xen-pciback: allow compiling on other archs than x86
Xen-pciback driver was designed to be built for x86 only. But it
can also be used by other architectures, e.g. Arm.
Currently PCI backend implements multiple functionalities at a time,
such as:
1. It is used as a database for assignable PCI devices, e.g. xl
pci-assignable-{add|remove|list} manipulates that list. So, whenever
the toolstack needs to know which PCI devices can be passed through
it reads that from the relevant sysfs entries of the pciback.
2. It is used to hold the unbound PCI devices list, e.g. when passing
through a PCI device it needs to be unbound from the relevant device
driver and bound to pciback (strictly speaking it is not required
that the device is bound to pciback, but pciback is again used as a
database of the passed through PCI devices, so we can re-bind the
devices back to their original drivers when guest domain shuts down)
3. Device reset for the devices being passed through
4. Para-virtualised use-cases support
The para-virtualised part of the driver is not always needed as some
architectures, e.g. Arm or x86 PVH Dom0, are not using backend-frontend
model for PCI device passthrough.
For such use-cases make the very first step in splitting the
xen-pciback driver into two parts: Xen PCI stub and PCI PV backend
drivers.
For that add new configuration options CONFIG_XEN_PCI_STUB and
CONFIG_XEN_PCIDEV_STUB, so the driver can be limited in its
functionality, e.g. no support for para-virtualised scenario.
x86 platform will continue using CONFIG_XEN_PCIDEV_BACKEND for the
fully featured backend driver.

x86/xen: switch initial pvops IRQ functions to dummy ones
The initial pvops functions handling irq flags will only ever be called before interrupts are being enabled. So switch them to be dummy functions: - xen_save_fl() can always return 0 - xen_irq_disable() is a nop - xen_irq_enable() can BUG() Add some generic paravirt functions for that purpose.

x86/xen: remove xen_have_vcpu_info_placement flag
The flag xen_have_vcpu_info_placement was needed to support Xen hypervisors older than version 3.4, which didn't support the VCPUOP_register_vcpu_info hypercall. Today the Linux kernel requires at least Xen 4.0 to be able to run, so xen_have_vcpu_info_placement can be dropped (in theory the flag was used to ensure a working kernel even in case of the VCPUOP_register_vcpu_info hypercall failing for other reasons than the hypercall not being supported, but the only cases covered by the flag would be parameter errors, which ought not to be made anyway). This allows to let some functions return void now, as they can never fail.

xen: Fix implicit type conversion
The variable 'i' is defined as UINT. However, in the for_each_possible_cpu
its value is assigned to -1. That doesn't make sense and in the
cpumask_next() it is implicitly type converted to INT. It is universally
accepted that the implicit type conversion is terrible. Also, having the
good programming custom will set an example for others. Thus, it might be
better to change the definition of 'i' from UINT to INT.

xen/x86: restrict PV Dom0 identity mapping
When moving away RAM pages, there having been a mapping of those is not a proper indication that instead MMIO should be mapped there. At the point in time this effectively covers the low megabyte only. Mapping of that is, however, the job of init_mem_mapping(). Comparing the two one can also spot that we've been wrongly (or at least inconsistently) using PAGE_KERNEL_IO here. Simply zap any such mappings instead.

xen/x86: adjust handling of the L3 user vsyscall special page table
Marking the page tableas pinned without ever actually pinning is was probably an oversight in the first place. The main reason for the change is more subtle, though: The write of the one present entry each here and in the subsequently allocated L2 table engage a code path in the hypervisor which exists only for thought-to-be-broken guests: An mmu- update operation to a page which is neither a page table nor marked writable. The hypervisor merely assumes (or should I say "hopes") that the fact that a writable reference to the page can be obtained means it is okay to actually write to that page in response to such a hypercall. While there make all involved code and data dependent upon X86_VSYSCALL_EMULATION (some code was already).

xen/x86: streamline set_pte_mfn()
In preparation for restoring xen_set_pte_init()'s original behavior of avoiding hypercalls, make set_pte_mfn() no longer use the standard set_pte() code path. That one is more complicated than the alternative of simply using an available hypercall directly. This way we can avoid introducing a fair number (2k on my test system) of cases where the hypervisor would trap-and-emulate page table updates.

Pull selinux updates from Paul Moore:
- Add LSM/SELinux/Smack controls and auditing for io-uring.
As usual, the individual commit descriptions have more detail, but we
were basically missing two things which we're adding here:
+ establishment of a proper audit context so that auditing of
io-uring ops works similarly to how it does for syscalls (with
some io-uring additions because io-uring ops are *not* syscalls)
+ additional LSM hooks to enable access control points for some of
the more unusual io-uring features, e.g. credential overrides.
The additional audit callouts and LSM hooks were done in conjunction
with the io-uring folks, based on conversations and RFC patches
earlier in the year.
- Fixup the binder credential handling so that the proper credentials
are used in the LSM hooks; the commit description and the code
comment which is removed in these patches are helpful to understand
the background and why this is the proper fix.
- Enable SELinux genfscon policy support for securityfs, allowing
improved SELinux filesystem labeling for other subsystems which make
use of securityfs, e.g. IMA.

