Commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate
kernel's notifier object at end of block") intended to align end of
notifier block to page boundary, but start of block was miscalculated
to be off by -16 bytes. Fix it.

nouveau_bo_wr32 expects offset to be in words, but we pass value in bytes,
so after commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate
kernel's notifier object at end of block") we started to overwrite some memory
after notifier buffer object (previously m2mf_ntfy was always 0, so it didn't
matter it was a value in bytes).

This patch fixes two issues:
- A disabled crtc does not use any lb, so return 0 for
lb size. This makes the display priority calculation
more exact.
- Only use 1/2 and whole lb partitions. Using smaller
partitions can cause underflow to one of the displays
if you have multiple large displays on the same lb.

Sometimes the i2c test in i2c_bit_add_bus fails
if this happens we fail to register the i2c adapter and
eventually fail to add the connector. If i2c fails,
add the connector to the user can at least force
it on.
Note that some distros set i2c-algo-bit.bit_test to 1 by
default which sometimes fails preventing the ddc i2c adapter
from being added. The i2c adapter works even if the bit test
fails, probably due to pre/post_xfer not getting called in
the test_bit function. I have another patch to follow
up on that.

Change vddci as well as vddc when changing power modes
on evergreen/ni. Also, properly set vddci on boot up
for ni cards. The vbios only sets the limited clocks
and voltages on boot until the mc ucode is loaded. This
should fix stability problems on some btc cards.

As per Konrad's original patch, the dummy page used
by the gart code and allocated in radeon_gart_init()
was not freed properly in radeon_gart_fini().
At the same time r6xx and newer allocated and freed the
dummy page on their own. So to do Konrad's patch one
better, just remove the allocation and freeing of the
dummy page in the r6xx, 7xx, evergreen, and ni code and
allocate and free in the gart_init/fini() functions for
all asics.

It has been reported that this greatly improves (and possibly fixes
completely) the stability of NVA3+ chipsets. In traces of my NVA8,
NVIDIA now appear to be doing this too.
The most recent traces of 0x50 and 0xac I could find don't show NVIDIA
checking PGRAPH status on these flushes, so for now, we won't either.

The latest binutils won't accept the stfl instruction with march=g5
which is the correct behaviour. Unfortunately head.S is assembled
with -march=g5 even if the target cpu is z900 or later. To get
31-bit kernels compiled again the easiest fix is to use the .insn
notation for the stfl instruction in head.S.

The cio_ignore purge function is intended to only remove CCW devices
which are in the offline state. There is a time frame after the purge
function finished where a CCW device is scheduled for removal but
still accessible. When the device is set online during this time
frame, it may first appear online before it is then removed.
Fix this by preventing that CCW devices can be set online while there
is work (such as removal triggered by the purge function) for it
pending. Also ensure that the purge function does not schedule devices
for removal which are in the process of being set online.

After the execution has been switched to the destination CPU, the target
function is called with the wrong parameter. According to the C calling
convention on s390, the first parameter should be loaded into register 2.
Currently in smp_restart_cpu() it is stored in register 3. To fix this, we
load the parameter into the correct register 2.

quota: Don't write quota info in dquot_commit()

There's no reason to write quota info in dquot_commit(). The writing is a
relict from the old days when we didn't have dquot_acquire() and
dquot_release() and thus dquot_commit() could have created / removed quota
structures from the file. These days dquot_commit() only updates usage counters
/ limits in quota structure and thus there's no need to write quota info.
This also fixes an issue with journaling filesystem which didn't reserve
enough space in the transaction for write of quota info (it could have been
dirty at the time of dquot_commit() because of a race with other operation
changing it).
