If the mdp_* nodes are under an mdp sub-node, their corresponding
platform device does not automatically get its iommu assigned properly.
Fix this by moving the mdp component nodes up a level such that they are
siblings of mdp and all other SoC subsystems. This also simplifies the
device tree.
Although it fixes iommu assignment issue, it also break compatibility
with old device tree. So, the patch in driver is needed to iterate over
sibling mdp device nodes, not child ones, to keep driver work properly.

The rk3399 has multiple variants with different frequency ratings.
The operating points currently in the kernel stem from the op1 variant
used in Gru ChromeOS devices and may not be suitable for general rk3399
chips. Therefore bring it back to the official general operating points.

The OP1 is a rk3399 variant used in ChromeOS devices with a slightly
higher frequency rating compared to the regular rk3399, but right now
the only available operating points don't match either variant
with both needing adjustments to actually fit their specs.
Therefore introduce separate operting points, from the ChromeOS kernel,
for the OP1 and use it on Gru devices.

ftrace use module_alloc() to allocate trampoline pages. The mapping of
module_alloc() is RWX, which makes sense as the memory is written to right
after allocation. But nothing makes these pages RO after writing to them.
Add proper set_memory_rw/ro() calls to protect the trampolines after
modification.

Interrupts should not be enabled at this early in the boot process. It is
also fine to leave interrupts enabled during this time as there's only one
CPU running, and on_each_cpu() means to only run on the current CPU.
If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with
interrupts disabled. Don't trigger a BUG_ON() in that case.

Add a testcase to test kprobes via ftrace interface
with many concurrent kprobe events.
This tries to add many kprobe events (up to 256) on
kernel functions. To avoid making ftrace-based
kprobes (kprobes on fentry), it skips first N bytes
(on x86 N=5, on ppc or arm N=4) of function entry.
After that, it enables all those events, disable it,
and remove it.
Since the unoptimization buffer reclaiming will
be delayed, after removing events, it will wait
enough time.

Fix kprobes to set(recover) RWX bits correctly on trampoline
buffer before releasing it. Releasing readonly page to
module_memfree() crash the kernel.
Without this fix, if kprobes user register a bunch of kprobes
in function body (since kprobes on function entry usually
use ftrace) and unregister it, kernel hits a BUG and crash.

Andrey Konovalov reported crashes in ipv4_mtu()
I could reproduce the issue with KASAN kernels, between
10.246.7.151 and 10.246.7.152 :
1) 20 concurrent netperf -t TCP_RR -H 10.246.7.152 -l 1000 &
2) At the same time run following loop :
while :
do
ip ro add 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
ip ro del 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
done
Cong Wang attempted to add back rt->fi in commit
82486aa6f1b9 ("ipv4: restore rt->fi for reference counting")
but this proved to add some issues that were complex to solve.
Instead, I suggested to add a refcount to the metrics themselves,
being a standalone object (in particular, no reference to other objects)
I tried to make this patch as small as possible to ease its backport,
instead of being super clean. Note that we believe that only ipv4 dst
need to take care of the metric refcount. But if this is wrong,
this patch adds the basic infrastructure to extend this to other
families.
Many thanks to Julian Anastasov for reviewing this patch, and Cong Wang
for his efforts on this problem.

This fix addresses two problems in the way the DSCP field is formulated
on the encapsulating header of IPv6 tunnels.
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661
1) The IPv6 tunneling code was manipulating the DSCP field of the
encapsulating packet using the 32b flowlabel. Since the flowlabel is
only the lower 20b it was incorrect to assume that the upper 12b
containing the DSCP and ECN fields would remain intact when formulating
the encapsulating header. This fix handles the 'inherit' and
'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable.
2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was
incorrect and resulted in the DSCP value always being set to 0.
Commit 90427ef5d2a4 ("ipv6: fix flow labels when the traffic class
is non-0") caused the regression by masking out the flowlabel
which exposed the incorrect handling of the DSCP portion of the
flowlabel in ip6_tunnel and ip6_gre.

sometimes ICMP replies to INIT chunks are ignored by the client, even if
the encapsulated SCTP headers match an open socket. This happens when the
ICMP packet is carried by a paged skb: use skb_header_pointer() to read
packet contents beyond the SCTP header, so that chunk header and initiate
tag are validated correctly.
v2:
- don't use skb_header_pointer() to read the transport header, since
icmp_socket_deliver() already puts these 8 bytes in the linear area.
- change commit message to make specific reference to INIT chunks.

There is a race condition in llc_ui_bind if two or more processes/threads
try to bind a same socket.
If more processes/threads bind a same socket success that will lead to
two problems, one is this action is not what we expected, another is
will lead to kernel in unstable status or oops(in my simple test case,
cause llc2.ko can't unload).
The current code is test SOCK_ZAPPED bit to avoid a process to
bind a same socket twice but that is can't avoid more processes/threads
try to bind a same socket at the same time.
So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect.
