Allow user-space processes to use transactional execution (TX).
If the TX facility is available user space programs can use
transactions for fine-grained serialization based on the data
objects that are referenced during a transaction. This is
useful for lockless data structures and speculative compiler
optimizations.

Pull more networking fixes from David Miller:
1) Eric Dumazet discovered and fixed what turned out to be a family of
bugs. These functions were using pskb_may_pull() which might need
to reallocate the linear SKB data buffer, but the callers were not
expecting this possibility. The callers have cached pointers to the
packet header areas, and would need to reload them if we were to
continue using pskb_may_pull().
So they could end up reading garbage.
It's easier to just change these RAW4/RAW6/MIP6 routines to use
skb_header_pointer() instead of pskb_may_pull(), which won't modify
the linear SKB data area.
2) Dave Jone's syscall spammer caught a case where a non-TCP socket can
call down into the TCP keepalive code. The case basically involves
creating a raw socket with sk_protocol == IPPROTO_TCP, then calling
setsockopt(sock_fd, SO_KEEPALIVE, ...)
Fixed by Eric Dumazet.
3) Bluetooth devices do not get configured properly while being powered
on, resulting in always using legacy pairing instead of SSP. Fix
from Andrzej Kaczmarek.
4) Bluetooth cancels delayed work erroneously, put stricter checks in
place. From Andrei Emeltchenko.
5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in
cfg80211, from Luis R. Rodriguez.
6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach.
7) Missing module license in bcm87xx driver, from Peter Huewe.
8) Team driver can lose port changed events when adding devices to a
team, fix from Jiri Pirko.
9) Fix endless loop when trying ot unregister PPPOE device in zombie
state, from Xiaodong Xu.
10) batman-adv layer needs to set MAC address of software device
earlier, otherwise we call tt_local_add with it uninitialized.
11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but
that doesn't program the device properly. From Marek Vasut.

Commit 1ad75b9e1628 ("c/r: prctl: add minimal address test to
PR_SET_MM") added some address checking to prctl_set_mm() used by
checkpoint-restore. This causes a build error for no-MMU systems:
kernel/sys.c: In function 'prctl_set_mm':
kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function)
The test for mmap_min_addr doesn't make a lot of sense for no-MMU code
as noted in commit 6e1415467614 ("NOMMU: Optimise away the
{dac_,}mmap_min_addr tests").
This patch defines mmap_min_addr as 0UL in the no-MMU case so that the
compiler will optimize away tests for "addr < mmap_min_addr".

The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.

Pull networking updates from David Miller:
"More bug fixes, nothing gets past these guys"
1) More kernel info leaks found by Mathias Krause, this time in the
IPSEC configuration layers.
2) When IPSEC policies change, we do not properly make sure that cached
routes (which could now be stale) throughout the system will be
revalidated. Fix this by generalizing the generation count
invalidation scheme used by ipv4. From Nicolas Dichtel.
3) When repairing TCP sockets, we need to allow to restore not just the
send window scale, but the receive one too. Extend the existing
interface to achieve this in a backwards compatible way. From
Andrey Vagin.
4) A fix for FCOE scatter gather feature validation erroneously caused
scatter gather to be disabled for things like AOE too. From Ed L
Cashin.
5) Several cases of mishandling of error pointers, from Mathias Krause,
Wei Yongjun, and Devendra Naga.
6) Fix gianfar build, from Richard Cochran.
7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao
Hongjiang.
8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder.
9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde.
10) The removal of the conditional compilation of the clk support code
in the stmmac driver broke things. This is because the interfaces
used are the ones that don't also perform the enable/disable of the
clk. Fix from Stefan Roese.
11) The QFQ packet scheduler can record out of range virtual start
times, resulting later in misbehavior and even crashes. Fix from
Paolo Valente.
12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
receiver when the advertised receive window goes to zero. Detect
this case and force the processing of the IOAT DMA queue when it
happens to avoid getting stuck. Fix from Michal Kubecek.
13) batman-adv assumes that test_bit() returns only 0 or 1, but this is
not true for x86 (which returns -1 or 0, via the 'sbb' instruction).
Fix from Linus Lussing.
14) Fix small packet corruption in e1000, from Tushar Dave.
15) make_blackhole() in the IPSEC policy code can do one read unlock too
many, fix from Li RongQing.
16) The new tcp_try_coalesce() code introduced a bug in TCP URG
handling, fix from Eric Dumazet.
17) Fix memory leak in __netif_receive_skb() when doing zerocopy and
when hit an OOM condition. From Michael S Tsirkin.

