All architectures except for sparc64 use the dma-direct code in some
form, and even for sparc64 we had the discussion of a direct mapping
mode a while ago. In preparation for directly calling the direct
mapping code don't bother having it optionally but always build the
code in. This is a minor hardship for some powerpc and arm configs
that don't pull it in yet (although they should in a relase ot two),
and sparc64 which currently doesn't need it at all, but it will
reduce the ifdef mess we'd otherwise need significantly.

These days architectures are mostly out of the business of dealing with
struct scatterlist at all, unless they have architecture specific iommu
drivers. Replace the ARCH_HAS_SG_CHAIN symbol with a ARCH_NO_SG_CHAIN
one only enabled for architectures with horrible legacy iommu drivers
like alpha and parisc, and conditionally for arm which wants to keep it
disable for legacy platforms.

The arm64 codebase to implement coherent dma allocation for architectures
with non-coherent DMA is a good start for a generic implementation, given
that is uses the generic remap helpers, provides the atomic pool for
allocations that can't sleep and still is realtively simple and well
tested. Move it to kernel/dma and allow architectures to opt into it
using a config symbol. Architectures just need to provide a new
arch_dma_prep_coherent helper to writeback an invalidate the caches
for any memory that gets remapped for uncached access.

The dma remap code only makes sense for not cache coherent architectures
(or possibly the corner case of highmem CMA allocations) and currently
is only used by arm, arm64, csky and xtensa. Split it out into a
separate file with a separate Kconfig symbol, which gets the right
copyright notice given that this code was written by Laura Abbott
working for Code Aurora at that point.

When merging support for SSBD and the CRC32 instructions, the conflict
resolution for the new capability entries in arm64_features[]
inadvertedly predicated the availability of the CRC32 instructions on
CONFIG_ARM64_SSBD, despite the functionality being entirely unrelated.
Move the #ifdef CONFIG_ARM64_SSBD down so that it only covers the SSBD
capability.

The new memory EFI reservation feature we introduced to allow memory
reservations to persist across kexec may trigger an unbounded number
of calls to memblock_reserve(). The memblock subsystem can deal with
this fine, but not before memblock resizing is enabled, which we can
only do after paging_init(), when the memory we reallocate the array
into is actually mapped.
So break out the memreserve table processing into a separate routine
and call it after paging_init() on arm64. On ARM, because of limited
reviewing bandwidth of the maintainer, we cannot currently fix this,
so instead, disable the EFI persistent memreserve entirely on ARM so
we can fix it later.

Bhupesh reports that having numerous memblock reservations at early
boot may result in the following crash:
Unable to handle kernel paging request at virtual address ffff80003ffe0000
...
Call trace:
__memcpy+0x110/0x180

This is caused by the fact that we permit memblock resizing before the
linear mapping is up, and so the memblock_reserved() array is moved
into memory that is not mapped yet.
So let's ensure that this crash can no longer occur, by deferring to
call to memblock_allow_resize() to after the linear mapping has been
created.

On arm64, there is no need to add 2 bytes of padding to the start of
each network buffer just to make the IP header appear 32-bit aligned.
Since this might actually adversely affect DMA performance some
platforms, let's override NET_IP_ALIGN to 0 to get rid of this
padding.

After 'a66649dab350 arm64: fix vdso-offsets.h dependency' if
one will try to build .i file in case of external kernel module,
build fails complaining that prepare0 target is missing. This
issue came up with SystemTap when it tries to build variety
of .i files for its own generated kernel modules trying to
figure given kernel features/capabilities.
The issue is that prepare0 is defined in top level Makefile
only if KBUILD_EXTMOD is not defined. .i file rule depends
on prepare and in case KBUILD_EXTMOD defined top level Makefile
contains empty rule for prepare. But after mentioned commit
arch/arm64/Makefile would introduce dependency on prepare0
through its own prepare target.
Fix it to put proper ifdef KBUILD_EXTMOD around code introduced
by mentioned commit. It matches what top level Makefile does.

Pull stackleak gcc plugin from Kees Cook:
"Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
was ported from grsecurity by Alexander Popov. It provides efficient
stack content poisoning at syscall exit. This creates a defense
against at least two classes of flaws:
- Uninitialized stack usage. (We continue to work on improving the
compiler to do this in other ways: e.g. unconditional zero init was
proposed to GCC and Clang, and more plugin work has started too).
- Stack content exposure. By greatly reducing the lifetime of valid
stack contents, exposures via either direct read bugs or unknown
cache side-channels become much more difficult to exploit. This
complements the existing buddy and heap poisoning options, but
provides the coverage for stacks.
The x86 hooks are included in this series (which have been reviewed by
Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
been merged through the arm64 tree (written by Laura Abbott and
reviewed by Mark Rutland and Will Deacon).

