There is a code path in dequeue_entities() that can set the slice of a
sched_entity to U64_MAX, which sometimes results in a crash.

The offending case is when dequeue_entities() is called to dequeue a
delayed group entity, and then the entity's parent's dequeue is delayed.
In that case:

1. In the if (entity_is_task(se)) else block at the beginning of
   dequeue_entities(), slice is set to
   cfs_rq_min_slice(group_cfs_rq(se)). If the entity was delayed, then
   it has no queued tasks, so cfs_rq_min_slice() returns U64_MAX.
2. The first for_each_sched_entity() loop dequeues the entity.
3. If the entity was its parent's only child, then the next iteration
   tries to dequeue the parent.
4. If the parent's dequeue needs to be delayed, then it breaks from the
   first for_each_sched_entity() loop _without updating slice_.
5. The second for_each_sched_entity() loop sets the parent's ->slice to
   the saved slice, which is still U64_MAX.

This throws off subsequent calculations with potentially catastrophic
results. A manifestation we saw in production was:

6. In update_entity_lag(), se->slice is used to calculate limit, which
   ends up as a huge negative number.
7. limit is used in se->vlag = clamp(vlag, -limit, limit). Because limit
   is negative, vlag > limit, so se->vlag is set to the same huge
   negative number.
8. In place_entity(), se->vlag is scaled, which overflows and results in
   another huge (positive or negative) number.
9. The adjusted lag is subtracted from se->vruntime, which increases or
   decreases se->vruntime by a huge number.
10. pick_eevdf() calls entity_eligible()/vruntime_eligible(), which
    incorrectly returns false because the vruntime is so far from the
    other vruntimes on the queue, causing the
    (vruntime - cfs_rq->min_vruntime) * load calulation to overflow.
11. Nothing appears to be eligible, so pick_eevdf() returns NULL.
12. pick_next_entity() tries to dereference the return value of
    pick_eevdf() and crashes.

Dumping the cfs_rq states from the core dumps with drgn showed tell-tale
huge vruntime ranges and bogus vlag values, and I also traced se->slice
being set to U64_MAX on live systems (which was usually "benign" since
the rest of the runqueue needed to be in a particular state to crash).

Fix it in dequeue_entities() by always setting slice from the first
non-empty cfs_rq.

With ACPI in place, gicv2m_get_fwnode() is registered with the pci
subsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime
during a PCI host bridge probe. But, the call back is wrongly marked as
__init, causing it to be freed, while being registered with the PCI
subsystem and could trigger:

 Unable to handle kernel paging request at virtual address ffff8000816c0400

Some registers such as LOONGARCH_CSR_ESTAT and LOONGARCH_CSR_GINTC are
partly cleared with function _kvm_setcsr(). This comes from the hardware
specification, some bits are read only in VM mode, and however they can
be written in host mode. So they are partly cleared in VM mode, and can
be fully cleared in host mode.

These read only bits show pending interrupt or exception status. When VM
reset, the read-only bits should be cleared, otherwise vCPU will receive
unknown interrupts in boot stage.

Here registers LOONGARCH_CSR_ESTAT/LOONGARCH_CSR_GINTC are fully cleared
in ioctl KVM_REG_LOONGARCH_VCPU_RESET vCPU reset path.

LoongArch's huge_pte_offset() currently returns a pointer to a PMD slot
even if the underlying entry points to invalid_pte_table (indicating no
mapping). Callers like smaps_hugetlb_range() fetch this invalid entry
value (the address of invalid_pte_table) via this pointer.

The generic is_swap_pte() check then incorrectly identifies this address
as a swap entry on LoongArch, because it satisfies the "!pte_present()
&& !pte_none()" conditions. This misinterpretation, combined with a
coincidental match by is_migration_entry() on the address bits, leads to
kernel crashes in pfn_swap_entry_to_page().

Fix this at the architecture level by modifying huge_pte_offset() to
check the PMD entry's content using pmd_none() before returning. If the
entry is invalid (i.e., it points to invalid_pte_table), return NULL
instead of the pointer to the slot.

Currently, interrupts need to be disabled before single-step mode is
set, it requires that CSR_PRMD_PIE be cleared in save_local_irqflag()
which is called by setup_singlestep(), this is reasonable.

But in the first kprobe breakpoint exception, if the irq is enabled at
the beginning of do_bp(), it will not be disabled at the end of do_bp()
due to the CSR_PRMD_PIE has been cleared in save_local_irqflag(). So for
this case, it may corrupt exception context when restoring the exception
after do_bp() in handle_bp(), this is not reasonable.

In order to restore exception safely in handle_bp(), it needs to ensure
the irq is disabled at the end of do_bp(), so just add a local variable
to record the original interrupt status in the parent context, then use
it as the check condition to enable and disable irq in do_bp().

While at it, do the similar thing for other do_xyz() exception handlers
to make them more robust.

Pull vfs fixes from Christian Brauner:

 - For some reason we went from zero to three maintainers for HFS/HFS+
   in a matter of days. The lesson to learn from this might just be that
   we need to threaten code removal more often!?

 - Fix a regression introduced by enabling large folios for lage logical
   block sizes. This has caused issues for noref migration with large
   folios due to sleeping while in an atomic context.

   New sleeping variants of pagecache lookup helpers are introduced.
   These helpers take the folio lock instead of the mapping's private
   spinlock. The problematic users are converted to the sleeping
   variants and serialize against noref migration. Atomic users will
   bail on seeing the new BH_Migrate flag.

   This also shrinks the critical region of the mapping's private lock
   and the new blocking callers reduce contention on the spinlock for
   bdev mappings.

 - Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
   first bug is using a mountpoint that is located on a mount we're not
   holding a reference to. The second bug is putting the mountpoint
   after we've called namespace_unlock() as it's no longer guaranteed
   that it does stay a mountpoint.

 - Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
   just to query i_mode instead of simply querying the inode directly.
   This also avoids lifetime issues for the dm code by an earlier bugfix
   this cycle that moved bdev_statx() handling into vfs_getattr_nosec().

 - Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
