[ Upstream commit ee1c71a8e1 ]
If the system has other devices being registered in the component
framework, the compare function will be called with a device that
doesn't belong to vimc.
This device is not necessarily a platform_device, nor have a
platform_data (which causes a NULL pointer dereference error) and if it
does have a pdata, it is not necessarily type of struct vimc_platform_data.
So casting to any of these types is wrong.
Instead of expecting a given pdev with a given pdata, just expect for
the device it self. vimc-core is the one who creates them, we know in
advance exactly which object to expect in the match.

[ Upstream commit 83d5782681 ]
The driver tries to periodically refresh neighbours that are used to
reach nexthops. This is done by periodically calling neigh_event_send().
However, if the neighbour becomes dead, there is nothing we can do to
return it to a connected state and the above function call is basically
a NOP.
This results in the nexthop never being written to the device's
adjacency table and therefore never used to forward packets.
Fix this by dropping our reference from the dead neighbour and
associating the nexthop with a new neigbhour which we will try to
refresh.

commit 60e4cf67a5 upstream.
Since commit d0a5b995a3 (vfs: Add IOP_XATTR inode operations flag)
extended attributes haven't worked on the root directory in reiserfs.
This is due to reiserfs conditionally setting the sb->s_xattrs handler
array depending on whether it located or create the internal privroot
directory. It necessarily does this after the root inode is already
read in. The IOP_XATTR flag is set during inode initialization, so
it never gets set on the root directory.
This commit unconditionally assigns sb->s_xattrs and clears IOP_XATTR on
internal inodes. The old return values due to the conditional assignment
are handled via open_xa_root, which now returns EOPNOTSUPP as the VFS
would have done.

commit b67a95f2ab upstream.
The PCI INTx interrupts and other LSI interrupts are handled differently
under a sPAPR platform. When the interrupt source characteristics are
queried, the hypervisor returns an H_INT_ESB flag to inform the OS
that it should be using the H_INT_ESB hcall for interrupt management
and not loads and stores on the interrupt ESB pages.
A default -1 value is returned for the addresses of the ESB pages. The
driver ignores this condition today and performs a bogus IO mapping.
Recent changes and the DEBUG_VM configuration option make the bug
visible with :

commit 1ca3dec2b2 upstream.
When the machine crash handler is invoked, all interrupts are masked
but interrupts which have not been started yet do not have an ESB page
mapped in the Linux address space. This crashes the 'crash kexec'
sequence on sPAPR guests.
To fix, force the mapping of the ESB page when an interrupt is being
mapped in the Linux IRQ number space. This is done by setting the
initial state of the interrupt to OFF which is not necessarily the
case on PowerNV.

commit f6498b922e upstream.
Pandora_wl1251_init_card was used to do special pdata based
setup of the sdio mmc interface. This does no longer work with
v4.7 and later. A fix requires a device tree based mmc3 setup.
Therefore we move the special setup to omap_hsmmc.c instead
of calling some pdata supplied init_card function.
The new code checks for a DT child node compatible to wl1251
so it will not affect other MMC3 use cases.
Generally, this code was and still is a hack and should be
moved to mmc core to e.g. read such properties from optional
DT child nodes.
