[ Upstream commit 7ccc1465465d78e6411b7bd730d06e7435802b5c ]
Call cifs_reconnect() to wake up processes waiting on negotiate
protocol to handle the case where server abruptly shut down and had no
chance to properly close the socket.
Simple reproducer:
ssh 192.168.2.100 pkill -STOP smbd
mount.cifs //192.168.2.100/test /mnt -o ... [never returns]

[ Upstream commit d3e154d7776ba57ab679fb816fb87b627fba21c9 ]
This reverts commit 7f0343b7b8710436c1e6355c71782d32ada47e0c.
We are going to revert commit 166a490f59ac ("wifi: ath11k: support hibernation"), on
which this commit depends. With that commit reverted, this one is not needed any
more, so revert this commit first.

[ Upstream commit 258905cb9a6414be5c9ca4aa20ef855f8dc894d4 ]
We use komeda_crtc_normalize_zpos to normalize zpos of affected planes
to their blending zorder in CU. If there's only one slave plane in
affected planes and its layer_split property is enabled, order++ for
its split layer, so that when calculating the normalized_zpos
of master planes, the split layer of the slave plane is included, but
the max_slave_zorder does not include the split layer and keep zero
because there's only one slave plane in affacted planes, although we
actually use two slave layers in this commit.
In most cases, this bug does not result in a commit failure, but assume
the following situation:
slave_layer 0: zpos = 0, layer split enabled, normalized_zpos =
0;(use slave_layer 2 as its split layer)
master_layer 0: zpos = 2, layer_split enabled, normalized_zpos =
2;(use master_layer 2 as its split layer)
master_layer 1: zpos = 4, normalized_zpos = 4;
master_layer 3: zpos = 5, normalized_zpos = 5;
kcrtc_st->max_slave_zorder = 0;
When we use master_layer 3 as a input of CU in function
komeda_compiz_set_input and check it with function
komeda_component_check_input, the parameter idx is equal to
normailzed_zpos minus max_slave_zorder, the value of idx is 5
and is euqal to CU's max_active_inputs, so that
komeda_component_check_input returns a -EINVAL value.
To fix the bug described above, when calculating the max_slave_zorder
with the layer_split enabled, count the split layer in this calculation
directly.
