Physical sector size is supported in v1.2 of the vDisk protocol and
should be set if available. If protocol version 1.2 is used and the
physical disk size is unavailable, then the disk is considered busy.

When returning from the user probe code into userspace process, PC & NPC are
truncated to 32 bits.
Due to shared libraries getting loaded very high in the virtual address
space of
the process, placing a user probe inside a shared library makes the kernel
return into the process at the wrong address, causing it to seg'fault
most of
the time.
This patch prevents truncating PC and NPC.

The objects viking_ops, viking_sun4d_smp_ops and smp_cachetlb_ops of
type sparc32_cachetlb_ops are not modified anywhere after getting modified
in the init functions. Inside init their reference is also stored in a
pointer of type const struct sparc32_cachetlb_ops *. So these structures
are never modified after init, therefore add __ro_after to the declaration
of these structures.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Revisit warning logic when not applying default helper assignment.
Jiri Kosina considers we are breaking existing setups and not warning
our users accordinly now that automatic helper assignment has been
turned off by default. So let's make him happy by spotting the warning
by when we find a helper but we cannot attach, instead of warning on the
former deprecated behaviour. Patch from Jiri Kosina.
2) Two patches to fix regression in ctnetlink interfaces with
nfnetlink_queue. Specifically, perform more relaxed in CTA_STATUS
and do not bail out if CTA_HELP indicates the same helper that we
already have. Patches from Kevin Cernekee.
3) A couple of bugfixes for ipset via Jozsef Kadlecsik. Due to wrong
index logic in hash set types and null pointer exception in the
list:set type.
4) hashlimit bails out with correct userspace parameters due to wrong
arithmetics in the code that avoids "divide by zero" when
transforming the userspace timing in milliseconds to token credits.
Patch from Alban Browaeys.
5) Fix incorrect NFQA_VLAN_MAX definition, patch from
Ken-ichirou MATSUZAWA.
6) Don't not declare nfnetlink batch error list as static, since this
may be used by several subsystems at the same time. Patch from
Liping Zhang.

When creating EQs to handle CQ completion events for the PF
or for VFs, we create enough EQE entries to handle completions
for the max number of CQs that can use that EQ.
When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource tracker).
Therefore, when creating an EQ, the number of EQE entries that the VF
should request for that EQ is the CQ quota value (and not the total
number of CQs available in the FW).
Under SRIOV, the PF, also must use its CQ quota, because
the resource tracker also controls how many CQs the PF can obtain.
Using the FW total CQs instead of the CQ quota when creating EQs resulted
wasting MTT entries, due to allocating more EQEs than were needed.

probed PFs
In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.
log_num_mgm_entry_size is a global module parameter which
affects all ConnectX-3 PFs installed on that host.
If a VF changes log_num_mgm_entry_size, this will affect all PFs
which are probed subsequent to the change (by disabling DMFS for
those PFs).

Mellanox mlx5e fixes for 4.11-rc1
This series includes some important bug fixes for mlx5e driver.
Three misc fixes:
From Mohamad, compilation fix on s390 system
From Me, A fix for driver unload when switchdev mode is on.
From Tariq, HW LRO frag size optimization for when build_skb is not used
(striding RQ mode).
Three CQE compression related fixes:
Two fixes from Tariq and I, to correctly setup CQE compression
parameters on driver load and on arbitrary user modifications.
Last patch, fixes a very critical issue that was originally reported
by Tom, where the driver reported csum errors or even page ref issues
for when cqe compression is enabled and rapidly active.
For your convenience this series was generated on top of net-next branch:
005c3490e9db ('Revert "ath10k: Search SMBIOS for OEM board file extension"')
for -stable:
net/mlx5e: Register/unregister vport representors on interface (for kernel >= 4.9)
net/mlx5e: Do not reduce LRO WQE size when not using build_skb (for kernel >= 4.9)
net/mlx5e: Fix broken CQE compression initialization (for kernel >= 4.9)
net/mlx5e: Update MPWQE stride size when modifying CQE compress state (for kernel >= 4.7)
net/mlx5e: Fix wrong CQE decompression (for kernel >= 4.7)

In cqe compression with striding RQ, the decompression of the CQE field
wqe_counter was done with a wrong wraparound value.
This caused handling cqes with a wrong pointer to wqe (rx descriptor)
and creating SKBs with wrong data, pointing to wrong (and already consumed)
strides/pages.
The meaning of the CQE field wqe_counter in striding RQ holds the
stride index instead of the WQE index. Hence, when decompressing
a CQE, wqe_counter should have wrapped-around the number of strides
in a single multi-packet WQE.
We dropped this wrap-around mask at all in CQE decompression of striding
RQ. It is not needed as in such cases the CQE compression session would
break because of different value of wqe_id field, starting a new
compression session.
Tested:
ethtool -K ethxx lro off/on
ethtool --set-priv-flags ethxx rx_cqe_compress on
super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D
verified no csum errors and no page refcount issues.

