi submitted support for the Milbeaut SoC family from
Socionext and explains:
"SC2000 is a SoC of the Milbeaut series. equipped with a DSP
optimized for computer vision. It also features advanced
functionalities such as 360-degree, real-time spherical stitching
with multi cameras, image stabilization for without mechanical
gimbals, and rolling shutter correction. More detail is below:
https://www.socionext.com/en/products/assp/milbeaut/SC2000.html"
Interestingly, this one has a history dating back to older chips made
by Socionext and previously Matsushita/Panasonic based on their own
mn10300 CPU architecture that was removed from the kernel last year.
Manivannan Sadhasivam adds support for another SoC family, this is the
Bitmain BM1880 chip used in the Sophon Edge TPU developer board.
The chip is intended for Deep Learning applications, and comes with
dual-core Arm Cortex-A53 to run Linux as well as a RISC-V
microcontroller core to control the tensor unit. For the moment, the
TPU is not accessible in mainline Linux, so we treat it as a generic
Arm SoC.

These are actual commercial products we now support with an in-kernel
device tree source file:
- Bosch Guardian is a product made by Bosch Power Tools GmbH, based
on the Texas Instruments AM335x chip
- Winterland IceBoard is a Texas Instruments AM3874 based machine
used in telescopes at the south pole and elsewhere, see commit
d031773169df2 for some pointers:
- Inspur on5263m5 is an x86 server platform with an Aspeed ast2500
baseboard management controller. This is for running on the BMC.
- Zodiac Digital Tapping Unit, apparently a kind of ethernet switch
used in airplanes.
- Phicomm K3 is a WiFi router based on Broadcom bcm47094
- Methode Electronics uDPU FTTdp distribution point unit
- X96 Max, a generic TV box based on Amlogic G12a (S905X2)
- NVIDIA Shield TV (Darcy) based on Tegra210
And then there are several new SBC, evaluation, development or modular
systems that we add:
- Three new Rockchips rk3399 based boards:

- MYIR Tech MYD-LPC4357 development based on the NXP lpc4357
microcontroller
- Chameleon96, an Intel/Altera Cyclone5 based FPGA development system
in 96boards form factor
- Arm Fixed Virtual Platforms(FVP) Base RevC, a purely virtual
platform for corresponding to the latest "fast model"
- Another Raspberry Pi variant: Model 3 A+, supported both in 32-bit
and 64-bit mode.
- Oxalis Evalkit V100 based on NXP Layerscape LS1012a, in 96Boards

include updates for
- STMicroelectronics stm32mp1, which was now formally launched last
week
- Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
- Action Semi S700
- TI AM654x, their recently merged 64-bit SoC from the OMAP family

Pull ARM SoC platform updates from Arnd Bergmann:
"The APM X-Gene platform is now maintained by folks from Ampere
computing that took over the product line a while ago, this gets
reflected in the MAINTAINERS file.
Cleanups continue on the older mach-davinci and mach-pxa platform, to
get them to be more like the modern ones. For pxa, we now remove the
Raumfeld platform code as it now works with device tree based booting.
i.MX adds a couple new features for the i.MX7ULP SoC
Mediatek gains support for a new SoC: MT7629 is a new wireless router
platform, following MT7623.
Aside from those, there are the usual minor cleanups and bugfixes

Pull locking updates from Ingo Molnar:
"The biggest part of this tree is the new auto-generated atomics API
wrappers by Mark Rutland.
The primary motivation was to allow instrumentation without uglifying
the primary source code.
The linecount increase comes from adding the auto-generated files to
the Git space as well:
include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++--
include/asm-generic/atomic-long.h | 1174 ++++++++++---
include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++
include/linux/atomic.h | 1241 +------------
I preferred this approach, so that the full call stack of the (already
complex) locking APIs is still fully visible in 'git grep'.
But if this is excessive we could certainly hide them.
There's a separate build-time mechanism to determine whether the
headers are out of date (they should never be stale if we do our job
right).
Anyway, nothing from this should be visible to regular kernel
developers.
Other changes:
- Add support for dynamic keys, which removes a source of false
positives in the workqueue code, among other things (Bart Van
Assche)
- Updates to tools/memory-model (Andrea Parri, Paul E. McKenney)

THP pages can get split during different code paths. An incremented
reference count does imply we will not split the compound page. But the
pmd entry can be converted to level 4 pte entries. Keep the code
simpler by allowing large IOMMU page size only if the guest ram is
backed by hugetlb pages.

mm_iommu_do_alloc
The current code doesn't do page migration if the page allocated is a
compound page. With HugeTLB migration support, we can end up allocating
hugetlb pages from CMA region. Also, THP pages can be allocated from
CMA region. This patch updates the code to handle compound pages
correctly. The patch also switches to a single get_user_pages with the
right count, instead of doing one get_user_pages per page. That avoids
reading page table multiple times. This is done by using
get_user_pages_longterm, because that also takes care of DAX backed
pages.
DAX pages lifetime is dictated by file system rules and as such, we need
to make sure that we free these pages on operations like truncate and
punch hole. If we have long term pin on these pages, which are mostly
return to userspace with elevated page count, the entity holding the
long term pin may not be aware of the fact that file got truncated and
the file system blocks possibly got reused. That can result in
corruption.
The patch also converts the hpas member of mm_iommu_table_group_mem_t to
a union. We use the same storage location to store pointers to struct
page. We cannot update all the code path use struct page *, because we
access hpas in real mode and we can't do that struct page * to pfn
conversion in real mode.

In the old days, remap_pfn_range() required pages to be marked as
PG_reserved, so they would e.g. never get swapped out. This was
required for special mappings. Nowadays, this is fully handled via the
VMA (VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP inside
remap_pfn_range() to be precise). PG_reserved is no longer required but
only a relic from the past.
So only architecture specific MM handling might require it (e.g. to
detect them as MMIO pages). As there are no architecture specific
checks for PageReserved() apart from MCA handling in ia64code, this can
go. Use simple vzalloc()/vfree() instead.
Note that before calling vzalloc(), size has already been aligned to
PAGE_SIZE, no need to align again.

The crashkernel is reserved via memblock_reserve(). memblock_free_all()
will call free_low_memory_core_early(), which will go over all reserved
memblocks, marking the pages as PG_reserved.
So manually marking pages as PG_reserved is not necessary, they are
already in the desired state (otherwise they would have been handed over
to the buddy as free pages and bad things would happen).
