If dma mask checks fail in atl2_probe(), it breaks off initialization,
deallocates all resources, but returns zero.
The patch adds proper error code return value and
make error code setup unified.

If the regulator probing is not yet finished this driver
might catch a -EPROBE_DEFER. Returning after this condition
did not remove the created platform device. On a repeated
call to the probe function the of_platform_device_create
fails.
Calling of_platform_device_destroy after EPROBE_DEFER resolves
this bug.

of_platform_device_destroy is the counterpart to
of_platform_device_create which is a non-static function.
After creating a platform device it might be neccessary
to destroy it to deal with -EPROBE_DEFER where a
repeated of_platform_device_create call would fail otherwise.
Therefore also make of_platform_device_destroy globally visible.

In case the DT specifies neither a regulator nor a gpio

Andrey Konovalov and idaifish@gmail.com reported crashes caused by
one skb shared_info being overwritten from __ip6_append_data()
Andrey program lead to following state :
copy -4200 datalen 2000 fraglen 2040
maxfraglen 2040 alloclen 2048 transhdrlen 0 offset 0 fraggap 6200
The skb_copy_and_csum_bits(skb_prev, maxfraglen, data + transhdrlen,
fraggap, 0); is overwriting skb->head and skb_shared_info
Since we apparently detect this rare condition too late, move the
code earlier to even avoid allocating skb and risking crashes.
Once again, many thanks to Andrey and syzkaller team.

Since v4.9 i2c-tiny-usb generates the below call trace
and longer works, since it can't communicate with the
USB device. The reason is, that since v4.9 the USB
stack checks, that the buffer it should transfer is DMA
capable. This was a requirement since v2.2 days, but it
usually worked nevertheless.

The code to fetch a 64-bit value from user space was entirely buggered,
and has been since the code was merged in early 2016 in commit
b2f680380ddf ("x86/mm/32: Add support for 64-bit __get_user() on 32-bit
kernels").
Happily the buggered routine is almost certainly entirely unused, since
the normal way to access user space memory is just with the non-inlined
"get_user()", and the inlined version didn't even historically exist.
The normal "get_user()" case is handled by external hand-written asm in
arch/x86/lib/getuser.S that doesn't have either of these issues.
There were two independent bugs in __get_user_asm_u64():
- it still did the STAC/CLAC user space access marking, even though
that is now done by the wrapper macros, see commit 11f1a4b9755f
("x86: reorganize SMAP handling in user space accesses").
This didn't result in a semantic error, it just means that the
inlined optimized version was hugely less efficient than the
allegedly slower standard version, since the CLAC/STAC overhead is
quite high on modern Intel CPU's.
- the double register %eax/%edx was marked as an output, but the %eax
part of it was touched early in the asm, and could thus clobber other
inputs to the asm that gcc didn't expect it to touch.
In particular, that meant that the generated code could look like
this:
mov (%eax),%eax
mov 0x4(%eax),%edx
where the load of %edx obviously was _supposed_ to be from the 32-bit
word that followed the source of %eax, but because %eax was
overwritten by the first instruction, the source of %edx was
basically random garbage.
The fixes are trivial: remove the extraneous STAC/CLAC entries, and mark
the 64-bit output as early-clobber to let gcc know that no inputs should
alias with the output register.

Al noticed that unsafe_put_user() had type problems, and fixed them in
commit a7cc722fff0b ("fix unsafe_put_user()"), which made me look more
at those functions.
It turns out that unsafe_get_user() had a type issue too: it limited the
largest size of the type it could handle to "unsigned long". Which is
fine with the current users, but doesn't match our existing normal
get_user() semantics, which can also handle "u64" even when that does
not fit in a long.
While at it, also clean up the type cast in unsafe_put_user(). We
actually want to just make it an assignment to the expected type of the
pointer, because we actually do want warnings from types that don't
convert silently. And it makes the code more readable by not having
that one very long and complex line.
[ This patch might become stable material if we ever end up back-porting
any new users of the unsafe uaccess code, but as things stand now this
doesn't matter for any current existing uses. ]

Export the function which checks whether an MCE is a memory error to

while at it, as mce.cpuvendor already has the CPU vendor in there.
Integrate a piece from a patch from Vishal Verma

The main reason we're exporting it is that the nfit handler
nfit_handle_mce() needs to detect a memory error properly before doing

Since commit 76b91c32dd86 ("bridge: stp: when using userspace stp stop
kernel hello and hold timers"), bridge would not start hello_timer if
stp_enabled is not KERNEL_STP when br_dev_open.
The problem is even if users set stp_enabled with KERNEL_STP later,
the timer will still not be started. It causes that KERNEL_STP can
not really work. Users have to re-ifup the bridge to avoid this.
This patch is to fix it by starting br->hello_timer when enabling
KERNEL_STP in br_stp_start.
As an improvement, it's also to start hello_timer again only when
br->stp_enabled is KERNEL_STP in br_hello_timer_expired, there is
no reason to start the timer again when it's NO_STP.

arp: always override existing neigh entries with gratuitous ARP
This patchset is spurred by discussion started at
https://patchwork.ozlabs.org/patch/760372/ where we figured that there is no
real reason for enforcing override by gratuitous ARP packets only when
arp_accept is 1. Same should happen when it's 0 (the default value).
changelog v2: handled review comments by Julian Anastasov
- fixed a mistake in a comment;
- postponed addr_type calculation to as late as possible.

