911a472aca ARM: shmobile: Fix build problem in pm-sh7372.c for unusual .config
If neither CONFIG_SUSPEND nor CONFIG_CPU_IDLE is set in the kernel
configuration file, build error occurs in
arch/arm/mach-shmobile/pm-sh7372.c.

Fix it by rearranging #ifdefs in that file to make the
definition of sh7372_suspend_init() depend only on
CONFIG_SUSPEND and the definition of sh7372_cpuidle_init()
depend only on CONFIG_CPU_IDLE.

a1ee61b8f4 ARM: shmobile: Take cpuidle dependencies into account correctly
The sh7372's cpuidle code uses cpu_suspend() and cpu_resume() in
its implementation of the .enter() callback for deeper C-states, so
make ARCH_SH7372 select ARM_CPU_SUSPEND if CPU_IDLE is set to satisfy
all of the build dependencies (it has to be selected for CONFIG_PM
as well for the system suspend handling).

bbf43dc888 sunrpc/cache.h: replace simple_strtoul
This patch replaces the usage of simple_strtoul with kstrtoint in
get_int(), since the simple_str* family doesn't account for overflow
and is deprecated.
Also, in this specific case, the long from strtol is silently converted
to an int by the caller.

As Joe Perches <joe@perches.com> suggested, this patch also removes
the redundant temporary variable rv, since kstrtoint() will not write to
anint unless it's successful.

bce5bbbb23 arch/tile: provide kernel support for the tilegx TRIO shim
Provide kernel support for the tilegx "Transaction I/O" (TRIO) on-chip
hardware.  This hardware implements the PCIe interface for tilegx;
the driver changes to use TRIO for PCIe are in a subsequent commit.

The change is layered on top of the tilegx GXIO IORPC subsystem.

4875f69fec arch/tile: provide kernel support for the tilegx mPIPE shim
The TILE-Gx chip includes a packet-processing network engine called
mPIPE ("Multicore Programmable Intelligent Packet Engine").  This
change adds support for using the mPIPE engine from within the
kernel.  The engine has more functionality than is exposed here,
but to keep the kernel code and binary simpler, this is a subset
of the full API designed to enable standard Linux networking only.

37b82b5de7 arch/tile: introduce GXIO IORPC framework for tilegx
The GXIO I/O RPC subsystem handles exporting I/O hardware resources to
Linux and to applications running under Linux.

For instance, memory which is made available for I/O DMA must be mapped
by an I/O TLB; that means that such memory must be locked down by Linux,
so that it is not swapped or otherwise reused, as long as those I/O
TLB entries are active. Similarly, configuring direct hardware access
introduces new validation requirements. If a user application registers
memory, Linux must ensure that the supplied virtual addresses are valid,
and turn them into client physical addresses. Similarly, when Linux then
supplies those client physical addresses to the Tilera hypervisor, it
must in turn validate those before turning them into the real physical
addresses which are required by the hardware.

To the extent that these sorts of activities were required on previous
TILE architecture processors, they were implemented in a device-specific
fashion. This meant that every I/O device had its own Tilera hypervisor
driver, its own Linux driver, and in some cases its own user-level
library support. There was a large amount of more-or-less functionally
identical code in different places, particularly in the different Linux
drivers. For TILE-Gx, this support has been generalized into a common
framework, known as the I/O RPC framework or just IORPC.

The two "gxio" directories (one for headers, one for sources) start
with just a few files in each with this infrastructure commit, but
after adding support for the on-board I/O shims for networking, PCI,
USB, crypto, compression, I2CS, etc., there end up being about 20 files
in each directory.

More information on the IORPC framework is in the <hv/iorpc.h> header,
included in this commit.

8a76e5383f media: mx2_camera: Fix mbus format handling
Do not use MX2_CAMERA_SWAP16 and MX2_CAMERA_PACK_DIR_MSB flags. The driver
must negotiate with the attached sensor whether the mbus format is UYUV or
YUYV and set CSICR1 configuration accordingly.

This is needed for the video function on mach-imx27_visstrim_m10.c to
perform properly, since an earlier version of this patch has been proven
wrong and has been reverted and a commit, depending on it: "[media]
i.MX27: visstrim_m10: Remove use of MX2_CAMERA_SWAP16" is in the mainline.

c9122c0d63 carl9170: fix HT peer BA session corruption
This patch adds an alternative tx status path
for BlockAck Requests as the hardware doesn't
recognize that a BlockAck Requests is usually
acked with a BlockAck and not a legacy ACK.

