In commit bbc4e7d273 ("i40e: fix race condition with PTP_TX_IN_PROGRESS
bits") we modified the code which handles Tx timestamps so that we would
clear the progress bit as soon as possible.
A later commit 0bc0706b46 ("i40e: check for Tx timestamp timeouts during
watchdog") introduced similar code for detecting and handling cleanup of
a blocked Tx timestamp. This code did not use the same pattern for cleaning
up the skb.
Update this code to wait to free the skb until after the bit lock is
free, by first setting the ptp_tx_skb to NULL and clearing the lock.

We don't really need to have separate definitions for MAX_QUEUES and
I40EVF_MAX_REQ_QUEUES, since we'll always be limited by how many queues
we request anyways. If we haven't enabled requesting the maximum number
of queues, there's no reason to have our call to alloc_etherdev_mq
actually pass the higher value, since we'd never enable those queues
anyways.

The pfc related priority stats are already handled separately as these
stats are actually arrays of length I40E_MAX_USER_PRIORITY. Thus,
including them within i40e_gstrings_stats will just duplicate data.
Worse, the sizeof will be incorrect, as it will be the total size of the
stat arrays, which in this case is 8 * sizeof(u64), so we will only copy
the stat contents as if they were a u32.
Since we already correctly handle these stats else where, remove them
from the i40e_gstrings_stats.

When application fails to pass flags in netlink TLV when replacing
existing skbmod action, the kernel will leak refcnt:
$ tc actions get action skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 1 bind 0
For example, at this point a buggy application replaces the action with
index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
however refcnt gets bumped:
$ tc actions get actions skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55

There is not a way to differentiate these parts from the

to indicate which phy mode is required. Or the part can be

Calling the variable l3edev was relevant when neighbor lookup was the
last stage in the simulated pipeline. Now that mlxsw handles bridges and
vlan devices as well, calling it "L3" is a misnomer.
Thus in mlxsw_sp_span_dmac(), rename to "dev", because that function is
just a service routine where the distinction between tunnel and egress
device isn't necessary.
In mlxsw_sp_span_entry_tunnel_parms_common(), rename to "edev" to
emphasize that the routine traces packet egress.

David Howells says:
====================
rxrpc: Fixes
Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:
(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.

Commit 0fa1c57934 ("of/fdt: use memblock_virt_alloc for early alloc")
inadvertently switched the DT unflattening allocations from memblock to
bootmem which doesn't work because the unflattening happens before
bootmem is initialized. Swapping the order of bootmem init and
unflattening could also fix this, but removing bootmem is desired. So
enable NO_BOOTMEM on SH like other architectures have done.

The internal VM "mmap()" interfaces are based on the mmap target doing
everything using page indexes rather than byte offsets, because
traditionally (ie 32-bit) we had the situation that the byte offset
didn't fit in a register. So while the mmap virtual address was limited
by the word size of the architecture, the backing store was not.
So we're basically passing "pgoff" around as a page index, in order to
be able to describe backing store locations that are much bigger than
the word size (think files larger than 4GB etc).
But while this all makes a ton of sense conceptually, we've been dogged
by various drivers that don't really understand this, and internally
work with byte offsets, and then try to work with the page index by
turning it into a byte offset with "pgoff << PAGE_SHIFT".
Which obviously can overflow.
Adding the size of the mapping to it to get the byte offset of the end
of the backing store just exacerbates the problem, and if you then use
this overflow-prone value to check various limits of your device driver
mmap capability, you're just setting yourself up for problems.
The correct thing for drivers to do is to do their limit math in page
indices, the way the interface is designed. Because the generic mmap
code _does_ test that the index doesn't overflow, since that's what the
mmap code really cares about.
HOWEVER.
Finding and fixing various random drivers is a sisyphean task, so let's
just see if we can just make the core mmap() code do the limiting for
us. Realistically, the only "big" backing stores we need to care about
are regular files and block devices, both of which are known to do this
properly, and which have nice well-defined limits for how much data they
can access.
So let's special-case just those two known cases, and then limit other
random mmap users to a backing store that still fits in "unsigned long".
Realistically, that's not much of a limit at all on 64-bit, and on
32-bit architectures the only worry might be the GPU drivers, which can
have big physical address spaces.
To make it possible for drivers like that to say that they are 64-bit
clean, this patch does repurpose the "FMODE_UNSIGNED_OFFSET" bit in the
file flags to allow drivers to mark their file descriptors as safe in
the full 64-bit mmap address space.
[ The timing for doing this is less than optimal, and this should really
go in a merge window. But realistically, this needs wide testing more
than it needs anything else, and being main-line is the only way to do
that.
So the earlier the better, even if it's outside the proper development
cycle - Linus ]

linux-4.16 got support for softirq based hrtimers.
TCP can switch its pacing hrtimer to this variant, since this
avoids going through a tasklet and some atomic operations.
pacing timer logic looks like other (jiffies based) tcp timers.
v2: use hrtimer_try_to_cancel() in tcp_clear_xmit_timers()
to correctly release reference on socket if needed.
