During the development of the GICv3/v4 architecture, it was
envisaged to have a CPU table, though the use for it was
never completely clear (the collection table serves that role
pretty well). It ended being dropped before the specification
was published, though it lived on in the driver.
In order to avoid people scratching their head too much, let's do
the same in the kernel.

With many drivers converting to using generic device properties, it is
useful to provide array of device properties when instantiating new i2c
client via i2c_board_info and have them automatically added to the device

For the benefit of drivers that rebuild IEs in firmware, parse the

The current code uses the CLOCKSOURCE_OF_DECLARE macro to fill the clksrc
table with a t-uple (name, init_function).
Unfortunately it ends up to the clockevent and the clocksource being
both initialized with this macro. It is not a problem by itself but there
is not a clear distinction between a clockevent and a clocksource in the
code initialization path. Somebody can argue there are the same IP block
and the same DT node. But conceptually from the software side, there are
two distincts entities and as is they should be initialized separetely.
Some drivers which do not have a clocksource end up by using the
CLOCKSOURCE_OF_DECLARE macro to declare a clockevent.
Another result is the fuzzy organization in the clocksource directory,
where the clockevents are implemented in the same file than the
clocksources or file labelled timer-something implementing a clocksource.
This patch provides another macro to specifically declare a clockevent in
the same way than the clocksource and gives the opportunity to write two
separate drivers, one for the clocksource and another for the clockevents.
Hopefully, that can help to do some housework in the directory, perhaps
split the drivers in to entities, for example:
- clksrc-rockchip.c
- clkevt-rockchip.c
Also, it gives the possibility to declare clocksources separately in the
DT and then use a clocksource from IP block while while clockevents are
used from another IP block.

__packed is considered harmful as it potentially generates code that
doesn't perform well and its usage should be avoided as much as
possible.
This patch drops __packed from all SCTP structures except one, which is
sctp_signed_cookie. In there it's required, as per changelog on
commit 9834a2bb4970 ("[SCTP]: Fix sctp_cookie alignment in the packet.").
After this patch, no alignment changes neither in x86 or x86_64 and
no exceptions were noticed during testing on both archs.
Code size for SCTP module also didn't change with this patch.

====================
mlx5-updates-2017-01-31
This series includes some updates to mlx5 core and ethernet driver.
We got one patch from Or to fix some static checker warnings.
2nd patche from Dan came to add the support for 128B cache line
in the HCA, which will configures the hardware to use 128B alignment only
on systems with 128B cache lines, otherwise it will be kept as the current
default of 64B.
From me three patches to support no inline copy on TX on ConnectX-5 and
later HCAs. Starting with two small infrastructure changes and
refactoring patches followed by two patches to add the actual support for
both xmit ndo and XDP xmit routines.
Last patch is a simple fix to return a mistakenly removed pointer from the
SQ structure, which was remove in previous submission of mlx5 4K UAR.

For XDP we will need to reset the queues to allow for buffer headroom
to be configured. In order to do this we need to essentially run the
freeze()/restore() code path. Unfortunately the locking requirements
between the freeze/restore and reset paths are different however so
we can not simply reuse the code.
This patch refactors the code path and adds a reset helper routine.

We may or may not have all possible CPUs in MADT on boot but in any
case we're overwriting x86_cpu_to_acpiid mapping with U32_MAX when
acpi_register_lapic() is called again on the CPU hotplug path:
acpi_processor_hotadd_init()
-> acpi_map_cpu()
-> acpi_register_lapic()
As we have the required acpi_id information in acpi_processor_hotadd_init()
propagate it to acpi_map_cpu() to always keep x86_cpu_to_acpiid
mapping valid.

When augmenting ACPI-enumerated devices with additional property data based
on DMI info, a module has often several potential property sets, with only
one being active on a given box. In order to save memory it should be
possible to mark everything and __initdata or __initconst, execute DMI
match early, and duplicate relevant properties. Then kernel will discard

Get the firmware's secure-boot status in the kernel boot wrapper and stash
it somewhere that the main kernel image can find.
The efi_get_secureboot() function is extracted from the ARM stub and (a)
generalised so that it can be called from x86 and (b) made to use
efi_call_runtime() so that it can be run in mixed-mode.
For x86, it is stored in boot_params and can be overridden by the boot
loader or kexec. This allows secure-boot mode to be passed on to a new
kernel.

Previously, each filesystem configured without encryption support would
define all the public fscrypt functions to their notsupp_* stubs. This
list of #defines had to be updated in every filesystem whenever a change
was made to the public fscrypt functions. To make things more
maintainable now that we have three filesystems using fscrypt, split the
old header fscrypto.h into several new headers. fscrypt_supp.h contains
the real declarations and is included by filesystems when configured
with encryption support, whereas fscrypt_notsupp.h contains the inline
stubs and is included by filesystems when configured without encryption
support. fscrypt_common.h contains common declarations needed by both.

There is a hardware feature that will pad the start or end of a DMA to
be cache line aligned to avoid RMWs on the last cache line. The default
cache line size setting for this feature is 64B. This change configures
the hardware to use 128B alignment on systems with 128B cache lines.
In addition we lower bound MPWRQ stride by HCA cacheline in mlx5e,
MPWRQ stride should be at least the HCA cacheline, the current default
is 64B and in case HCA_CAP.cach_line_128byte capability is set, MPWRQ RX
stride will automatically be aligned to 128B.

Some CAN controllers don't implement a FIFO in hardware, but fill their
mailboxes in a particular order (from lowest to highest or highest to lowest).
This makes problems to read the frames in the correct order from the hardware,
as new frames might be filled into just read (low) mailboxes. This gets worse,
when following new frames are received into not read (higher) mailboxes.
On the bright side some these CAN controllers put a timestamp on each received
CAN frame. This patch adds support to offload CAN frames in interrupt context,
order them by timestamp and then transmitted in a NAPI context.

