With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...
The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

Despite RISC-V having a direct 'fence.i' instruction available to
userspace (which we can't trap!), that's not actually viable when
running on Linux because the kernel might schedule a process on another
hart. There is no way for userspace to handle this without invoking the
kernel (as it doesn't know the thread->hart mappings), so we've defined
a RISC-V specific system call to flush the instruction cache.
This patch adds both a system call and a VDSO entry. If possible, we'd
like to avoid having the system call be considered part of the
user-facing ABI and instead restrict that to the VDSO entry -- both just
in general to avoid having additional user-visible ABI to maintain, and
because we'd prefer that users just call the VDSO entry because there
might be a better way to do this in the future (ie, one that doesn't
require entering the kernel).

The RISC-V ISA allows for instruction caches that are not coherent WRT
stores, even on a single hart. As a result, we need to explicitly flush
the instruction cache whenever marking a dirty page as executable in
order to preserve the correct system behavior.
Local instruction caches aren't that scary (our implementations actually
flush the cache, but RISC-V is defined to allow higher-performance
implementations to exist), but RISC-V defines no way to perform an
instruction cache shootdown. When explicitly asked to do so we can
shoot down remote instruction caches via an IPI, but this is a bit on
the slow side.
Instead of requiring an IPI to all harts whenever marking a page as
executable, we simply flush the currently running harts. In order to
maintain correct behavior, we additionally mark every other hart as
needing a deferred instruction cache which will be taken before anything
runs on it.

that too.

Once the inode item writeback errors is already fixed, it's time to fix the same

Although there were no reports of users hitting this bug in dquot code (at least
none I've seen), the bug is there and I was already planning to fix it when the
correct approach to fix the inodes part was decided.
This patch aims to fix the same problem in dquot code, regarding failed buffers
being unable to be resubmitted once they are flush locked.

usb: fixes for v4.15-rc2
After a long time, we finally have a good solution for how to handle
OS descriptor on FFS. From now on we will force the Reserved field to
be 1 as mandated by the specification.
Apart from that, we have a couple other smaller fixes:
- FFS learned to not sleep in atomic context.
- UDC-core has a fix for the way we set a UDC's operating speed.
- Renesas USB3 has a fix for the maximum number of pipes supported
- Allow legacy drivers to be compiled without USB_ETH
- Fix some coccinelle warnings
Here are some new device ids.
All have been in linux-next with no reported issues.

All of the H5 boards in the kernel reference the MMC0 CD pin twice in
their DT, so strict mode will make the MMC driver fail to load.
To keep existing DTs working, disable strict mode in the H5 driver.

To use pin PF4 as the RX signal of UART0, we have to write 0b011 into

On the A80 the pins on port B can trigger interrupts, and those are
assigned to the second interrupt bank.
Having two pins assigned to the same interrupt bank/pin combination does
not look healthy (instead more like a copy&paste bug from pins PA14-PA16),
so fix the interrupt bank for pins PB14-PB16, which is actually 1.
I don't have any A80 board, so could not test this.

tcp_v6_send_reset() expects to receive an skb with skb->cb[] layout as
used in TCP stack.
MD5 lookup uses tcp_v6_iif() and tcp_v6_sdif() and thus
TCP_SKB_CB(skb)->header.h6
This patch probably fixes RST packets sent on behalf of a timewait md5
ipv6 socket.
Before Florian patch, tcp_v6_restore_cb() was needed before jumping to
no_tcp_socket label.

Similar to commit d7fb60b9cafb ("net_sched: get rid of tcfa_rcu"),
TC actions don't need to respect RCU grace period, because it
is either just detached from tc filter (standalone case) or
it is removed together with tc filter (bound case) in which case
RCU grace period is already respected at filter layer.

drm_atomic_helper_wait_for_vblanks will go away in the future.
The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits
have completed flipping before the commit_tail returns. This must be ensured
by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do
a less agressive wait, which is fine for imx-drm.
