->Stop the ep timer after MPA negotiation so that the arp failures
during send_mpa_reply/reject will be handled by process_timeout() after
the ep timer expires.
->Added case MPA_REP_SENT in process_timeout().
->For MPA reject, c4iw_ep_disconnect tries to start an already started
timer, which leads to warning message "timer already started".
-> In case of mpa reject stop the timer and call send_mpa_reject().
-> Added new ep flag STOP_MPA_TIMER to tell fw4_ack() to stop the timer
only for send_mpa_reply(), which is set in c4iw_accept_cr().

The FID value in a ULP_MEMIO command needs to be set to an IQ ID of
a queue configured for our PF. The FID/IQ id is used to index into the
PCIE FID table, to find out on which function the DMA needs to be
issued. Essentially, every DMA needs to have the ingress queue. The exact
ingress queue doesn't matter, but it needs to be an ingress queue
associated with the function you want to see the DMA on.

Pull cgroup fixes from Tejun Heo:
"During v4.6-rc1 cgroup namespace support was merged. There is an
issue where it's impossible to tell whether a given cgroup mount point
is bind mounted or namespaced. Serge has been working on the issue
but it took longer than expected to resolve, so the late pull request.
Given that it's a completely new feature and the patches don't touch

retrying for v4.7"

The e1000e_config_hwtstamp function was incorrectly resetting the SYSTIM
registers every time the ioctl was being run. If you happened to be
running ptp4l and lost the PTP connect (removing cable, or blocking the
UDP traffic for example), then ptp4l will eventually perform a restart
which involves re-requesting timestamp settings. In e1000e this has the
unfortunate and incorrect result of resetting SYSTIME to the kernel
time. Since kernel time is usually in UTC, and PTP time is in TAI, this
results in the leap second being re-applied.
Fix this by extracting the SYSTIME reset out into its own function,
e1000e_ptp_reset, which we call during reset to restore the hardware
registers. This function will (a) restart the timecounter based on the
new system time, (b) restore the previous PPB setting, and (c) restore
the previous hwtstamp settings.
In order to perform (b), I had to modify the adjfreq ptp function
pointer to store the old delta each time it is called. This also has the
side effect of restoring the correct base timinca register correctly.
The driver does not need to explicitly zero the ptp_delta variable since
the entire adapter structure comes zero-initialized.

This patch adds support for partial GSO segmentation in the case of
tunnels. Specifically with this change the driver an perform segmentation
as long as the frame either has IPv6 inner headers, or we are allowed to
mangle the IP IDs on the inner header. This is needed because we will not
be modifying any fields from the start of the start of the outer transport
header to the start of the inner transport header as we are treating them
like they are just a block of IP options.

A recent patch added a stub function for acpi_video_get_levels when
CONFIG_ACPI_VIDEO is disabled. However, this is marked as 'static'

SYSTIMH:SYSTIML registers are incremented by 24-bit value TIMINCA[23..0]
er32(SYSTIML) are probably moderately expensive (they are pci bus reads).
Can we avoid one of them? Yes, we can.
If the SYSTIML value we see is smaller than 0xff000000, the overflow
into SYSTIMH would require at least two increments.
We do two reads, er32(SYSTIML) and er32(SYSTIMH), in this order.
Even if one increment happens between them, the overflow into SYSTIMH
is impossible, and we can avoid doing another er32(SYSTIML) read
and overflow check.

If two consecutive reads of the counter are the same, it is also
not an overflow. "systimel_1 < systimel_2" should be
"systimel_1 <= systimel_2".
Before the patch, we could perform an *erroneous* correction:
Let's say that systimel_1 == systimel_2 == 0xffffffff.
"systimel_1 < systimel_2" is false, we think it's an overflow,
we read "systimeh = er32(SYSTIMH)" which meanwhile had incremented,
and use "(systimeh << 32) + systimel_2" value which is 2^32 too large.

The genvdso program modifies the debug and stripped versions of the
VDSOs in place, and errors if the modification has already taken place.
Unfortunately this means that a rebuild which tries to rerun genvdso to
generate vdso*-image.c without also rebuilding vdso.so.dbg (for example
if genvdso.c is modified) hits a build error like this:
arch/mips/vdso/genvdso 'arch/mips/vdso/vdso.so.dbg' already contains a '.MIPS.abiflags' section
This is fixed by reorganising the rules such that unmodified .so files
have a .raw suffix, and these are copied in the same rule that runs
genvdso on the copies.
I.e. previously we had:
cmd_vdsold:
link objects -> vdso.so.dbg
cmd_genvdso:
strip vdso.so.dbg -> vdso.so
run genvdso -> vdso-image.c
and modify vdso.so.dbg and vdso.so in place
Now we have:
cmd_vdsold:
link objects -> vdso.so.dbg.raw
a new cmd_objcopy based strip rule (inspired by ARM):
strip vdso.so.dbg.raw -> vdso.so.raw
cmd_genvdso:
copy vdso.so.dbg.raw -> vdso.so.dbg
copy vdso.so.raw -> vdso.so
run genvdso -> vdso-image.c
and modify vdso.so.dbg and vdso.so in place

If the size passed to ring_buffer_resize() is greater than MAX_LONG - BUF_PAGE_SIZE
then the DIV_ROUND_UP() will return zero.
Here's the details:
# echo 18014398509481980 > /sys/kernel/debug/tracing/buffer_size_kb
tracing_entries_write() processes this and converts kb to bytes.
18014398509481980 << 10 = 18446744073709547520
and this is passed to ring_buffer_resize() as unsigned long size.
size = DIV_ROUND_UP(size, BUF_PAGE_SIZE);
Where DIV_ROUND_UP(a, b) is (a + b - 1)/b
BUF_PAGE_SIZE is 4080 and here
18446744073709547520 + 4080 - 1 = 18446744073709551599
where 18446744073709551599 is still smaller than 2^64
2^64 - 18446744073709551599 = 17
But now 18446744073709551599 / 4080 = 4521260802379792
and size = size * 4080 = 18446744073709551360
This is checked to make sure its still greater than 2 * 4080,
which it is.
Then we convert to the number of buffer pages needed.
nr_page = DIV_ROUND_UP(size, BUF_PAGE_SIZE)
but this time size is 18446744073709551360 and
2^64 - (18446744073709551360 + 4080 - 1) = -3823
Thus it overflows and the resulting number is less than 4080, which makes
3823 / 4080 = 0
an nr_pages is set to this. As we already checked against the minimum that
nr_pages may be, this causes the logic to fail as well, and we crash the
kernel.
There's no reason to have the two DIV_ROUND_UP() (that's just result of
historical code changes), clean up the code and fix this bug.

An xdr_buf has a head, a vector of pages, and a tail. Each
RPC request is presented to the NFS server contained in an
xdr_buf.
The RDMA transport would like to supply the NFS server with only
the NFS WRITE payload bytes in the page vector. In some common
cases, that would allow the NFS server to swap those pages right
into the target file's page cache.
Have the transport's RDMA Read logic put XDR pad bytes in the tail
iovec, and not in the pages that hold the data payload.
The NFSv3 WRITE XDR decoder is finicky about the lengths involved,
so make sure it is looking in the correct places when computing
the total length of the incoming NFS WRITE request.
