When char is signed and one of the bytes in lmm happens to have a byte
value above 127, the result of printing that with %.2X will be 8 hex
chars, the first 6 of which are 'F'. Worst case, we'll overrun our
'carefully' allocated buffer.
I didn't have the tenacity to work through the gazillion and seven
layers of macros behind CERROR, but I assume it'll all end at some
function implemented in terms of the kernel's vsnprintf. Use %*phN for
a hexdump. That'll cap the number of dumped bytes at 64. If that's a
problem, the loop could be replaced by "bin2hex(buffer, lmm,

staging/rdma/hfi1: convert buffers allocated atomic to per cpu
Profiling has shown the the atomic is a performance issue
for the pio hot path.
If multiple cpus allocated an sc's buffer, the cacheline
containing the atomic will bounce from L0 to L0.
Convert the atomic to a percpu variable.

staging/rdma/hfi1: fix pio progress routine race with allocator
The allocation code assumes that the shadow ring cannot
be overrun because the credits will limit the allocation.
Unfortuately, the progress mechanism in sc_release_update() updates
the free count prior to processing the shadow ring, allowing the
shadow ring to be overrun by an allocation.

staging/rdma/hfi1: Add page lock limit check for SDMA requests
The driver pins pages on behalf of user processes in two
separate instances - when the process has submitted a
SDMA transfer and when the process programs an expected
receive buffer.
When pinning pages, the driver is required to observe the
locked page limit set by the system administrator and refuse
to lock more pages than allowed. Such a check was done for
expected receives but was missing from the SDMA transfer
code path.
This commit adds the missing check for SDMA transfers. As of
this commit, user SDMA or expected receive requests will be
rejected if the number of pages required to be pinned will
exceed the set limit.
Due to the fact that the driver needs to take the MM semaphore
in order to update the locked page count (which can sleep), this
cannot be done by the callback function as it [the callback] is
executed in interrupt context. Therefore, it is necessary to put
all the completed SDMA tx requests onto a separate list (txcmp) and
offload the actual clean-up and unpinning work to a workqueue.

staging/rdma/hfi1: Fix downgrade race
A link downgrade can race with link up. Avoid the race
in two ways. First, by having the downgrade application logic
take the link state mutex for all of its checking. Second, by
waiting for the link to move out of the going up state.

android: unconditionally remove callbacks in sync_fence_free()
Using fence->status to determine whether or not there are callbacks
remaining on the sync_fence is racy since fence->status may have been
decremented to 0 on another CPU before fence_check_cb_func() has
completed. By unconditionally calling fence_remove_callback() for each
fence in the sync_fence, we guarantee that each callback has either
completed (since fence_remove_callback() grabs the fence lock) or been
removed.
