commit e307e6698165ca6508ed42c69cb1be76c8eb6a3c upstream.
It might be useful for applications to detect if a zero copy transfer with
SEND[MSG]_ZC was actually possible or not. The application can fallback to
plain SEND[MSG] in order to avoid the overhead of two cqes per request. Or
it can generate a log message that could indicate to an administrator that
no zero copy was possible and could explain degraded performance.

[ Upstream commit defbab270d45e32b068e7e73c3567232d745c60f ]
Commit bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining
of some byteswap operations") added __always_inline to swab functions
and commit 283d75737837 ("uapi/linux/stddef.h: Provide __always_inline to
userspace headers") added a definition of __always_inline for use in
exported headers when the kernel's compiler.h is not available.
However, since swab.h does not include stddef.h, if the header soup does
not indirectly include it, the definition of __always_inline is missing,
resulting in a compilation failure, which was observed compiling the
perf tool using exported headers containing this commit:
In file included from /usr/include/linux/byteorder/little_endian.h:12:0,
from /usr/include/asm/byteorder.h:14,
from tools/include/uapi/linux/perf_event.h:20,
from perf.h:8,
from builtin-bench.c:18:
/usr/include/linux/swab.h:160:8: error: unknown type name `__always_inline'
static __always_inline __u16 __swab16p(const __u16 *p)
Fix this by replacing the inclusion of linux/compiler.h with
linux/stddef.h to ensure that we pick up that definition if required,
without relying on it's indirect inclusion. compiler.h is then included
indirectly, via stddef.h.

[ Upstream commit 0c5e259b06a8efc69f929ad777ea49281bb58e37 ]
The user usually configures the number of sge through the max_send_sge
parameter when creating qp, and configures the maximum size of inline data
that can be sent through max_inline_data. Inline uses sge to fill data to
send. Expect the following:
1) When the sge space cannot hold inline data, the sge space needs to be
expanded to accommodate all inline data
2) When the sge space is enough to accommodate inline data, the upper
limit of inline data can be increased so that users can send larger
inline data
Currently case one is not implemented. When the inline data is larger than
the sge space, an error of insufficient sge space occurs. This part of
the code needs to be reimplemented according to the expected rules. The
calculation method of sge num is modified to take the maximum value of
max_send_sge and the sge for max_inline_data to solve this problem.
Fixes: 05201e01be93 ("RDMA/hns: Refactor process of setting extended sge")
Fixes: 30b707886aeb ("RDMA/hns: Support inline data in extented sge space for RC")

__DECLARE_FLEX_ARRAY is defined in include/uapi/linux/stddef.h but
doesn't seem to be explicitly included from include/uapi/linux/in.h,
which breaks BPF selftests builds (once we sync linux/stddef.h into
tools/include directory in the next patch). Fix this by explicitly
including linux/stddef.h.
Given this affects BPF CI and bpf tree, targeting this for bpf tree.
Fixes: 5854a09b4957 ("net/ipv4: Use __DECLARE_FLEX_ARRAY() helper")

PERF_MEM_LVLNUM_EXTN_MEM was introduced to cover CXL devices but it's
bit ambiguous name and also not generic enough to cover cxl.cache and

IMU is a new firmware for GFX11.
There are four means by which firmware version can be queried
from the driver: device attributes, vf2pf, debugfs,
and the AMDGPU_INFO_FW_VERSION option in the amdgpu info ioctl.
Add IMU as an option for those four methods.

Pull missed media updates from Mauro Carvalho Chehab:
"It seems I screwed-up my previous pull request: it ends up that only
half of the media patches that were in linux-next got merged in -rc1.
The script which creates the signed tags silently failed due to
5.19->6.0 so it ended generating a tag with incomplete stuff.
So here are the missing parts:
- a DVB core security fix
- lots of fixes and cleanups for atomisp staging driver
- old drivers that are VB1 are being moved to staging to be
deprecated
- several driver updates - mostly for embedded systems, but there are
also some things addressing issues with some PC webcams, in the UVC
video driver"

__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).
Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

The two structs internal to struct panfrost_dump_object_header were
named, but sadly that is incompatible with C++, causing an error: "an
anonymous union may only have public non-static data members".
However nothing refers to struct pan_reg_hdr and struct pan_bomap_hdr
and there's no need to export these definitions, so lets drop them. This
fixes the C++ build error with the minimum change in userspace API.

Addressing
When the idxd_user_drv driver is bound to a Work Queue (WQ) device
without IOMMU or with IOMMU Passthrough without Shared Virtual
Addressing (SVA), the application gains direct access to physical
memory via the device by programming physical address to a submitted
descriptor. This allows direct userspace read and write access to
arbitrary physical memory. This is inconsistent with the security
goals of a good kernel API.
Unlike vfio_pci driver, the IDXD char device driver does not provide any
ways to pin user pages and translate the address from user VA to IOVA or
PA without IOMMU SVA. Therefore the application has no way to instruct the
device to perform DMA function. This makes the char device not usable for
normal application usage.
Since user type WQ without SVA cannot be used for normal application usage
and presents the security issue, bind idxd_user_drv driver and enable user
type WQ only when SVA is enabled (i.e. user PASID is enabled).

Pull VFIO updates from Alex Williamson:
- Prune private items from vfio_pci_core.h to a new internal header,
fix missed function rename, and refactor vfio-pci interrupt defines
(Jason Gunthorpe)
- Create consistent naming and handling of ioctls with a function per
ioctl for vfio-pci and vfio group handling, use proper type args
where available (Jason Gunthorpe)
- Implement a set of low power device feature ioctls allowing userspace
to make use of power states such as D3cold where supported (Abhishek
Sahu)
- Remove device counter on vfio groups, which had restricted the page
pinning interface to singleton groups to account for limitations in
the type1 IOMMU backend. Document usage as limited to emulated IOMMU
devices, ie. traditional mdev devices where this restriction is
consistent (Jason Gunthorpe)
- Correct function prefix in hisi_acc driver incurred during previous
refactoring (Shameer Kolothum)
- Correct typo and remove redundant warning triggers in vfio-fsl driver
(Christophe JAILLET)
- Introduce device level DMA dirty tracking uAPI and implementation in
the mlx5 variant driver (Yishai Hadas & Joao Martins)
- Move much of the vfio_device life cycle management into vfio core,
simplifying and avoiding duplication across drivers. This also
facilitates adding a struct device to vfio_device which begins the
introduction of device rather than group level user support and fills
a gap allowing userspace identify devices as vfio capable without
implicit knowledge of the driver (Kevin Tian & Yi Liu)
- Split vfio container handling to a separate file, creating a more
well defined API between the core and container code, masking IOMMU
backend implementation from the core, allowing for an easier future
transition to an iommufd based implementation of the same (Jason
Gunthorpe)
- Attempt to resolve race accessing the iommu_group for a device
between vfio releasing DMA ownership and removal of the device from
the IOMMU driver. Follow-up with support to allow vfio_group to exist
with NULL iommu_group pointer to support existing userspace use cases
of holding the group file open (Jason Gunthorpe)
- Fix error code and hi/lo register manipulation issues in the hisi_acc
variant driver, along with various code cleanups (Longfang Liu)
- Fix a prior regression in GVT-g group teardown, resulting in
unreleased resources (Jason Gunthorpe)
- A significant cleanup and simplification of the mdev interface,
consolidating much of the open coded per driver sysfs interface
support into the mdev core (Christoph Hellwig)
- Simplification of tracking and locking around vfio_groups that fall
out from previous refactoring (Jason Gunthorpe)