Without this patch, the stack would constantly
resent old and stale BARs. So, depending on the
receiver stack, this could lead to:

 - "stuck" ba sessions and package loss, as the
   stale BAR would reset the sequence each time.

 - lots of reorder releases.

6634961c14 mlx4: Put physical GID and P_Key table sizes in mlx4_phys_caps struct and paravirtualize them
To allow easy paravirtualization of P_Key and GID table sizes, keep
paravirtualized sizes in mlx4_dev->caps, but save the actual physical
sizes from FW in struct: mlx4_dev->phys_cap.

In addition, in SR-IOV mode, do the following:

1. Reduce reported P_Key table size by 1.
   This is done to reserve the highest P_Key index for internal use,
   for declaring an invalid P_Key in P_Key paravirtualization.
   We require a P_Key index which always contain an invalid P_Key
   value for this purpose (i.e., one which cannot be modified by
   the subnet manager).  The way to do this is to reduce the
   P_Key table size reported to the subnet manager by 1, so that
   it will not attempt to access the P_Key at index #127.

2. Paravirtualize the GID table size to 1. Thus, each guest sees
   only a single GID (at its paravirtualized index 0).

In addition, since we are paravirtualizing the GID table size to 1, we
add paravirtualization of the master GID event here (i.e., we do not
do ib_dispatch_event() for the GUID change event on the master, since
its (only) GUID never changes).

105c320f6a mlx4_core: Allow guests to have IB ports
Modify mlx4_dev_cap to allow IB support when SR-IOV is active.  Modify
mlx4_slave_cap to set the "rdma-supported" bit in its flags area, and
pass that to the guests (this is done in QUERY_FUNC_CAP and its
wrapper).

However, we don't activate IB support quite yet -- we leave the error
return at the start of mlx4_ib_add in the mlx4_ib driver.

In addition, set "protected fmr supported" bit to zero in the
QUERY_FUNC_CAP wrapper.

Finally, in the QUERY_FUNC_CAP wrapper, we needed to add code which
checks for the port type (IB or Ethernet).  Previously, this was not
an issue, since only Ethernet ports were supported.

396f2feb05 mlx4_core: Implement mechanism for reserved Q_Keys
The SR-IOV special QP tunneling mechanism uses proxy special QPs
(instead of the real special QPs) for MADs on guests.  These proxy QPs
send their packets to a "tunnel" QP owned by the master.  The master
then forwards the MAD (after any required paravirtualization) to the
real special QP, which sends out the MAD.

For security reasons (i.e., to prevent guests from sending MADs to
tunnel QPs belonging to other guests), each proxy-tunnel QP pair is
assigned a unique, reserved, Q_Key.  These Q_Keys are available only
for proxy and tunnel QPs -- if the guest tries to use these Q_Keys
with other QPs, it will fail.

This patch introduces a mechanism for reserving a block of 64K Q_Keys
for proxy/tunneling use.

The patch introduces also two new fields into mlx4_dev: base_sqpn and
base_tunnel_sqpn.

In SR-IOV mode, the QP numbers for the "real," proxy, and tunnel sqps
are added to the reserved QPN area (so that they will not change).
There are 8 special QPs per port in the HCA, and each of them is
assigned both a proxy and a tunnel QP, for each VF and for the PF as
well in SR-IOV mode.

The QPNs for these QPs are arranged as follows:
 1. The real SQP numbers (8)
 2. The proxy SQPs (8 * (max number of VFs + max number of PFs)
 3. The tunnel SQPs (8 * (max number of VFs + max number of PFs)

To support these QPs, two new fields are added to struct mlx4_dev:

  base_sqp:  this is the QP number of the first of the real SQPs
  base_tunnel_sqp: this is the qp number of the first qp in the tunnel
                   sqp region. (On guests, this is the first tunnel
                   sqp of the 8 which are assigned to that guest).

In addition, in SR-IOV mode, sqp_start is the number of the first
proxy SQP in the proxy SQP region.  (In guests, this is the first
proxy SQP of the 8 which are assigned to that guest)

Note that in non-SR-IOV mode, there are no proxies and no tunnels.
In this case, sqp_start is set to sqp_base -- which minimizes code
changes.

 - Export devm_gpio_request_one() so it can be used in modules.
   Apparently some in-kernel modules can be configured to use this
   leading to breakage.
