Pull user namespace changes from Eric Biederman:
"While small this set of changes is very significant with respect to
containers in general and user namespaces in particular. The user
space interface is now complete.
This set of changes adds support for unprivileged users to create user
namespaces and as a user namespace root to create other namespaces.
The tyranny of supporting suid root preventing unprivileged users from
using cool new kernel features is broken.
This set of changes completes the work on setns, adding support for
the pid, user, mount namespaces.
This set of changes includes a bunch of basic pid namespace
cleanups/simplifications. Of particular significance is the rework of
the pid namespace cleanup so it no longer requires sending out
tendrils into all kinds of unexpected cleanup paths for operation. At
least one case of broken error handling is fixed by this cleanup.
The files under /proc/<pid>/ns/ have been converted from regular files
to magic symlinks which prevents incorrect caching by the VFS,
ensuring the files always refer to the namespace the process is
currently using and ensuring that the ptrace_mayaccess permission
checks are always applied.
The files under /proc/<pid>/ns/ have been given stable inode numbers
so it is now possible to see if different processes share the same
namespaces.
Through the David Miller's net tree are changes to relax many of the
permission checks in the networking stack to allowing the user
namespace root to usefully use the networking stack. Similar changes
for the mount namespace and the pid namespace are coming through my
tree.
Two small changes to add user namespace support were commited here adn
in David Miller's -net tree so that I could complete the work on the
/proc/<pid>/ns/ files in this tree.
Work remains to make it safe to build user namespaces and 9p, afs,
ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the
Kconfig guard remains in place preventing that user namespaces from
being built when any of those filesystems are enabled.
Future design work remains to allow root users outside of the initial
user namespace to mount more than just /proc and /sys."

Pull block driver update from Jens Axboe:

there is going to be no more over-the-wall pulls and how the
situation on individual pulls can be improved.
- A few cleanups from Akinobu Mita for drbd and cciss.
- Queue improvement for loop from Lukas. This grew into adding a
generic interface for waiting/checking an even with a specific
lock, allowing this to be pulled out of md and now loop and drbd is
also using it.

- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader

- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ

I did not receive a single bug report after interrupt support was
added for a limited number of chips. So I'd say the code is good and
should be enabled for all supported chips, that is: ICH5 and later.

A few leftover fixes for 3.8:
- VIC support for hdmi infoframes with the associated drm helper, fixes
some black TVs (Paulo Zanoni)
- Modeset state check (and fixup if the BIOS messed with the hw) for
lid-open. modeset-rework fallout. Somehow the original reporter went
awol, so this stalled for way too long until we've found a new
victim^Wreporter with broken BIOS.
- seqno wrap fixes from Mika and Chris.
- Some minor fixes all over from various people.
- Another race fix in the pageflip vs. unpin code from Chris.
- hsw vga resume support and a few more fdi link fixes (only used for vga
on hsw) from Paulo.
- Regression fix for DMAR from Zhenyu Wang - I've scavenged memory from my
DMAR for a while and it broke right away :(
- Regression fix from Takashi Iwai for ivb lvds - some w/a needs to be
(partially) moved back into place. Note that these are regressions in
-next.
- One more fix for ivb 3 pipe support - it now actually seems to work.

also physical pages aren't mapped with the kernel space.
The physical pages are mapped with kernel space though vmap

Pull target updates from Nicholas Bellinger:
"It has been a very busy development cycle this time around in target
land, with the highlights including:
- Kill struct se_subsystem_dev, in favor of direct se_device usage
(hch)
- Simplify reservations code by combining SPC-3 + SCSI-2 support for
virtual backends only (hch)
- Simplify ALUA code for virtual only backends, and remove left over
abstractions (hch)
- Pass sense_reason_t as return value for I/O submission path (hch)
- Refactor MODE_SENSE emulation to allow for easier addition of new
mode pages. (roland)
- Add emulation of MODE_SELECT (roland)
- Fix bug in handling of ExpStatSN wrap-around (steve)
- Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
- Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
- Convert ib_srpt to use modern target_submit_cmd caller + drop
legacy ioctx->kref usage (nab)
- Convert ib_srpt to use modern target_submit_tmr caller (nab)
- Add link_magic for fabric allow_link destination target_items for
symlinks within target_core_fabric_configfs.c code (nab)
- Allocate pointers in instead of full structs for
config_group->default_groups (sebastian)
- Fix 32-bit highmem breakage for FILEIO (sebastian)
All told, hch was able to shave off another ~1K LOC by killing the
se_subsystem_dev abstraction, along with a number of PR + ALUA
simplifications. Also, a nice patch by Roland is the refactoring of
MODE_SENSE handling, along with the addition of initial MODE_SELECT
emulation support for virtual backends.
Sebastian found a long-standing issue wrt to allocation of full
config_group instead of pointers for config_group->default_group[]
setup in a number of areas, which ends up saving memory with big
configurations. He also managed to fix another long-standing BUG wrt
to broken 32-bit highmem support within the FILEIO backend driver.
Thank you again to everyone who contributed this round!"

