The new auditing standard for the subsystem will be to only use
__aligned_64 in uapi headers to try and prevent 32/64 compat bugs
from existing in the future.
Changing all existing usage will help ensure new developers copy the
right idea.
The before/after of this patch was tested using pahole on 32 and 64
bit compiles to confirm it has no change in the structure layout, so
this patch is a NOP.

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

Move hfi1 ioctl definitions to a new header which can be included by
both the hfi1 and qib drivers to avoid a duplicate enum definition
as shown in this build error for qib:
CC [M] drivers/infiniband/hw/qib/qib_sysfs.o
In file included from ./include/uapi/rdma/rdma_user_ioctl.h:39:0,

./include/uapi/rdma/hfi/hfi1_user.h:370:2: error: redeclaration of
enumerator ‘ur_rcvhdrtail’
ur_rcvhdrtail = 0,
Move hfi1 structures to separate file to avoid this failure.
The actual move of the ioctl definitions comes in a follow on patch.