The current code fails to ensure that the netlink message actually
contains as many bytes as the header indicates. If a user creates a new
state or updates an existing one but does not supply the bytes for the
whole ESN replay window, the kernel copies random heap bytes into the
replay bitmap, the ones happen to follow the XFRMA_REPLAY_ESN_VAL
netlink attribute. This leads to following issues:
1. The replay window has random bits set confusing the replay handling
code later on.
2. A malicious user could use this flaw to leak up to ~3.5kB of heap
memory when she has access to the XFRM netlink interface (requires
CAP_NET_ADMIN).
Known users of the ESN replay window are strongSwan and Steffen's
iproute2 patch (<http://patchwork.ozlabs.org/patch/85962/>). The latter
uses the interface with a bitmap supplied while the former does not.
strongSwan is therefore prone to run into issue 1.
To fix both issues without breaking existing userland allow using the
XFRMA_REPLAY_ESN_VAL netlink attribute with either an empty bitmap or a
fully specified one. For the former case we initialize the in-kernel
bitmap with zero, for the latter we copy the user supplied bitmap. For
state updates the full bitmap must be supplied.
To prevent overflows in the bitmap length calculation the maximum size
of bmp_len is limited to 128 by this patch -- resulting in a maximum
replay window of 4096 packets. This should be sufficient for all real
life scenarios (RFC 4303 recommends a default replay window size of 64).

After commit b6d86d3d (Fix DIV_ROUND_CLOSEST to support negative dividends),
the following warning is seen if the kernel is compiled with W=1 (-Wextra):
warning: comparison of unsigned expression >= 0 is always true
The warning is due to the test '((typeof(x))-1) >= 0', which is used to detect
if the variable type is unsigned. Research on the web suggests that the warning
disappears if '>' instead of '>=' is used for the comparison.
Tests after changing the macro along that line show that the warning is gone,
and that the result is still correct:
i=-4: DIV_ROUND_CLOSEST(i, 2)=-2
i=-3: DIV_ROUND_CLOSEST(i, 2)=-2
i=-2: DIV_ROUND_CLOSEST(i, 2)=-1
i=-1: DIV_ROUND_CLOSEST(i, 2)=-1
i=0: DIV_ROUND_CLOSEST(i, 2)=0
i=1: DIV_ROUND_CLOSEST(i, 2)=1
i=2: DIV_ROUND_CLOSEST(i, 2)=1
i=3: DIV_ROUND_CLOSEST(i, 2)=2
i=4: DIV_ROUND_CLOSEST(i, 2)=2
Code size is the same as before.

IBM reported a soft lockup after applying the fix for the rename_lock
deadlock. Commit c83ce989cb5f ("VFS: Fix the nfs sillyrename regression
in kernel 2.6.38") was found to be the culprit.
The nfs sillyrename fix used DCACHE_DISCONNECTED to indicate that the
dentry was killed. This flag can be set on non-killed dentries too,
which results in infinite retries when trying to traverse the dentry
tree.
This patch introduces a separate flag: DCACHE_DENTRY_KILLED, which is
only set in d_kill() and makes try_to_ascend() test only this flag.
IBM reported successful test results with this patch.

I found following definition in include/linux/memory.h, in my IA64
platform, SECTION_SIZE_BITS is equal to 32, and MIN_MEMORY_BLOCK_SIZE
will be 0.
#define MIN_MEMORY_BLOCK_SIZE (1 << SECTION_SIZE_BITS)
Because MIN_MEMORY_BLOCK_SIZE is int type and length of 32bits,
so MIN_MEMORY_BLOCK_SIZE(1 << 32) will will equal to 0.
Actually when SECTION_SIZE_BITS >= 31, MIN_MEMORY_BLOCK_SIZE will be wrong.
This will cause wrong system memory infomation in sysfs.
I think it should be:
#define MIN_MEMORY_BLOCK_SIZE (1UL << SECTION_SIZE_BITS)

perturbations"
This reverts commit 970e178985cadbca660feb02f4d2ee3a09f7fdda.
Nikolay Ulyanitsky reported thatthe 3.6-rc5 kernel has a 15-20%
performance drop on PostgreSQL 9.2 on his machine (running "pgbench").
Borislav Petkov was able to reproduce this, and bisected it to this
commit 970e178985ca ("sched: Improve scalability via 'CPU buddies' ...")
apparently because the new single-idle-buddy model simply doesn't find
idle CPU's to reschedule on aggressively enough.
Mike Galbraith suspects that it is likely due to the user-mode spinlocks
in PostgreSQL not reacting well to preemption, but we don't really know
the details - I'll just revert the commit for now.
There are hopefully other approaches to improve scheduler scalability
without it causing these kinds of downsides.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

Move the workqueue cleanup outside the spinlock and use cancel_work_sync,
on closing the channel this seems to be the more correct function.
Remove the never used and constant return value of mISDN_freebchannel.

