To detect a line mode console we need a message event type
for the receive mask and a command event type for the send mask.
Checking for a MSG event in the sclp send mask was wrong and
might result in line mode consoles not being detected.

TCP packets hitting the SYN proxy through the SYNPROXY target are not
validated by TCP conntrack. When th->doff is below 5, an underflow happens
when calculating the options length, causing skb_header_pointer() to
return NULL and triggering the BUG_ON().
Handle this case gracefully by checking for NULL instead of using BUG_ON().

mac80211 scan processing could get stuck if roc work for pending, but
not started when a scan request was deferred due to such roc item.
Normally the deferred scan would be started from
ieee80211_start_next_roc(), but ieee80211_sw_roc_work() calls that only
if the finished ROC was started. Fix this by calling
ieee80211_run_deferred_scan() in the case the last ROC was not actually
started.
This issue was hit relatively easily in P2P find operations where Listen
state (remain-on-channel) and Search state (scan) are repeated in a
loop.

When clients are idle for too long, hostapd sends nullfunc frames for
probing. When those are acked by the client, the idle time needs to be
updated.
To make this work (and to avoid unnecessary probing), update sta->last_rx
whenever an ACK was received for a tx packet. Only do this if the flag
IEEE80211_HW_REPORTS_TX_ACK_STATUS is set.

The problem in efi_main was that the idt was cleared before the
interrupts were disabled.
The UEFI spec states that interrupts aren't used so this shouldn't be
too much of a problem. Peripherals however don't necessarily know about
this and thus might cause interrupts to happen anyway. Even if
ExitBootServices() has been called.
This means there is a risk of an interrupt being triggered while the IDT
register is nullified and the interrupt bit hasn't been cleared,
allowing for a triple fault.
This patch disables the interrupt flag, while leaving the existing IDT
in place. The CPU won't care about the IDT at all as long as the
interrupt bit is off, so it's safe to leave it in place as nothing will
ever happen to it.

This patch fixes a problem with EFI memory maps larger than 128 entries
when booting using the EFI stub, which results in overflowing e820_map
in boot_params and an eventual halt when checking the map size in
sanitize_e820_map().
If the number of map entries is greater than what can fit in e820_map,
add the extra entries to the setup_data list using type SETUP_E820_EXT.
These extra entries are then picked up when the setup_data list is
parsed in parse_e820_ext().

Extend the APMU code with a check to only allow boot
of CPU cores that sit in the same cluster as CPU0.
This makes it possible for people to use the r8a790
CA7 boot mode with CA7-cores only. The default CA15
boot mode will enable CA15 cores only. This is an
intentional software limitation to cope with lacking
scheduler support.
By removing this patch it is possible to run all 8 cores
in parallel, but this is not recommended without out of tree
scheduler modfications or custom user space code to control
the CPU affinitiy.

This patch enables R-Car sound,
AK4643 (CN19) and AK4554 (CN20/CN21) codec chip
on Bock-W.
But, it supports PIO transfer only at this point.
User can check sound settings (Dip-switch/PFC etc)
via this patch, but will get under/over flow error
when playback/capture.
Because PIO transfer via SSI will be interrupted
"sampling rate" times per 1 second.
DMA transfer will be supported when HPB-DMAC was
enabled on r8a7778.
You will notice strange ALSA sound card HW
numbering on Bock-W board.
This came from AK4554 strange format on playback/capture.
The format on playback/capture is same on "normal" codec chip,
but AK4554 was different.
Because of that, AK4554 playback/capture are
registered as a different sound card.
