Regression tests showed that the CCA cipher key function which
generates an CCA cipher key with given clear key value does not work
correctly. At parsing the reply CPRB two limits are wrong calculated
resulting in rejecting the reply as invalid with s390dbf message
"_ip_cprb_helper reply with invalid or unknown key block".

Intel ID: PSIRT-TA-201910-001
CVEID: CVE-2019-14615
Intel GPU Hardware prior to Gen11 does not clear EU state
during a context switch. This can result in information
leakage between contexts.
For Gen8 and Gen9, hardware provides a mechanism for
fast cleardown of the EU state, by issuing a PIPE_CONTROL
with bit 27 set. We can use this in a context batch buffer
to explicitly cleardown the state on every context switch.
As this workaround is already in place for gen8, we can borrow
the code verbatim for Gen9.

Commit 85a8ce62c2 ("block: add bio_truncate to fix guard_bio_eod")
adds bio_truncate() for handling bio EOD. However, bio_truncate()
doesn't use the passed 'op' parameter from guard_bio_eod's callers.
So bio_trunacate() may retrieve wrong 'op', and zering pages may
not be done for READ bio.
Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs()
in submit_bh_wbc() so that bio_truncate() can always retrieve correct
op info.
Meantime remove the 'op' parameter from guard_bio_eod() because it isn't
used any more.

In the current implementation, final zone-mgmt request is issued with
submit_bio_wait() which marks the bio REQ_SYNC. This is needed since
immediate action is expected for zone-mgmt requests as these are
blocking operations. This also bypasses the scheduler in the
blk_mq_make_request() and dispatches the request directly into the
hw ctx.
This patch marks all the chained bios REQ_SYNC so that we can have
above-mentioned behavior for non-final bios also.
