RDMA/cma: Fix deadlock destroying listen requests
Deadlock condition reported by Kanoj Sarcar <kanoj@netxen.com>.
The deadlock occurs when a connection request arrives at the same
time that a wildcard listen is being destroyed.
A wildcard listen maintains per device listen requests for each
RDMA device in the system. The per device listens are automatically
added and removed when RDMA devices are inserted or removed from
the system.
When a wildcard listen is destroyed, rdma_destroy_id() acquires
the rdma_cm's device mutex ('lock') to protect against hot-plug
events adding or removing per device listens. It then tries to
destroy the per device listens by calling ib_destroy_cm_id() or
iw_destroy_cm_id(). It does this while holding the device mutex.
However, if the underlying iw/ib CM reports a connection request
while this is occurring, the rdma_cm callback function will try
to acquire the same device mutex. Since we're in a callback,
the ib_destroy_cm_id() or iw_destroy_cm_id() calls will block until
their callback thread returns, but the callback is blocked waiting for
the device mutex.
Fix this by re-working how per device listens are destroyed. Use
rdma_destroy_id(), which avoids the deadlock, in place of
cma_destroy_listen(). Additional synchronization is added to handle
device hot-plug events and ensure that the id is not destroyed twice.

RDMA/cma: Add locking around QP accesses
If a user allocates a QP on an rdma_cm_id, the rdma_cm will automatically
transition the QP through its states (RTR, RTS, error, etc.) While the
QP state transitions are occurring, the QP itself must remain valid.
Provide locking around the QP pointer to prevent its destruction while
accessing the pointer.
This fixes an issue reported by Olaf Kirch from Oracle that resulted in
a system crash:
"An incoming connection arrives and we decide to tear down the nascent
connection. The remote ends decides to do the same. We start to shut
down the connection, and call rdma_destroy_qp on our cm_id. ... Now
apparently a 'connect reject' message comes in from the other host,
and cma_ib_handler() is called with an event of IB_CM_REJ_RECEIVED.
It calls cma_modify_qp_err, which for some odd reason tries to modify
the exact same QP we just destroyed."

HID: add hidraw interface
hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

suppose NOR flash for simplicity. If an "atomic LEB change operation"
is run, and the WL unit is moving a LEB, we have no spare LEBs to
finish the operation and fail, which is not good. Moreover, if there
are 2 or more simultanious "atomic LEB change" requests, only one of
them has chances to succeed, the other will fail with -ENOSPC. Not
good either.

We were simply concatenating the devhandle and devino and using that
as the cookie, which defeats the entire purpose of the VIRQ hypervisor
interfaces.
Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket). This allows us to test for and decode the cookie with
a simple:
brlz $reg1, 1f
xnor $reg1, %g0, $reg2
sequence.
This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address. So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.
