Booting with GICR_CTLR.EnableLPI=1 is usually a bad idea, and may
result in subtle memory corruption. Detecting this is thus pretty
important.
On detecting that LPIs are still enabled, we taint the kernel (because
we're not sure of anything anymore), and try to disable LPIs. This can
fail, as implementations are allowed to implement GICR_CTLR.EnableLPI
as a one-way enable, meaning the redistributors cannot be reprogrammed
with new tables.
Should this happen, we fail probing the redistributor and warn the user
that things are pretty dire.

My Nuvoton 6xx in a Dell XPS-13 has been intermittently failing to work
(necessitating a reboot). The problem seems to be that the TPM gets into a
state where the partial self-test doesn't return TPM_RC_SUCCESS (meaning
all tests have run to completion), but instead returns TPM_RC_TESTING
(meaning some tests are still running in the background). There are
various theories that resending the self-test command actually causes the
tests to restart and thus triggers more TPM_RC_TESTING returns until the
timeout is exceeded.
There are several issues here: firstly being we shouldn't slow down the
boot sequence waiting for the self test to complete once the TPM
backgrounds them. It will actually make available all functions that have
passed and if it gets a failure return TPM_RC_FAILURE to every subsequent
command. So the fix is to kick off self tests once and if they return
TPM_RC_TESTING log that as a backgrounded self test and continue on. In
order to prevent other tpm users from seeing any TPM_RC_TESTING returns
(which it might if they send a command that needs a TPM subsystem which is
still under test), we loop in tpm_transmit_cmd until either a timeout or we
don't get a TPM_RC_TESTING return.
Finally, there have been observations of strange returns from a partial
test. One Nuvoton is occasionally returning TPM_RC_COMMAND_CODE, so treat
any unexpected return from a partial self test as an indication we need to
run a full self test.
[jarkko.sakkinen@linux.intel.com: cleaned up some klog messages and
dropped tpm_transmit_check() helper function from James' original
commit.]

TPM2 can return TPM2_RC_RETRY to any command and when it does we get
unexpected failures inside the kernel that surprise users (this is
mostly observed in the trusted key handling code). The UEFI 2.6 spec
has advice on how to handle this:
The firmware SHALL not return TPM2_RC_RETRY prior to the completion
of the call to ExitBootServices().
Implementer’s Note: the implementation of this function should check
the return value in the TPM response and, if it is TPM2_RC_RETRY,
resend the command. The implementation may abort if a sufficient
number of retries has been done.
So we follow that advice in our tpm_transmit() code using
TPM2_DURATION_SHORT as the initial wait duration and
TPM2_DURATION_LONG as the maximum wait time. This should fix all the
in-kernel use cases and also means that user space TSS implementations
don't have to have their own retry handling.

The Acer Acer Veriton X4110G has a TPM device detected as:
tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71)
After the first S3 suspend, the following error appears during resume:
tpm tpm0: A TPM error(38) occurred continue selftest
Any following S3 suspend attempts will now fail with this error:
tpm tpm0: Error (38) sending savestate before suspend
PM: Device 00:0b failed to suspend: error 38
Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is
not in the correct state. This indicates that the platform BIOS
is not sending the usual TPM_Startup command during S3 resume.
>From this point onwards, all TPM commands will fail.
The same issue was previously reported on Foxconn 6150BK8MC and
Sony Vaio TX3.
The platform behaviour seems broken here, but we should not break
suspend/resume because of this.
When the unexpected TPM state is encountered, set a flag to skip the
affected TPM_SaveState command on later suspends.

TPM2_CC_Create(0x153) and TPM2_CC_CreatePrimary (0x131) involve generation
of crypto keys which can be a computationally intensive task. The timeout
is set to 3min. Rather than increasing default timeout a new constant is
added, to not stall for too long on regular commands failures.

The correct sequence is to first request locality and only after
that perform cmd_ready handshake, otherwise the hardware will drop
the subsequent message as from the device point of view the cmd_ready
handshake wasn't performed. Symmetrically locality has to be relinquished
only after going idle handshake has completed, this requires that
go_idle has to poll for the completion and as well locality
relinquish has to poll for completion so it is not overridden
in back to back commands flow.
Two wrapper functions are added (request_locality relinquish_locality)
to simplify the error handling.
The issue is only visible on devices that support multiple localities.

Since hclk_sd and pclk_ddr source clock from CPLL or GPLL,
and these two PLL may change their frequency. If we do not
assign right id to pclk_ddr and hclk_sd, they will alway use
default cur register value, and may get the frequency
exceed their signed off frequency. So assign correct Id
for them, then we can assign frequency for them in dts.

The newly added clock notifier may return an error code but so far the
error output in the function would only return an error pointer from
registering the clock.
So when the clock notifier fails the clock would be unregistered but the
return would still be the clock pointer which could then not be
dereferenced correctly. So fix the error handling to prevent that.

