Pull TPM updates from James Morris:
"Here are the TPM updates from Jarkko for v4.14, which I've placed in
their own branch (next-tpm). I ended up cherry-picking them as other
changes had been made in Jarkko's branch after he sent me his original
pull request.
I plan on maintaining a separate branch for TPM (and other security
subsystems) from now on.
From Jarkko: 'Not much this time except a few fixes'"
* 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
tpm: ibmvtpm: simplify crq initialization and document crq format
tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic drivers
Documentation: tpm: add powered-while-suspended binding documentation
tpm: tpm_crb: constify acpi_device_id.
tpm: vtpm: constify vio_device_id

The crq is passed in registers and is the same on BE and LE hosts.
However, current implementation allocates a structure on-stack to
represent the crq, initializes the members swapping them to BE, and
loads the structure swapping it from BE. This is pointless and causes
GCC warnings about ununitialized members. Get rid of the structure and
the warnings.

The patch simply replaces all msleep function calls with usleep_range calls
in the generic drivers.
Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a
thousand PCR extends, we see results going from 1m57s unpatched to 40s
with the new patch. We obtain similar results when using the original and
patched tpm_infineon driver, which is also part of the patch.
Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per
extend unpatched and around 7ms with the new patch.
Note that the PCR consistency is untouched with this patch, each TPM has
been tested with 10 million extends and the aggregated PCR value is
continuously verified to be correct.
As an extension of this work, this could potentially and easily be applied
to other vendor's drivers. Still, these changes are not included in the
proposed patch as they are untested.

- Fix an initialization time memory leak in cpuidle on ARM which
occurs if the cpuidle driver initialization fails (Stefan Wahren).
- Fix a PM core function that checks whether or not there are any
system suspend/resume callbacks for a device, but forgets to check
legacy callbacks which then may be skipped incorrectly and the
system may crash and/or the device may become unusable after a
suspend-resume cycle (Rafael Wysocki).

This patch fixes a memory leak issue when alloc_mr is used.
mr->pages and mr->npages are used only in alloc_mr path. mr->pages
is allocated when alloc_mr is called or in the case of FRMR, while
creating the MR. mr->npages is updated only when the MR created
is used i.e. after invoking map_mr_sg verb, before data transfer.
In the dereg_mr path, if mr->npages is 0, driver ends up not freeing
the memory created.
Removing the npages check from the dereg_mr path for kernel consumers.

When there is a NETDEV_UNREGISTER event, bnxt_re driver calls
ib_unregister_device() (RTNL lock held).
ib_unregister_device attempts to flush a worker queue scheduled by
ib_core and that queue might have a pending ib_query_port().
ib_query_port in turn calls bnxt_re_query_port(), which while querying the
link speed using ib_get_eth_speed(), tries to acquire the rtnl_lock() which
was already held by NETDEV_UNREGISTER.
Fixing the issue by removing the link speed query from bnxt_re_query_port()
Now the speed is queried post a successful ib_register_device or whenever
there is a NETDEV_CHANGE event.

Upon receipt of the NETDEV_REGISTER event from the netdev notifier chain,
the IB stack registration is spawned off to a workqueue since that also
requires an rtnl lock.
There could be 2 kinds of races between the NETDEV_REGISTER and the
NETDEV_UNREGISTER event handling.
a)The NETDEV_UNREGISTER event is received in rapid succession after
the NETDEV_REGISTER event even before the work queue got a chance to run.
b)The NETDEV_UNREGISTER event is received while the workqueue that handles
registration with the IB stack is still in progress.
Handle both the races with a bit flag that is set just before the work item
is queued and cleared in the workqueue after the event is handled just
before the workqueue item is freed.
While adding the new flag, it was noted that the flags are all used in
*_bit() operations which expect a bit number and not a literal constant
with a bit set. So change the numbers to be bit numbers.

Netdev event notifier registration/de-registration is not
synchronized with a lock and there is a possibility of a
duplicate registration of notifier before the unregister
completes.
Register netdev event notifiers during module init and
de-register them at module exit.
This avoids the need to tie the registration to first netdev
client interface open and de-registration to last client
interface close and the synchronization to achieve it.
This also fixes a crash due to duplicate registration.

If delay_drop_debugfs_init() fails in any of the operations to create
debugfs, it is calling delay_drop_debugfs_cleanup() as part of its
cleanup. But delay_drop_debugfs_cleanup() checks for 'dbg' and since
we have not yet pointed 'dbg' to the debugfs we need to cleanup, the
cleanup fails and we are left with stray debugfs elements and also a
memory leak.

In the case where mbox_status is OCRDMA_MBX_STATUS_FAILED and
add_status is OCRDMA_MBX_STATUS_FAILED err_num is assigned -EAGAIN
however the case OCRDMA_MBX_STATUS_FAILED is missing a break and
falls through to the default case which then re-assigns err_num
to -EFAULT. Fix this so that err_num is assigned to -EAGAIN
for the add_status OCRDMA_MBX_STATUS_FAILED case and -EFAULT
otherwise.

of_pci_iommu_init() tries to be clever and stop its alias walk at the
device represented by master_np, in case of weird PCI topologies where
the bridge to the IOMMU and the rest of the system is not at the root.
It turns out this is a bit short-sighted, since there are plenty of
other callers of pci_for_each_dma_alias() which would also need the same
behaviour in that situation, and the only platform so far with such a
topology (Cavium ThunderX2) already solves it more generally via a PCI
quirk. As this check is effectively redundant, and returning a boolean
value as an int is a bit broken anyway, let's just get rid of it.
