This adds a helper to check whether a device needs to
use bounce buffer. It also provides a boot time option
to disable the bounce buffer. Users can use this to
prevent the iommu driver from using the bounce buffer
for performance gain.

This patch adds decriptions for mt8183 IOMMU and SMI.
mt8183 has only one M4U like mt8173 and is also MTK IOMMU gen2 which
uses ARM Short-Descriptor translation table format.
The mt8183 M4U-SMI HW diagram is as below:
EMI

larb0 larb1 IPU0 IPU1 larb4 larb5 larb6 CCU
disp vdec img cam venc img cam
All the connections are HW fixed, SW can NOT adjust it.
Compared with mt8173, we add a GALS(Global Async Local Sync) module
between SMI-common and M4U, and additional GALS between larb2/3/5/6
and SMI-common. GALS can help synchronize for the modules in different
clock frequency, it can be seen as a "asynchronous fifo".
GALS can only help transfer the command/data while it doesn't have
the configuring register, thus it has the special "smi" clock and it
doesn't have the "apb" clock. From the diagram above, we add "gals0"
and "gals1" clocks for smi-common and add a "gals" clock for smi-larb.
>From the diagram above, IPU0/IPU1(Image Processor Unit) and CCU(Camera
Control Unit) is connected with smi-common directly, we can take them
as "larb2", "larb3" and "larb7", and their register spaces are
different with the normal larb.

To address the requirements of embargoed hardware issues, like Meltdown,
Spectre, L1TF etc. it is necessary to define and document a process for
handling embargoed hardware security issues.
Following the discussion at the maintainer summit 2018 in Edinburgh
(https://lwn.net/Articles/769417/) the volunteered people have worked
out a process and a Memorandum of Understanding. The latter addresses
the fact that the Linux kernel community cannot sign NDAs for various
reasons.
The initial contact point for hardware security issues is different from
the regular kernel security contact to provide a known and neutral
interface for hardware vendors and researchers. The initial primary
contact team is proposed to be staffed by Linux Foundation Fellows, who
are not associated to a vendor or a distribution and are well connected
in the industry as a whole.
The process is designed with the experience of the past incidents in
mind and tries to address the remaining gaps, so future (hopefully rare)
incidents can be handled more efficiently. It won't remove the fact,
that most of this has to be done behind closed doors, but it is set up
to avoid big bureaucratic hurdles for individual developers.
The process is solely for handling hardware security issues and cannot
be used for regular kernel (software only) security bugs.
This memo can help with hardware companies who, and I quote, "[my
manager] doesn't want to bet his job on the list keeping things secret."
This despite numerous leaks directly from that company over the years,
and none ever so far from the kernel security team. Cognitive
dissidence seems to be a requirement to be a good manager.
To accelerate the adoption of this process, we introduce the concept of
ambassadors in participating companies. The ambassadors are there to
guide people to comply with the process, but are not automatically
involved in the disclosure of a particular incident.

Pull x86 fixes from Thomas Gleixner:
"A few fixes for x86:
- Fix a boot regression caused by the recent bootparam sanitizing
change, which escaped the attention of all people who reviewed that
code.
- Address a boot problem on machines with broken E820 tables caused
by an underflow which ended up placing the trampoline start at
physical address 0.
- Handle machines which do not advertise a legacy timer of any form,
but need calibration of the local APIC timer gracefully by making
the calibration routine independent from the tick interrupt. Marked
for stable as well as there seems to be quite some new laptops
rolled out which expose this.
- Clear the RDRAND CPUID bit on AMD family 15h and 16h CPUs which are
affected by broken firmware which does not initialize RDRAND
correctly after resume. Add a command line parameter to override
this for machine which either do not use suspend/resume or have a
fixed BIOS. Unfortunately there is no way to detect this on boot,
so the only safe decision is to turn it off by default.
- Prevent RFLAGS from being clobbers in CALL_NOSPEC on 32bit which
caused fast KVM instruction emulation to break.
- Explain the Intel CPU model naming convention so that the repeating
discussions come to an end"

There have been reports of RDRAND issues after resuming from suspend on
some AMD family 15h and family 16h systems. This issue stems from a BIOS
not performing the proper steps during resume to ensure RDRAND continues
to function properly.
RDRAND support is indicated by CPUID Fn00000001_ECX[30]. This bit can be
reset by clearing MSR C001_1004[62]. Any software that checks for RDRAND
support using CPUID, including the kernel, will believe that RDRAND is
not supported.
Update the CPU initialization to clear the RDRAND CPUID bit for any family
15h and 16h processor that supports RDRAND. If it is known that the family
15h or family 16h system does not have an RDRAND resume issue or that the
system will not be placed in suspend, the "rdrand=force" kernel parameter
can be used to stop the clearing of the RDRAND CPUID bit.
Additionally, update the suspend and resume path to save and restore the
MSR C001_1004 value to ensure that the RDRAND CPUID setting remains in
place after resuming from suspend.
Note, that clearing the RDRAND CPUID bit does not prevent a processor
that normally supports the RDRAND instruction from executing it. So any
code that determined the support based on family and model won't #UD.

