The kv*alloc()-family was missing kvcalloc(). Adding this allows for
2-argument multiplication conversions of kvzalloc(a * b, ...) into
kvcalloc(a, b, ...).

cmap->len can get close to INT_MAX/2, allowing for an integer overflow in
allocation. This uses kmalloc_array() instead to catch the condition.

There is potential for the size and len fields in ubifs_data_node to be
too large causing either a negative value for the length fields or an
integer overflow leading to an incorrect memory allocation. Likewise,
when the len field is small, an integer underflow may occur.

Pull more xfs updates from Darrick Wong:
"Here's the second round of patches for XFS for 4.18. Most of the
commits are small cleanups, bug fixes, and continued strengthening of
metadata verifiers; the bulk of the diff is the conversion of the
fs/xfs/ tree to use SPDX tags.
This series has been run through a full xfstests run over the weekend
and through a quick xfstests run against this morning's master, with
no major failures reported.
Summary:
- Strengthen metadata checking to avoid ASSERTing on bad disk
contents
- Validate btree records that are being retrieved for clients
- Strengthen root inode verification
- Convert license blurbs to SPDX tags
- Enable changing DAX flag on directories
- Fix some writeback deadlocks in reflink
- Refactor out some old xfs helpers
- Move type verifiers to a separate file
- Fix some fuzzer crashes
- Various other bug fixes"

The functions that were used in the emulation of fxrstor, fxsave, sgdt and
sidt were originally meant for task switching, and as such they did not
check privilege levels. This is very bad when the same functions are used
in the emulation of unprivileged instructions. This is CVE-2018-10853.
The obvious fix is to add a new argument to ops->read_std and ops->write_std,
which decides whether the access is a "system" access or should use the
processor's CPL.

Int the next patch the emulator's .read_std and .write_std callbacks will
grow another argument, which is not needed in kvm_read_guest_virt and

Currently, when IO to DS fails, client returns the layout and
retries against the MDS. However, then on umounting (inode eviction)
it returns the layout again.
This is because pnfs_return_layout() was changed in
commit d78471d32b ("pnfs/blocklayout: set PNFS_LAYOUTRETURN_ON_ERROR")
to always set NFS_LAYOUT_RETURN_REQUESTED so even if we returned
the layout, it will be returned again. Instead, let's also check
if we have already marked the layout invalid.

Pull ARM SoC device tree updates from Olof Johansson:
"As always, a large number of DT updates. Too many to enumerate them
all, but at a glance:
New SoCs introduced in this release:
- Amlogic:
+ Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some
set top boxes and other products.
- Mediatek:
+ MT7623A, which is a flavor of the MT7623 family with other
on-chip ethernet options.
- Qualcomm:
+ SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
(Cortex-A75/A55 derivative) SoC that's one of the current
high-end mobile SoCs.
It's great to see mainline support for it. So far, you can't do
much with it, since a lot of peripherals are not yet in the DTs
but driver support for USB, GPU and other pieces are starting to
trickle in. This might end up being a well-supported SoC
upstream if the momentum keeps up.
- Renesas:
+ R8A77990, a.k.a R-Car E3, a new automotive
entertainment-targeted SoC. Currently only one Cortex-A53 CPU is
enabled, we are eagerly awaiting more. So far, basic drivers
such as serial, gpios, PMU and ethernet are enabled.
+ R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
GPU. Same here, basic set of drivers such as serial, gpios and
ethernet enabled, and SMP support is also forthcoming.
- STMicroelectronics:
+ STM32F469, very similar tih STM32F429 but with display support
Enhancements to SoCs/platforms (DTS contents, some driver portions
might not be in yet):
- Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
- Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets
- Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces

Pull ARM SoC platform updates from Olof Johansson:
"Here are the main updates for SoC support (besides DT additions) for
ARM 32- and 64-bit platforms. The branch also contains defconfig
updates to turn on drivers and options as needed on the various
platforms.
The largest parts of the delta are from cleanups moving platform data
and board file setup of TI platforms to ti-sysc bus drivers. There are
also some sweeping changes of eeprom and nand setup on Davinci, i.MX
and other platforms.
Samsung is removing support for Exynos5440, which was an oddball SoC
that hasn't been seen much use in designs.
Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
Linus Walleij is also removing support for ux500 (Sony Ericsson)
U8540/9540 SoCs that never made it to significant mass production and
products"

This reverts commit b468620f2a.
It turns out that this broke drm on AMD platforms. Quoting Gabriel C:
"I can confirm reverting b468620f2a fixes
that issue for me.
The GPU is working fine with SME enabled.
Now with working GPU :) I can also confirm performance is back to
normal without doing any other workarounds"
Christan König analyzed it partially:
"As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs()
in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled"
and Christoph Hellwig responded:
"I think the prime issue is that dma_direct_alloc respects the dma
mask. Which we don't need if actually using the iommu. This would be
mostly harmless exept for the the SEV bit high in the address that
makes the checks fail.
For now I'd say revert this commit for 4.17/4.18-rc and I'll look into
addressing these issues properly"

ntb_transport_create_queue() is never called in atomic context.
ntb_transport_create_queue() is only called by ntb_netdev_probe(),
which is set as ".probe" in struct ntb_transport_client.
Despite never getting called from atomic context,
ntb_transport_create_queue() calls kzalloc_node() with GFP_ATOMIC,
which does not sleep for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.
This is found by a static analysis tool named DCNS written by myself.
And I also manually check it

Al noted that the semantics of the ia64 perfmon mmap() is really wrong,
and can cause serious VM problems. Before we look at whether it needs
to be fixed, let's see if anybody even uses it, and mark it broken. It
may be that we can just remove the code entirely.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've mainly focused on discard, aka unmap, control
along with fstrim for Android-specific usage model. In addition, we've
fixed writepage flow which returned EAGAIN previously resulting in EIO
of fsync(2) due to mapping's error state. In order to avoid old MM bug
[1], we decided not to use __GFP_ZERO for the mapping for node and
meta page caches. As always, we've cleaned up many places for future
fsverity and symbol conflicts.
Enhancements:
- do discard/fstrim in lower priority considering fs utilization
- split large discard commands into smaller ones for better responsiveness
- add more sanity checks to address syzbot reports
- add a mount option, fsync_mode=nobarrier, which can reduce # of cache flushes
- clean up symbol namespace with modified function names
- be strict on block allocation and IO control in corner cases
Bug fixes:
- don't use __GFP_ZERO for mappings
- fix error reports in writepage to avoid fsync() failure
- avoid selinux denial on CAP_RESOURCE on resgid/resuid
- fix some subtle race conditions in GC/atomic writes/shutdown
- fix overflow bugs in sanity_check_raw_super
- fix missing bits on get_flags
Clean-ups:
- prepare the generic flow for future fsverity integration
- fix some broken coding standard"
