Summary
scsi: lpfc: Revise lpfc_prep_embed_io routine with proper endian macro usages
Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Revise lpfcprepembed_io routine with proper endian macro usages

On big endian architectures, it is possible to run into a memory out of bounds pointer dereference when FCP targets are zoned.

In lpfcprepembedio, the memcpy(ptr, fcpcmnd, sgl->sgelen) is referencing a little endian formatted sgl->sgelen value. So, the memcpy can cause big endian systems to crash.

Redefine the *sgl ptr as a struct sli4sgele to make it clear that we are referring to a little endian formatted data structure. And, update the routine with proper le32tocpu macro usages.
