Subject: [RFC-PATCH] ieee1394: endian annotations of drivers/ieee1394
Annotations are mostly trivial, quadlet_t -> __be32, octlet_t -> __be64
which will have no effect on compiled code.
Changed the protoypes of the read_regs, write_regs, lock_regs, lock64_regs
to take BE values rather than quadlet/octlet...propagated this through
helper functions.
csr.c: work directly with the BE values in the lock functions and only
convert to cpu-endian on demand, this part is non-trivial, but pretty
easy to verify. Introduce a few temporary variables to make in clear
we are in cpu-endianness in a few cases. Also, remove a few macros
that were used only once and obscured what was actually happening when
setting the type and generation...this eliminated some gratuitous
byteswapping back and forth between cpu and big endian.
sbp.c: Eliminate the in-place be32-to-cpu inline which was only used once
and do the conversion once in the places where each struct member is set/read,
this propagates into one helper function that also now works directly in
be32.
Also eliminate a few of the calls to the cpu-to-be32 that swapped a constant
8 bytes and set the struct members directly as be32 values.
dv1394.c is the only place where a change in behavior is intentional, the
setting of the flags is done as cpu-endian where everwhere else it is done
as little-endian, see the potion of the diff in ir_tasklet_func()
The rest of the changes end up being pretty simple annotations of struct
members that were always treated as a particular endianness, mark them as
such.
