This series of patches fixes two bugs that are triggered when the input data is
too large. The first one is caused by the miscalculation of physical addresses
and the second one by some limits that the co-processor has to the input data.
Changes in v2:
* Replace Signed-Off-By tags with
The co-processor receives data to be hashed through scatter/gather lists
pointing to physical addresses. When a vmalloc'ed data is given, the
driver must calculate the physical address to each page of the data.
However the current version of it just calculates the physical address
once and keeps
The co-processor has several limits regarding the length of
scatter/gather lists and the total number of bytes in it. These limits
are available in the device tree, as following:
- ibm,max-sg-len: maximum number of bytes of each scatter/gather
list.
- ibm,max-sync-cop: used for synchronous
