arm64: dts: ti: k3-j721e-main: Add hwspinlock node
The Main NavSS block on J721E SoCs contains a HwSpinlock IP instance that is same as the IP on AM65x SoCs and similar to the IP on some OMAP SoCs. Add the DT node for this on J721E SoCs. The node is present within the Main NavSS block, and is added as a child node under the cbass_main_navss interconnect node.

There are 8 instances of gpio modules in main domain divided into 2 groups: - Group1: gpio0, gpio2, gpio4, gpio6 - Group2: gpio1, gpio3, gpio5, gpio7 Groups are created to provide protection between two different processor virtual worlds. There are x gpio lines coming out of each group. Each module in a group has equal x gpio lines pinned out. There is a top level mux for selecting the module instance for each pin coming out of group. Exactly one module can be selected to control the corresponding pin. This muxing can be controlled along the pad mux configuration registers. Group1 pins out 128 lines(8 banks). Group 2 pins out 36 lines(2 banks). Add DT nodes for each module instance in the main domain. Users should make sure that correct gpio instance is selected in their pad configuration.

arm64: entry: SP Alignment Fault doesn't write to FAR_EL1
Comparing the arm-arm's pseudocode for AArch64.PCAlignmentFault() with
AArch64.SPAlignmentFault() shows that SP faults don't copy the faulty-SP
to FAR_EL1, but this is where we read from, and the address we provide
to user-space with the BUS_ADRALN signal.
For user-space this value will be UNKNOWN due to the previous ERET to
user-space. If the last value is preserved, on systems with KASLR or KPTI
this will be the user-space link-register left in FAR_EL1 by tramp_exit().
Fix this to retrieve the original sp_el0 value, and pass this to
do_sp_pc_fault().
SP alignment faults from EL1 will cause us to take the fault again when
trying to store the pt_regs. This eventually takes us to the overflow
stack. Remove the ESR_ELx_EC_SP_ALIGN check as we will never make it
this far.

arm64: Force SSBS on context switch
On a CPU that doesn't support SSBS, PSTATE[12] is RES0. In a system
where only some of the CPUs implement SSBS, we end-up losing track of
the SSBS bit across task migration.
To address this issue, let's force the SSBS bit on context switch.

arm64: stacktrace: Better handle corrupted stacks
The arm64 stacktrace code is careful to only dereference frame records in valid stack ranges, ensuring that a corrupted frame record won't result in a faulting access. However, it's still possible for corrupt frame records to result in infinite loops in the stacktrace code, which is also undesirable. This patch ensures that we complete a stacktrace in finite time, by keeping track of which stacks we have already completed unwinding, and verifying that if the next frame record is on the same stack, it is at a higher address. As this has turned out to be particularly subtle, comments are added to explain the procedure.