Back when this was first written, dma_supported() was somewhat of a
murky mess, with subtly different interpretations being relied upon in
various places. The "does device X support DMA to address range Y?"
uses assuming Y to be physical addresses, which motivated the current
iommu_dma_supported() implementation and are alluded to in the comment
therein, have since been cleaned up, leaving only the far less ambiguous
"can device X drive address bits Y" usage internal to DMA API mask
setting. As such, there is no reason to keep a slightly misleading
callback which does nothing but duplicate the current default behaviour;
we already constrain IOVA allocations to the iommu_domain aperture where
necessary, so let's leave DMA mask business to architecture-specific
code where it belongs.

running APIC timer) feature and with fairly large number of CPUs as
well as CPUs coming in and out of intel_idle frequently, the lock
contention on the tick_broadcast_lock can become significant.
To reduce contention, the lock is put into its own cacheline and all
the cpumask_var_t variables are put into the __read_mostly section.
Running the SP benchmark of the NAS Parallel Benchmarks on a 4-socket
16-core 32-thread Nehalam system, the performance number improved
from 3353.94 Mop/s to 3469.31 Mop/s when this patch was applied on

BUG: unable to handle kernel paging request at ffffea017a000000
IP: show_valid_zones+0x6f/0x160
This issue may happen on x86-64 systems with 64GiB or more memory since
their memory block size is bumped up to 2GiB. [1] An example of such
systems is desribed below. 0x3240000000 is only aligned by 1GiB and
this memory block starts from 0x3200000000, which is not backed by

Since test_pages_in_a_zone() already checks holes, fix this issue by
extending this function to return 'valid_start' and 'valid_end' for a
given range. show_valid_zones() then proceeds with the valid range.

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree, they are:
1) Stash ctinfo 3-bit field into pointer to nf_conntrack object from
sk_buff so we only access one single cacheline in the conntrack
hotpath. Patchset from Florian Westphal.
2) Don't leak pointer to internal structures when exporting x_tables
ruleset back to userspace, from Willem DeBruijn. This includes new
helper functions to copy data to userspace such as xt_data_to_user()
as well as conversions of our ip_tables, ip6_tables and arp_tables
clients to use it. Not surprinsingly, ebtables requires an ad-hoc
update. There is also a new field in x_tables extensions to indicate
the amount of bytes that we copy to userspace.
3) Add nf_log_all_netns sysctl: This new knob allows you to enable
logging via nf_log infrastructure for all existing netnamespaces.
Given the effort to provide pernet syslog has been discontinued,
let's provide a way to restore logging using netfilter kernel logging
facilities in trusted environments. Patch from Michal Kubecek.
4) Validate SCTP checksum from conntrack helper, from Davide Caratti.
5) Merge UDPlite conntrack and NAT helpers into UDP, this was mostly
a copy&paste from the original helper, from Florian Westphal.
6) Reset netfilter state when duplicating packets, also from Florian.
7) Remove unnecessary check for broadcast in IPv6 in pkttype match and
nft_meta, from Liping Zhang.
8) Add missing code to deal with loopback packets from nft_meta when
used by the netdev family, also from Liping.
9) Several cleanups on nf_tables, one to remove unnecessary check from
the netlink control plane path to add table, set and stateful objects
and code consolidation when unregister chain hooks, from Gao Feng.
10) Fix harmless reference counter underflow in IPVS that, however,
results in problems with the introduction of the new refcount_t
type, from David Windsor.
11) Enable LIBCRC32C from nf_ct_sctp instead of nf_nat_sctp,
from Davide Caratti.
12) Missing documentation on nf_tables uapi header, from Liping Zhang.
13) Use rb_entry() helper in xt_connlimit, from Geliang Tang.

areas. Priority order in an array matters, however order of items inside
a priority group does not matter.
As an initial implementation, L-sort algorithm is used. It is quite
trivial. More advanced algorithm called P-sort will be introduced as a
follow-up. The infrastructure is prepared for other algos.
Alongside this, a testing module is introduced as well.

Steven suggested to improve trace_print_hex_seq() a bit after commit
2acae0d5b0f7 ("trace: add variant without spacing in trace_print_hex_seq")
in two ways: i) by adding a kdoc comment for the helper function
itself and ii) by renaming 'spacing' argument into 'concatenate'
to better denote that we don't add spaces between each hex bytes.

New nested netlink attribute to associate tunnel info per vlan.
This is used by bridge driver to send tunnel metadata to
bridge ports in vlan tunnel mode. This patch also adds new per
port flag IFLA_BRPORT_VLAN_TUNNEL to enable vlan tunnel mode.
off by default.
One example use for this is a vxlan bridging gateway or vtep
which maps vlans to vn-segments (or vnis). User can configure
per-vlan tunnel information which the bridge driver can use
to bridge vlan into the corresponding vn-segment.

This patch adds a Qualcomm specific quirk to the arm_smccc_smc call.
On Qualcomm ARM64 platforms, the SMC call can return before it has
completed. If this occurs, the call can be restarted, but it requires
using the returned session ID value from the interrupted SMC call.
The quirk stores off the session ID from the interrupted call in the
quirk structure so that it can be used by the caller.
This patch folds in a fix given by Sricharan R:

This patch adds a quirk parameter to the arm_smccc_(smc/hvc) calls.
The quirk structure allows for specialized SMC operations due to SoC
specific requirements. The current arm_smccc_(smc/hvc) is renamed and
macros are used instead to specify the standard arm_smccc_(smc/hvc) or
the arm_smccc_(smc/hvc)_quirk function.
This patch and partial implementation was suggested by Will Deacon.
