irq_work_raise should not cause a decrementer exception unless it is
called from NMI context. Doing so often just results in an immediate
masked decrementer interrupt:
<...>-550 90d... 4us : update_curr_rt <-dequeue_task_rt
<...>-550 90d... 5us : dbs_update_util_handler <-update_curr_rt
<...>-550 90d... 6us : arch_irq_work_raise <-irq_work_queue
<...>-550 90d... 7us : soft_nmi_interrupt <-soft_nmi_common
<...>-550 90d... 7us : printk_nmi_enter <-soft_nmi_interrupt
<...>-550 90d.Z. 8us : rcu_nmi_enter <-soft_nmi_interrupt
<...>-550 90d.Z. 9us : rcu_nmi_exit <-soft_nmi_interrupt
<...>-550 90d... 9us : printk_nmi_exit <-soft_nmi_interrupt
<...>-550 90d... 10us : cpuacct_charge <-update_curr_rt
The soft_nmi_interrupt here is the call into the watchdog, due to the
decrementer interrupt firing with irqs soft-disabled. This is
harmless, but sub-optimal.
When it's not called from NMI context or with interrupts enabled, mark
the decrementer pending in the irq_happened mask directly, rather than
having the masked decrementer interupt handler do it. This will be
replayed at the next local_irq_enable. See the comment for details.

When IODA2 creates a PE, it creates an IOMMU table with it_ops::free
set to pnv_ioda2_table_free() which calls pnv_pci_ioda2_table_free_pages().
Since iommu_tce_table_put() calls it_ops::free when the last reference
to the table is released, explicit call to pnv_pci_ioda2_table_free_pages()
is not needed so let's remove it.
This should fix double free in the case of PCI hotuplug as
pnv_pci_ioda2_table_free_pages() does not reset neither
iommu_table::it_base nor ::it_size.
This was not exposed by SRIOV as it uses different code path via
pnv_pcibios_sriov_disable().
IODA1 does not inialize it_ops::free so it does not have this issue.

Our goal is to handle ERR_FATAL errors similarly, whether they are reported
via AER or via DPC. A previous commit changed AER so it handles ERR_FATAL
by calling driver .remove() methods and resetting the Link. DPC already
does that (although the Link reset is done automatically by hardware and
happens before we call the driver .remove() methods).
Restructure the DPC code so it calls the same pcie_do_fatal_recovery()
interface used by AER. This makes it clearer that we want to use the same
path.
Implement the .reset_link() method used by pcie_do_fatal_recovery(). For
DPC, the actual reset is done automatically by hardware, so we really only
have to wait for the Link to be inactive, then release the Port from DPC.

PCIe ERR_NONFATAL errors mean a particular transaction is unreliable but
the Link is otherwise fully functional (PCIe r4.0, sec 6.2.2).
The AER driver handles these by logging the error details and calling
driver-supplied pci_error_handlers callbacks. It does not reset downstream
devices, does not remove them from the PCI subsystem, does not re-enumerate
them, and does not call their driver .remove() or .probe() methods.
But DPC driver previously enabled DPC on ERR_NONFATAL, so if the hardware
supports DPC, these errors caused a Link reset (performed automatically by
the hardware), followed by the DPC driver removing affected devices (which
calls their .remove() methods), bringing the Link back up, and
re-enumerating (which calls driver .probe() methods).
Disable ERR_NONFATAL DPC triggering so these errors will only be handled by
AER. This means drivers won't have to deal with different usage of their
pci_error_handlers callbacks and .probe() and .remove() methods based on
whether the platform has DPC support.

There is currently a mismatch between the resources that will trigger
the e820_pmem driver to register/load and the resources that will
actually be surfaced as pmem ranges. register_e820_pmem() uses
walk_iomem_res_desc() which includes children and siblings. In contrast,
e820_pmem_probe() only considers top level resources. For example the
following resource tree results in the driver being loaded, but no
resources being registered:
398000000000-39bfffffffff : PCI Bus 0000:ae
39be00000000-39bf07ffffff : PCI Bus 0000:af
39be00000000-39beffffffff : 0000:af:00.0
39be10000000-39beffffffff : Persistent Memory (legacy)
Fix this up to allow definitions of "legacy" pmem ranges anywhere in
system-physical address space. Not that it is a recommended or safe to
define a pmem range in PCI space, but it is useful for debug /
experimentation, and the restriction on being a top-level resource was
arbitrary.

Here are 4 small bugfixes for some char/misc drivers. Well, really 3
fixes and one fix for one of those fixes due to problems found by 0-day.
This resolves some reported issues with the hwtracing drivers, and a
reported regression for the thunderbolt subsystem. All of these have
been in linux-next for a while now with no reported problems.
