Whenever the PAN (P2P) context is active, it
has timers in the uCode that prevent sleep,
so scanning can't be out of channel for more
than the beacon interval programmed into the
device.
Before this patch, a full scan including any
passive channels when P2P was active would
stall forever because it wouldn't find time
to execute the passive requests (for default
beacon intervals of 100 TU.)

Fix multiple bugs in event tracing:
1) If you enable uCode tracing with the device down,
it will still attempt to access the device and
continuously log "MAC is in deep sleep!" errors.
Fix this by only starting logging when the device
is actually alive.
2) Now you can set the flag when the device is down,
but logging doesn't happen when you bring it up.
To fix that, start logging when the device comes
alive. This means we don't log before -- we could
do that but I don't need it right now.
3) For some reason we read the error instead of the
event log -- use the right pointer.
4) Optimise SRAM reading of event log header.
5) Fix reading write pointer == capacity, which can
happen due to racy SRAM access
6) Most importantly: fix an error where we would try
to read WAY too many events (like 2^32-300) when
we read the wrap counter before it is updated by
the uCode -- this does happen in practice and will
cause the driver to hang the machine.
7) Finally, change the timer to 10ms instead of 100ms
as 100ms is too slow to capture all data with a
normal event log and with 100ms the log will wrap
multiple times before we have a chance to read it.

The ICT code erroneously uses PAGE_SIZE. The bug
is that PAGE_SIZE isn't necessarily 4096, so on
such platforms this code will not work correctly
as we'll try to attempt to read an index in the
table that the device never wrote, it always has
4096-byte pages.
Additionally, the manual alignment code here is
unnecessary -- Documentation/DMA-API-HOWTO.txt
states:
The cpu return address and the DMA bus master address are both
guaranteed to be aligned to the smallest PAGE_SIZE order which
is greater than or equal to the requested size. This invariant
exists (for example) to guarantee that if you allocate a chunk
which is smaller than or equal to 64 kilobytes, the extent of the
buffer you receive will not cross a 64K boundary.
Just use appropriate new constants and get rid of
the alignment code.
