Reset gpio is optional and it does not have to be defined for all boards.
So in mvebu_pcie_powerdown() like in mvebu_pcie_powerup() check that reset
gpio is defined prior usage to prevent NULL pointer dereference.

Here's a set of patches that adds a system call, fsinfo(), that allows
information about the VFS, mount topology, superblock and files to be
retrieved.
The patchset is based on top of the notifications patchset and allows event
counters implemented in the latter to be retrieved to allow overruns
Introduce an (effectively) non-repeating system-unique superblock ID that
can be used to determine that two objects are in the same superblock
without needing to worry about the ID changing in the meantime (as is
possible with device IDs).
The counter could also be used to tag other features, such
Add a system call to allow filesystem information to be queried. A request
value can be given to indicate the desired attribute. Support is provided
for enumerating multi-value attributes.

The new system call looks like:
int ret = fsinfo(
Provide a bitmap of features that a filesystem may provide for the path
being queried. Features include such things as:
(1) The general class of filesystem, such as kernel-interface,
block-based, flash-based, network-based.
(2) Supported inode features, such as which timestamps are suppor
Allow the fsinfo() syscall to look up a mount object by ID rather than by
pathname. This is necessary as there can be multiple mounts stacked up at
the same pathname and there's no way to look through them otherwise.
This is done by passing FSINFO_FLAGS_QUERY_MOUNT to fsinfo() in the
parameters a
Add a uniquifier ID to struct mount that is effectively unique over the
kernel lifetime to deal around mnt_id values being reused. This can then
be exported through fsinfo() to allow detection of replacement mounts that
happen to end up with the same mount ID.
The normal mount handle is still use
Provide fsinfo() attributes to retrieve superblock device name, options,
and statistics in string form. The following attributes are defined:
FSINFO_ATTR_SOURCE - Mount-specific device name
FSINFO_ATTR_CONFIGURATION - Mount options
FSINFO_ATTR_FS_STATIST
Allow mount information, including information about a mount object to be
queried with the fsinfo() system call. Setting FSINFO_FLAGS_QUERY_MOUNT
allows overlapping mounts to be queried by indicating that the syscall
should interpret the pathname as a number indicating the mount ID.
To this end,
Implement a program to demonstrate mount listing using the new fsinfo()
syscall. For example, to dump the tree from mount 21:
# ./test-mntinfo -m 21
MOUNTMOUNT ID CHANGE# AT P DEV TYPE
-- -- - -
21
Add a couple of attributes to allow information about the mount topology
and propagation to be retrieved:
(1) FSINFO_ATTR_MOUNT_TOPOLOGY.
Information about a mount's parentage in the mount topology tree and
its propagation attributes.
This has to be collected with the VFS namespa
Add fsinfo support to the AFS filesystem. This allows the export of server
lists, amongst other things, which is necessary to implement some of the
AFS 'fs' command set, such as "checkservers", "getserverprefs" and
"whereis".

Provide support for the handling of an overrun in a watch queue. In the
event that an overrun occurs, the watcher needs to be able to find out what
it was that they missed. To this end, previous patches added event
counters to struct mount.
To make them accessible, they can be retrieved using fs

Add a new "error_state" struct to fsinfo, and teach the kernel to fill
that out from sb->s_wb_err. There are two fields:
wb_error_last: the most recently recorded errno for the filesystem
wb_error_cookie: this value will change vs. the previously fetched

Yes, the iommu is an interesting case, and the current code is
wrong for that. Can you try the patch below? It contains a modified
version of Nicolas' patch to try CMA again for the expansion and a new
(for now hackish) way to not apply the addressability check for dma-iommu

ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely
wireless SMB deployment.
Prestera Switchdev is a firmware based driver that operates via PCI bus. The

The following features are supported:
- VLAN-aware bridge offloading
- VLAN-unaware bridge offloading
- FDB offloading (learning, ageing)
- Switchport configuration
Currently there are some limitations like:
- Only 1 VLAN-aware bridge instance supported
- FDB ageing timeo

Add PCI interface driver for Prestera Switch ASICs family devices, which
provides:
- Firmware loading mechanism
- Requests & events handling to/from the firmware
- Access to the firmware on the bus level
The firmware has to be loaded each time device is reset. The driver is
loading it
The ethtool API provides support for the configuration of the following
features: speed and duplex, auto-negotiation, MDI-x, forward error
correction, port media type. The API also provides information about the
port status, hardware and software statistic. The following limitation

There was a comment that still referenced the old x86-specific API

When get the pending softirqs, it need to process all the pending
softirqs in the while loop. If the processing time of each pending
softirq is need more than 2 msec in this loop, or one of the softirq
will running a long time, according to the original code logic, it
will process

Ah, okay. I've long lost track of how the tool works :/
