powerpc/rtas: ensure 8-byte alignment for struct rtas_args ...
CHRP and PAPR agree: "In order to make an RTAS call, the operating
system must construct an argument call buffer aligned on an eight byte
boundary in physically contiguous real memory [...]." (7.2.7 Calling
Mechanism and Conventions).
struct rtas_args is the type used for this argument call buffer. The
unarchitected 'rets' member happens to produce 8-byte alignment for
the struct on 64-bit targets in practice. But without an alignment
directive the structure will have only 4-byte alignment on 32-bit
targets:
$ nm b/{before,after}/chrp32/vmlinux | grep rtas_args
c096881c b rtas_args
c0968820 b rtas_args
Add an alignment directive to the struct rtas_args declaration so all
instances have the alignment required by the specs. rtas-types.h no
longer refers to any spinlock types, so drop the spinlock_types.h
inclusion while we're here.
