MIP_ADDRESS should point to the resolved FMASK for an MSAA texture.
Setting MIP_ADDRESS to 0 means the FMASK pointer is invalid (the GPU
won't read the memory then).
The userspace has to set MIP_ADDRESS to 0 and *not* emit any relocation
for it.

PDE/PTE update code uses CP ring for memory writes.
All page table entries are preallocated for now in alloc_pt().
It is made as whole because it's hard to divide it to several patches
that compile and doesn't break anything being applied separately.
Tested on cayman card.
v2: rebased on top of "refactor set_page chipset interface v3",
code cleanups
v3: switched offsets calc macros to inline funcs where possible,
remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define,
to 9 (and PTE_COUNT to 1 << BLOCK_SIZE)
v4 (ck): move "incr" documentation to previous patch, cleanup and
document RADEON_VM_* constants, change commit message to
our usual format, simplify patch allot by removing
everything current not necessary, disable SI workaround.
v5: (agd5f): Fix typo in tables_size calculation in
radeon_vm_alloc_pt(). Second line should have been
'+=' rather than '='.
v6: fix npdes calculation. In scenario when pfns to be mapped overlap
two PDE spans:
+-----------+-------------+
| PDE span | PDE span |
+-----------+----+--------+
| |
+---------+
| pfns |
+---------+
the following npdes calculation gives incorrect result:
npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1;
For the case above picture it should give npdes = 2, but gives one.
This patch corrects it by rounding last pfn up to 512 border,
first - down to 512 border and then subtracting and dividing by 512.
v7: Make npde calculation clearer, fix ndw calculation.
v8: (agd5f): reserve enough for 2 full VM PTs, add some
additional comments.
v9: fix typo in npde calculation

Since the current KMS API sets the mode independantly on
each crtc, we may end up with resource conflicts. The PLL
allocation is one of those cases. In the following example
we have 3 crtcs in use driving 2 DVI connectors and 1 DP
connector. On the initial kernel modeset for fbdev, the
display topology ends up as follows:
crtc0 -> DP-0
crtc1 -> DVI-0
crtc2 -> DVI-1
Because this is the first modeset, all of the PLLs are
available as none have been assigned. So we end up with
the following:
crtc0 uses DCPLL
crtc1 uses PPLL2
crtc2 uses PPLL1
When X starts, it assigns a different topology:
crtc0 -> DVI-0
crtc1 -> DP-0
crtc2 -> DVI-1
However, since the KMS API is per crtc, we set the mode on each
crtc independantly. When it comes time to set the mode on crtc0,
the topology for crtc1 and crtc2 are still intact. crtc1 and
crtc2 are already assigned PPLL2 and PPLL1 so when it comes time
to set the mode on crtc0, crtc1 and crtc2 have not been torn down
yet, so there appears to be no PLLs available. In reality, we
are reconfiguring the entire display topology, however, since
each crtc is handled independantly, we don't know that in the
driver at each crtc mode set time.
This patch checks to see if the same connector is being driven by
another crtc, and if so, uses the PLL already associated with it.
v2: store connector in the radeon crtc struct, simplify checking.

wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.
Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.
Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

The current elp timeout (the same as the dynamic
ps timeout - 1500ms) is too high. Usually,
wl1271_ps_elp_sleep() get called right after tx/rx,
which is fine, but some command might get sent
even when there is no traffic (e.g. ht changes
triggered by beacon frames), and leaving the
device awake for 1500ms in this case is redundant.
Use a timeout of 30ms.
The fw won't enter elp anyway before the dynamic-ps
timeout was expired as well (and it entered ps
successfully).

Previously, invalidation of the keep-alive template was
done when going idle. However, while removing the
idle-handling we didn't move the keep-alive template
invalidation to another place.
This finally resulted in fw error when trying to use
the keep-alive template by another role.
(Note that we still have an error here - each role
should have its unique keep-alive template id, while
currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0).
This only works now because we don't support concurrent
connected stations yet)

While recursive recovery is avoided during shutdown, a new recovery may