Currently, when arp_accept is 1, we always override existing neigh
entries with incoming gratuitous ARP replies. Otherwise, we override
them only if new replies satisfy _locktime_ conditional (packets arrive
not earlier than _locktime_ seconds since the last update to the neigh
entry).
The idea behind locktime is to pick the very first (=> close) reply
received in a unicast burst when ARP proxies are used. This helps to
avoid ARP thrashing where Linux would switch back and forth from one
proxy to another.
This logic has nothing to do with gratuitous ARP replies that are
generally not aligned in time when multiple IP address carriers send
them into network.
This patch enforces overriding of existing neigh entries by all incoming
gratuitous ARP packets, irrespective of their time of arrival. This will
make the kernel honour all incoming gratuitous ARP packets.

The addr_type retrieval can be costly, so it's worth trying to avoid its
calculation as much as possible. This patch makes it calculated only
for gratuitous ARP packets. This is especially important since later we
may want to move is_garp calculation outside of arp_accept block, at
which point the costly operation will be executed for all setups.

This could potentially cause tcp_recvmsg() => tcp_cleanup_rbuf() =>

Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:
1) When using IPVS in direct-routing mode, normal traffic from the LVS
host to a back-end server is sometimes incorrectly NATed on the way
back into the LVS host. Patch to fix this from Julian Anastasov.
2) Calm down clang compilation warning in ctnetlink due to type
mismatch, from Matthias Kaehlcke.
3) Do not re-setup NAT for conntracks that are already confirmed, this
is fixing a problem that was introduced in the previous nf-next batch.
Patch from Liping Zhang.
4) Do not allow conntrack helper removal from userspace cthelper
infrastructure if already in used. This comes with an initial patch
to introduce nf_conntrack_helper_put() that is required by this fix.
From Liping Zhang.
5) Zero the pad when copying data to userspace, otherwise iptables fails
to remove rules. This is a follow up on the patchset that sorts out
the internal match/target structure pointer leak to userspace. Patch
from the same author, Willem de Bruijn. This also comes with a build
failure when CONFIG_COMPAT is not on, coming in the last patch of
this series.
6) SYNPROXY crashes with conntrack entries that are created via
ctnetlink, more specifically via conntrackd state sync. Patch from
Eric Leblond.
7) RCU safe iteration on set element dumping in nf_tables, from
Liping Zhang.
8) Missing sanitization of immediate date for the bitwise and cmp
expressions in nf_tables.
9) Refcounting logic for chain and objects from set elements does not
integrate into the nf_tables 2-phase commit protocol.

The boot code Makefile contains a straight 'readelf' invocation. This
causes build warnings in cross compile environments, when there is no
unprefixed readelf accessible via $PATH.
Add the missing $(CROSS_COMPILE) prefix.

Currently the following eMMC error is seen:
mmc1: mmc_select_hs200 failed, error -74
mmc1: new MMC card at address 0001
mmcblk1: mmc1:0001 V10008 7.05 GiB
mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB
mmcblk1boot1: mmc1:0001 V10008 partition 2 4.00 MiB
mmcblk1rpmb: mmc1:0001 V10008 partition 3 4.00 MiB
On imx7s-warp the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
property to properly describe that 1.8V operation is not possible.
With this change HS200 error is gone and another benefit is that the
card can operate in DDR52 mode now:
mmc1: new DDR MMC card at address 0001
mmcblk1: mmc1:0001 V10008 7.05 GiB
mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB

Pull tracing fixes from Steven Rostedt:
- Fix a bug caused by not cleaning up the new instance unique triggers
when deleting an instance. It also creates a selftest that triggers
that bug.
- Fix the delayed optimization happening after kprobes boot up self
tests being removed by freeing of init memory.
- Comment kprobes on why the delay optimization is not a problem for
removal of modules, to keep other developers from searching that
riddle.
- Fix another case of rcu not watching in stack trace tracing.
* tag 'trace-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Make sure RCU is watching before calling a stack trace
kprobes: Document how optimized kprobes are removed from module unload
selftests/ftrace: Add test to remove instance with active event triggers
selftests/ftrace: Fix bashisms
ftrace: Remove #ifdef from code and add clear_ftrace_function_probes() stub
ftrace/instances: Clear function triggers when removing instances
ftrace: Simplify glob handling in unregister_ftrace_function_probe_func()
tracing/kprobes: Enforce kprobes teardown after testing
tracing: Move postpone selftests to core from early_initcall

The PWM driver has now capability to specify the PWM polarity
which is e.g. for backlight control. Allow to make use of PWM
polarity by specifying pwm-cells to be 3 in the base dt.
