accel/ivpu: Stop using hardcoded DRIVER_DATE
Hardcoded driver date is useless, so use kernel version as a driver date to make identifying .ko file easier. Also allow to pass DRIVER_DATE on build time to allow versioning the driver in case it is built out of the tree.

drm/ttm: Move swapped objects off the manager's LRU list
Resources of swapped objects remains on the TTM_PL_SYSTEM manager's LRU list, which is bad for the LRU walk efficiency. Rename the device-wide "pinned" list to "unevictable" and move also resources of swapped-out objects to that list. An alternative would be to create an "UNEVICTABLE" priority to be able to keep the pinned- and swapped objects on their respective manager's LRU without affecting the LRU walk efficiency. v2: - Remove a bogus WARN_ON (Christian König) - Update ttm_resource_[add|del] bulk move (Christian König) - Fix TTM KUNIT tests (Intel CI) v3: - Check for non-NULL bo->resource in ttm_bo_populate(). v4: - Don't move to LRU tail during swapout until the resource is properly swapped or there was a swapout failure. (Intel Ci) - Add a newline after checkpatch check. v5: - Introduce ttm_resource_is_swapped() to avoid a corner-case where a newly created resource was considered swapped. (Intel CI) v6: - Move an assert.

drm/xe/ptl: L3bank mask is not available on the media GT
On PTL platforms with media version 30.00, the fuse registers for reporting L3 bank availability to the GT just read out as ~0 and do not provide proper values. Xe does not use the L3 bank mask for anything internally; it only passes the mask through to userspace via the GT topology query. Since we don't have any way to get the real L3 bank mask, we don't want to pass garbage to userspace. Passing a zeroed mask or a copy of the primary GT's L3 bank mask would also be inaccurate and likely to cause confusion for userspace. The best approach is to simply not include L3 in the list of masks returned by the topology query in cases where we aren't able to provide a meaningful value. This won't change the behavior for any existing platforms (where we can always obtain L3 masks successfully for all GTs), it will only prevent us from mis-reporting bad information on upcoming platform(s). There's a good chance this will become a formal workaround in the future, but for now we don't have a lineage number so "no_media_l3" is used in place of a lineage as the OOB workaround descriptor. v2: - Re-calculate query size to properly match data returned. (Gustavo) - Update kerneldoc to clarify that the L3bank mask may not be included in the query results if the hardware doesn't make it available.

drm: add DRM_SET_CLIENT_NAME ioctl
Giving the opportunity to userspace to associate a free-form name with a drm_file struct is helpful for tracking and debugging. This is similar to the existing DMA_BUF_SET_NAME ioctl. Access to client_name is protected by a mutex, and the 'clients' debugfs file has been updated to print it. Userspace MR to use this ioctl: https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1428 If the string passed by userspace contains chars that would mess up output when it's going to be printed (in dmesg, fdinfo, etc), -EINVAL is returned. A 0-length string is a valid use, and clears the existing name.

sound fixes for 6.12-rc2

net: test for not too small csum_start in virtio_net_hdr_to_skb()
syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb->csum_start and thus
the transport header to an incorrect value.
We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

This scenario shows that all notification groups are in principle prone to this kind of a deadlock (previously, we considered only fanotify and dnotify to be problematic for other reasons) so make sure all allocations under group->mark_mutex happen with GFP_NOFS.

cpufreq: Avoid a bad reference count on CPU node
In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute.

net: Add netif_get_gro_max_size helper for GRO
Add a small netif_get_gro_max_size() helper which returns the maximum IPv4 or IPv6 GRO size of the netdevice. We later add a netif_get_gso_max_size() equivalent as well for GSO, so that these helpers can be used consistently instead of open-coded checks.

close_range(): fix the logics in descriptor table trimming
Cloning a descriptor table picks the size that would cover all currently opened files. That's fine for clone() and unshare(), but for close_range() there's an additional twist - we clone before we close, and it would be a shame to have close_range(3, ~0U, CLOSE_RANGE_UNSHARE) leave us with a huge descriptor table when we are not going to keep anything past stderr, just because some large file descriptor used to be open before our call has taken it out. Unfortunately, it had been dealt with in an inherently racy way - sane_fdtable_size() gets a "don't copy anything past that" argument (passed via unshare_fd() and dup_fd()), close_range() decides how much should be trimmed and passes that to unshare_fd(). The problem is, a range that used to extend to the end of descriptor table back when close_range() had looked at it might very well have stuff grown after it by the time dup_fd() has allocated a new files_struct and started to figure out the capacity of fdtable to be attached to that. That leads to interesting pathological cases; at the very least it's a QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes a snapshot of descriptor table one might have observed at some point. Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination of unshare(CLONE_FILES) with plain close_range(), ending up with a weird state that would never occur with unshare(2) is confusing, to put it mildly. It's not hard to get rid of - all it takes is passing both ends of the range down to sane_fdtable_size(). There we are under ->files_lock, so the race is trivially avoided. So we do the following: * switch close_files() from calling unshare_fd() to calling dup_fd(). * undo the calling convention change done to unshare_fd() in |

x86:
* KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or deleted.
The former does not have particularly noticeable overhead, but Intel's
TDX will require the guest to re-accept private pages if they are
dropped from the secure EPT, which is a non starter. Actually,
the only reason why this is not already being done is a bug which
was never fully investigated and caused VM instability with assigned
GeForce GPUs, so allow userspace to opt into the new behavior.
* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
* Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value at the ICR offset.
* Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
(the SHUTDOWN hits the VM altogether, not the nested guest)
* Overhaul the "unprotect and retry" logic to more precisely identify cases
where retrying is actually helpful, and to harden all retry paths against
putting the guest into an infinite retry loop.
* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
the shadow MMU.
* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
adding multi generation LRU support in KVM.
* Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
i.e. when the CPU has already flushed the RSB.
* Trace the per-CPU host save area as a VMCB pointer to improve readability
and cleanup the retrieval of the SEV-ES host save area.
* Remove unnecessary accounting of temporary nested VMCB related allocations.
* Set FINAL/PAGE in the page fault error code for EPT violations if and only
if the GVA is valid. If the GVA is NOT valid, there is no guest-side page
table walk and so stuffing paging related metadata is nonsensical.
* Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
emulating posted interrupt delivery to L2.
* Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
* Harden eVMCS loading against an impossible NULL pointer deref (really truly
should be impossible).
* Minor SGX fix and a cleanup.
* Misc cleanups
Generic:
* Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.
* Enable virtualization when KVM is loaded, not right before the first VM
is created. Together with the previous change, this simplifies a
lot the logic of the callbacks, because their very existence implies
virtualization is enabled.
* Fix a bug that results in KVM prematurely exiting to userspace for coalesced
MMIO/PIO in many cases, clean up the related code, and add a testcase.
* Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
the gpa+len crosses a page boundary, which thankfully is guaranteed to not
happen in the current code base. Add WARNs in more helpers that read/write
guest memory to detect similar bugs.
Selftests:
* Fix a goof that caused some Hyper-V tests to be skipped when run on bare
metal, i.e. NOT in a VM.
* Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.
* Explicitly include one-off assets in .gitignore. Past Sean was completely
wrong about not being able to detect missing .gitignore entries.
* Verify userspace single-stepping works when KVM happens to handle a VM-Exit
in its fastpath.
* Misc cleanups
