99845faae7 drm: document better that drivers shouldn't use drm_minor directly
The documentation for struct drm_minor already states this, but that's
not always that easy to find.

Also due to historical reasons we still have the minor-centric
interfaces (like drm_debugfs_create_files), but since this is now
getting fixed we can put a few more pointers in place as to how this
should be done ideally. Note that debugfs isn't there yet for all
cases (debugfs files on kms objects like crtc/connector aren't
supported, neither debugfs files with full fops), so the debugfs side
of this is still rather aspirational and more for new users than
converting everything existing. todo.rst covers the additional work
needed already.

Motivated by some discussion with Rodrigo on irc about how drm/xe
should lay out its sysfs interfaces.

v2: Make the debugfs situation clearer in the commit message, but
don't elaborate more in the actual kerneldoc to avoid distracting from
the main message around sysfs (Jani)

Also fix some typos.

e8f60cd7db perf tools fixes for v6.2: 2nd batch
- Make 'perf kmem' cope with the removal of some kmem:kmem_cache_alloc_node and
   kmem:kmalloc_node in the 11e9734bcb ("mm/slab_common: unify NUMA and
   UMA version of tracepoints") commit, making sure it works with Linux >= 6.2 as well
   as with older kernels where those tracepoints are present.
 
 - Also make it handle the new "node" kmem:kmalloc and kmem:kmem_cache_alloc tracepoint
   field introduced in that same commit.
 
 - Fix hardware tracing PMU address filter duplicate symbol selection, that was
   preventing to match with static functions with the same name present in different
   object files.
 
 - Fix regression on what linux/types.h file gets used to build the "BPF prologue"
   'perf test' entry, the system one lacks the fmode_t definition used in this test,
   so provide that type in the test itself.
 
 - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the user asks for
   linking with the libbpf package provided by the distro, then it has to be >= 0.8.0.
   Using the libbpf supplied with the kernel would be a fallback in that case.
 
 - Fix the build when libbpf isn't available or explicitly disabled via NO_LIBBPF=1.
 
 - Don't try to install libtraceevent plugins as its not anymore in the kernel sources
   and will thus always fail.

310bc39546 KVM: x86/xen: Avoid deadlock by adding kvm->arch.xen.xen_lock leaf node lock
In commit 14243b3871 ("KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN
and event channel delivery") the clever version of me left some helpful
notes for those who would come after him:

       /*
        * For the irqfd workqueue, using the main kvm->lock mutex is
        * fine since this function is invoked from kvm_set_irq() with
        * no other lock held, no srcu. In future if it will be called
        * directly from a vCPU thread (e.g. on hypercall for an IPI)
        * then it may need to switch to using a leaf-node mutex for
        * serializing the shared_info mapping.
        */
       mutex_lock(&kvm->lock);

In commit 2fd6df2f2b ("KVM: x86/xen: intercept EVTCHNOP_send from guests")
the other version of me ran straight past that comment without reading it,
and introduced a potential deadlock by taking vcpu->mutex and kvm->lock
in the wrong order.

Solve this as originally suggested, by adding a leaf-node lock in the Xen
state rather than using kvm->lock for it.

977a300954 alpha: fix FEN fault handling
Type 3 instruction fault (FPU insn with FPU disabled) is handled
by quietly enabling FPU and returning.  Which is fine, except that
we need to do that both for fault in userland and in the kernel;
the latter *can* legitimately happen - all it takes is this:

.global _start
_start:
        call_pal 0xae
	lda $0, 0
	ldq $0, 0($0)

- call_pal CLRFEN to clear "FPU enabled" flag and arrange for
a signal delivery (SIGSEGV in this case).

Fixed by moving the handling of type 3 into the common part of
do_entIF(), before we check for kernel vs. user mode.

Incidentally, the check for kernel mode is unidiomatic; the normal
way to do that is !user_mode(regs).  The difference is that
the open-coded variant treats any of bits 63..3 of regs->ps being
set as "it's user mode" while the normal approach is to check just
the bit 3.  PS is a 4-bit register and regs->ps always will have
bits 63..4 clear, so the open-coded variant here is actually equivalent
to !user_mode(regs).  Harder to follow, though...

f188bdb5f1 iommu/x86: Replace IOMMU_CAP_INTR_REMAP with IRQ_DOMAIN_FLAG_ISOLATED_MSI
On x86 platforms when the HW can support interrupt remapping the iommu
driver creates an irq_domain for the IR hardware and creates a child MSI
irq_domain.

When the global irq_remapping_enabled is set, the IR MSI domain is
assigned to the PCI devices (by intel_irq_remap_add_device(), or
amd_iommu_set_pci_msi_domain()) making those devices have the isolated MSI
property.

Due to how interrupt domains work, setting IRQ_DOMAIN_FLAG_ISOLATED_MSI on
the parent IR domain will cause all struct devices attached to it to
return true from msi_device_has_isolated_msi(). This replaces the
IOMMU_CAP_INTR_REMAP flag as all places using IOMMU_CAP_INTR_REMAP also
call msi_device_has_isolated_msi()

Set the flag and delete the cap.

17cde5e601 genirq/msi: Add msi_device_has_isolated_msi()
This will replace irq_domain_check_msi_remap() in following patches.

The new API makes it more clear what "msi_remap" actually means from a
functional perspective instead of identifying an implementation specific
HW feature.

Isolated MSI means that HW modeled by an irq_domain on the path from the
initiating device to the CPU will validate that the MSI message specifies
an interrupt number that the device is authorized to trigger. This must
block devices from triggering interrupts they are not authorized to
trigger.  Currently authorization means the MSI vector is one assigned to
the device.

This is interesting for securing VFIO use cases where a rouge MSI (eg
created by abusing a normal PCI MemWr DMA) must not allow the VFIO
userspace to impact outside its security domain, eg userspace triggering
interrupts on kernel drivers, a VM triggering interrupts on the
hypervisor, or a VM triggering interrupts on another VM.

As this is actually modeled as a per-irq_domain property, not a global
platform property, correct the interface to accept the device parameter
and scan through only the part of the irq_domains hierarchy originating
from the source device.

Locate the new code in msi.c as it naturally only works with
CONFIG_GENERIC_MSI_IRQ, which also requires CONFIG_IRQ_DOMAIN and
IRQ_DOMAIN_HIERARCHY.
