The xe_info_init_early() is a place where we initialize those of
the xe->info fields that do not require any additional hardware

to avoid breaking the kunit helper, which also calls this function,
keep their initialization separate in sub-function so we can easily

Currently the queue name is only assigned after the drm scheduler instance
has been created. This loses information with all logging or debug
workqueue facilities so lets re-order things a bit so the name gets
assigned in time.
To be able to assign a GuC ID early we split the allocation into
reservation and publish phases.
First, with the submission state lock held, we reserve the ID in the GuC
ID manager, which serves as an authoritative source of truth. Then we can
drop the lock and reserve entries in the exec queue lookup XArray. This
can be lockless since the NULL entries are invisible both to the kernel
and userspace. Only after the queue has been fully created we replace the
reserved entries with the queue pointer, which can be done locklessly for
single width queues.

Pull irqchip driver fixes from Ingo Molnar:
- Fix the hardware probing error path of the renesas-rzt2h
irqchip driver
- Fix the exynos-combiner irqchip driver on -rt kernels
by turning the IRQ controller spinlock into a raw spinlock
* tag 'irq-urgent-2026-05-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irqchip/renesas-rzt2h: Use pm_runtime_put_sync() in probe error path
irqchip/exynos-combiner: Switch to raw_spinlock
- Fix debugobjects regression on -rt kernels: don't fill the
pool (which uses a coarse lock) if ->pi_blocked_on, because
that messes up the priority inheritance of callers.

Hygon Family 18h CPUs are derived from AMD Family 17h (Zen1) silicon and
share the same erratum #1235: hardware may read a stale IsRunning=1 bit
during ICR write emulation and silently fail to generate an
AVIC_IPI_FAILURE_TARGET_NOT_RUNNING VM-Exit on the sending vCPU.
The absence of the VM-Exit causes KVM to miss the required wakeup of
blocking target vCPUs, leading to hung vCPUs and unbounded delays in
guest execution.
Extend the existing AMD Family 17h erratum #1235 workaround to also cover
Hygon Family 18h. With IPI virtualization disabled, KVM never sets
IsRunning=1 in the Physical ID table, so every non-self IPI generates a
VM-Exit and is correctly emulated.

When KVM_CAP_X86_APIC_BUS_CYCLES_NS is queried on a specific VM, return the
VM's configured APIC bus frequency, not KVM's default. Aside from the fact
that returning the default frequency is blatantly wrong if userspace has
changed the frequency, returning the configured frequency means userspace
can blindly trust the result, e.g. when filling PV CPUID information that
communicates the APIC bus frequency to the guest.