Tracing updates for 5.16:

Various hardening fixes and cleanups for 5.16-rc1
Hi Linus,
Please, pull the following hardening fixes and cleanups that I've
been collecting during the last development cycle. All of them have
been baking in linux-next.
Fix -Wcast-function-type error:
- firewire: Remove function callback casts (Oscar Carter)
Fix application of sizeof operator:
- firmware/psci: fix application of sizeof to pointer (jing yangyang)
Replace open coded instances with size_t saturating arithmetic helpers:
- assoc_array: Avoid open coded arithmetic in allocator arguments (Len Baker)
- writeback: prefer struct_size over open coded arithmetic (Len Baker)
- aio: Prefer struct_size over open coded arithmetic (Len Baker)
- dmaengine: pxa_dma: Prefer struct_size over open coded arithmetic (Len Baker)
Flexible array transformation:
- KVM: PPC: Replace zero-length array with flexible array member (Len Baker)
Use 2-factor argument multiplication form:
- nouveau/svm: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)
- xfs: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)
Thanks

overflow updates for v5.16-rc1
The end goal of the current buffer overflow detection work[0] is to gain full compile-time and run-time coverage of all detectable buffer overflows seen via array indexing or memcpy(), memmove(), and memset(). The str*() family of functions already have full coverage. While much of the work for these changes have been on-going for many releases (i.e. 0-element and 1-element array replacements, as well as avoiding false positives and fixing discovered overflows[1]), this series contains the foundational elements of several related buffer overflow detection improvements by providing new common helpers and FORTIFY_SOURCE changes needed to gain the introspection required for compiler visibility into array sizes. Also included are a handful of already Acked instances using the helpers (or related clean-ups), with many more waiting at the ready to be taken via subsystem-specific trees[2]. The new helpers are: - struct_group() for gaining struct member range introspection. - memset_after() and memset_startat() for clearing to the end of structures. - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs. Also included is the beginning of the refactoring of FORTIFY_SOURCE to support memcpy() introspection, fix missing and regressed coverage under GCC, and to prepare to fix the currently broken Clang support. Finishing this work is part of the larger series[0], but depends on all the false positives and buffer overflow bug fixes to have landed already and those that depend on this series to land. As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time and run-time tests are added for FORTIFY_SOURCE and the mem*()-family functions respectively. The compile time tests have found a legitimate (though corner-case) bug[6] already. Please note that the appearance of "panic" and "BUG" in the FORTIFY_SOURCE refactoring are the result of relocating existing code, and no new use of those code-paths are expected nor desired. Finally, there are two tree-wide conversions for 0-element arrays and flexible array unions to gain sane compiler introspection coverage that result in no known object code differences. After this series (and the changes that have now landed via netdev and usb), we are very close to finally being able to build with -Warray-bounds and -Wzero-length-bounds. However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build. Hopefully these can be solved soon.

However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build.

cpu-to-thread_info update for v5.16-rc1
Cross-architecture update to move task_struct::cpu back into thread_info
on arm64, x86, s390, powerpc, and riscv. All Acked by arch maintainers.
Quoting Ard Biesheuvel:
"Move task_struct::cpu back into thread_info
Keeping CPU in task_struct is problematic for architectures that define
raw_smp_processor_id() in terms of this field, as it requires
linux/sched.h to be included, which causes a lot of pain in terms of
circular dependencies (aka 'header soup')
This series moves it back into thread_info (where it came from) for all
architectures that enable THREAD_INFO_IN_TASK, addressing the header
soup issue as well as some pointless differences in the implementations
of task_cpu() and set_task_cpu()."

arm64 updates for 5.16
- Support for the Arm8.6 timer extensions, including a self-synchronising
view of the system registers to elide some expensive ISB instructions.
- Exception table cleanup and rework so that the fixup handlers appear
correctly in backtraces.
- A handful of miscellaneous changes, the main one being selection of
CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK.
- More mm and pgtable cleanups.
- KASAN support for "asymmetric" MTE, where tag faults are reported
synchronously for loads (via an exception) and asynchronously for
stores (via a register).
- Support for leaving the MMU enabled during kexec relocation, which
significantly speeds up the operation.
- Minor improvements to our perf PMU drivers.
- Improvements to the compat vDSO build system, particularly when
building with LLVM=1.
- Preparatory work for handling some Coresight TRBE tracing errata.
- Cleanup and refactoring of the SVE code to pave the way for SME
support in future.
- Ensure SCS pages are unpoisoned immediately prior to freeing them
when KASAN is enabled for the vmalloc area.
- Try moving to the generic pfn_valid() implementation again now that
the DMA mapping issue from last time has been resolved.
- Numerous improvements and additions to our FPSIMD and SVE selftests.
