The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

The cdc-acm driver does not have a refcount of itself, but uses a
tty_port's refcount. That is, if the refcount of tty_port is '0', we
can clean up the cdc-acm driver by calling the .destruct()
callback function of struct tty_port_operations.

The problem is the destruct() callback function is not called if
the probe() fails, because tty_port's refcount is not zero. So,
add tty_port_put() when probe() fails.

When a USB device attached to a root-hub port sends a wakeup request
to a sleeping system, we do not report the wakeup event to the PM
core.  This is because a system resume involves waking up all
suspended USB ports as quickly as possible; without the normal
USB_RESUME_TIMEOUT delay, the host controller driver doesn't set the
USB_PORT_STAT_C_SUSPEND flag and so usb_port_resume() doesn't realize
that a wakeup request was received.

However, some environments (such as Chrome OS) want to have all wakeup
events reported so they can be ascribed to the appropriate device.  To
accommodate these environments, this patch adds a new routine to the
hub driver and a corresponding new HCD method to be used when a root
hub resumes.  The HCD method returns a bitmap of ports that have
initiated a wakeup signal but not yet completed resuming.  The hub
driver can then report to the PM core that the child devices attached
to these ports initiated a wakeup event.

Generic symbols and drivers without platform dependencies keep their

It is possible, under obscure circumstances, to convince the ITS driver to
emit a SYNC operation that targets a collection that is not bound to any
redistributor (and the target_address field is zero) because the
corresponding CPU has not been seen yet (the system has been booted with
max_cpus="something small").

If the ITS is using the linear CPU number as the target, this is not a big
deal, as we just end-up issuing a SYNC to CPU0. But if the ITS requires the
physical address of the redistributor (with GITS_TYPER.PTA==1), we end-up
asking the ITS to write to the physical address zero, which is not exactly
a good idea (there has been report of the ITS locking up). This should of
course never happen, but hey, this is SW...

In order to avoid the above disaster, let's track which collections have
been actually initialized, and let's not generate a SYNC if the collection
hasn't been properly bound to a redistributor.  Take this opportunity to
spit our a warning, in the hope that someone may report the issue if it
arrises again.

Commit:

  79832f0b ("efi/libstub/tpm: Initialize pointer variables to zero for mixed mode")

fixes a problem with the tpm code on mixed mode (64-bit kernel on 32-bit UEFI),
where 64-bit pointer variables are not fully initialized by the 32-bit EFI code.

A similar problem applies to the efi_physical_addr_t variables which
are written by the ->get_event_log() EFI call. Even though efi_physical_addr_t
is 64-bit everywhere, it seems that some 32-bit UEFI implementations only
fill in the lower 32 bits when passed a pointer to an efi_physical_addr_t
to fill.

This commit initializes these to 0 to, to ensure the upper 32 bits are
0 in mixed mode. This fixes recent kernels sometimes hanging during
early boot on mixed mode UEFI systems.

For passing arbitrary data from user land to the Xen hypervisor the
Xen tools today are using mlock()ed buffers. Unfortunately the kernel
might change access rights of such buffers for brief periods of time
e.g. for page migration or compaction, leading to access faults in the
hypervisor, as the hypervisor can't use the locks of the kernel.

In order to solve this problem add a new device node to the Xen privcmd
driver to easily allocate hypercall buffers via mmap(). The memory is
allocated in the kernel and just mapped into user space. Marked as
VM_IO the user mapping will not be subject to page migration et al.

nvme requires an sg table allocation for each request. If the request
is large, then the allocation can become quite large. For instance,
with our default software settings of 1280KB IO size, we'll need
10248 bytes of sg table. That turns into a 2nd order allocation,
which we can't always guarantee. If we fail the allocation, blk-mq
will retry it later. But there's no guarantee that we'll EVER be
able to allocate that much contigious memory.

Limit the IO size such that we never need more than a single page
of memory. That's a lot faster and more reliable. Then back that
allocation with a mempool, so that we know we'll always be able
to succeed the allocation at some point.

The race is between completing the request at error recovery work and

rdma completion we get a NULL deref of the request MR at
nvme_rdma_process_nvme_rsp().

When Canceling the request we return its mr to the mr pool (set mr to
NULL) and also unmap its data.  Canceling the requests while the rdma
queues are active is not safe.  Because rdma queues are active and we
get good rdma completions that can use the mr pointer which may be NULL.
Completing the request too soon may lead also to performing DMA to/from

Current ISH driver only registers suspend/resume PM callbacks which don't
support hibernation (suspend to disk). Basically after hiberation, the ISH
can't resume properly and user may not see sensor events (for example: screen

User will not see a crash or panic or anything except the following message
in log:

So this patch adds support for S4/hiberbation to ISH by using the
SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
and resume functions will now be used for both suspend to RAM and hibernation.

If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
and resume related functions won't be used, so mark them as __maybe_unused to
clarify that this is the intended behavior, and remove #ifdefs for power
management.

After commit 88078d98 ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE

message.

CHECKSUM_COMPLETE has in fact never worked for this driver, but this
was masked by the fact that upper stacks had to strip the FCS, and
therefore skb->ip_summed was set back to CHECKSUM_NONE before
my recent change.

Driver configures a number of bytes to skip when the chip computes
the checksum, and for some reason only half of the Ethernet header
was skipped.

Then a second problem is that we should strip the FCS by default,
unless the driver is updated to eventually support NETIF_F_RXFCS in
the future.

Finally, a driver should check if NETIF_F_RXCSUM feature is enabled
or not, so that the admin can turn off rx checksum if wanted.
