dma-mapping: fix page attributes for dma_mmap_*
All the way back to introducing dma_common_mmap we've defaulted to mark
the pages as uncached. But this is wrong for DMA coherent devices.
Later on DMA_ATTR_WRITE_COMBINE also got incorrect treatment as that
flag is only treated special on the alloc side for non-coherent devices.
Introduce a new dma_pgprot helper that deals with the check for coherent
devices so that only the remapping cases ever reach arch_dma_mmap_pgprot
and we thus ensure no aliasing of page attributes happens, which makes
the powerpc version of arch_dma_mmap_pgprot obsolete and simplifies the
remaining ones.
Note that this means arch_dma_mmap_pgprot is a bit misnamed now, but
we'll phase it out soon.

KVM: arm: Don't write junk to CP15 registers on reset
At the moment, the way we reset CP15 registers is mildly insane: We write junk to them, call the reset functions, and then check that we have something else in them. The "fun" thing is that this can happen while the guest is running (PSCI, for example). If anything in KVM has to evaluate the state of a CP15 register while junk is in there, bad thing may happen. Let's stop doing that. Instead, we track that we have called a reset function for that register, and assume that the reset function has done something. In the end, the very need of this reset check is pretty dubious, as it doesn't check everything (a lot of the CP15 reg leave outside of the cp15_regs[] array). It may well be axed in the near future.

add swiotlb support to arm
This fixes a cascade of regressions that originally started with
the addition of the ia64 port, but only got fatal once we removed
most uses of block layer bounce buffering in Linux 4.18.
The reason is that while the original i386/PAE code that was the first
architecture that supported > 4GB of memory without an iommu decided to
leave bounce buffering to the subsystems, which in those days just mean
block and networking as no one else consumer arbitrary userspace memory.
Later with ia64, x86_64 and other ports we assumed that either an iommu
or something that fakes it up ("software IOTLB" in beautiful Intel
speak) is present and that subsystems can rely on that for dealing with
addressing limitations in devices. Except that the ARM LPAE scheme
that added larger physical address to 32-bit ARM did not follow that
scheme and thus only worked by chance and only for block and networking
I/O directly to highmem.
Long story, short fix - add swiotlb support to arm when build for LPAE
platforms, which actuallys turns out to be pretty trivial with the
modern dma-direct / swiotlb code to fix the Linux 4.18-ish regression.

ARM: Device-tree updates
We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM Mali
GPU devices added to device trees, since the DRM drivers have now been
merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Polish and fixes for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now at
feature parity with TX1

ARM: SoC platform updates
SoC platform changes. Main theme this merge window:
- The Netx platform (Netx 100/500) platform is removed by Linus Walleij--
the SoC doesn't have active maintainers with hardware, and in
discussions with the vendor the agreement was that it's OK to remove.
- Russell King has a series of patches that cleans up and refactors
SA1101 and RiscPC support.

mm, kprobes: generalize and rename notify_page_fault() as kprobe_page_fault()
Architectures which support kprobes have very similar boilerplate around
calling kprobe_fault_handler(). Use a helper function in kprobes.h to
unify them, based on the x86 code.
This changes the behaviour for other architectures when preemption is
enabled. Previously, they would have disabled preemption while calling
the kprobe handler. However, preemption would be disabled if this fault
was due to a kprobe, so we know the fault was not due to a kprobe
handler and can simply return failure.
This behaviour was introduced in commit

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

arm: switch to generic version of pte allocation
Replace __get_free_page() and alloc_pages() calls with the generic __pte_alloc_one_kernel() and __pte_alloc_one(). There is no functional change for the kernel PTE allocation. The difference for the user PTEs, is that the clear_pte_table() is now called after pgtable_page_ctor() and the addition of __GFP_ACCOUNT to the GFP flags. The conversion to the generic version of pte_free_kernel() removes the NULL check for pte. The pte_free() version on arm is identical to the generic one and can be simply dropped.

arm: remove ARCH_SELECT_MEMORY_MODEL
Patch series "remove ARCH_SELECT_MEMORY_MODEL where it has no effect". For several architectures the ARCH_SELECT_MEMORY_MODEL has no real effect because the dependencies for the memory model are always evaluated to a single value. Remove the ARCH_SELECT_MEMORY_MODEL from the Kconfigs for these architectures. This patch (of 3): The ARCH_SELECT_MEMORY_MODEL in arch/arm/Kconfig is enabled only when ARCH_SPARSEMEM_ENABLE=y. But in this case, ARCH_SPARSEMEM_DEFAULT is also enabled and this in turn enables SPARSEMEM_MANUAL. Since there is no definition of ARCH_FLATMEM_ENABLE in arch/arm/Kconfig, SPARSEMEM_MANUAL is the only enabled memory model, hence the final selection will evaluate to SPARSEMEM=y. Since ARCH_SPARSEMEM_ENABLE is set to 'y' only by several sub-arch configurations, the default for must sub-arches would be the falback to FLATMEM regardless of ARCH_SELECT_MEMORY_MODEL.

USB / PHY patches for 5.3-rc1
Here is the big USB and PHY driver pull request for 5.3-rc1.
Lots of stuff here, all of which has been in linux-next for a while with
no reported issues. Nothing is earth-shattering, just constant forward
progress for more devices supported and cleanups and small fixes:
- USB gadget driver updates and fixes
- new USB gadget driver for some hardware, followed by a quick revert
of those patches as they were not ready to be merged...
- PHY driver updates
- Lots of new driver additions and cleanups with a few fixes mixed in.

Pull USB / PHY updates from Greg KH:
"Here is the big USB and PHY driver pull request for 5.3-rc1.
Lots of stuff here, all of which has been in linux-next for a while
with no reported issues. Nothing is earth-shattering, just constant
forward progress for more devices supported and cleanups and small
fixes:
- USB gadget driver updates and fixes
- new USB gadget driver for some hardware, followed by a quick revert
of those patches as they were not ready to be merged...
- PHY driver updates
- Lots of new driver additions and cleanups with a few fixes mixed
in"
