Use device file descriptors and regions to represent pagemaps on
foreign or local devices.
The underlying files are type-checked at madvise time, and
references are kept on the drm_pagemap as long as there is are
madvises pointing to it.
Extend the madvise preferred_location UAPI to support the region
instance to identify the foreign placement.
v2:
- Improve UAPI documentation. (Matt Brost)
- Sanitize preferred_mem_loc.region_instance madvise. (Matt Brost)
- Clarify madvise drm_pagemap vs xe_pagemap refcounting. (Matt Brost)
- Don't allow a foreign drm_pagemap madvise without a fast
interconnect.
v3:
- Add a comment about reference-counting in xe_devmem_open() and
remove the reference-count get-and-put. (Matt Brost)

Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>
blkdev_pr_read_keys() takes num_keys from userspace and uses it to
calculate the allocation size for keys_info via struct_size(). While
there is a check for SIZE_MAX (integer overflow), there is no upper
bound validation on the allocation size itself.
A malicious or buggy userspace can pass a large num_keys value that
doesn't trigger overflow but still results in an excessive allocation
attempt, causing a warning in the page allocator when the order exceeds
MAX_PAGE_ORDER.
Fix this by introducing PR_KEYS_MAX to limit the number of keys to
a sane value. This makes the SIZE_MAX check redundant, so remove it.
Also switch to kvzalloc/kvfree to handle larger allocations gracefully.

A recent commit modified struct irdma_alloc_ucontext_resp by adding a

the offset of the data members other than m68k. Reported by
scripts/check-uapi.sh:
==== ABI differences detected in include/rdma/irdma-abi.h from 1dd7bde2e91c -> HEAD ====
[C] 'struct irdma_alloc_ucontext_resp' changed:

1 data member insertion:

Change the size back to the previous version, and remove the implicit

On a few 32-bit architectures, the newly added ib_user_service_rec

Add explicit padding into the rdma_ucm_query_ib_service_resp and
rdma_ucm_resolve_ib_service structures that embed it, so that the layout
is compatible across all of them.
This is an ABI change on i386, aligning it with x86_64 and the other

Extend `struct mnt_id_req` to take in a fd and introduce STATMOUNT_BY_FD
flag. When a valid fd is provided and STATMOUNT_BY_FD is set, statmount
will return mountinfo about the mount the fd is on.
This even works for "unmounted" mounts (mounts that have been umounted
using umount2(mnt, MNT_DETACH)), if you have access to a file descriptor
on that mount. These "umounted" mounts will have no mountpoint and no
valid mount namespace. Hence, we unset the STATMOUNT_MNT_POINT and
STATMOUNT_MNT_NS_ID in statmount.mask for "unmounted" mounts.
In case of STATMOUNT_BY_FD, given that we already have access to an fd
on the mount, accessing mount information without a capability check
seems fine because of the following reasons:
- All fs related information is available via fstatfs() without any
capability check.
- Mount information is also available via /proc/pid/mountinfo (without
any capability check).
- Given that we have access to a fd on the mount which tells us that we
had access to the mount at some point (or someone that had access gave
us the fd). So, we should be able to access mount info.

The rest for 6.19 merge window. The only slightly large change is
the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio

Multi Queue is a new mode of execution supported by the compute and
blitter copy command streamers (CCS and BCS, respectively). It is an
enhancement of the existing hardware architecture and leverages the
same submission model. It enables support for efficient, parallel
execution of multiple queues within a single context. All the queues
of a group must use the same address space (VM).
The new DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE execution queue
property supports creating a multi queue group and adding queues to
a queue group. All queues of a multi queue group share the same
context.
A exec queue create ioctl call with above property specified with value
DRM_XE_SUPER_GROUP_CREATE will create a new multi queue group with the
queue being created as the primary queue (aka q0) of the group. To add
secondary queues to the group, they need to be created with the above
property with id of the primary queue as the value. The properties of
the primary queue (like priority, timeslice) applies to the whole group.
So, these properties can't be set for secondary queues of a group.
Once destroyed, the secondary queues of a multi queue group can't be
replaced. However, they can be dynamically added to the group up to a
total of 64 queues per group. Once the primary queue is destroyed,
secondary queues can't be added to the queue group.
v2: Remove group->lock, fix xe_exec_queue_group_add()/delete()

group->list_lock, add XE_BO_FLAG_GGTT_INVALIDATE for cgp bo,

Before this patch, the kernel was saving any flags set by the userspace,
even unknown ones. This doesn't cause critical issues because the kernel
is only looking at specific ones. But on the other hand, endpoints dumps
could tell the userspace some recent flags seem to be supported on older
kernel versions.
Instead, ignore all unknown flags when parsing them. By doing that, the
userspace can continue to set unsupported flags, but it has a way to
verify what is supported by the kernel.
Note that it sounds better to continue accepting unsupported flags not
to change the behaviour, but also that eases things on the userspace
side by adding "optional" endpoint types only supported by newer kernel
versions without having to deal with the different kernel versions.
A note for the backports: there will be conflicts in mptcp.h on older
versions not having the mentioned flags, the new line should still be
added last, and the '5' needs to be adapted to have the same value as
the last entry.

commit 0f0c8a6983db ("drm/amdkfd: Trap handler support for expert
scheduling mode") introduced support for a trap handler when expert
scheduling mode. However userspace needs to know whether or not a trap
handler support is present.
Bump the KFD IOCTL API so that userspace can key off this to decide.

This commit implemetns a new ioctl AMDKFD_IOC_CREATE_PROCESS
that creates a new secondary kfd_progress on the FD.
To keep backward compatibility, userspace programs need to invoke
this ioctl explicitly on a FD to create a secondary
kfd_process which replacing its primary kfd_process.
This commit bumps ioctl minor version.

In the context of the amdgpu uAPI, the PRT flag is referring only
to unmapped pages of a partially resident texture (aka. sparse

Virtual addresses marked with this flag behave as follows:
- Reads return zero
- Writes are discarded

Here is the big set of staging driver updates for 6.19-rc1. Only thing
"major" in here is that two subsystems, gpib and vc04 have moved out of
the staging tree into the "real" portion of the kernel, which is great
to see. Other than that, the rest of the changes are just tiny coding
style cleanups, nothing earth-shattering.
All of these have been in linux-next for a while with no reported

- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.