Some UDC may want to allocate endpoints dynamically, either because
the HW supports an arbitrary large number or because (like the Aspeed
BMC SoCs), the pool of HW endpoints is shared between multiple gadgets.
The allocation side can be done rather easily using the existing
match_ep() UDC hook.
However we have no good place to "free" them.
This implements a "simple" variant of this, which calls an EP dispose
callback on all EPs associated with a gadget when the composite device
gets unbound.
This is required by my upcoming Aspeed vHub driver.

that the parent of SDMMC phase clock should be sclk_sdmmc0, but not
sclk_sdmmc. However, the naming of the sdmmc clocks varies in the
manual with the card clock having the 0 while the hclk is named
without appended 0. So standardize one one format to prevent
confusion, as there also is only one (non-sdio) mmc controller on
the soc.

The Allwinner pinctrl device tree binding suggests that a clock named
"apb" would drive the pin controller IP. However (for legacy reasons) we
rely on this clock actually being the first clock defined.

clock called "apb" if there is more than one clock referenced.

Pull libnvdimm fixes from Dan Williams:
"Two regression fixes, two bug fixes for older issues, two fixes for
new functionality added this cycle that have userspace ABI concerns,
and a small cleanup. These have appeared in a linux-next release and
have a build success report from the 0day robot.
* The 4.16 rework of altmap handling led to some configurations
leaking page table allocations due to freeing from the altmap
reservation rather than the page allocator.
The impact without the fix is leaked memory and a WARN() message
when tearing down libnvdimm namespaces. The rework also missed a
place where error handling code needed to be removed that can lead
to a crash if devm_memremap_pages() fails.
* acpi_map_pxm_to_node() had a latent bug whereby it could
misidentify the closest online node to a given proximity domain.
* Block integrity handling was reworked several kernels back to allow
calling add_disk() after setting up the integrity profile.
The nd_btt and nd_blk drivers are just now catching up to fix
automatic partition detection at driver load time.
* The new peristence_domain attribute, a platform indicator of
whether cpu caches are powerfail protected for example, is meant to
be a single value enum and not a set of flags.
This oversight was caught while reviewing new userspace code in
libndctl to communicate the attribute.
Fix this new enabling up so that we are not stuck with an unwanted
userspace ABI"

Fixes missing characters on kernel console at low baud rates (i.e.9600).
The driver should poll TX_RDY or TX_FIFO_EMP instead of TX_EMP to ensure
that the transmitter holding register (THR) is ready to receive a new byte.
TX_EMP tells us when it is possible to send a break sequence via
SND_BRK_SEQ. While this also indicates that both the THR and the TSR are
empty, it does not guarantee that a new byte can be written just yet.

Main change is a patch to reject getfb call for multiplanar framebuffers,
then we have a couple of error path fixes on the sun4i driver. Still on that
driver there is a clk fix and finally a mmap offset fix on the udl driver.

drm/imx: fixes for early vblank event issue, array underflow error
- fix an array underflow error by reordering the range check before the array
subscript in ipu-prg.
- make some local functions static in ipuv3-plane.
- add a missng header for ipu_planes_assign_pre in ipuv3-plane.
- move arming of the vblank event from atomic_begin to atomic_flush, to avoid
signalling atomic commit completion to userspace before plane atomic_update
has finished, due to a race condition that is likely to be hit on i.MX6QP on
PRE enabled channels.

PF needs to assert the VF reset when it receives the request to
reset from VF. After receiving request PF ackknowledges the
request by replying back MBX_ASSERTING_RESET message to VF.
VF then goes to pending state and wait for hardware to complete
the reset.
This patch contains code to handle the received VF message, inform
the VF of assertion and reset the VF using cmdq interface.

Reset Asserting message is forwarded by PF to inform VF about
the hardware reset which is about to happen. This might be due
to the earlier VF reset request received by the PF or because PF
for any reason decides to undergo reset. This message results in
VF to go in pending state in which it polls the hardware to
complete the reset and then further resets/tears its own stack.

Current mailbox CRQ could consists of both synchronous and async
responses from the PF. Synchronous responses are time critical
and should be handed over to the waiting tasks/context as quickly
as possible otherwise timeout occurs.
Above problem gets accentuated if CRQ consists of even single
async message. Hence, it is important to have quick handling of
synchronous messages and maybe deferred handling of async messages
This patch introduces separate ARQ(async receive queues) for the
async messages. These messages are processed later with repsect
to mailbox task while synchronous messages still gets processed
in context to mailbox interrupt.
ARQ is important as VF reset introduces some new async messages
like MBX_ASSERTING_RESET which adds up to the presssure on the
responses for synchronousmessages and they timeout even more
quickly.

After the hardware reset we should re-fetch the configuration from
PF like queue info and tc info. This might have impact on allocations
made like that of TQPs. Hence, we should release all such allocations
and re-allocate fresh according to new fetched configuration after
reset.