On a grander scope, it formalizes using the initramfs protocol for

they are fed first in the initramfs blob (lots of bootloaders can
concatenate this at boot time, others can use a single file) in an
uncompressed cpio archive using filenames starting with "kernel/".
The ACPI maintainers requested that this patchset be fed via the x86

This patch adds Image Post Processing(IPP) support for exynos drm driver.
IPP supports image scaler/rotator and input/output DMA operations
using IPP subsystem framework to control FIMC, Rotator and GSC hardware
and supports some user interfaces for user side.
And each IPP-based drivers support Memory to Memory operations
with various converting. And in case of FIMC hardware, it also supports
Writeback and Display output operations through local path.
Features:
- Memory to Memory operation support.
- Various pixel formats support.
- Image scaling support.
- Color Space Conversion support.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
- Writeback operation support to display blended image of FIMD fifo on screen
A summary to IPP Subsystem operations:
First of all, user should get property capabilities from IPP subsystem
and set these properties to hardware registers for desired operations.
The properties could be pixel format, position, rotation degree and
flip operation.
And next, user should set source and destination buffer data using
DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and
destinition buffers.
And next, user can control user-desired hardware with desired operations
such as play, stop, pause and resume controls.
And finally, user can aware of dma operation completion and also get
destination buffer that it contains user-desried result through dequeue
command.
IOCTL commands:
- DRM_EXYNOS_IPP_GET_PROPERTY
. get ipp driver capabilitis and id.
- DRM_EXYNOS_IPP_SET_PROPERTY
. set format, position, rotation, flip to source and destination buffers
- DRM_EXYNOS_IPP_QUEUE_BUF
. enqueue/dequeue buffer and make event list.
- DRM_EXYNOS_IPP_CMD_CTRL
. play/stop/pause/resume control.
Event:
- DRM_EXYNOS_IPP_EVENT
. a event to notify dma operation completion to user side.
Basic control flow:
Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator
or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and
destination buffers -> Command control(Play) -> Event is notified to User
-> User gets destinition buffer complated -> (Enqueue to source and
destination buffers -> Event is notified to User) * N -> Queue/Dequeue to
source and destination buffers -> Command control(Stop) -> Free gem handle
-> Close

A NACK is probably the right thing. I was mostly converting a few
other drivers which used some simple, common patterns to use my new
common code, but this driver was missing it altogether. It looks like
there may be bigger issues, though, as you point out.

As noted earlier, I don't have much interest in this driver. I agree
that there are some other issues with the driver; I think it leaks
memory if it is ever allowed to unload, for one. Feel free to submit
an alternative patch to prevent this driver from being built as a
module.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley:
"This patch set includes two large new drivers: mpt3sas (for the next
gen fusion SAS hardware) and csiostor a FCoE offload driver for the
Chelsio converged network cards (this includes some net changes which
I've OK'd with DaveM).
The rest of the patch is driver updates (qla2xxx, lpfc, hptiop,
be2iscsi) plus a few assorted updates and bug fixes.
We also have a Power Management rework in the Upper Layer Drivers
preparatory to doing ACPI zero power optical devices, but the actual
enabler is still being worked on.

Initiator access config could be easier. The way other storage vendors
have addressed this is to support initiator groups: the admin adds
initiator WWNs to the group, and then LUN permissions can be granted for
the entire group at once.
Instead of changing ktarget's configfs interface, this patch keeps
the configfs interface per-initiator-wwn and just adds a 'tag' field
for each. This should be enough for user tools like targetcli to group
initiator ACLs and sync their configurations.
acl_tag is not used internally, but needs to be kept in configfs so that
all user tools can avoid dependencies on each other.
Code tested to work, although userspace pieces still to be implemented.

"The rest of most-of-MM. The other MM bits await a slab merge.
This patch includes the addition of a huge zero_page. Not a
performance boost but it an save large amounts of physical memory in
some situations.
Also a bunch of Fujitsu engineers are working on memory hotplug.
Which, as it turns out, was badly broken. About half of their patches
are included here; the remainder are 3.8 material."
However, this merge disables CONFIG_MOVABLE_NODE, which was totally
broken. We don't add new features with "default y", nor do we add
Kconfig questions that are incomprehensible to most people without any
help text. Does the feature even make sense without compaction or
memory hotplug?