When a memblock allocation APIs are called with align = 0, the alignment
is implicitly set to SMP_CACHE_BYTES.
Implicit alignment is done deep in the memblock allocator and it can
come as a surprise. Not that such an alignment would be wrong even
when used incorrectly but it is better to be explicit for the sake of
clarity and the prinicple of the least surprise.
Replace all such uses of memblock APIs with the 'align' parameter
explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment
in the memblock internal allocation functions.
For the case when memblock APIs are used via helper functions, e.g. like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where
appropriate.
The direct memblock APIs users were updated using the semantic patch below:

Prefer _THIS_IP_ defined in linux/kernel.h.

a few archs had inline assembly instead.
This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

Pull ARM SoC platform updates from Arnd Bergmann:
"A couple of platforms change hands in the MAINTAINERS file:
- Linus Walleij lists himself for the ARM Reference platforms:
versatile, vexpress, integrator and realview. He has been the main
contributor for these for a while, and makes it official now.
- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim
Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the
Actions Semi machines
- Nicolas Ferre lists updates the MAINTAINER listing for the AT91
platform: Ludovic Desroches is now a co-maintainer for the
platform, and several other people (Claudiu Beznea, Cristian
Birsan, Eugen Hristev, Codrin Ciubotariu) take over individual
device drivers.
Thanks everyone for working on this, and welcome to the new
maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time
it's the i.MX 6ULZ 32-bit single-core version.
On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is
used on the reference board for the CIP Super Long Term Support (SLTS)
Linux Kernels"

Pull ARM SoC driver updates from Arnd Bergmann:
"The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.
- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem" device
driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates from Arnd Bergmann:
"There are close to 800 indivudal changesets in this branch again,
which feels like a lot. There are particularly many changes for the
NVIDIA Tegra platform this time, in fact more than it has seen in the
two years since the v4.9 merge window. Aside from this, it's been
fairly normal, with lots of changes going into Renesas R-CAR, NXP
i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.
Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:
Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5
Clearfog is a nice little board for quad-core Marvell Armada 8040
network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
BMC.
NXP i.MX usually sees a lot of new boards each release. This time
there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
same SoM design as the ConnectCore 6UL SBC Express added later.
However, there is a new chip, the i.MX6ULZ, which is an even smaller
variant of the i.MX6ULL, with features removed. There is also support
for the reference board design, the i.MX6ULZ 14x14 EVK.
A new Raspberry Pi variant gets added, this one is the CM3 compute
module based on bcm2837, it was launched in early 2017 but only now
added to the kernel, both as 32-bit and as 64-bit files, as we tend to
do for Raspberry Pi.
On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time are:
- Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
- Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
- Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
- Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana Pi
M2+ H3, with the same board layout.
Similarly, for Rockchips, get get another variant of the 32-bit Asus
Tinker board, the model 'S' based on rk3288, and three now boards
based on the popular RK3399 chip:
- ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
- Rock960: https://www.96boards.org/product/rock960/
- RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and the
RK3399 is the same chip used in several Chromebooks. Finally, we get
support for the PX30 (aka rk3326) chip, which is based on the low-end
64-bit Cortex-A35 CPU core. So far, only the evaluation board is
supported.
One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
based on the MT7622 WiFi router platform, and the first product I've
seen with a 64-bit Mediatek chip in that market:
http://www.banana-pi.org/r64.html
For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.
Amlogic gets initial support for the Meson-G12A chip (S905D2), another
quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
side, we gain support for an actual end-user product, the Endless
Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/
Qualcomm adds support for their MSM8998 SoC and evaluation platform.
This chip is commonly known as the Snapdragon 835, and is used in
high-end phones as well as low-end laptops.
For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the
previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
M3NULCB Starter Kit Pro.
While we have lots of DT changes for NVIDIA to update the existing
files, the only board that gets added is the Toradex Colibri T20 on
Colibri Evaluation Board for the old Tegra2.
Synaptics add support for their AS370 SoC, which is part of the
(formerly Marvell) Berlin line of set-top-box chips used e.g. in the
various Google Chromecast. Only the .dtsi gets added at this point, no
actual machines"
