This was inspired by mchehab@redhat.com's observation that we
didn't have EDAC configured on by default in both files. In addition,
we were setting INITRAMFS_SOURCE to a non-empty string, which isn't
a very common default and required editing to do test builds.

Is possible that we stop queue and then do not wake up it again,
especially when packets are transmitted fast. That can be easily
reproduced with modified tx queue entry_num to some small value e.g. 16.
If mac80211 already hold local->queue_stop_reason_lock, then we can wait
on that lock in both rt2x00queue_pause_queue() and
rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock
is possible that __ieee80211_wake_queue() will be performed before
__ieee80211_stop_queue(), hence we stop queue and newer wake up it
again.
Another race condition is possible when between rt2x00queue_threshold()
check and rt2x00queue_pause_queue() we will process all pending tx
buffers on different cpu. This might happen if for example interrupt
will be triggered on cpu performing rt2x00mac_tx().
To prevent race conditions serialize pause/unpause by queue->tx_lock.

On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10
Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.

num_sifr could go negative since acpi_pcc_get_sqty() returns -EINVAL
on error. Then it could bypass the sanity check (num_sifr > 255).
The subsequent call to kzalloc() would allocate a small buffer, leading

and register rfkill for wifi which can not be unblocked.
Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.
Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no

commit ea4fc0d619 (ipv4: Don't use rt->rt_{src,dst} in ip_queue_xmit())
added a serious regression on synflood handling.
Simon Kirby discovered a successful connection was delayed by 20 seconds
before being responsive.
In my tests, I discovered that xmit frames were lost, and needed ~4
retransmits and a socket dst rebuild before being really sent.
In case of syncookie initiated connection, we use a different path to
initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared.
As ip_queue_xmit() now depends on inet flow being setup, fix this by
copying the temp flowi4 we use in cookie_v4_check().

Amba core assumes the pclk to be named as apb_pclk. During device probe,
it tries to get that clock and enable that. When PM_RUNTIME is enabled,
dma clock is not explicitly enabled in pl330_probe, which causes device
probe to fail. Adding a clkdev entry for apb_pclk for mdma1 fixes the
problem.
This patch fixes following runtime error.
