This driver can be used on Xilinx ARM Zynq platform
where in_be32/out_be32 functions are not implemented.
Use __raw_readl/__raw_writel functions which are
implemented on Microblaze and PowerPC.
For ARM readl/writel functions are used instead.
The correct way how to implement this is to detect
endians directly on IP. But for the gpio case
without interrupt connected(it means without
interrupt logic) there are just 2 registers
data and tristate where auto detection can't be done.

Commit 902c098a36 ("random: use lockless techniques in the interrupt
path") turned IRQ path from being spinlock protected into lockless
cmpxchg-retry update.
That commit removed r->lock serialization between crediting entropy bits
from IRQ context and accounting when extracting entropy on userspace
read path, but didn't turn the r->entropy_count reads/updates in
account() to use cmpxchg as well.
It has been observed, that under certain circumstances this leads to
read() on /dev/urandom to return 0 (EOF), as r->entropy_count gets
corrupted and becomes negative, which in turn results in propagating 0
all the way from account() to the actual read() call.
Convert the accounting code to be the proper lockless counterpart of
what has been partially done by 902c098a36.

Commit ec8f02da9e ("random: prime last_data value per fips
requirements") added priming of last_data per fips requirements.
Unfortuantely, it did so in a way that can lead to multiple threads all
incrementing nbytes, but only one actually doing anything with the extra
data, which leads to some fun random corruption and panics.
The fix is to simply do everything needed to prime last_data in a single
shot, so there's no window for multiple cpus to increment nbytes -- in
fact, we won't even increment or decrement nbytes anymore, we'll just
extract the needed EXTRACT_SIZE one time per pool and then carry on with
the normal routine.
All these changes have been tested across multiple hosts and
architectures where panics were previously encoutered. The code changes
are are strictly limited to areas only touched when when booted in fips
mode.
This change should also go into 3.8-stable, to make the myriads of fips
users on 3.8.x happy.

Fix bug in MSI interrupt handling which causes loss of event
notifications.
Typical indication of lost MSI interrupts are stalled message and
doorbell transfers between RapidIO endpoints. To avoid loss of MSI
interrupts all interrupts from the device must be disabled on entering
the interrupt handler routine and re-enabled when exiting it.
Re-enabling device interrupts will trigger new MSI message(s) if Tsi721
registered new events since entering interrupt handler routine.
This patch is applicable to kernel versions starting from v3.2.

A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.
This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.
Examples use-cases include:
* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
devices, and likely many other ARM or embedded systems. These cannot
yet be supported using a full graphics driver, since the panel control
should be provided by the CDF (Common Display Framework), which has been
stuck in design/review for quite some time. One could support these
panels using custom SoC-specific code, but there is a desire to use
common infra-structure rather than having each SoC vendor invent their
own code, hence the desire to wait for CDF.
* Hardware for which a full graphics driver is not yet available, and
the path to obtain one upstream isn't yet clear. For example, the
Raspberry Pi.
* Any hardware in early stages of upstreaming, before a full graphics
driver has been tackled. This driver can provide a graphical boot
console (even full X support) much earlier in the upstreaming process,
thus making new SoC or board support more generally useful earlier.

Add RapidIO enumeration/discovery start from user space. User space

Systems that use RapidIO fabric may need to implement their own
enumeration and discovery methods which are better suitable for needs of
a target application.
The following set of patches is intended to simplify process of
introduction of new RapidIO fabric enumeration/discovery methods.
The first patch offers ability to add new RapidIO enumeration/discovery
methods using kernel configuration options. This new configuration
option mechanism allows to select statically linked or modular
enumeration/discovery method(s) from the list of existing methods or use
external module(s).
This patch also updates the currently existing enumeration/discovery
code to be used as a statically linked or modular method.
The corresponding configuration option is named "Basic
enumeration/discovery" method. This is the only one configuration
option available today but new methods are expected to be introduced
after adoption of provided patches.
The second patch address a long time complaint of RapidIO subsystem
users regarding fabric enumeration/discovery start sequence. Existing
implementation offers only a boot-time enumeration/discovery start which
requires synchronized boot of all endpoints in RapidIO network. While
it works for small closed configurations with limited number of
endpoints, using this approach in systems with large number of endpoints
is quite challenging.
To eliminate requirement for synchronized start the second patch
introduces RapidIO enumeration/discovery start from user space.
For compatibility with the existing RapidIO subsystem implementation,
automatic boot time enumeration/discovery start can be configured in by
specifying "rio-scan.scan=1" command line parameter if statically linked
basic enumeration method is selected.
This patch:
Rework to implement RapidIO enumeration/discovery method selection
combined with ability to use enumeration/discovery as a kernel module.
This patch adds ability to introduce new RapidIO enumeration/discovery
methods using kernel configuration options. Configuration option
mechanism allows to select statically linked or modular
enumeration/discovery method from the list of existing methods or use
external modules. If a modular enumeration/discovery is selected each
RapidIO mport device can have its own method attached to it.
The existing enumeration/discovery code was updated to be used as
statically linked or modular method. This configuration option is named
"Basic enumeration/discovery" method.
Several common routines have been moved from rio-scan.c to make them
available to other enumeration methods and reduce number of exported
symbols.

If the port number is missing from the device-tree the device gets named
xs` instead of xsa. This fixes the check for missing ids.

2) Fix data corruption on some tg3 chips with TSO enabled, from Michael
Chan.
3) Fix double insertion of VLAN tags in be2net driver, from Sarveshwar
Bandi.
4) Don't have TCP's MD5 support pass > PAGE_SIZE page offsets in
scatter-gather entries into the crypto layer, the crypto layer can't

6) Fix OOPS in netfilter log module when called from conntrack, from
Hans Schillstrom.
7) FEC driver needs to use netif_tx_{lock,unlock}_bh() rather than the
non-BH disabling variants. From Fabio Estevam.
8) TCP GSO can generate out-of-order packets, fix from Eric Dumazet.
9) vxlan driver doesn't update 'used' field of fdb entries when it
should, from Sridhar Samudrala.
10) ipv6 should use kzalloc() to allocate inet6 socket cork options,
otherwise we can OOPS in ip6_cork_release(). From Eric Dumazet.
11) Fix races in bonding set mode, from Nikolay Aleksandrov.
12) Fix checksum generation regression added by "r8169: fix 8168evl
frame padding.", from Francois Romieu.
13) ip_gre can look at stale SKB data pointer, fix from Eric Dumazet.
14) Fix checksum handling when GSO is enabled in bnx2x driver with

18) Fix proportional rate reduction handling in tcp_ack(), from Nandita
Dukkipati.
19) IPSEC layer doesn't return an error when a valid state is detected,
causing an OOPS. Fix from Timo Teräs.

Fixes a race on driver init with registering algorithms where the
driver status flag wasn't being set before self testing started.
Added the cra_alignmask field for CBC and ECB modes.
Fixed a bug in GCM where AES block size was being used instead of
authsize.
Removed use of blkcipher_walk routines for scatterlist processing.
Corner cases in the code prevent us from processing an entire
scatterlist at a time and walking the buffers in block sized chunks
turns out to be unecessary anyway.
Fixed off-by-one error in saving off extra data in the sha code.
Fixed accounting error for number of bytes processed in the sha code.

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.
The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.
This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.
