HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation. It is not about the compiler support.
For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.
I moved the 'select' lines to keep the alphabetical sorting.

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.

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
variant when available, or array_size() and array3_size() as needed
(Kees)"

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.

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
- 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

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"

Pull arm64 updates from Catalin Marinas:
"Apart from the core arm64 and perf changes, the Spectre v4 mitigation
touches the arm KVM code and the ACPI PPTT support touches drivers/
(acpi and cacheinfo). I should have the maintainers' acks in place.
Summary:
- Spectre v4 mitigation (Speculative Store Bypass Disable) support
for arm64 using SMC firmware call to set a hardware chicken bit
- ACPI PPTT (Processor Properties Topology Table) parsing support and
enable the feature for arm64
- Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
primary motivation is Scalable Vector Extensions which requires
more space on the signal frame than the currently defined
MINSIGSTKSZ
- ARM perf patches: allow building arm-cci as module, demote
dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous
cleanups
- cmpwait() WFE optimisation to avoid some spurious wakeups
- L1_CACHE_BYTES reverted back to 64 (for performance reasons that
have to do with some network allocations) while keeping
ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual
hardware Cache Writeback Granule
- Turn LSE atomics on by default in Kconfig
- Kernel fault reporting tidying
- Some #include and miscellaneous cleanups"

Commit 17c2895 ("arm64: Abstract syscallno manipulation") abstracts
out the pt_regs.syscallno value for a syscall cancelled by a tracer
as NO_SYSCALL, and provides helpers to set and check for this
condition. However, the way this was implemented has the
unintended side-effect of disabling part of the syscall restart
logic.
This comes about because the second in_syscall() check in
do_signal() re-evaluates the "in a syscall" condition based on the
updated pt_regs instead of the original pt_regs. forget_syscall()
is explicitly called prior to the second check in order to prevent
restart logic in the ret_to_user path being spuriously triggered,
which means that the second in_syscall() check always yields false.
This triggers a failure in
tools/testing/selftests/seccomp/seccomp_bpf.c, when using ptrace to
suppress a signal that interrups a nanosleep() syscall.
Misbehaviour of this type is only expected in the case where a
tracer suppresses a signal and the target process is either being
single-stepped or the interrupted syscall attempts to restart via
-ERESTARTBLOCK.
This patch restores the old behaviour by performing the
in_syscall() check only once at the start of the function.

Currently the PTE special supports is turned on in per architecture
header files. Most of the time, it is defined in
arch/*/include/asm/pgtable.h depending or not on some other per
architecture static definition.
This patch introduce a new configuration variable to manage this
directly in the Kconfig files. It would later replace
__HAVE_ARCH_PTE_SPECIAL.
Here notes for some architecture where the definition of
__HAVE_ARCH_PTE_SPECIAL is not obvious:
arm
__HAVE_ARCH_PTE_SPECIAL which is currently defined in
arch/arm/include/asm/pgtable-3level.h which is included by
arch/arm/include/asm/pgtable.h when CONFIG_ARM_LPAE is set.
So select ARCH_HAS_PTE_SPECIAL if ARM_LPAE.
powerpc
__HAVE_ARCH_PTE_SPECIAL is defined in 2 files:
- arch/powerpc/include/asm/book3s/64/pgtable.h
- arch/powerpc/include/asm/pte-common.h
The first one is included if (PPC_BOOK3S & PPC64) while the second is
included in all the other cases.
So select ARCH_HAS_PTE_SPECIAL all the time.
sparc:
__HAVE_ARCH_PTE_SPECIAL is defined if defined(__sparc__) &&
defined(__arch64__) which are defined through the compiler in
sparc/Makefile if !SPARC32 which I assume to be if SPARC64.
So select ARCH_HAS_PTE_SPECIAL if SPARC64
There is no functional change introduced by this patch.

The numa mask subset check can often lead to system hang or crash during
CPU hotplug and system suspend operation if NUMA is disabled. This is
mostly observed on HMP systems where the CPU compute capacities are
different and ends up in different scheduler domains. Since
cpumask_of_node is returned instead core_sibling, the scheduler is
confused with incorrect cpumasks(e.g. one CPU in two different sched
domains at the same time) on CPU hotplug.
Lets disable the NUMA siblings checks for the time being, as NUMA in
socket machines have LLC's that will assure that the scheduler topology
isn't "borken".
The NUMA check exists to assure that if a LLC within a socket crosses
NUMA nodes/chiplets the scheduler domains remain consistent. This code will
likely have to be re-enabled in the near future once the NUMA mask story
is sorted. At the moment its not necessary because the NUMA in socket
machines LLC's are contained within the NUMA domains.
Further, as a defensive mechanism during hot-plug, lets assure that the
LLC siblings are also masked.
