Not removing pm qos request and free memory for it can cause crash,

commit 232a6ee9af upstream.
Add new definitions for hotplug live status bits for VLV2 since they're
in reverse order from the gen4x ones.
Changelog:
- Restored gen4 bit definitions
- Added new definitions for VLV2
- Added platform check for IS_VALLEYVIEW() in dp_detect to use the correct
bit defintions
- Replaced a lost trailing brace for the added switch()

[danvet: Switch to _VLV postfix instead of prefix and regroupg

Also add a _G4X suffix for those special ones. Also cc stable.]

commit ec14ba4779 upstream.
The 'offset' field of the 'scatterlist' structure was wrongly
programmed with the offset value from the base of stolen area,
whereas this field indicates the offset from where the interested
data starts within the first PAGE pointed to by 'scattterlist'
structure. As a result when a new GEM object allocated from stolen
area is mapped to GTT, it could lead to an overwrite of GTT entries
as the page count calculation will go wrong, refer the function
'sg_page_count'.
v2: Modified the commit message. (Chris)

commit 304d695c3d upstream.
In very rare cases (such as a memory failure stress test) it is possible
to fill the entire ring without emitting a request. Under this
circumstance, the outstanding request is flushed and waited upon. After
space on the ring is cleared, we return to emitting the new command -
except that we just cleared the seqno allocated for this operation and
trigger the sanity check that a request is only ever emitted with a
valid seqno. The fix is to rearrange the code to make sure the
allocation of the seqno for this operation is after any required flushes
of outstanding operations.
The bug exists since the preallocation was introduced in
commit 9d7730914f

commit 5d2f4767c4 upstream.
The only BIOS on record that needs the 14 offset has a bios major
version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18
offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the
bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.