sk_validate_xmit_skb() and drivers depend on the sk member of
struct sk_buff to identify segments requiring encryption.
Any operation which removes or does not preserve the original TLS
socket such as skb_orphan() or skb_clone() will cause clear text
leaks.
Make the TCP socket underlying an offloaded TLS connection
mark all skbs as decrypted, if TLS TX is in offload mode.
Then in sk_validate_xmit_skb() catch skbs which have no socket
(or a socket with no validation) and decrypted flag set.
Note that CONFIG_SOCK_VALIDATE_XMIT, CONFIG_TLS_DEVICE and
sk->sk_validate_xmit_skb are slightly interchangeable right now,
they all imply TLS offload. The new checks are guarded by
CONFIG_TLS_DEVICE because that's the option guarding the
sk_buff->decrypted member.
Second, smaller issue with orphaning is that it breaks
the guarantee that packets will be delivered to device
queues in-order. All TLS offload drivers depend on that
scheduling property. This means skb_orphan_partial()'s
trick of preserving partial socket references will cause
issues in the drivers. We need a full orphan, and as a
result netem delay/throttling will cause all TLS offload
skbs to be dropped.
Reusing the sk_buff->decrypted flag also protects from
leaking clear text when incoming, decrypted skb is redirected
(e.g. by TC).
See commit 0608c69c9a80 ("bpf: sk_msg, sock{map|hash} redirect
through ULP") for justification why the internal flag is safe.
The only location which could leak the flag in is tcp_bpf_sendmsg(),
which is taken care of by clearing the previously unused bit.
v2:
- remove superfluous decrypted mark copy (Willem);
- remove the stale doc entry (Boris);
- rely entirely on EOR marking to prevent coalescing (Boris);
- use an internal sendpages flag instead of marking the socket
(Boris).
v3 (Willem):
- reorganize the can_skb_orphan_partial() condition;
- fix the flag leak-in through tcp_bpf_sendmsg.

Pull pti updates from Thomas Gleixner:
"The performance deterioration departement is not proud at all to
present yet another set of speculation fences to mitigate the next
chapter in the 'what could possibly go wrong' story.
The new vulnerability belongs to the Spectre class and affects GS
based data accesses and has therefore been dubbed 'Grand Schemozzle'
for secret communication purposes. It's officially listed as
CVE-2019-1125.
Conditional branches in the entry paths which contain a SWAPGS
instruction (interrupts and exceptions) can be mis-speculated which
results in speculative accesses with a wrong GS base.
This can happen on entry from user mode through a mis-speculated
branch which takes the entry from kernel mode path and therefore does
not execute the SWAPGS instruction. The following speculative accesses
are done with user GS base.
On entry from kernel mode the mis-speculated branch executes the
SWAPGS instruction in the entry from user mode path which has the same
effect that the following GS based accesses are done with user GS
base.
If there is a disclosure gadget available in these code paths the
mis-speculated data access can be leaked through the usual side
channels.
The entry from user mode issue affects all CPUs which have speculative
execution. The entry from kernel mode issue affects only Intel CPUs
which can speculate through SWAPGS. On CPUs from other vendors SWAPGS
has semantics which prevent that.
SMAP migitates both problems but only when the CPU is not affected by
the Meltdown vulnerability.
The mitigation is to issue LFENCE instructions in the entry from
kernel mode path for all affected CPUs and on the affected Intel CPUs
also in the entry from user mode path unless PTI is enabled because
the CR3 write is serializing.
The fences are as usual enabled conditionally and can be completely
disabled on the kernel command line. The Spectre V1 documentation is
updated accordingly.
A big "Thank You!" goes to Josh for doing the heavy lifting for this
round of hardware misfeature 'repair'. Of course also "Thank You!" to
everybody else who contributed in one way or the other"

minor cleanup of documentation, updating to more current status.

Looks like we were slightly overzealous with the shutdown()
cleanup. Even though the sock->sk_state can reach CLOSED again,
socket->state will not got back to SS_UNCONNECTED once
connections is ESTABLISHED. Meaning we will see EISCONN if
we try to reconnect, and EINVAL if we try to listen.
Only listen sockets can be shutdown() and reused, but since
ESTABLISHED sockets can never be re-connected() or used for
listen() we don't need to try to clean up the ULP state early.

Commit 837158b847a4 ("dt-bindings: Check the examples against the
