08af78d7a5 ARM: SoC fixes for 4.18-rc
A smaller batch for the end of the week (let's see if I can keep the
 weekly cadence going for once).
 
 All medium-grade fixes here, nothing worrisome:
  - Fixes for some fairly old bugs around SD card write-protect detection
    and GPIO interrupt assignments on Davinci.
  - Wifi module suspend fix for Hikey.
  - Minor DT tweaks to fix inaccuracies for Amlogic platforms, on of
    which solves booting with third-party u-boot.

1c38f4afd5 ARM64: dts: meson-gxl: fix Mali GPU compatible string
meson-gxl-mali.dtsi is only used on GXL SoCs. Thus it should use the GXL
specific compatible string instead of the GXBB one.
For now this is purely cosmetic since the (out-of-tree) lima driver for
this GPU currently uses the "arm,mali-450" match instead of the SoC
specific one. However, update the .dts to match the documentation since
this driver behavior might change in the future.

6d28d57751 ARM64: dts: meson-axg: fix ethernet stability issue
Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to
suffer from the kind of stability issue.

Doing an iperf3 download test, we can see a significant number of LPI
interrupts on the tx path. After a short while (5 to 15 seconds), the
network connection dies. If using rootfs over NFS, the connection may
also break during the boot sequence.

We still don't have a real explanation for this problem so let's disable
EEE once again.

48e21ded04 ARM64: dts: meson-gx: fix ATF reserved memory region
Vendor firmware/uboot has different reserved regions depending on
firmware version, but current codebase reserves the same regions on
GXL and GXBB, so move the additional reserved memory region to common
.dtsi.

Found when putting a recent vendor u-boot on meson-gxbb-p200.

d5b4885b1d ARM64: dts: meson: disable sd-uhs modes on the libretech-cc
There is a problem with the sd-uhs mode when doing a soft reboot.
Switching back from 1.8v to 3.3v messes with the card, which no longer
respond (timeout errors). According to the specification, we should
perform a card reset (power cycling the card) but this is something we
cannot control on this design.

Then the only solution to restore the communication with the card is an
"unplug-plug" which is not acceptable

Until we find a solution, if any, disable the sd-uhs modes on this design.
For the people using uhs at the moment, there will a performance drop as
a result.

Commit 7f0b1bf045 ("arm64: Fix barriers used for page table modifications")
fixed a reported issue with fixmap page-table entries not being visible
to the walker due to a missing DSB instruction. At the same time, it added
ISB instructions to the arm64 set_{pte,pmd,pud} functions, which are not
required by the architecture and make little sense in isolation.

Remove the redundant ISBs.

429388682d arm64: Avoid flush_icache_range() in alternatives patching code
The implementation of flush_icache_range() includes instruction sequences
which are themselves patched at runtime, so it is not safe to call from
the patching framework.

This patch reworks the alternatives cache-flushing code so that it rolls
its own internal D-cache maintenance using DC CIVAC before invalidating
the entire I-cache after all alternatives have been applied at boot.
Modules don't cause any issues, since flush_icache_range() is safe to
call by the time they are loaded.

c432c08805 arm64: defconfig: renormalize based on recent additions
The defconfig has drifted over time, as Kconfig entries have changed order
or default values. Several maintainers ended up running 'savedefconfig'
themselves which caused a cascade of conflicts. Let's do it once and
for all in our tree before -rc2 instead.

71c8fc0c96 arm64: mm: Ensure writes to swapper are ordered wrt subsequent cache maintenance
When rewriting swapper using nG mappings, we must performance cache
maintenance around each page table access in order to avoid coherency
problems with the host's cacheable alias under KVM. To ensure correct
ordering of the maintenance with respect to Device memory accesses made
with the Stage-1 MMU disabled, DMBs need to be added between the
maintenance and the corresponding memory access.

This patch adds a missing DMB between writing a new page table entry and
performing a clean+invalidate on the same line.

2955bcc8c3 KVM: arm64: Avoid mistaken attempts to save SVE state for vcpus
Commit e6b673b ("KVM: arm64: Optimise FPSIMD handling to reduce
guest/host thrashing") uses fpsimd_save() to save the FPSIMD state
for a vcpu when scheduling the vcpu out.  However, currently
current's value of TIF_SVE is restored before calling fpsimd_save()
which means that fpsimd_save() may erroneously attempt to save SVE
state from the vcpu.  This enables current's vector state to be
polluted with guest data.  current->thread.sve_state may be
unallocated or not large enough, so this can also trigger a NULL
dereference or buffer overrun.

Instead of this, TIF_SVE should be configured properly for the
guest when calling fpsimd_save() with the vcpu context loaded.

