Zero bits on the mask signify a "don't care" on the corresponding bits
in key. Some HWs require those bits on the key to be zero. Since these
bits are masked anyway, it's okay to provide the masked key to all
drivers.

Before, encx24j600_rx_packets did not update encx24j600_priv's next_packet
member when an error occurred during packet handling (either because the
packet's RSV header indicates an error or because the encx24j600_receive_packet
method can't allocate an sk_buff).
If the next_packet member is not updated, the ERXTAIL register will be set to
the same value it had before, which means the bad packet remains in the
component's memory and its RSV header will be read again when a new packet
arrives. If the RSV header indicates a bad packet or if sk_buff allocation
continues to fail, new packets will be stored in the component's memory until
that memory is full, after which packets will be dropped.
The SETPKTDEC command is always executed though, so the encx24j600 hardware has
an incorrect count of the packets in its memory.
To prevent this, the next_packet member should always be updated, allowing the
packet to be skipped (either because it's bad, as indicated in its RSV header,
or because allocating an sk_buff failed). In the allocation failure case, this
does mean dropping a valid packet, but dropping the oldest packet to keep as
much memory as possible available for new packets seems preferable to keeping
old (but valid) packets around while dropping new ones.

The timer handling in this driver is broken in several ways:
- corkscrew_open() initializes and arms a timer before requesting the
device interrupt. If the request fails the timer stays armed.
A second call to corkscrew_open will unconditionally reinitialize the
quued timer and arm it again. Also a immediate device removal will leave
the timer queued because close() is not called (open() failed) and
therefore nothing issues del_timer().
The reinitialization corrupts the link chain in the timer wheel hash
bucket and causes a NULL pointer dereference when the timer wheel tries
to operate on that hash bucket. Immediate device removal lets the link
chain poke into freed and possibly reused memory.
Solution: Arm the timer after the successful irq request.
- corkscrew_close() uses del_timer()
On close the timer is disarmed with del_timer() which lets the following
code race against a concurrent timer expiry function.
Solution: Use del_timer_sync() instead
- corkscrew_close() calls del_timer() unconditionally
del_timer() is invoked even if the timer was never initialized. This
works by chance because the struct containing the timer is zeroed at
allocation time.
Solution: Move the setup of the timer into corkscrew_setup().

The of_platform_populate call in the openrisc arch code is now redundant
as the DT core provides a default call. Openrisc has a NULL match table
which means only top level nodes with compatible strings will have

match table such as "simple-bus" which should be fine as openrisc

Fix signal handling for when signals are handled as the result of timers
or exceptions, previous code assumed syscalls. This was noticeable with X
crashing where it uses SIGALRM.
This patch restores all regs before returning to userspace via
_resume_userspace instead of via syscall return path.
The rt_sigreturn syscall is more like a context switch than a function
call; it entails a return from one context (the signal handler) to another
(the process in question). For a context switch like this there are
effectively no call-saved regs that remain constant across the transition.

We shouldn't dereference "iommu" until after we have checked that it is
non-NULL.

Pull MIPS fixes from Ralf Baechle:
"Two more MIPS fixes for 4.9:
- RTC: Return -ENODEV so an external RTC will be tried
- Fix mask of GPE frequency
These two have been tested on Imagination's automated test system and
also both received positive reviews on the linux-mips mailing list"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: Lantiq: Fix mask of GPE frequency
MIPS: Return -ENODEV from weak implementation of rtc_mips_set_time
Dump and reset doesn't work unless cmpxchg64() is used both from packet
and control plane paths. This approach is going to be slow though.
Instead, use a percpu seqcount to fetch counters consistently, then
subtract bytes and packets in case a reset was requested.
The cpu that running over the reset code is guaranteed to own this stats
exclusively, we have to turn counters into signed 64bit though so stats
update on reset don't get wrong on underflow.
This patch is based on original sketch from Eric Dumazet.

The hardware documentation says bit 11:10 are used for the GPE
frequency selection. Fix the mask in the define to match these bits.

The sync_cmos_clock function in kernel/time/ntp.c first tries to update
the internal clock of the cpu by calling the "update_persistent_clock64"
architecture specific function. If this returns -ENODEV, it then tries
to update an external RTC using "rtc_set_ntp_time".
On the mips architecture, the weak implementation of the underlying
function would return 0 if it wasn't overridden. This meant that the
sync_cmos_clock function would never try to update an external RTC
(if both CONFIG_GENERIC_CMOS_UPDATE and CONFIG_RTC_SYSTOHC are
configured)
Returning -ENODEV instead, means that an external RTC will be tried.

In commit 02cea39586 ("genirq: Provide disable_hardirq()")
Peter introduced disable_hardirq() for netpoll, but it is forgotten
to use it for e1000.
This patch changes disable_irq() to disable_hardirq() for e1000.
