Commit a79ebea62010 (MIPS: ptrace: Fix user pt_regs definition,
use in ptrace_{get, set}regs()) converted struct pt_regs to use __u64.
Some userspace applications (e.g. GDB) include this file directly,
and fail to see this type. Fix by including <linux/types.h>.
The patch fixes the following build failure with GDB 7.8 when using
GLIBC headers created against Linux 3.17:

Currently, we can't call opal wrappers from modules when using the LE
ABIv2, which requires a TOC init. If we do we'll try and load the opal
entry point using the wrong toc and probably explode or worse jump to
the wrong address.
Nothing in upstream is making opal calls from a module, but we do export
one of the wrappers so we should fix this anyway.
This change uses the _GLOBAL_TOC() macro (rather than _GLOBAL) for the
opal wrappers, so that we can do non-local calls to them.

Without the 3.3V regulator node, the SDMMC driver will give these warnings:

Without this patch, the booting the SOCFPGA platform would hang at the
SDMMC driver loading. The issue, debugged by Doug Anderson, turned out
to be that the GPIO bank used by the SD card-detect was not set to

Since the Synopsys GPIO IP can support multiple ports of varying widths, it

amd-xgbe: AMD XGBE driver fixes 2014-10-22

- Perform proper napi packet counting and budget checking

Currently the amd-xgbe driver increments the packets processed counter
each time a descriptor is processed. Since a packet can be represented
by more than one descriptor incrementing the counter in this way is not
appropriate. Also, since multiple descriptors cause the budget check
to be short circuited, sometimes the returned value from the poll
function would be larger than the budget value resulting in a WARN_ONCE
being triggered.
Update the polling logic to properly account for the number of packets
processed and exit when the budget value is reached.

The ndo_set_features callback function was improperly using an unsigned
int to save the current feature value for features such as NETIF_F_RXCSUM.
Since that feature is in the upper 32 bits of a 64 bit variable the
result was always 0 making it not possible to actually turn off the
hardware RX checksum support. Change the unsigned int type to the
netdev_features_t type in order to properly capture the current value
and perform the proper operation.

Since commit 278d24047891 (net: fec: ptp: Enable PPS output based on ptp clock)
fec_enet_interrupt calls fec_ptp_check_pps_event unconditionally, which calls
into ptp_clock_event. If fep->ptp_clock is NULL, ptp_clock_event tries to
dereference the NULL pointer.
Since on i.MX53 fep->bufdesc_ex is not set, fec_ptp_init is never called,
and fep->ptp_clock is NULL, which reliably causes a kernel panic.
This patch adds a check for fep->ptp_clock == NULL in fec_enet_interrupt.

The commit "net: Save TX flow hash in sock and set in skbuf on xmit"
introduced the inet_set_txhash() and ip6_set_txhash() routines to calculate
and record flow hash(sk_txhash) in the socket structure. sk_txhash is used
to set skb->hash which is used to spread flows across multiple TXQs.
But, the above routines are invoked before the source port of the connection
is created. Because of this all outgoing connections that just differ in the
source port get hashed into the same TXQ.
This patch fixes this problem for IPv4/6 by invoking the the above routines
after the source port is available for the socket.

- Division by zero and incorrect programming of the TSC deadline

This fixes boot if the CPU has a TSC deadline timer but a missing or

In commit 8393c524a25609 (MIPS: tlbex: Fix a missing statement for
HUGETLB), the TLB Refill handler was fixed so that non-OCTEON targets
would work properly with huge pages. The change was incorrect in that
it broke the OCTEON case.
The problem is shown here:
xxx0: df7a0000 ld k0,0(k1)
.
.
.
xxxc0: df610000 ld at,0(k1)
xxxc4: 335a0ff0 andi k0,k0,0xff0
xxxc8: e825ffcd bbit1 at,0x5,0x0
xxxcc: 003ad82d daddu k1,at,k0
.
.
.
In the non-octeon case there is a destructive test for the huge PTE
bit, and then at 0, $k0 is reloaded (that is what the 8393c524a25609
patch added).
In the octeon case, we modify k1 in the branch delay slot, but we
never need k0 again, so the new load is not needed, but since k1 is
modified, if we do the load, we load from a garbage location and then
get a nested TLB Refill, which is seen in userspace as either SIGBUS
or SIGSEGV (depending on the garbage).
The real fix is to only do this reloading if it is needed, and never
where it is harmful.

The ->ip_set_list[] array is initialized in ip_set_net_init() and it
has ->ip_set_max elements so this check should be >= instead of >
otherwise we are off by one.

When a port that was used to listen for inbound connections gets closed
and reused for outgoing connections (like rsh ends up doing for stderr
flow), current we may reject the SYN/ACK packet for the new connection
because tcp_conntracks states forbirds a port to become a client while
there is still a TIME_WAIT entry in there for it.
As TCP may expire the TIME_WAIT socket in 60s and conntrack's timeout
for it is 120s, there is a ~60s window that the application can end up
opening a port that conntrack will end up blocking.
This patch fixes this by simply allowing such state transition: if we
see a SYN, in TIME_WAIT state, on REPLY direction, move it to sSS. Note
that the rest of the code already handles this situation, more
specificly in tcp_packet(), first switch clause.

Use strncpy() instead of strcpy(). That's not a security issue, as the
source buffer is taken from DT nodes, but we should still enforce bound
checks. Spotted by Coverity.

It's possible that the call to of_match_device() (introduced in commit
df59fa7f ["spi: orion: support armada extended baud rates"]) may return
a NULL if there is no match in the device tree (or perhaps no device tree
at all). Check the return pointer and set the local device data to the
lowest common denominator orion device data if it is NULL.

For the input PGA to work correctly the ALC clock needs to be active.
Otherwise volume changes are not applied.

PLL_SELFREQDCO bitfield is from bit 3 to 1, but the driver writes bits
from 4 to 1. The bit 4 is 'reserved', so this probably should not cause
any issues, but it's better to fix it.
