Conflicts: drivers/net/ethernet/freescale/fec_main.c drivers/net/ethernet/renesas/sh_eth.c net/ipv4/gre.c The GRE conflict is between a bug fix (kfree_skb --> kfree_skb_list) and the splitting of the gre.c code into seperate files. The FEC conflict was two sets of changes adding ethtool support code in an "!CONFIG_M5272" CPP protected block. Finally the sh_eth.c conflict was between one commit add bits set in the .eesr_err_check mask whilst another commit removed the .tx_error_check member and assignments. Signed-off-by: David S.

Power management and ACPI updates for 3.11-rc1
- Hotplug changes allowing device hot-removal operations to fail gracefully (instead of crashing the kernel) if they cannot be carried out completely. From Rafael J Wysocki and Toshi Kani. - Freezer update from Colin Cross and Mandeep Singh Baines targeted at making the freezing of tasks a bit less heavy weight operation. - cpufreq resume fix from Srivatsa S Bhat for a regression introduced during the 3.10 cycle causing some cpufreq sysfs attributes to return wrong values to user space after resume. - New freqdomain_cpus sysfs attribute for the acpi-cpufreq driver to provide information previously available via related_cpus from Lan Tianyu. - cpufreq fixes and cleanups from Viresh Kumar, Jacob Shin, Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia, Arnd Bergmann, and Tang Yuantian. - Fix for an ACPICA regression causing suspend/resume issues to appear on some systems introduced during the 3.4 development cycle from Lv Zheng. - ACPICA fixes and cleanups from Bob Moore, Tomasz Nowicki, Lv Zheng, Chao Guan, and Zhang Rui. - New cupidle driver for Xilinx Zynq processors from Michal Simek. - cpuidle fixes and cleanups from Daniel Lezcano. - Changes to make suspend/resume work correctly in Xen guests from Konrad Rzeszutek Wilk. - ACPI device power management fixes and cleanups from Fengguang Wu and Rafael J Wysocki. - ACPI documentation updates from Lv Zheng, Aaron Lu and Hanjun Guo. - Fix for the IA-64 issue that was the reason for reverting commit |

Merge branch 'for-next' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs updates from Steve French: "Various CIFS/SMB2/SMB3 updates for 3.11. Includes bug fixes - SMB3 support should be much more stable with key DFS fix and also signing possible now (although is more work to do to get SMB3 signing working well with multiuser). Mounts using the new SMB 3.02 dialect can now be done (specify "vers=3.02" on mount) against the most current Microsoft systems. Also includes a big cleanup of the cifs/smb2/smb3 authentication code from Jeff which fixes some long standing problems with the way allowed authentication flavors and signing are configured. Some followon patches later in the cycle will clean up allocation of structures for the various security mechanisms depending on what dialect is chosen (reduces memory usage a little) and to add support for the secure negotiate fsctl (for smb3) which prevents downgrade attacks." * 'for-next' of git://git.samba.org/sfrench/cifs-2.6: (39 commits) cifs: fill TRANS2_QUERY_FILE_INFO ByteCount fields cifs: fix SMB2 signing enablement in cifs_enable_signing [CIFS] Fix build warning [CIFS] SMB3 Signing enablement [CIFS] Do not set DFS flag on SMB2 open [CIFS] fix static checker warning cifs: try to handle the MUST SecurityFlags sanely When server doesn't provide SecurityBuffer on SMB2Negotiate pick default Handle big endianness in NTLM (ntlmv2) authentication revalidate directories instiantiated via FIND_* in order to handle DFS referrals SMB2 FSCTL and IOCTL worker function Charge at least one credit, if server says that it supports multicredit Remove typo Some missing share flags cifs: using strlcpy instead of strncpy Update headers to update various SMB3 ioctl definitions Update cifs version number Add ability to dipslay SMB3 share flags and capabilities for debugging Add some missing SMB3 and SMB3.02 flags Add SMB3.02 dialect support ... |