This patch ensures this by delaying restoration of current's
TIF_SVE until after the call to fpsimd_save().

b3eb56b629 KVM: arm64/sve: Fix SVE trap restoration for non-current tasks
Commit e6b673b ("KVM: arm64: Optimise FPSIMD handling to reduce
guest/host thrashing") attempts to restore the configuration of
userspace SVE trapping via a call to fpsimd_bind_task_to_cpu(), but
the logic for determining when to do this is not correct.

The patch makes the errnoenous assumption that the only task that
may try to enter userspace with the currently loaded FPSIMD/SVE
register content is current.  This may not be the case however:  if
some other user task T is scheduled on the CPU during the execution
of the KVM run loop, and the vcpu does not try to use the registers
in the meantime, then T's state may be left there intact.  If T
happens to be the next task to enter userspace on this CPU then the
hooks for reloading the register state and configuring traps will
be skipped.

(Also, current never has SVE state at this point anyway and should
always have the trap enabled, as a side-effect of the ioctl()
syscall needed to reach the KVM run loop in the first place.)

This patch instead restores the state of the EL0 trap from the
state observed at the most recent vcpu_load(), ensuring that the
trap is set correctly for the loaded context (if any).

b045e4d0f3 KVM: arm64: Don't mask softirq with IRQs disabled in vcpu_put()
Commit e6b673b ("KVM: arm64: Optimise FPSIMD handling to reduce
guest/host thrashing") introduces a specific helper
kvm_arch_vcpu_put_fp() for saving the vcpu FPSIMD state during
vcpu_put().

This function uses local_bh_disable()/_enable() to protect the
FPSIMD context manipulation from interruption by softirqs.

This approach is not correct, because vcpu_put() can be invoked
either from the KVM host vcpu thread (when exiting the vcpu run
loop), or via a preempt notifier.  In the former case, only
preemption is disabled.  In the latter case, the function is called
from inside __schedule(), which means that IRQs are disabled.

Use of local_bh_disable()/_enable() with IRQs disabled is considerd
an error, resulting in lockdep splats while running VMs if lockdep
is enabled.

This patch disables IRQs instead of attempting to disable softirqs,
avoiding the problem of calling local_bh_enable() with IRQs
disabled in the __schedule() path.  This creates an additional
interrupt blackout during vcpu run loop exit, but this is the rare
case and the blackout latency is still less than that of
__schedule().

6ebdf4db8f arm64: Introduce sysreg_clear_set()
Currently we have a couple of helpers to manipulate bits in particular
sysregs:

 * config_sctlr_el1(u32 clear, u32 set)

 * change_cpacr(u64 val, u64 mask)

The parameters of these differ in naming convention, order, and size,
which is unfortunate. They also differ slightly in behaviour, as
change_cpacr() skips the sysreg write if the bits are unchanged, which
is a useful optimization when sysreg writes are expensive.

Before we gain yet another sysreg manipulation function, let's
unify these with a common helper, providing a consistent order for
clear/set operands, and the write skipping behaviour from
change_cpacr(). Code will be migrated to the new helper in subsequent
patches.

they should be cleared on allocation. In case of IOMMU-based dma-mapping
implementation such buffer clearing was missing in the code path for

doesn't honor __GFP_ZERO flag. This patch fixes this issue. For more

d148eac0e7 Kbuild: rename HAVE_CC_STACKPROTECTOR config variable
HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation.  It is not about the compiler support.

For the consistency with commit 050e9baa9d ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.

I moved the 'select' lines to keep the alphabetical sorting.

Linus Torvalds
050e9baa9d Kbuild: rename CC_STACKPROTECTOR[_STRONG] config variables
The changes to automatically test for working stack protector compiler
support in the Kconfig files removed the special STACKPROTECTOR_AUTO
option that picked the strongest stack protector that the compiler
supported.

That was all a nice cleanup - it makes no sense to have the AUTO case
now that the Kconfig phase can just determine the compiler support
directly.

HOWEVER.

It also meant that doing "make oldconfig" would now _disable_ the strong
stackprotector if you had AUTO enabled, because in a legacy config file,
the sane stack protector configuration would look like

  CONFIG_HAVE_CC_STACKPROTECTOR=y
  # CONFIG_CC_STACKPROTECTOR_NONE is not set
  # CONFIG_CC_STACKPROTECTOR_REGULAR is not set
  # CONFIG_CC_STACKPROTECTOR_STRONG is not set
  CONFIG_CC_STACKPROTECTOR_AUTO=y

and when you ran this through "make oldconfig" with the Kbuild changes,
it would ask you about the regular CONFIG_CC_STACKPROTECTOR (that had
been renamed from CONFIG_CC_STACKPROTECTOR_REGULAR to just
CONFIG_CC_STACKPROTECTOR), but it would think that the STRONG version
used to be disabled (because it was really enabled by AUTO), and would
disable it in the new config, resulting in:

  CONFIG_HAVE_CC_STACKPROTECTOR=y
  CONFIG_CC_HAS_STACKPROTECTOR_NONE=y
  CONFIG_CC_STACKPROTECTOR=y
  # CONFIG_CC_STACKPROTECTOR_STRONG is not set
  CONFIG_CC_HAS_SANE_STACKPROTECTOR=y

That's dangerously subtle - people could suddenly find themselves with
the weaker stack protector setup without even realizing.

