Pull sparc updates from David Miller:
"Some 32-bit kgdb cleanups from Sam Ravnborg, and a hugepage TLB flush
overhead fix on 64-bit from Nitin Gupta"
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Reduce TLB flushes during hugepte changes
aeroflex/greth: fix warning about unused variable
openprom: fix warning
sparc32: drop superfluous cast in calls to __nocache_pa()
sparc32: fix build with STRICT_MM_TYPECHECKS
sparc32: use proper prototype for trapbase
sparc32: drop local prototype in kgdb_32
sparc32: drop hardcoding trap_level in kgdb_trap
I'm looking at trying to possibly merge the 32-bit and 64-bit versions
of the x86 uaccess.h implementation, but first this needs to be cleaned
up.
For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly
the special cases for the constant size, and it's actually never
relevant. Every user except for one aren't actually using a constant
size anyway, and the one user that uses it is better off just using
__put_user() instead.
So get rid of the unnecessary complexity.
[ The same cleanup should likely happen to __copy_from_user_inatomic()
as well, but that one has a lot more users that I need to take a look
at first ]

This module is loaded by the related mfd driver which has
the needed MODULE_DEVICE_TABLE(i2c,...).
This patch fix the modalias when the rtc driver is built
as a module, so the right name is used.
Everything operates correctly when this module is builtin.

The added support for SPI mode made it possible to configure the driver
when I2C is disabled, leaving an unused device table:
drivers/rtc/rtc-rv3029c2.c:794:29: error: 'rv3029_id' defined but not used [-Werror=unused-variable]
This moves the table inside of the #ifdef section that has the

The RTC RV3029 handles different types of alarms : seconds, minutes, ...
These alarms can be enabled or disabled individually using an AE_x bit
which is the last bit (BIT(7)) on each alarm registers.
To prepare the alarm IRQ support, the current code enables all the alarm
types by setting each AE_x to 1.
It also fixes others alarms issues :
- month and weekday errors : it was performing -1 instead of +1.
- wrong use of bit mask with bin2bcd

Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added. The Lustre developers seem to have
woken up from their sleep and have been doing a great job in cleaning up
the code and pruning unused or old cruft, the filesystem is almost
readable :)
Other than that, just a lot of basic coding style cleanups in the churn.
All have been in linux-next for a while with no reported issues.

do have a couple core changes in here as well.
Core:
- CLK_IS_CRITICAL support has been added. This should allow drivers
to properly express that a certain clk should stay on even if
their prepare/enable count drops to 0 (and in turn the parents of
these clks should stay enabled).
- A clk registration API has been added, clk_hw_register(), and
an OF clk provider API has been added, of_clk_add_hw_provider().
These APIs have been put in place to further split clk providers
from clk consumers, with the goal being to have clk providers
never deal with struct clk pointers at all. Conversion of provider
drivers is on going. clkdev has also gained support for registering
clk_hw pointers directly so we can convert drivers that don't use
devicetree.
New Drivers:
- Marvell ap806 and cp110 system controllers (with clks inside!)
- Hisilicon Hi3519 clock and reset controller
- Axis ARTPEC-6 clock controllers
- Oxford Semiconductor OXNAS clock controllers
- AXS10X I2S PLL
- Rockchip RK3399 clock and reset controller
Updates:
- MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos 542x
SoCs, and some more clk ID exporting for bus frequency scaling
- Proper BCM2835 PCM clk support and various other clks
- i.MX clk updates for i.MX6SX, i.MX7, and VF610
- Renesas updates for R-Car H3

debug_stat sysfs is read-only and represents various debugging data that
zram developers may need. This file is not meant to be used by anyone
else: its content is not documented and will change any time w/o any
notice. Therefore, the output of debug_stat file contains a version
string. To avoid any confusion, we will increase the version number
every time we modify the output.
At the moment this file exports only one value -- the number of
re-compressions, IOW, the number of times compression fast path has
failed. This stat is temporary any will be useful in case if any
per-cpu compression streams regressions will be reported.

Remove the internal part of max_comp_streams interface, since we
switched to per-cpu streams. We will keep RW max_comp_streams attr
around, because:
a) we may (silently) switch back to idle compression streams list and
don't want to disturb user space
b) max_comp_streams attr must wait for the next 'lay off cycle'; we
give user space 2 years to adjust before we remove/downgrade the attr,
and there are already several attrs scheduled for removal in 4.11, so
it's too late for max_comp_streams.
This slightly change a user visible behaviour:
- First, reading from max_comp_stream file now will always return the
number of online CPUs.
- Second, writing to max_comp_stream will not take any effect.

Pass GFP flags to zs_malloc() instead of using a fixed mask supplied to
zs_create_pool(), so we can be more flexible, but, more importantly, we
need this to switch zram to per-cpu compression streams -- zram will try
to allocate handle with preemption disabled in a fast path and switch to
a slow path (using different gfp mask) if the fast one has failed.
Apart from that, this also align zs_malloc() interface with zspool/zbud.

In case we find a socket with encapsulation enabled we should call
the encap_recv function even if just a udp header without payload is
available. The callbacks are responsible for correctly verifying and
dropping the packets.
Also, in case the header validation fails for geneve and vxlan we
shouldn't put the skb back into the socket queue, no one will pick
them up there. Instead we can simply discard them in the respective
encap_recv functions.

Current implementation updates the mtu size and notify cdc_ncm
device using USB_CDC_SET_MAX_DATAGRAM_SIZE request about datagram
size change instead of changing rx_urb_size.
Whenever mtu is being changed, datagram size should also be
updated. Also updating maxmtu formula so it takes max_datagram_size with
use of cdc_ncm_max_dgram_size() and not ctx.

We used to check dev->reg_state against NETREG_REGISTERED after each
time we are woke up. But after commit 9e641bdcfa ("net-tun:
restructure tun_do_read for better sleep/wakeup efficiency"), it uses
skb_recv_datagram() which does not check dev->reg_state. This will
result if we delete a tun/tap device after a process is blocked in the
reading. The device will wait for the reference count which was held
by that process for ever.
Fixes this by using RCV_SHUTDOWN which will be checked during
sk_recv_datagram() before trying to wake up the process during uninit.

This patch defines two new GSO definitions SKB_GSO_IPXIP4 and
SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and
NETIF_F_GSO_IPXIP6. These are used to described IP in IP
tunnel and what the outer protocol is. The inner protocol
can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and
SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT
are removed (these are both instances of SKB_GSO_IPXIP4).
SKB_GSO_IPXIP6 will be used when support for GSO with IP
encapsulation over IPv6 is added.

A domain with a frontend that does not implement a control ring has been
seen to cause a crash during domain save. This was apparently because
the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() is made
regardless of whether a control ring was connected, and hence
xenvif_hash_init() was called.
This patch brings the call to xenvif_deinit_hash() in
xenvif_disconnect_ctrl() inside the if clause that checks whether the
control ring event channel was connected. This is sufficient to ensure
it is only called if xenvif_init_hash() was called previously.
