When a file is opened for writing, the vfs code (do_dentry_open)
calls get_write_access for the inode, thus incrementing the inode's write
count. That writer normally then creates a multi-block reservation for
the inode (i_res) that can be re-used by other writers, which speeds up
writes for applications that stupidly loop on open/write/close.
When the writes are all done, the multi-block reservation should be
deleted when the file is closed by the last "writer."
Commit 0ec9b9ea4f broke that concept when it moved the call to
gfs2_rs_delete before the check for FMODE_WRITE. Non-writers have no
business removing the multi-block reservations of writers. In fact, if
someone opens and closes the file for RO while a writer has a
multi-block reservation, the RO closer will delete the reservation
midway through the write, and this results in:
kernel BUG at fs/gfs2/rgrp.c:677! (or thereabouts) which is:
BUG_ON(rs->rs_requested); from function gfs2_rs_deltree.
This patch moves the check back inside the check for FMODE_WRITE.

If a call to re-create the auxiliary device happens in a context that has
already taken the RTNL lock, then the call flow that recreates auxiliary
device can hang if there is another attempt to claim the RTNL lock by the
auxiliary driver.
To avoid this, any call to re-create auxiliary devices that comes from
an source that is holding the RTNL lock (e.g. netdev notifier when
interface exits a bond) should execute in a separate thread. To
accomplish this, add a flag to the PF that will be evaluated in the
service task and dealt with there.

Currently, the same handler is called for both a NETDEV_BONDING_INFO
LAG unlink notification as for a NETDEV_UNREGISTER call. This is
causing a problem though, since the netdev_notifier_info passed has
a different structure depending on which event is passed. The problem
manifests as a call trace from a BUG: KASAN stack-out-of-bounds error.
Fix this by creating a handler specific to NETDEV_UNREGISTER that only
is passed valid elements in the netdev_notifier_info struct for the
NETDEV_UNREGISTER event.
Also included is the removal of an unbalanced dev_put on the peer_netdev

The driver was avoiding offload for IPIP (at least) frames due to
parsing the inner header offsets incorrectly when trying to check
lengths.
This length check works for VXLAN frames but fails on IPIP frames
because skb_transport_offset points to the inner header in IPIP
frames, which meant the subtraction of transport_header from
inner_network_header returns a negative value (-20).
With the code before this patch, everything continued to work, but GSO
was being used to segment, causing throughputs of 1.5Gb/s per thread.
After this patch, throughput is more like 10Gb/s per thread for IPIP
traffic.

Single page and coherent memory blocks can use different DMA masks
when the macb accesses physical memory directly. The kernel is clever
enough to allocate pages that fit into the requested address width.
When using the ARM SMMU, the DMA mask must be the same for single

tables turn into one big mess.

The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.

[Why]
pflip interrupt order are mapped 1 to 1 to otg id.
e.g. if irq_src=26 corresponds to otg0 then 27->otg1, 28->otg2...
Linux DM registers pflip interrupts per number of crtcs.
In fused pipe case crtc numbers can be less than otg id.
e.g. if one pipe out of 3(otg#0-2) is fused adev->mode_info.num_crtc=2
so DM only registers irq_src 26,27.
This is a bug since if pipe#2 remains unfused DM never gets
otg2 pflip interrupt (irq_src=28)
That may results in gfx failure due to pflip timeout.

The original version of the IORT PMCG definition had an oversight
wherein there was no way to describe the second register page for an
implementation using the recommended RELOC_CTRS feature. Although the
spec was fixed, and the final patches merged to ACPICA and Linux written
against the new version, it seems that some old firmware based on the
original revision has survived and turned up in the wild.
Add a check for the original PMCG definition, and avoid filling in the
second memory resource with nonsense if so. Otherwise it is likely that
something horrible will happen when the PMCG driver attempts to probe.