kbuild: create directory for dir/file.o
When add a obj with dir to obj-y, like this
obj-y += dir/file.o
The $(obj)/dir not created, this patch fix this.
When try to add a file(which in a subdir) to my board's obj-y, the build
progress crashed.
For example, I use at91rm9200ek board, and in kernel dir run:
mkdir objtree
make O=objtree at91rm9200_defconfig
mkdir arch/arm/mach-at91/dir
touch arch/arm/mach-at91/dir/file.c
and edit arch/arm/mach-at91/dir/file.c to add some code.
then edit arch/arm/mach-at91/Makefile, change the following line:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o
to:
obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o dir/file.o
Now build it:
make O=objtree
Then the error appears:
...
CC arch/arm/mach-at91/board-rm9200dk.o
CC arch/arm/mach-at91/board-rm9200ek.o
CC arch/arm/mach-at91/dir/file.o
linux-2.6/arch/arm/mach-at91/dir/file.c:5:
fatal error: opening dependency file
arch/arm/mach-at91/dir/.file.o.d: No such file or directory
Check the objtree:
LANG=en ls objtree/arch/arm/mach-at91/dir
ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory
It's apparently that the target dir not created for file.o
Check kbuild source code. It seems that kbuild create dirs for that in
$(obj-dirs). But if the dir need not to create a built-in.o, It should
never in $(obj-dirs).
So I make this patch to make sure It in $(obj-dirs)
this bug caused by commit

KVM fixes for 3.11
On the x86 side, there are some optimizations and documentation updates. The big ARM/KVM change for 3.11, support for AArch64, will come through Catalin Marinas's tree. s390 and PPC have misc cleanups and bugfixes. There is a conflict due to "s390/pgtable: fix ipte notify bit" having entered 3.10 through Martin Schwidefsky's s390 tree.

spi: Updates for v3.11
A fairly quiet release for the SPI subsystem, the standout changes
being:
- Core support for implementing bits per word constraints implemented by
Stephen Warren, factoring some code out of drivers.
- Addition of polling mode support for the s3c64xx driver as some newer
Exynos systems have taken the unusual step of removing interrupt
support.
- Use of the in-IP FIFO and generic dmaengine support for the OMAP2
driver, providing improved performance.
- Conversion of the mpc512x driver to use the core message queue
infrastructure.
The nicest thing being that all the factoring out into common code leads
to a negative diffstat overall.

Pin control changes for the v3.11 kernel cycle:
- A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing and debugfs support into shape. - We also have device tree support with generic naming conventions for the generic pin configuration. - Delete the unused and confusing direct pinconf API. Now state transitions is *the* way to control pins and multiplexing. - New drivers for Rockchip, TZ1090, and TZ1090 PDC. - Two pin control states related to power management are now handled in the device core: "sleep" and "idle", removing a lot of boilerplate code in drivers. We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJR0Z07AAoJEEEQszewGV1zx+oP/j+bh39e1Fc8ySFNvpwLFFRb EbQZx21XsK+d4fUVYQJ1IBh3e5FTqkmvHarbO1aNttqyk7eN5P4EFb3dLExIX+81 6SJYtldH5ZdvLpJNvSXAX6fUjTD1CtBCDs5z5AvDQjqUArQ2tKlzJJgFXW8MSd3B 5hd7XdU5g30GbVzFwrPbVUZwRM12YVs/HACkP6uFqDjB8KX6nXpETlqeeFW+ApvW RPT7iN/CsFls7gl6mHsPvScdfXar0ilZfu0hTf3EmhlVK1/iPOV6aqAF9z4j2Yxf ICL/x3phJ0Q7yNeZslif0KN3iJnrRGbdNvBi6wim35Ds5Uf3lY2SAhSvxNmkjT8n DB9oBTvQzr5OEv8fstWJAT+BWIdZ6Z91IqJ5Gy40A91oVUU9NDDBR3ur2gIneEUz 51kOUhucCzpiht5A/7djAx6MYYOEUwjGNzjOs7tGcxCxz4+Rb2DbAXZ3Cew45ddh 1QsfL3588A0DTp7ccw7f4QwYveX/cquzia/MD8AtdrUSYFEPfkexEo540/VqMl8j aMJ8Uuca9GSnyXDk+ziwkzLg2DjTw+p+6IygNr2GLrXFH2LTAKRpz/SidyLArDsw 0sTFan0sdU3497rHX5Xc8yCyDY4sXCdQm3/er+TE+Z7V2dS99GuEysCAInIdvM1I Wupqaxw4A25YSmbRFVpR =EbAf -----END PGP SIGNATURE----- Merge tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control changes from Linus Walleij: - A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090.