We keep this in a separate branch to avoid cross-branch conflicts, but most of the material here is fairly boring -- some new drivers turned on for hardware since they were merged, and some refreshed files due to time having moved a lot of entries around. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAl0yUy8PHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3xMsP+wawhEwoH9kgFkzs4OHVw66BHULejrtYF92Q piOiLhqHgtLnDjz7oV9e3LNUDfsAutPOscDlYzmEU+v4qhisxF66jnmPzv7ppByJ c4WJkj38TYo1qyZ3SD/9UY9jHQFZyDj3qeeS6LJdSJVMIf7fL/XsjPFeF3QCrA6w tabVAgFnx49QD1ucCXedbpBFVpRD+TP2nRSwkVGVDHJ5NKl2z6Pi55hNdWsSpJ/E Smn02vZolfVrbzvWn+3p+SETSOcwNN0F5DWEbDmlwIrMNhtaV8V91Z1vwB7Zu4pq khLw8hLpYX9cPnqVHu8aUChu5gAOc7UKU52an9qcguznTp2kvTsaBDPRW/hA8hsr s6sBL0FmNfVesaGw10zLTYfLbfO1Osq3/8dP3u5kJHfhb4veINy09sjSL76On04c DuljTQvURH5lXAbt3J4GRnN/x8yZ+LNoT3htElo+59TmR/QOBjQXP0oOPXRVyrDQ +oHdFuw3LjU9ZxUiTkvqaQag217SFpbuUdMR7RO/dtKlwpAnuofWXy+zDFQ1UcxU +p7asIo+3Nwiea8MQeB4+XArW20lpTEJUs3GVrqQvCOfmzttS9q842gTPDex8id2 b4VER5MJLV2EQ9JKU1cfMd5IVak9fbnIIgh5tD/UzVVP/s+RwdJQgMeT/RqoCrZc PTMbqCVX =Ysfd -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC defconfig updates from Olof Johansson: "We keep this in a separate branch to avoid cross-branch conflicts, but most of the material here is fairly boring -- some new drivers turned on for hardware since they were merged, and some refreshed files due to time having moved a lot of entries around" * tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (47 commits) ARM: configs: multi_v5: Remove duplicate ASPEED options arm64: defconfig: Enable CONFIG_KEYBOARD_SNVS_PWRKEY as module ARM: imx_v6_v7_defconfig: Enable CONFIG_ARM_IMX_CPUFREQ_DT defconfig: arm64: enable i.MX8 SCU octop driver arm64: defconfig: Add i.MX SCU SoC info driver arm64: defconfig: Enable CONFIG_QORIQ_THERMAL ARM: imx_v6_v7_defconfig: Select CONFIG_NVMEM_SNVS_LPGPR arm64: defconfig: ARM_IMX_CPUFREQ_DT=m ARM: imx_v6_v7_defconfig: Add TPM PWM support by default ARM: imx_v6_v7_defconfig: Enable the OV2680 camera driver ARM: imx_v6_v7_defconfig: Enable CONFIG_THERMAL_STATISTICS arm64: defconfig: NVMEM_IMX_OCOTP=y for imx8m ARM: multi_v7_defconfig: enable STMFX pinctrl support arm64 defconfig: enable LVM support ARM: configs: multi_v5: Add more ASPEED devices arm64: defconfig: Add Tegra194 PCIe driver ARM: configs: aspeed: Add new drivers ARM: exynos_defconfig: Enable Panfrost and Lima drivers ARM: multi_v7_defconfig: Enable Panfrost and Lima drivers arm64 defconfig: enable Mellanox cards ... |

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.

Merge branch 'akpm' (patches from Andrew)
Merge yet more updates from Andrew Morton:
"The rest of MM and a kernel-wide procfs cleanup.
Summary of the more significant patches:
- Patch series "mm/memory_hotplug: Factor out memory block
devicehandling", v3. David Hildenbrand.
Some spring-cleaning of the memory hotplug code, notably in
drivers/base/memory.c
- "mm: thp: fix false negative of shmem vma's THP eligibility". Yang
Shi.
Fix /proc/pid/smaps output for THP pages used in shmem.
- "resource: fix locking in find_next_iomem_res()" + 1. Nadav Amit.
Bugfix and speedup for kernel/resource.c
- Patch series "mm: Further memory block device cleanups", David
Hildenbrand.
More spring-cleaning of the memory hotplug code.
- Patch series "mm: Sub-section memory hotplug support". Dan
Williams.
Generalise the memory hotplug code so that pmem can use it more
completely. Then remove the hacks from the libnvdimm code which
were there to work around the memory-hotplug code's constraints.
- "proc/sysctl: add shared variables for range check", Matteo Croce.
We have about 250 instances of
int zero;
...
.extra1 = &zero,
in the tree. This is a tree-wide sweep to make all those private
"zero"s and "one"s use global variables.
Alas, it isn't practical to make those two global integers const"

proc/sysctl: add shared variables for range check
mm: migrate: remove unused mode argument
mm/sparsemem: cleanup 'section number' data types
libnvdimm/pfn: stop padding pmem namespaces to section alignment
libnvdimm/pfn: fix fsdax-mode namespace info-block zero-fields
mm/devm_memremap_pages: enable sub-section remap