Pull regulator updates from Mark Brown:
"A fairly quiet release again, a couple of relatively small new
features and a bunch of driver specific work including yet more code
elimination and fixes from Axel Lin.
- Addidion of linear_min_sel for offsetting linear selectors in the
helpers.
- Support for continuous voltage ranges for regulators with extremely
high resolution.
- Drivers for AS3711, DA9055, MAX9873, TPS51632, TPS80031 and ARM

Some initialization errors are reported with the existing OCTEON EDAC
support patch. Also some parts have more than one memory controller.
Fix the errors and add multiple controllers if present.
Signed-off-by: David Daney <david.daney@cavium.com>
The patch needs to eliminate the definition of OCTEON_IRQ_BOOTDMA so
that the device tree code can map the interrupt, so in order to not
temporarily break things, we do a single patch to both the interrupt
registration code and the pata_octeon_cf driver.
Also rolled in is a conversion to use hrtimers and corrections to the
timing calculations.

When fimd resumes, the dma will continue from where it left off
and will throw a PAGE FAULT since the memory was freed.
This patch fixes the above problem by disabling the fimd windows
before disabling the fimd clocks. It also keeps track of which
windows were currently active by setting the 'resume' flag. When
fimd resumes, the window with a resume flag set is enabled again.
Now if a current fb is removed when fimd is off, fimd_win_disable
will set the 'resume' flag of that window to zero and return.
So when fimd resumes, that window will not be resumed.
This patch is based on the following two patches:
http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=341e973c967304976a762211b6465b0074de62efhttp://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=cfa22e49b7408547c73532c4bb03de47cc034a05
These two patches are rebased onto the current kernel with
additional changes like removing 'fimd_win_commit' call from
the resume function since this is taken care by encoder
dpms, and the modification of resume flag in win_disable.

When mixer is turned off, we disable the clocks which will stop
the dma. Now if we remove the current framebuffer, we cannot
disable the overlay but the current framebuffer will still be freed.
When mixer resumes, the dma will continue from where it left off
and will throw a PAGE FAULT since the memory was freed.
This patch fixes the above problem by disabling the mixer windows
before disabling the mixer clocks. It also keeps track of which

It is more optimium to use wait queues while waiting for vsync so
that the current task is put to sleep. This way, the task wont
hog the CPU while waiting. We use wait_event_timeout and not
an interruptible function since we dont want the function to exit
when a signal is pending (e.g. drm release). This patch modifies
the wait for vblank function of fimd.

Instead, when dma_buf_detach is called, that would be done.
And also removes exynos_get_sgt function used to get clone sgt

Commit 0e8276ef75 (OMAPDSS: DPI: always
use DSI PLL if available) made dpi.c use DSI PLL for its clock. This
works fine, for DPI, but has a nasty side effect on OMAP3:
On OMAP3 the same clock is used for DISPC fclk and LCD output. Thus,
after the above patch, DSI PLL is used for DISPC and LCD output. If
TV-out is used, the TV-out needs DISPC. And if DPI is turned off, the
DSI PLL is also turned off, disabling DISPC.
For this to work, we'd need proper DSS internal clock handling, with
refcounts, which is a non-trivial project.
This patch fixes the issue for now by disabling the use of DSI PLL for
DPI on OMAP3.

which is very similar to the body of async_tx_quiesce(),
except that the later handles an error from dma_wait_for_async_tx()
(admittedly by panicing, but that decision belongs in the dma
code, not the md code).
So just us async_tx_quiesce().

If a resync is aborted cleanly, ->curr_resync is a reliable

If there was an error it is less reliable but we always know that

and set recovery_cp accordingly.

md will current only only checkpoint recovery or resync ever 1/16th
of the device size. As devices get larger this can become a long time
an so a lot of work that might need to be duplicated after a shutdown.
So add a time-based checkpoint. Every 5 minutes limits the amount of
duplicated effort to at most 5 minutes, and has almost zero impact on
performance.

The lockdep warning below is in theory correct but it will be in really weird
rare situation that ends up that deadlock since the tcm fc session is hashed
based the rport id. Nonetheless, the complaining below is about rcu callback
that does the transport_deregister_session() is happening in softirq, where
transport_register_session() that happens earlier is not. This triggers the
lockdep warning below. So, just fix this to make lockdep happy by disabling
the soft irq before calling transport_register_session() in ft_prli.
BTW, this was found in FCoE VN2VN over two VMs, couple of create and destroy
would get this triggered.
v1: was enforcing register to be in softirq context which was not righ. See,
http://www.spinics.net/lists/target-devel/msg03614.html
v2: following comments from Roland&Nick (thanks), it seems we don't have to
do transport_deregister_session() in rcu callback, so move it into ft_sess_free()
but still do kfree() of the corresponding ft_sess struct in rcu callback to
make sure the ft_sess is not freed till the rcu callback.

We need a node which only contains movable memory. This feature is very
important for node hotplug. If a node has normal/highmem, the memory may
be used by the kernel and can't be offlined. If the node only contains
movable memory, we can offline the memory and the node.
All are prepared, we can actually introduce N_MEMORY.
