However, in imx8mq_clko2_sels[] only the first four entries are correct.

This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.
The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

Intel Wired LAN Driver Fixes 2019-02-21
This series contains fixes to ixgbe and i40e.
Majority of the fixes are to resolve XDP issues found in both drivers,
there is only one fix which is not XDP related. That one fix resolves
an issue seen on older 10GbE devices, where UDP traffic was either being
dropped or being transmitted out of order when the bit to enable L3/L4
filtering for transmit switched packets is enabled on older devices that
did not support this option.
Magnus fixes an XDP issue for both ixgbe and i40e, where receive rings
are created but no buffers are allocated for AF_XDP in zero-copy mode,
so no packets can be received and no interrupts will be generated so
that NAPI poll function that allocates buffers to the rings will never
get executed.
Björn fixes a race in XDP xmit ring cleanup for i40e, where
ndo_xdp_xmit() must be taken into consideration. Added a
synchronize_rcu() to wait for napi(s) before clearing the queue.
Jan fixes a ixgbe AF_XDP zero-copy transmit issue which can cause a
reset to be triggered, so add a check to ensure that netif carrier is
'ok' before trying to transmit packets.

causes a reset to be triggered. As it takes some time to

Commit 910cd32e55 ("parisc: Fix and enable seccomp filter support")
introduced a regression in ptrace-based syscall tampering: when tracer
changes syscall number to -1, the kernel fails to initialize %r28 with
-ENOSYS and subsequently fails to return the error code of the failed
syscall to userspace.
This erroneous behaviour could be observed with a simple strace syscall
fault injection command which is expected to print something like this:
$ strace -a0 -ewrite -einject=write:error=enospc echo hello
write(1, "hello\n", 6) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "echo: ", 6) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "write error", 11) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "\n", 1) = -1 ENOSPC (No space left on device) (INJECTED)
+++ exited with 1 +++
After commit 910cd32e55 it loops printing
something like this instead:
write(1, "hello\n", 6../strace: Failed to tamper with process 12345: unexpectedly got no error (return value 0, error 0)
) = 0 (INJECTED)
This bug was found by strace test suite.

When the driver clears the XDP xmit ring due to re-configuration or
teardown, in-progress ndo_xdp_xmit must be taken into consideration.
The ndo_xdp_xmit function is typically called from a NAPI context that
the driver does not control. Therefore, we must be careful not to
clear the XDP ring, while the call is on-going. This patch adds a
synchronize_rcu() to wait for napi(s) (preempt-disable regions and
softirqs), prior clearing the queue. Further, the __I40E_CONFIG_BUSY
flag is checked in the ndo_xdp_xmit implementation to avoid touching
the XDP xmit queue during re-configuration.

The default value of ARCH_SLAB_MINALIGN in "include/linux/slab.h" is
"__alignof__(unsigned long long)" which for ARC unexpectedly turns out
to be 4. This is not a compiler bug, but as defined by ARC ABI [1]
Thus slab allocator would allocate a struct which is 32-bit aligned,
which is generally OK even if struct has long long members.
There was however potetial problem when it had any atomic64_t which
use LLOCKD/SCONDD instructions which are required by ISA to take
64-bit addresses. This is the problem we ran into

The fix is to make sure slab allocations are 64-bit aligned.
Do note that atomic64_t is __attribute__((aligned(8)) which means gcc
does generate 64-bit aligned references, relative to beginning of
container struct. However the issue is if the container itself is not
64-bit aligned, atomic64_t ends up unaligned which is what this patch
ensures.
