3 uapi header files(mxc_sim_interface.h, pxp_dma.h, pxp_device.h)
cannot be installed by the command "make headers_install" because
they are not in Kbuild list, which impacts the linux-test build.
This patch adds the 3 header files in Kbuild list.

This driver is based on the current code which runs the the EMV test on the i.MX258 platform.
Since there are still many cases that can't pass on the i.MX258 and i.MX7d platform. The
driver will need to be improved after per-test work. Just check in as a base code. There
would be definitly some timing improvement work to do in the future.

09a2c73ddfc7 ("PCI: Remove unused PCI_MSIX_FLAGS_BIRMASK definition")
removed PCI_MSIX_FLAGS_BIRMASK from an exported header because it was
unused in the kernel. But that breaks user programs that were using it
(QEMU in particular).

commit 648a9bc5308d952f2c80772301b339f73026f013 upstream.
Since the hardware sometimes mysteriously totally flummoxes the 64bit
read of a 64bit register when read using a single instruction, split the
read into two instructions. Since the read here is of automatically
incrementing timestamp counters, we also have to be very careful in
order to make sure that it does not increment between the two
instructions.
However, since userspace tried to workaround this issue and so enshrined
this ABI for a broken hardware read and in the process neglected that
the read only fails in some environments, we have to introduce a new
uABI flag for userspace to request the 2x32 bit accurate read of the
timestamp.
v2: Fix alignment check and include details of the workaround for
userspace.

In compliance with RFC5961, the network stack send challenge ACK in
response to spurious SYN packets, since commit 0c228e833c88 ("tcp:
Restore RFC5961-compliant behavior for SYN packets").
This pose a problem for netfilter conntrack in state LAST_ACK, because
this challenge ACK is (falsely) seen as ACKing last FIN, causing a
false state transition (into TIME_WAIT).
The challenge ACK is hard to distinguish from real last ACK. Thus,
solution introduce a flag that tracks the potential for seeing a
challenge ACK, in case a SYN packet is let through and current state
is LAST_ACK.
When conntrack transition LAST_ACK to TIME_WAIT happens, this flag is
used for determining if we are expecting a challenge ACK.

Some Congestion Control modules can provide per flow information,
but current way to get this information is to use netlink.
Like TCP_INFO, let's add TCP_CC_INFO so that applications can
issue a getsockopt() if they have a socket file descriptor,
instead of playing complex netlink games.
Sample usage would be :
union tcp_cc_info info;
socklen_t len = sizeof(info);
if (getsockopt(fd, SOL_TCP, TCP_CC_INFO, &info, &len) == -1)

getsockopt() if one has a handle on a TCP socket, or from inet_diag

Pull md updates from Neil Brown:
"More updates that usual this time. A few have performance impacts
which hould mostly be positive, but RAID5 (in particular) can be very
work-load ensitive... We'll have to wait and see.
Highlights:
- "experimental" code for managing md/raid1 across a cluster using
DLM. Code is not ready for general use and triggers a WARNING if
used. However it is looking good and mostly done and having in
mainline will help co-ordinate development.
- RAID5/6 can now batch multiple (4K wide) stripe_heads so as to
handle a full (chunk wide) stripe as a single unit.
- RAID6 can now perform read-modify-write cycles which should help
performance on larger arrays: 6 or more devices.
- RAID5/6 stripe cache now grows and shrinks dynamically. The value
set is used as a minimum.
- Resync is now allowed to go a little faster than the 'mininum' when
there is competing IO. How much faster depends on the speed of the
devices, so the effective minimum should scale with device speed to
some extent"

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs update from Dave Chinner:
"This update contains:
- RENAME_WHITEOUT support
- conversion of per-cpu superblock accounting to use generic counters
- new inode mmap lock so that we can lock page faults out of
truncate, hole punch and other direct extent manipulation functions
to avoid racing mmap writes from causing data corruption
- rework of direct IO submission and completion to solve data
corruption issue when running concurrent extending DIO writes.
Also solves problem of running IO completion transactions in
interrupt context during size extending AIO writes.
- FALLOC_FL_INSERT_RANGE support for inserting holes into a file via
direct extent manipulation to avoid needing to copy data within the
file
- attribute block header field overflow fix for 64k block size
filesystems
- Lots of changes to log messaging to be more informative and concise
when errors occur. Also prevent a lot of unnecessary log spamming
due to cascading failures in error conditions.
- lots of cleanups and bug fixes
One thing of note is the direct IO fixes that we merged last week
after the window opened. Even though a little late, they fix a user
reported data corruption and have been pretty well tested. I figured
there was not much point waiting another 2 weeks for -rc1 to be
released just so I could send them to you..."

NFS: NFSoRDMA Client Changes
This patch series creates an operation vector for each of the different
memory registration modes. This should make it easier to one day increase
credit limit, rsize, and wsize.

This file is only used internally to the NFS v4 module, so it doesn't
need to be in the global include path. I also renamed it from
nfs_idmap.h to nfs4idmap.h to emphasize that it's an NFSv4-only include
file.

Commit f895b252d4edf ("sunrpc: eliminate RPC_DEBUG") introduced
use of IS_ENABLED() in a uapi header which leads to a build
failure for userspace apps trying to use <linux/nfsd/debug.h>:
linux/nfsd/debug.h:18:15: error: missing binary operator before token "("
#if IS_ENABLED(CONFIG_SUNRPC_DEBUG)
^
Since this was only used to define NFSD_DEBUG if CONFIG_SUNRPC_DEBUG
is enabled, replace instances of NFSD_DEBUG with CONFIG_SUNRPC_DEBUG.
