sunvnet - add missing rmb() for sunvnet driver
The sunvnet driver does not have an rmb() in the ring consumer corresponding
to the wmb() in the producer. According to Documentation/memory-barriers.txt:
"When dealing with CPU-CPU interactions, certain types of memory barrier should
always be paired. A lack of appropriate pairing is almost certainly an error."
In cases where an rmb() is not a no-op and a consumer is removing data from
the ring while a producer is adding new entries, a load reorder would allow
CPU1 CPU2
---- ----
LOAD desc.size [e.g]
STORE desc.size
<wmb>
set desc.hdr.state = VIO_DESC_READY
LOAD desc.hdr.state
[because VIO_DESC_READY, use
old desc.size, already loaded
out of order]
[CPU2 has reordered apparently unrelated LOADs]
To ensure other desc fields are not loaded before checking VIO_DESC_READY, we
need an rmb() between the check and desc data accesses.
I've also moved the viodbg() call to after the rmb() so that it, too, has
current descriptor data even with reordering, which has the side effect that
it won't print anything for descriptors that are not VIO_DESC_READY as before.
That's a) probably a good thing, since the fields are not necessarily set and,
b) better than adding another rmb() just for viodbg().
This would not be possible if strict-ordering is enforced, but then the
memory barriers should be no-ops in that case.

timekeeping: Update timekeeper before updating vsyscall and pvclock
The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.
The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.
commit cbcf2dd3b3d4 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.

Otherwise we could end up in TX frames being sent but not

bogus pointer deference in nommu_map_page.
The fix is pretty easy, if we convert the 3c59x driver to use the more
convieient skb_frag_dma_map api we don't need to find the virtual address of the
page at all, and page gets mapped to the hardware properly. Verified to fix the
problem as described by the reporter.
Applies to the net tree

v2) Converted PCI_DMA_TODEVICE to DMA_TO_DEVICE. Thanks Dave!

net-timestamp: only report sw timestamp if reporting bit is set
The timestamping API has separate bits for generating and reporting
timestamps. A software timestamp should only be reported for a packet
when the packet has the relevant generation flag (SKBTX_..) set
and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.
The second check was accidentally removed. Reinstitute the original
behavior.
Tested:
Without this patch, Documentation/networking/txtimestamp reports
timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
After the patch, it only reports them when the flag is set.

the file system's remount_fs()"), all file systems that have dirty data
to be written out need to call sync_filesystem() from their

ARM: edma: Fix configuration parsing for SoCs with multiple eDMA3 CC
DRA7 evm REV G and later boards uses a vtt regulator for DDR3
termination and this is controlled by gpio7_11. This gpio is
configured in boot loader. gpio7_11, which is only available only on
Pad A22, in previous boards, is connected only to an unused pad on
expansion connector EXP_P3 and is safe to be muxed as GPIO on all
DRA7-evm versions (without a need to spin off another dts file).
Since gpio7_11 is used to control VTT and should not be reset or kept
in idle state during boot up else VTT will be disconnected and DDR
gets corrupted. So, as part of this change, mark gpio7 as no-reset and
no-idle on init.
