in linux below patches remove the support for QUEUE_FLAG_DISCARD

block: remove QUEUE_FLAG_DISCARD
Just use a non-zero max_discard_sectors as an indicator for discard
support, similar to what is done for write zeroes.
The only places where needs special attention is the RAID5 driver,
which must clear discard support for security reasons by default,
even if the default stacking rules would allow for it.

block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD
Secure erase is a very different operation from discard in that it is
a data integrity operation vs hint. Fully split the limits and helper
infrastructure to make the separation more clear.

The ivc.h is not protected for multiple inclusion and so
it is generating error for multiple definition when included
from the source code.
Add wrapper header to protect the multiple inclusion of the ivc.h.
This will make the OOT driers to compile against all core kernel
which does not have proper ivc.h fix.
