pcie_clear_device_status() resets the error bits in the PCIe Device Status
Register (PCI_EXP_DEVSTA).
Previously we did this unconditionally, but on ACPI systems, the _OSC AER
bit negotiates control of the AER capability. Per sec 4.5.1 of the System
Firmware Intermediary _OSC and DPC Updates ECN [1], this bit also covers
other error enable/status bits including the following:
Correctable Error Reporting Enable
Non-Fatal Error Reporting Enable
Fatal Error Reporting Enable
Unsupported Request Reporting Enable
These bits are all in the PCIe Device Control register (the ECN omitted
"Reporting", but I think that's a typo), so by implication the _OSC AER bit
also applies to the error status bits in the PCIe Device Status register:
Correctable Error Detected
Non-Fatal Error Detected
Fatal Error Detected
Unsupported Request Detected
Clear the PCIe Device Status error bits only when the OS controls the AER
capability and related error enable/status bits. If platform firmware
controls the AER capability, firmware is responsible for clearing these
bits.
One call path leading here is:
ghes_do_proc
ghes_handle_aer
aer_recover_queue
schedule_work(&aer_recover_work)
...
aer_recover_work_func
pcie_do_recovery
pcie_clear_device_status

pci_aer_clear_device_status() clears the error bits in the PCIe Device
Status Register (PCI_EXP_DEVSTA). Every PCIe device has this register,
regardless of whether it supports AER.
Rename pci_aer_clear_device_status() to pcie_clear_device_status() to make
clear that it is PCIe-specific but not AER-specific. Move it to
drivers/pci/pci.c, again since it's not AER-specific. No functional change
intended.

kobject_init_and_add() takes a reference even when it fails. If it returns
an error, kobject_put() must be called to clean up the memory associated
with the object.
When kobject_init_and_add() fails, call kobject_put() instead of kfree().

aer_correctable_error_string[] and aer_uncorrectable_error_string[] have
descriptions of AER error status bits. Add NULL entries to these tables so
all entries for bits 0-31 are defined. Then we don't have to check for
ARRAY_SIZE() when decoding a status word, which simplifies
__aer_print_error().

The method struct pci_error_handlers.error_detected() is defined and
documented as taking an 'enum pci_channel_state' for the second argument,
but most drivers use 'pci_channel_state_t' instead.
This 'pci_channel_state_t' is not a typedef for the enum but a typedef for
a bitwise type in order to have better/stricter typechecking.
Consolidate everything by using 'pci_channel_state_t' in the method's
definition, in the related helpers and in the drivers.
Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state'
with an anonymous 'enum'.
Note: Currently, from a typechecking point of view this patch changes
nothing because only the constants defined by the enum are bitwise, not the
enum itself (sparse doesn't have the notion of 'bitwise enum'). This may
change in some not too far future, hence the patch.

The pci_cfg_wait queue is used to prevent user-space config accesses to
devices while they are recovering from reset.
Previously we used these operations on pci_cfg_wait:
__add_wait_queue(&pci_cfg_wait, ...)
__remove_wait_queue(&pci_cfg_wait, ...)
wake_up_all(&pci_cfg_wait)
The wake_up acquires the wait queue lock, but the add and remove do not.
Originally these were all protected by the pci_lock, but cdcb33f982
("PCI: Avoid possible deadlock on pci_lock and p->pi_lock"), moved
wake_up_all() outside pci_lock, so it could race with add/remove
operations, which caused occasional kernel panics, e.g., during vfio-pci
hotplug/unplug testing:
Unable to handle kernel read from unreadable memory at virtual address ffff802dac469000
Resolve this by using wait_event() instead of __add_wait_queue() and
__remove_wait_queue(). The wait queue lock is held by both wait_event()
and wake_up_all(), so it provides mutual exclusion.
Fixes: cdcb33f982 ("PCI: Avoid possible deadlock on pci_lock and p->pi_lock")

When debugging an issue where I was asking the PCI machinery to enable a
set of MSI-X vectors, without falling back on MSI, I ran across a behaviour
which seems odd. The pci_alloc_irq_vectors_affinity() will always return
-ENOSPC on failure, when allocating MSI-X vectors only, whereas with MSI
fallback it will forward any error returned by __pci_enable_msi_range().
This is a confusing behaviour, so have the pci_alloc_irq_vectors_affinity()
forward the error code from __pci_enable_msix_range() when appropriate.

PCIBIOS_SUCCESSFUL (zero) or positive error values like
PCIBIOS_FUNC_NOT_SUPPORTED.
The PCIe capability accessors (pcie_capability_read_word(), et al)
similarly return PCIBIOS errors, but some callers assume they return
generic errno values like -EINVAL.
For example, the Myri-10G probe function returns a positive PCIBIOS error
if the pcie_capability_clear_and_set_word() in pcie_set_readrq() fails:
myri10ge_probe
status = pcie_set_readrq
return pcie_capability_clear_and_set_word
if (status)
return status
A positive return from a PCI driver probe function would cause a "Driver
probe function unexpectedly returned" warning from local_pci_probe()
instead of the desired probe failure.
Convert PCIBIOS errors to generic errno for all callers of:
pcie_capability_read_word
pcie_capability_read_dword
pcie_capability_write_word
pcie_capability_write_dword
pcie_capability_set_word
pcie_capability_set_dword
pcie_capability_clear_word
pcie_capability_clear_dword
pcie_capability_clear_and_set_word
pcie_capability_clear_and_set_dword
that check the return code for anything other than zero.

This reverts commit a43a67a2d7.
This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f644727 ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
