HiSilicon KunPeng920 and KunPeng930 have devices that appear as PCI but are
actually on the AMBA bus. These fake PCI devices can support SVA via the
SMMU stall feature.
DT systems can indicate this in the device tree, but ACPI systems don't
have that mechanism, so add a "dma-can-stall" property manually for them.

Previously we assumed that all Root Ports and Switch Downstream Ports
supported Link Bandwidth Notification. Per spec, this is only required
for Ports supporting Links wider than x1 and/or multiple Link speeds
(PCIe r5.0, sec 7.5.3.6).
Because we assumed all Ports supported it, we tried to set up a Bandwidth
Notification IRQ, which failed for devices that don't support IRQs at all,
which meant pcieport didn't attach to the Port at all.
Check the Link Bandwidth Notification Capability bit and enable the service
only when the Port supports it.

Some systems, e.g., HiSilicon KunPeng920 and KunPeng930, have devices that
appear as PCI but are actually on the AMBA bus. Some of these fake PCI
devices support a PASID-like feature and they do have a working PASID
capability even though they do not use the PCIe Transport Layer Protocol
and do not support TLP prefixes.
Add a pasid_no_tlp bit for this "PASID works without TLP prefixes" case and
update pci_enable_pasid() so it can enable PASID on these devices.
Set this bit for HiSilicon KunPeng920 and KunPeng930.

pci_resource_end() can be 0 only when pci_resource_start() is 0.
Otherwise, it is definitely an error. In this case, pci_resource_len()
should be regarded as 0. Therefore, determining whether
pci_resource_start() and pci_resource_end() are both 0 can be reduced to
determining only whether pci_resource_end() is 0.
Although only one condition judgment is reduced, the macro function
pci_resource_len() is widely referenced in the kernel. I used defconfig to
compile the latest kernel on X86, and its binary code size was reduced by
about 3KB.

Previously, the ACPI_COMPANION() of a pci_dev was usually set by
acpi_bind_one() in this path:
pci_device_add
pci_configure_device
pci_init_capabilities
device_add
device_platform_notify
acpi_platform_notify
acpi_device_notify # KOBJ_ADD
acpi_bind_one
ACPI_COMPANION_SET
However, things like pci_configure_device() and pci_init_capabilities()
that run before device_add() need the ACPI_COMPANION, e.g.,
acpi_pci_bridge_d3() uses a _DSD method to learn about D3 support. These
places had special-case code to manually look up the ACPI_COMPANION.
Set the ACPI_COMPANION earlier, in pci_setup_device(), so it will be
available while configuring the device. This covers both paths to creating
pci_dev objects:
pci_scan_single_device # for normal non-SR-IOV devices
pci_scan_device
pci_setup_device
pci_set_acpi_fwnode
pci_device_add
pci_iov_add_virtfn # for SR-IOV virtual functions
pci_setup_device
pci_set_acpi_fwnode
Also move the OF fwnode setup to the same spot.

was an exception because it relied on a separate pcie_has_flr() function
instead of taking a "probe" argument.

The pciconfig_read() syscall reads PCI configuration space using
hardware-dependent config accessors.
If the read fails on PCI, most accessors don't return an error; they
pretend the read was successful and got ~0 data from the device, so the
syscall returns success with ~0 data in the buffer.
When the accessor does return an error, pciconfig_read() normally fills the
user's buffer with ~0 and returns an error in errno. But after
e4585da22ad0 ("pci syscall.c: Switch to refcounting API"), we don't fill
the buffer with ~0 for the EPERM "user lacks CAP_SYS_ADMIN" error.
Userspace may rely on the ~0 data to detect errors, but after e4585da22ad0,
that would not detect CAP_SYS_ADMIN errors.
Restore the original behaviour of filling the buffer with ~0 when the
CAP_SYS_ADMIN check fails.

The ASMedia ASM1062 SATA controller advertises Max_Payload_Size_Supported
of 512, but in fact it cannot handle incoming TLPs with payload size of
512.
We discovered this issue on PCIe controllers capable of MPS = 512 (Aardvark
and DesignWare), where the issue presents itself as an External Abort.
Bjorn Helgaas says:
Probably ASM1062 reports a Malformed TLP error when it receives a data
payload of 512 bytes, and Aardvark, DesignWare, etc convert this to an
arm64 External Abort. [1]
To avoid this problem, limit the ASM1062 Max Payload Size Supported to 256
bytes, so we set the Max Payload Size of devices that may send TLPs to the
ASM1062 to 256 or less.

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

- Fix 'perf probe' use of debuginfo files by build id.
- If a DSO has both dynsym and symtab ELF sections, read from both
when loading the symbol table, fixing a problem processing Fedora
32 glibc DSOs.
Libraries:
- Add grouping of events to libperf, from code in tools/perf,
allowing libperf users to use that mode.
Misc:
- Filter plt stubs from the 'perf probe --functions' output.
- Update UAPI header copies for asound, DRM, mman-common.h and the
ones affected by the quotactl_fd syscall"

Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to
local_lock") folded in a workaround patch for pahole that was unable to
deal with zero-sized percpu structures.
A superior workaround is achieved with commit a0b8200d06ad ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").
This patch reverts the dummy field and the pahole version check.
Fixes: dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock")

- Fix preempt_count initialization.
- Rework call_on_stack() macro to add proper type handling and avoid
possible register corruption.
- More error prone "register asm" removal and fixes.
- Fix syscall restarting when multiple signals are coming in. This adds
minimalistic trampolines to vdso so we can return from signal without
using the stack which requires pgm check handler hacks when NX is
enabled.
- Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after
switch to generic entry.
- Fix protected virtualization secure storage access exception
handling.
- Make machine check C handler always enter with DAT enabled and move
register validation to C code.
- Fix tinyconfig boot problem by avoiding MONITOR CALL without
CONFIG_BUG.
- Increase asm symbols alignment to 16 to make it consistent with
compilers.
- Enable concurrent access to the CPU Measurement Counter Facility.
- Add support for dynamic AP bus size limit and rework ap_dqap to deal
with messages greater than recv buffer.
