sys/dev/ic : mpi.c mpireg.h
Log message:
mpi scatter gather lists are 24 bytes long and next to each other in
memory. that means you cant do 8 byte loads and stores on the sg_addr
member cos it wont be 8 byte aligned half the time which makes
strict alignment archs (ie, the fun ones ones) upset.
annotate the sge as being 4 byte aligned. replace the sg_addr member
with sg_addr_lo and sg_addr_hi.
replace htole64 assignment of the sg addr with a wrapper that does
the right thing with a couple of htolem32 calls.
generated code shrinks again.