regmap: Updates for v3.11
A small but useful set of regmap updates this time around:
- An abstraction for bitfields within a register map contributed by
Srinivas Kandagatla, allowing drivers to cope more easily when
hardware designers randomly move things about (mainly when talking
to things like system controllers).
- Changes from Lars-Peter Clausen to allow the MMIO regmap to be used from
hard IRQ context.
- Small improvements to the cache infrastructure and performance,
including a default cache sync operation so now all regmaps can sync
easily.
There's also a pinctrl driver making use of the new bitfield API, merged
here for dependency reasons. There will be a simple add/add conflict
with the pinctrl tree as a result.

ARC changes for 3.11
Highlights of changes:
-Continuation of ARC MM changes from 3.10 including
zero page optimization;
Setting pagecache pages dirty by default;
Non executable stack by default;
Reducing dcache flushes for aliasing VIPT config
-Long overdue rework of pt_regs machinery - removing the unused word gutters
and adding ECR register to baseline (helps cleanup lot of low level code)
-Support for ARC gcc 4.8
-Few other preventive fixes, cosmetics, usage of Kconfig helper..
The diffstat is larger than normal primarily because of arcregs.h header split
as well as beautification of macros in entry.h

Pull ARM updates from Russell King:
"This contains the usual updates from other people (listed below) and
the usual random muddle of miscellaneous ARM updates which cover some
low priority bug fixes and performance improvements.
I've started to put the pull request wording into the merge commits,
which are:
- NoMMU stuff:
This includes the following series sent earlier to the list:
- nommu-fixes
- R7 Support
- MPU support
I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.
This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.
- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.
- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.
- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)
This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"

clocksource: arm_global_timer: Add ARM global timer support
This is a simple driver for the global timer module found in the Cortex
A9-MP cores from revision r1p0 onwards. This should be able to perform
the functions of the system timer and the local timer in an SMP system.
The global timer has the following features:
The global timer is a 64-bit incrementing counter with an
auto-incrementing feature. It continues incrementing after sending
interrupts. The global timer is memory mapped in the private memory
region.
The global timer is accessible to all Cortex-A9 processors in the
cluster. Each Cortex-A9 processor has a private 64-bit comparator that
is used to assert a private interrupt when the global timer has reached
the comparator value. All the Cortex-A9 processors in a design use the
banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt
Controller as a Private Peripheral Interrupt. The global timer is
clocked by PERIPHCLK.

