Merge tag 'omap-for-v3.9/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into late/omap
From Tony Lindgren:
am33xx specific updates for restart and revision detection.
Also get rid of OMAP_32K_TIMER_HZ as that no longer is needed.
* tag 'omap-for-v3.9/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2: AM33XX: id: Add support for AM335x PG2.0
ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZ
ARM: OMAP2+: AM33xx: Add SoC specific restart hook
Commit c1d1cd597f ("ARM: OMAP2+:
omap_device: remove obsolete pm_lats and early_device code") missed a
few omap_device_build() calls that aren't included as part of the default
OMAP2+ Kconfig, omap2plus_defconfig.
Ideally, all devices that are present on the SoC should be created by
default, and only the corresponding device driver should be configured
or deconfigured in Kconfig. This allows drivers to be built as
modules and loaded later, even if they weren't part of the original
kernel build. Unfortunately, we're not quite there yet.
Thanks to Tony Lindgren for reporting this, found during his
randconfig tests.

Merge tag 'omap-devel-a-for-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.9/am33xx
Fixes and IP block support for the TI AM33xx family of SoCs. These
are prerequisites for power management and some PWM driver changes.
Basic test logs are available from:
http://www.pwsan.com/omap/testlogs/am33xx_fixes_a_3.9/20130208084835/
although it must be noted that I am unable to test these patches on
AM33xx due to an unknown problem with v3.8-rc kernels:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg83525.html
Pull ARM fixes from Russell King:
"I was going to hold these off until v3.8 was out, and send them with a
stable tag, but as everyone else is pushing much bigger fixes which
Linus is accepting, let's save people from the hastle of having to
patch v3.8 back into working or use a stable kernel.
Looking at the diffstat, this really is high value for its size; this
is miniscule compared to how the -rc6 to tip diffstat currently looks.
So, four patches in this set:
- Punit Agrawal reports that the kernel no longer boots on MPCore due
to a new assumption made in the GIC code which isn't true of
earlier GIC designs. This is the biggest change in this set.
- Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
the DT-ification of the GIC support without fixing up non-DT

Pull networking fixes from David Miller:
1) Revert iwlwifi reclaimed packet tracking, it causes problems for a
bunch of folks. From Emmanuel Grumbach.
2) Work limiting code in brcmsmac wifi driver can clear tx status
without processing the event. From Arend van Spriel.
3) rtlwifi USB driver processes wrong SKB, fix from Larry Finger.
4) l2tp tunnel delete can race with close, fix from Tom Parkin.
5) pktgen_add_device() failures are not checked at all, fix from Cong
Wang.
6) Fix unintentional removal of carrier off from tun_detach(),
otherwise we confuse userspace, from Michael S. Tsirkin.
7) Don't leak socket reference counts and ubufs in vhost-net driver,
from Jason Wang.
8) vmxnet3 driver gets it's initial carrier state wrong, fix from Neil
Horman.
9) Protect against USB networking devices which spam the host with 0
length frames, from Bjørn Mork.
10) Prevent neighbour overflows in ipv6 for locally destined routes,
from Marcelo Ricardo. This is the best short-term fix for this, a
longer term fix has been implemented in net-next.
11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This
mistake is largely because the ipv6 functions don't even have some
kind of prefix in their names to suggest they are ipv6 specific.
From Tom Parkin.
12) Check SYN packet drops properly in tcp_rcv_fastopen_synack(), from
Yuchung Cheng.
13) Fix races and TX skb freeing bugs in via-rhine's NAPI support, from
Francois Romieu and your's truly.
14) Fix infinite loops and divides by zero in TCP congestion window
handling, from Eric Dumazet, Neal Cardwell, and Ilpo Järvinen.
15) AF_PACKET tx ring handling can leak kernel memory to userspace, fix
from Phil Sutter.
16) Fix error handling in ipv6 GRE tunnel transmit, from Tommi Rantala.
17) Protect XEN netback driver against hostile frontend putting garbage
into the rings, don't leak pages in TX GOP checking, and add proper
resource releasing in error path of xen_netbk_get_requests(). From
Ian Campbell.
18) SCTP authentication keys should be cleared out and released with
kzfree(), from Daniel Borkmann.
19) L2TP is a bit too clever trying to maintain skb->truesize, and ends
up corrupting socket memory accounting to the point where packet
sending is halted indefinitely. Just remove the adjustments
entirely, they aren't really needed. From Eric Dumazet.
20) ATM Iphase driver uses a data type with the same name as the S390
headers, rename to fix the build. From Heiko Carstens.
21) Fix a typo in copying the inner network header offset from one SKB
to another, from Pravin B Shelar.