When the admin enables/disables cqe compression, updating
mpwqe stride size is required:
CQE compress ON ==> stride size = 256B
CQE compress OFF ==> stride size = 64B
This is already done on driver load via mlx5e_set_rq_type_params, all we
need is just to call it on arbitrary admin changes of cqe compression
state via priv flags or when changing timestamping state
(as it is mutually exclusive with cqe compression).
This bug introduces no functional damage, it only makes cqe compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.
Tested:
ethtool --set-priv-flags ethxx rx_cqe_compress on
pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
verify `ethtool -S ethxx | grep compress` are advancing more often

Some of RQ type parameters are derived from CQE compression state flag,
CQE compression flag was initialized only after RQ type parameters
setup. This leads to load RQ with stride size smaller than what we
want for when CQE compression is on.
This bug introduces no functional damage, it only makes CQE compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.
Fix this by marking default status of CQE compression in PFLAG prior to
calling mlx5e_set_rq_priv_params(), as it inits some fields based on it.
Tested:
load driver on systems where rx CQE compress will be on (MH)
pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
verify `ethtool -S ethxx | grep compress` are advancing more often

Currently vport representors are added only on driver load and removed on
driver unload. Apparently we forgot to handle them when we added the
seamless reset flow feature. This caused to leave the representors
netdevs alive and active with open HW resources on pci shutdown and on
error reset flows.
To overcome this we move their handling to interface attach/detach, so
they would be cleaned up on shutdown and recreated on reset flows.

Pull KVM updates from Paolo Bonzini:
"4.11 is going to be a relatively large release for KVM, with a little
over 200 commits and noteworthy changes for most architectures.
ARM:
- GICv3 save/restore
- cache flushing fixes
- working MSI injection for GICv3 ITS
- physical timer emulation
MIPS:
- various improvements under the hood
- support for SMP guests
- a large rewrite of MMU emulation. KVM MIPS can now use MMU
notifiers to support copy-on-write, KSM, idle page tracking,
swapping, ballooning and everything else. KVM_CAP_READONLY_MEM is
also supported, so that writes to some memory regions can be
treated as MMIO. The new MMU also paves the way for hardware
virtualization support.
PPC:
- support for POWER9 using the radix-tree MMU for host and guest
- resizable hashed page table
- bugfixes.
s390:
- expose more features to the guest
- more SIMD extensions
- instruction execution protection
- ESOP2
x86:
- improved hashing in the MMU
- faster PageLRU tracking for Intel CPUs without EPT A/D bits
- some refactoring of nested VMX entry/exit code, preparing for live
migration support of nested hypervisors
- expose yet another AVX512 CPUID bit
- host-to-guest PTP support
- refactoring of interrupt injection, with some optimizations thrown
in and some duct tape removed.
- remove lazy FPU handling
- optimizations of user-mode exits
- optimizations of vcpu_is_preempted() for KVM guests
generic:
- alternative signaling mechanism that doesn't pound on
tsk->sighand->siglock"

imx-drm: TVE regulator, fb size limit, and ipu-v3 module fixes
- Fix i.MX5 TV encoder probing in case no dac-supply regulator
is set in the device tree.

Pull printk updates from Petr Mladek:
- Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven
Rostedt as the printk reviewer. This idea came up after the
discussion about printk issues at Kernel Summit. It was formulated
and discussed at lkml[1].
- Extend a lock-less NMI per-cpu buffers idea to handle recursive
printk() calls by Sergey Senozhatsky[2]. It is the first step in
sanitizing printk as discussed at Kernel Summit.
The change allows to see messages that would normally get ignored or
would cause a deadlock.
Also it allows to enable lockdep in printk(). This already paid off.
The testing in linux-next helped to discover two old problems that
were hidden before[3][4].
- Remove unused parameter by Sergey Senozhatsky. Clean up after a past
change.

At present, Tying the first_num size to NCHUNKS_ORDER is confusing. the
number of chunks is completely unrelated to the number of buddies.
The patch limits the first_num to actual range of possible buddy indexes.
and that is more reasonable and obvious without functional change.

We had a deprecated_attr_warn() warning for 2 years and now the time has
come and we finally can do the cleanup.
The plan was as follows:
: per-stat sysfs attributes are considered to be deprecated.
: The basic strategy is:
: -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11)
: -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11)
:
: The list of deprecated attributes can be found here:
: Documentation/ABI/obsolete/sysfs-block-zram
:
: Basically, every attribute that has its own read accessible sysfs
: node (e.g. num_reads) *AND* is accessible via one of the stat files
: (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered
: to be deprecated.
The patch also removes `obsolete/sysfs-block-zram', clean ups
`testing/sysfs-block-zram' and tweaks zram.txt files.

This patch also cleans up the type casting for phys_addr_t by using %pa

Logic on whether we can reap pages from the VMA should match what we
have in madvise_dontneed(). In particular, we should skip, VM_PFNMAP
VMAs, but we don't now.
Let's just extract condition on which we can shoot down pagesi from a
VMA with MADV_DONTNEED into separate function and use it in both places.