mm/memory_hotplug: allow arch_remove_memory() without CONFIG_MEMORY_HOTREMOVE
We want to improve error handling while adding memory by allowing to use
arch_remove_memory() and __remove_pages() even if
CONFIG_MEMORY_HOTREMOVE is not set to e.g., implement something like:
arch_add_memory()
rc = do_something();
if (rc) {
arch_remove_memory();
}
We won't get rid of CONFIG_MEMORY_HOTREMOVE for now, as it will require
quite some dependencies for memory offlining.

arm64/mm: add temporary arch_remove_memory() implementation
A proper arch_remove_memory() implementation is on its way, which also cleanly removes page tables in arch_add_memory() in case something goes wrong. As we want to use arch_remove_memory() in case something goes wrong during memory hotplug after arch_add_memory() finished, let's add a temporary hack that is sufficient enough until we get a proper implementation that cleans up page table entries. We will remove CONFIG_MEMORY_HOTREMOVE around this code in follow up patches.

arm64: mm: implement pte_devmap support
In order for things like get_user_pages() to work on ZONE_DEVICE memory, we need a software PTE bit to identify device-backed PFNs.

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

arch: replace _BITUL() in kernel-space headers with BIT()
Now that BIT() can be used from assembly code, we can safely replace _BITUL() with equivalent BIT(). UAPI headers are still required to use _BITUL(), but there is no more reason to use it in kernel headers. BIT() is shorter.

This is the bulk of pin control changes for the v5.3 kernel
cycle:
Core changes:
- Device links can optionally be added between a pin control
producer and its consumers. This will affect how the system
power management is handled: a pin controller will not suspend
before all of its consumers have been suspended. This was
necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense
to make this default in the long run. Right now it is
opt-in per driver.
- Drive strength can be specified in microamps. With decreases
in silicon technology, milliamps isn't granular enough, let's
make it possible to select drive strengths in microamps. Right
now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a
product line of NXP).
- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in
addition to muxing.
- The Qualcomm drivers can now reserve some GPIOs as taken
aside and not usable for users. This is used in ACPI systems
to take out some GPIO lines used by the BIOS so that
noone else (neither kernel nor userspace) will play with them
by mistake and crash the machine.
- A slew of refurbishing around the Aspeed drivers (board
management controllers for servers) in preparation for the
new Aspeed AST2600 SoC.
- A slew of improvements over the SH PFC drivers as usual.
- Misc cleanups and fixes.

asm-generic: remove ptrace.h
The asm-generic changes for 5.3 consist of a cleanup series from Christoph Hellwig, who explains: "asm-generic/ptrace.h is a little weird in that it doesn't actually implement any functionality, but it provided multiple layers of macros that just implement trivial inline functions. We implement those directly in the few architectures and be off with a much simpler design."

mm/pgtable: drop pgtable_t variable from pte_fn_t functions
Drop the pgtable_t variable from all implementation for pte_fn_t as none of them use it. apply_to_pte_range() should stop computing it as well. Should help us save some cycles.

arm64: switch to generic version of pte allocation
The PTE allocations in arm64 are identical to the generic ones modulo the GFP flags. Using the generic pte_alloc_one() functions ensures that the user page tables are allocated with __GFP_ACCOUNT set. The arm64 definition of PGALLOC_GFP is removed and replaced with GFP_PGTABLE_USER for p[gum]d_alloc_one() for the user page tables and GFP_PGTABLE_KERNEL for the kernel page tables. The KVM memory cache is now using GFP_PGTABLE_USER. The mappings created with create_pgd_mapping() are now using GFP_PGTABLE_KERNEL. The conversion to the generic version of pte_free_kernel() removes the NULL check for pte. The pte_free() version on arm64 is identical to the generic one and can be simply dropped.