posix_timers: fix racy timer delta caching on task exit
When a task exits, we perform a caching of the remaining cputime delta
before expiring of its timers.
This is done from the following places:
* When the task is reaped. We iterate through its list of
posix cpu timers and store the remaining timer delta to
the timer struct instead of the absolute value.
(See posix_cpu_timers_exit() / posix_cpu_timers_exit_group() )
* When we call posix_cpu_timer_get() or posix_cpu_timer_schedule().
If the timer's task is considered dying when watched from these
places, the same conversion from absolute to relative expiry time
is performed. Then the given task's reference is released.
(See clear_dead_task() ).
The relevance of this caching is questionable but this is another
and deeper debate.
The big issue here is that these two sources of caching don't mix
up very well together.
More specifically, the caching can easily be done twice, resulting
in a wrong delta as it gets spuriously substracted a second time by
the elapsed clock. This can happen in the following scenario:
1) The task exits and gets reaped: we call posix_cpu_timers_exit()
and the absolute timer expiry values are converted to a relative
delta.
2) timer_gettime() -> posix_cpu_timer_get() is called and relies on
clear_dead_task() because tsk->exit_state == EXIT_DEAD.
The delta gets substracted again by the elapsed clock and we return
a wrong result.
To fix this, just remove the caching done on task reaping time. It
doesn't bring much value on its own. The caching done from
posix_cpu_timer_get/schedule is enough.
And it would also be hard to get it really right: we could make it put and
clear the target task in the timer struct so that readers know if they are
dealing with a relative cached of absolute value. But it would be racy.
The only safe way to do it would be to lock the itimer->it_lock so that we
know nobody reads the cputime expiry value while we modify it and its
target task reference. Doing so would involve some funny workarounds to
avoid circular lock against the sighand lock. There is just no reason to
maintain this.
The user visible effect of this patch can be observed by running the
following code: it creates a subthread that launches a posix cputimer
which expires after 10 seconds. But then the subthread only busy loops for 2
seconds and exits. The parent reaps the subthread and read the timer value.
Its expected value should the be the initial timer's expiration value
minus the cputime elapsed in the subthread. Roughly 10 - 2 = 8 seconds:
#include <sys/time.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
#include <pthread.h>
static timer_t id;
static struct itimerspec val = { .it_value.tv_sec = 10, }, new;
static void *thread(void *unused)
{
int err;
struct timeval start, end, diff;
timer_create(CLOCK_THREAD_CPUTIME_ID, NULL, &id);
if (err < 0) {
perror("Can't create timer\n");
return NULL;
}
/* Arm 10 sec timer */
err = timer_settime(id, 0, &val, NULL);
if (err < 0) {
perror("Can't set timer\n");
return NULL;
}
/* Exit after 2 seconds of execution */
gettimeofday(&start, NULL);
do {
gettimeofday(&end, NULL);
timersub(&end, &start, &diff);
} while (diff.tv_sec < 2);
return NULL;
}
int main(int argc, char **argv)
{
pthread_t pthread;
int err;
err = pthread_create(&pthread, NULL, thread, NULL);
if (err) {
perror("Can't create thread\n");
return -1;
}
pthread_join(pthread, NULL);
/* Just wait a little bit to make sure the child got reaped */
sleep(1);
err = timer_gettime(id, &new);
if (err)
perror("Can't get timer value\n");
printf("%d %ld\n", new.it_value.tv_sec, new.it_value.tv_nsec);
return 0;
}
Before the patch:
$ ./posix_cpu_timers
6 2278074
After the patch:
$ ./posix_cpu_timers
8 1158766
Before the patch, the elapsed time got two more seconds spuriously accounted.

posix-timers: correctly get dying task time sample in posix_cpu_timer_schedule()
In order to re-arm a timer after it fired, we take a sample of the current
process or thread cputime.
If the task is dying though, we don't arm anything but we cache the
remaining timer expiration delta for further reads.
Something similar is performed in posix_cpu_timer_get() but here we forget
to take the process wide cputime sample before caching it.
As a result we are storing random stack content, leading every further
reads of that timer to return junk values.
Fix this by taking the appropriate sample in the case of process wide
timers.
This probably doesn't matter much in practice because, at this stage, the
thread is the last one in the group and we reached exit_notify(). This
implies that we called exit_itimers() and there should be no more timers
to handle for that task.
So this is likely dead code anyway but let's fix the current logic
and the warning that came along:
kernel/posix-cpu-timers.c: In function 'posix_cpu_timer_schedule':
kernel/posix-cpu-timers.c:1127: warning: 'now' may be used uninitialized in this function
Then we can start to think further about cleaning up that code.

selftests: add basic posix timers selftests
Add some initial basic tests on a few posix timers interface such as setitimer() and timer_settime(). These simply check that expiration happens in a reasonable timeframe after expected elapsed clock time (user time, user + system time, real time, ...). This is helpful for finding basic breakages while hacking on this subsystem.

posix_cpu_timer: consolidate expiry time type
The posix cpu timer expiry time is stored in a union of two types: a 64 bits field if we rely on scheduler precise accounting, or a cputime_t if we rely on jiffies. This results in quite some duplicate code and special cases to handle the two types. Just unify this into a single 64 bits field. cputime_t can always fit into it.