Current implementation simply ignores attribute flags. Thus, there is
no notification to userland of unsupported features. Check syscall's
attribute flags to let userland know if a feature is supported by the
kernel. This is also needed to distinguish between future kernels what
might support a feature.

- Fix a regression in the readdir cookieverf initialisation
- Fix an RPC over UDP regression
- Ensure that we report all errors in the NFSv4 open code
- Ensure that fsync() reports all relevant synchronisation errors.

On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1
bytes. This is caused by the (wrong) assumption that RFE in the Status Register
is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to
the implementation of synchronized byte ordering, e.g.:
Dummy-TX - RX - Dummy-TX - RX - ...
But since RFE actually stays high after some Dummy-TX, it rather looks like:
Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX)
The last RX byte is clocked in by the bus controller, but ignored by the kernel
when filling the userspace buffer.
This patch fixes the issue by asking for RX via Dummy-TX asynchronously.
Introducing a separate counter for TX bytes.

Commit 43cedbf0e8dfb9c5610eb7985d5f21263e313802 (SUNRPC: Ensure that
we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing
hangs in the case of NFS over UDP mounts.
Since neither the UDP or the RDMA transport mechanism use dynamic slot
allocation, we can skip grabbing the socket lock for those transports.
Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA
case.
Note that the NFSv4.1 back channel assigns the slot directly
through rpc_run_bc_task, so we can ignore that case.

This is a completely different CONFIG_HOTPLUG problem, only
demonstrating another reason why CONFIG_HOTPLUG should go away. I had a
hard time trying to disable it anyway ;-)
The problem this time is lots of code assuming that a call to
add_uevent_var() will guarantee that env->buflen > 0. This is not true
if CONFIG_HOTPLUG is unset. So things like this end up overwriting
env->envp_idx because the array index is -1:
if (add_uevent_var(env, "MODALIAS="))
return -ENOMEM;
len = input_print_modalias(&env->buf[env->buflen - 1],
sizeof(env->buf) - env->buflen,
dev, 0);
Don't know what the best action is, given that there seem to be a *lot*
of this around the kernel. This patch "fixes" the problem for me, but I
don't know if it can be considered an appropriate fix.
[ It is the correct fix for now, for 3.7 forcing CONFIG_HOTPLUG to
always be on is the longterm fix, but it's too late for 3.6 and older
kernels to resolve this that way - gregkh ]

Pass the checks made by decode_getacl back to __nfs4_get_acl_uncached
so that it knows if the acl has been truncated.
The current overflow checking is broken, resulting in Oopses on
user-triggered nfs4_getfacl calls, and is opaque to the point
where several attempts at fixing it have failed.
This patch tries to clean up the code in addition to fixing the
Oopses by ensuring that the overflow checks are performed in
a single place (decode_getacl). If the overflow check failed,
we will still be able to report the acl length, but at least
we will no longer attempt to cache the acl or copy the
truncated contents to user space.

When the NFS_COOKIEVERF helper macro was converted into a static
inline function in commit 99fadcd764 (nfs: convert NFS_*(inode)
helpers to static inline), we broke the initialisation of the
readdir cookies, since that depended on doing a memset with an
argument of 'sizeof(NFS_COOKIEVERF(inode))' which therefore
changed from sizeof(be32 cookieverf[2]) to sizeof(be32 *).
At this point, NFS_COOKIEVERF seems to be more of an obfuscation
than a helper, so the best thing would be to just get rid of it.

For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim. For these specific MoviNAND devices, we skip
these operations.
Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.

Don't mess with file refcounts (or keep a reference to file, for
that matter) in perf_event. Use explicit refcount of its own
instead. Deal with the race between the final reference to event
going away and new children getting created for it by use of
atomic_long_inc_not_zero() in inherit_event(); just have the
latter free what it had allocated and return NULL, that works
out just fine (children of siblings of something doomed are
created as singletons, same as if the child of leader had been
created and immediately killed).

Andreas Bombe reported that the added ktime_t overflow checking added to
timespec_valid in commit 4e8b14526ca7 ("time: Improve sanity checking of
timekeeping inputs") was causing problems with X.org because it caused
timeouts larger then KTIME_T to be invalid.
Previously, these large timeouts would be clamped to KTIME_MAX and would
never expire, which is valid.
This patch splits the ktime_t overflow checking into a new
timespec_valid_strict function, and converts the timekeeping codes
internal checking to use this more strict function.

The new omap4 cpuidle implementation currently requires
ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.
This patch makes it possible to build a non-SMP kernel
for that platform. This is not normally desired for
end-users but can be useful for testing.
Without this patch, building rand-0y2jSKT results in:

drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]
It's not clear if this patch is the best solution for

build the kernel in all configurations, but that does
not mean it will actually work on an OMAP44xx.
