"Fix GENMASK macro shift overflow"
Nobody seems to currently use GENMASK() to fill every single last bit

In disable_outputs() we need to shut down the outgoing encoder, not the
incoming one (we have already swapped-state at this point). Without
this, we end up telling the driver to crtc->dpms(OFF) without first
encoder->dpms(OFF), and that makes some hw quite unhappy.

Commit c3ae62af8e755 ("tcp: should drop incoming frames without ACK
flag set") was created to mitigate a security vulnerability in which a
local attacker is able to inject data into locally-opened sockets by
using TCP protocol statistics in procfs to quickly find the correct
sequence number.
This broke the RFC5961 requirement to send a challenge ACK in response
to spurious RST packets, which was subsequently fixed by commit
7b514a886ba50 ("tcp: accept RST without ACK flag").
Unfortunately, the RFC5961 requirement that spurious SYN packets be
handled in a similar manner remains broken.
RFC5961 section 4 states that:
... the handling of the SYN in the synchronized state SHOULD be
performed as follows:
1) If the SYN bit is set, irrespective of the sequence number, TCP
MUST send an ACK (also referred to as challenge ACK) to the remote
peer:
<SEQ=SND.NXT><ACK=RCV.NXT><CTL=ACK>
After sending the acknowledgment, TCP MUST drop the unacceptable
segment and stop processing further.
By sending an ACK, the remote peer is challenged to confirm the loss
of the previous connection and the request to start a new connection.
A legitimate peer, after restart, would not have a TCB in the
synchronized state. Thus, when the ACK arrives, the peer should send
a RST segment back with the sequence number derived from the ACK
field that caused the RST.
This RST will confirm that the remote peer has indeed closed the
previous connection. Upon receipt of a valid RST, the local TCP
endpoint MUST terminate its connection. The local TCP endpoint
should then rely on SYN retransmission from the remote end to
re-establish the connection.
This patch lets SYN packets through the discard added in c3ae62af8e755,
so that spurious SYN packets are properly dealt with as per the RFC.
The challenge ACK is sent unconditionally and is rate-limited, so the
original vulnerability is not reintroduced by this patch.

According to the manuals I have, XScale auxiliary register should be
reached with opc_2 = 1 instead of crn = 1. cpu_xscale_proc_init
correctly uses c1, c0, 1 arguments, but cpu_xscale_do_suspend and
cpu_xscale_do_resume use c1, c1, 0. Correct suspend/resume functions to
also use c1, c0, 1.
The issue was primarily noticed thanks to qemu reporing "unsupported
instruction" on the pxa suspend path. Confirmed in PXA210/250 and PXA255
XScale Core manuals and in PXA270 and PXA320 Developers Guides.
Harware tested by me on tosa (pxa255). Robert confirmed on pxa270 board.

When disabling the interface (INTF), the change doesn't latch until next
vblank, so we need to wait for vblank.
Also, to be pedantic, in the crtc, set all the mixer stages to unused.

The Shared Memory Pool (SMP) has its own limitation, features and
state. Some examples are:
- the number of Memory Macro Block (MMB) and their size
- the number of lines that can be fetched
- the state of MMB currently allocated
- the computation of number of blocks required per plane
- client IDs ...
In order to avoid private data to be overwritten by other modules,
let's make these private to the SMP module.
Some of these depend on the hardware configuration, let's add them
to the mdp5_config struct.
In some hw configurations, some MMBs are statically tied to RGB
pipes and cannot be re-allocated dynamically. This change
introduces the concept of MMB static usage and makes sure that
dynamic MMB requests are dimensioned accordingly.
A note on passing a pipe pointer, instead of client IDs:
Client IDs are SMP-related information. Passing PIPE information
to SMP lets SMP module to find out which SMP client(s) are used.
This allows the SMP module to access the PIPE pointer, which can
be used for FIFO watermark configuration.
By the way, even though REG_MDP5_PIPE_REQPRIO_FIFO_WM_* registers
are part of the PIPE registers, their functionality is to reflect
the behavior of the SMP block. These registers access is now
restricted to the SMP module.

For mdp5, the irqs of hdmi/eDP/dsi0/dsi1 blocks get routed through the
mdp block. In order to decouple hdmi/eDP/etc, register an irq domain
in mdp5. When hdmi/dsi/etc are used with mdp4, they can directly setup
their irqs in their DT nodes as normal. When used with mdp5, instead
set the mdp device as the interrupt-parent, as in:
mdp: qcom,mdss_mdp@fd900000 {
compatible = "qcom,mdss_mdp";
interrupt-controller;
#interrupt-cells = <1>;
...
};
hdmi: qcom,hdmi_tx@fd922100 {
compatible = "qcom,hdmi-tx-8074";
interrupt-parent = <&mdp>;
interrupts = <8 0>; /* MDP5_HW_INTR_STATUS.INTR_HDMI */
...
};
There is a slight awkwardness, in that we cannot disable child irqs
at the mdp level, they can only be cleared in the child block. So
you must not use threaded irq handlers in the child. I'm not sure
if there is a better way to deal with that.

2) Don't push ethernet header before calling the netfilter output hook

This fixes an old regression introduced by commit
b0d0d915 (ipx: remove the BKL).
When a recvmsg syscall blocks waiting for new data, no data can be sent on the
same socket with sendmsg because ipx_recvmsg() sleeps with the socket locked.
This breaks mars-nwe (NetWare emulator):
- the ncpserv process reads the request using recvmsg
- ncpserv forks and spawns nwconn
- ncpserv calls a (blocking) recvmsg and waits for new requests
- nwconn deadlocks in sendmsg on the same socket
Commit b0d0d915 has simply replaced BKL locking with
lock_sock/release_sock. Unlike now, BKL got unlocked while
sleeping, so a blocking recvmsg did not block a concurrent
sendmsg.
Only keep the socket locked while actually working with the socket data and
release it prior to calling skb_recv_datagram().

When userspace doesn't provide a mask, OVS datapath generates a fully

Existing code updates cupfreq policy only while executing
cpufreq_apply_cooling() function (i.e. when notify_device != NOTIFY_INVALID).
It doesn't apply constraints when cpufreq policy update happens from any other
place but it should update the cpufreq policy with thermal constraints every
time when there is a cpufreq policy update, to keep state of
cpufreq_cooling_device and max_feq of cpufreq policy in sync. For instance
while resuming cpufreq updates cpufreq_policy and it restores default
policy->usr_policy values irrespective of cooling device's cpufreq_state since
notification gets missed because (notify_device == NOTIFY_INVALID).
Another problem, is that userspace is able to change max_freq irrespective of
cooling device's state, as notification gets missed.
This patch modifies code to maintain a global cpufreq_dev_list and applies
constraints of all matching cooling devices for policy's cpu when there is any
policy update(ends up applying the lowest max_freq among the matching cpu
cooling devices).
This patch also removes redundant check (max_freq > policy->user_policy.max),
as cpufreq framework takes care of user_policy constraints already where ever
required, otherwise its causing an issue while increasing max_freq in normal
scenerio as it restores max_freq with policy->user_policy.max which is old
(smaller) value.