In sctp_setsockopt_auth_key, we create a temporary copy of the user
passed shared auth key for the endpoint or association and after
internal setup, we free it right away. Since it's sensitive data, we
should zero out the key before returning the memory back to the
allocator. Thus, use kzfree instead of kfree, just as we do in
sctp_auth_key_put().

We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the
iphase atm device driver, which causes the compile error below.
Unfortunately the s390 typedef can't be renamed, since it's a user visible api,
nor can I change the include order in s390 code to avoid the conflict.
So simply rename the iphase typedef to a new name. Fixes this compile error:

dpll_usb needs the clkdm association so the clkdm can be
turned on before a relock. All other dplls for omap4 belong
to the ALWON (always on) domain.
The association was present as part of the older data file
(clock44xx_data.c) but looks like got accidently dropped with
the common clk convertion.
More details of the patch which fixed this up in the older
data file can be dound here..
http://www.spinics.net/lists/linux-omap/msg63076.html
Adding the .clkdm_name as part of the clk_hw_omap struct also

am33xx_cm_wait_module_ready() checks if register offset is NULL.
int am33xx_cm_wait_module_ready(u16 inst, s16 cdoffs, u16 clkctrl_offs)
{
int i = 0;
if (!clkctrl_offs)
return 0;
In case of AM33xx, CLKCTRL register offset for different clock domains
are not uniformly placed. An example of this would be the RTC clock
domain with CLKCTRL offset at 0x00.
In such cases the module ready check is skipped which leads to a data
abort during boot-up when RTC registers is accessed.
Remove this check here to avoid checking module readiness for modules
with clkctrl register offset at 0x00.

The current HWMOD code expects the memory region with
the IP's SYSCONFIG register to be marked with ADDR_TYPE_RT
flag.
CPGMAC0 hwmod entry specifies two memory regions and marks
both with the flag ADDR_TYPE_RT although only the 2nd region
has the SYSCONFIG register. This leads to the HWMOD code
accessing the wrong memory address for idle and standby
operations. Fix this by removing the ADDR_TYPE_RT flag from
the 1st memory region in CPGMAC0 hwmod entry.

We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).
Further investigation reveals that this regression was triggered by
394ef6403a ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.
This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.
GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested. GFP_ATOMIC is not a flag but
a value. The GFP bitmask flags are all prefixed with __GFP_.
The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation. We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register. This means we can't rely on that telling us
which CPU interface we're connected to. We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.
So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

Playing with skb->truesize is tricky, especially when
skb is attached to a socket, as we can fool memory charging.
Just remove this code, its not worth trying to be ultra

Ian Campbell says:
====================
The Xen netback implementation contains a couple of flaws which can
allow a guest to cause a DoS in the backend domain, potentially
affecting other domains in the system.
CVE-2013-0216 is a failure to sanity check the ring producer/consumer
pointers which can allow a guest to cause netback to loop for an
extended period preventing other work from occurring.
CVE-2013-0217 is a memory leak on an error path which is guest
triggerable.
The following series contains the fixes for these issues, as previously
included in Xen Security Advisory 39:

A buggy or malicious frontend should not be able to confuse netback.
If we spot anything which is not as it should be then shutdown the
device and don't try to continue with the ring in a potentially
hostile state. Well behaved and non-hostile frontends will not be
penalised.
As well as making the existing checks for such errors fatal also add a
new check that ensures that there isn't an insane number of requests
on the ring (i.e. more than would fit in the ring). If the ring
contains garbage then previously is was possible to loop over this
insane number, getting an error each time and therefore not generating
any more pending requests and therefore not exiting the loop in
xen_netbk_tx_build_gops for an externded period.
Also turn various netdev_dbg calls which no precipitate a fatal error
into netdev_err, they are rate limited because the device is shutdown
afterwards.
This fixes at least one known DoS/softlockup of the backend domain.