The solution here is to just rename not just the old RECULAR stack
protector option, but also the strong one.  This does that by just
removing the CC_ prefix entirely for the user choices, because it really
is not about the compiler support (the compiler support now instead
automatially impacts _visibility_ of the options to users).

This results in "make oldconfig" actually asking the user for their
choice, so that we don't have any silent subtle security model changes.
The end result would generally look like this:

  CONFIG_HAVE_CC_STACKPROTECTOR=y
  CONFIG_CC_HAS_STACKPROTECTOR_NONE=y
  CONFIG_STACKPROTECTOR=y
  CONFIG_STACKPROTECTOR_STRONG=y
  CONFIG_CC_HAS_SANE_STACKPROTECTOR=y

where the "CC_" versions really are about internal compiler
infrastructure, not the user selections.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull more overflow updates from Kees Cook:
 "The rest of the overflow changes for v4.18-rc1.

  This includes the explicit overflow fixes from Silvio, further
  struct_size() conversions from Matthew, and a bug fix from Dan.

  But the bulk of it is the treewide conversions to use either the
  2-factor argument allocators (e.g. kmalloc(a * b, ...) into
  kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
  b) into vmalloc(array_size(a, b)).

  Coccinelle was fighting me on several fronts, so I've done a bunch of
  manual whitespace updates in the patches as well.

  Summary:

   - Error path bug fix for overflow tests (Dan)

   - Additional struct_size() conversions (Matthew, Kees)

   - Explicitly reported overflow fixes (Silvio, Kees)

   - Add missing kvcalloc() function (Kees)

   - Treewide conversions of allocators to use either 2-factor argument

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

b357bf6023 Small update for KVM.
* ARM: lazy context-switching of FPSIMD registers on arm64, "split"
 regions for vGIC redistributor
 
 * s390: cleanups for nested, clock handling, crypto, storage keys and
 control register bits
 
 * x86: many bugfixes, implement more Hyper-V super powers,
 implement lapic_timer_advance_ns even when the LAPIC timer
 is emulated using the processor's VMX preemption timer.  Two
 security-related bugfixes at the top of the branch.

8efcf34a26 ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or
 took a while longer for us to review and merge than usual and thus cut
 it a bit close to the merge window. We stage them in a separate branch
 and if things look good, we still send them up -- and that's the case
 here.
 
 This is mostly DT additions for Renesas platforms, adding IP block
 descriptions for existing and new SoCs.
 
 There are also some driver updates for Qualcomm platforms for SMEM/QMI
 and GENI, which is their generalized serial protocol interface.

721afaa2ae ARM: Device-tree updates
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
  - Marvell Berlin2CD: SMP support, thermal sensors
  - Mediatek MT7623: Highspeed DMA, audio support
  - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support
  - Renesas: Watchdog and PMU support across many platforms
  - Rockchip RK3399: USB3 OTG support
  - Samsung Exynos: Audio-over-HDMI on Odroid X/X2/U3
  - STMicro STM32: Lots of peripherals added to STM32MP175C
  - Uniphier: Ethernet support
 
 New boards:
 
  - Allwinner A20: Olimex A20-SOM-EVB-eMMC variant
  - Allwinner H2+: Libre Computer ALL-H3-CC (h2+ version)
  - Allwinner A33: Nintendo NES/SuperNES Classic Edition
  - Aspeed: S2600WF, Inventec Lanyang BMC, Portwell Neptune
  - Berlin2CD: Valve Steam Link
  - Broadcom BCM5301X: Luxul XAP-1610 and XWR-3150 V1
  - Broadcom: Raspberry Pi 3 B+
  - Mediatek MT7623N and MT7623A: reference boards
  - Meson 8M2: Tronsmart MXIII Plus
  - NXP i.MX: Engicam i.CoreM6, DHCOM iMX6 SOM, BTicino i.MX6DL Mamoj
  - Qualcomm MSM8974: Sony Xperia Z1 Compact support
  - Qualcomm SDM845: MTP development board
  - Renesas: Ebisu R8A77990 board
  - Renesas RZ/G1C: iwg23s: iWave G235-SDB
