Moving the loopback into a VRF breaks networking for the default VRF.

Support for l2 multicast flood control was added in commit b6cb5ac8331b
("net: bridge: add per-port multicast flood flag"). It allows broadcast
as it was introduced specifically for unknown multicast flood control.
But as broadcast is a special case of multicast, this may also need to
be disabled. For this purpose, introduce a flag to disable the flooding
of received l2 broadcasts. This approach is backwards compatible and
provides flexibility in filtering for the desired packet types.

When calling a dm ioctl that doesn't process any data
(IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct
dm_ioctl are left initialized. Current code is incorrectly extending
the size of data copied back to user, causing the contents of kernel
stack to be leaked to user. Fix by only copying contents before data
and allow the functions processing the ioctl to override.

The change in commit 1e2f82d1e9d1 ("statx: Kill fd-with-NULL-path
support in favour of AT_EMPTY_PATH") to error on a NULL pathname to
statx() is inconsistent.
It results in the error EINVAL for a NULL pathname. Other system calls
with similar APIs (fchownat(), fstatat(), linkat()), return EFAULT.
The solution is simply to remove the EINVAL check. As I already pointed
out in [1], user_path_at*() and filename_lookup() will handle the NULL
pathname as per the other APIs, to correctly produce the error EFAULT.

When max_size is not set or if it set to a sufficiently large
value, the nelems counter can overflow. This would cause havoc
with the automatic shrinking as it would then attempt to fit a
huge number of entries into a tiny hash table.
This patch fixes this by adding max_elems to struct rhashtable
to cap the number of elements. This is set to 2^31 as nelems is
not a precise count. This is sufficiently smaller than UINT_MAX
that it should be safe.
When max_size is set max_elems will be lowered to at most twice
max_size as is the status quo.

At least one driver, mtip32xx, has a hard coded dependency on
the value of the reserved tag used for internal commands. While
that should really be fixed up, for now let's ensure that we just
bypass the scheduler tags an allocation marked as reserved. They
are used for house keeping or error handling, so we can safely
ignore them in the scheduler.

mtip32xx supposes that 'request_idx' passed to .init_request()
is tag of the request, and use that as request's tag to initialize
command header.
After MQ IO scheduler is in, request tag assigned isn't same with
the request index anymore, so cause strange hardware failure on
mtip32xx, even whole system panic is triggered.
This patch fixes the issue by initializing command header via
request's real tag.

_tlbiel_pid() is called with a ric (Radix Invalidation Control) argument of
either RIC_FLUSH_TLB or RIC_FLUSH_ALL.
RIC_FLUSH_ALL says to invalidate the entire TLB and the Page Walk Cache (PWC).
To flush the whole TLB, we have to iterate over each set (congruence class) of
the TLB. Currently we do that and pass RIC_FLUSH_ALL each time. That is not
incorrect but it means we flush the PWC 128 times, when once would suffice.
Fix it by doing the first flush with the ric value we're passed, and then if it
was RIC_FLUSH_ALL, we downgrade it to RIC_FLUSH_TLB, because we know we have
just flushed the PWC and don't need to do it again.

Currently we implement flushing of the page walk cache (PWC) by calling
_tlbiel_pid() with a RIC (Radix Invalidation Control) value of 1 which says to
only flush the PWC.
But _tlbiel_pid() loops over each set (congruence class) of the TLB, which is
not necessary when we're just flushing the PWC.
In fact the set argument is ignored for a PWC flush, so essentially we're just
flushing the PWC 127 extra times for no benefit.
Fix it by adding tlbiel_pwc() which just does a single flush of the PWC.

If a wait_for_completion_timeout() call returns due to a timeout,
complete() can get called after returning from the wait which is
incorrect and can cause subsequent transmissions on a channel to fail.
Since the wait_for_completion_timeout() sees the completion variable
is non-zero caused by the erroneous/spurious complete() call, and
it immediately returns without waiting for the time as expected by the
client.
This patch fixes the issue by skipping complete() call for the timer
