Pull OMAP specific fbdev changes from Tomi Valkeinen:
"I've got this pull request separate from the main fbdev pull request,
as this contains a bunch of OMAP board file changes and thus could
possibly be rejected in case of bad conflicts.
The removal of the old display drivers depend on the board file
changes, so Tony Lindgren suggested taking them together via fbdev
tree. These are in linux-next, and also Tony didn't see any conflicts
with any of the branches he had, so they should go in clean.
- Change the OMAP board files to use the new OMAP display drivers
- Remove all the old drivers, and the related auxiliary code"

Merge IPMI fixes from:
"A few things for 3.12 from various people"
* emailed patches from Corey Minyard <minyard@acm.org>:
BMC support for PARISC machines
Add MODULE_ALIAS for autoloading ipmi driver on ACPI systems
ipmi: Initialize locals to avoid warning
ipmi: info leak in compat_ipmi_ioctl()
|
|
The last line of PARISC machines (C8000, RP34x0, etc.) have a BMC for
controlling temperature, fan speed and other stuff. The BMC is
connected via a special bus and listed in the firmware device tree.
This change adds support for these BMCs to the IPMI driver.

I'd submitted this about a year ago but it never made it upstream.

determine the type of BMC device used in the system. The following

Pull Xen updates from Konrad Rzeszutek Wilk:
"A couple of features and a ton of bug-fixes. There is also some
maintership changes. Jeremy is enjoying the full-time work at the
startup and as much as he would love to help - he can't find the time.
I have a bunch of other things that I promised to work on - paravirt
diet, get SWIOTLB working everywhere, etc, but haven't been able to
find the time.
As such both David Vrabel and Boris Ostrovsky have graciously
volunteered to help with the maintership role. They will keep the lid
on regressions, bug-fixes, etc. I will be in the background to help -
but eventually there will be less of me doing the Xen GIT pulls and
more of them. Stefano is still doing the ARM/ARM64 and will continue
on doing so.
Features:
- Xen Trusted Platform Module (TPM) frontend driver - with the
backend in MiniOS.
- Scalability improvements in event channel.
- Two extra Xen co-maintainers (David, Boris) and one going away (Jeremy)
Bug-fixes:
- Make the 1:1 mapping work during early bootup on selective regions.
- Add scratch page to balloon driver to deal with unexpected code
still holding on stale pages.
- Allow NMIs on PV guests (64-bit only)
- Remove unnecessary TLB flush in M2P code.
- Fixes duplicate callbacks in Xen granttable code.
- Fixes in PRIVCMD_MMAPBATCH ioctls to allow retries
- Fix for events being lost due to rescheduling on different VCPUs.
- More documentation"

Pull ext4 updates from Ted Ts'o:
"New features for 3.12:
- Added aggressive extent caching using the extent status tree. This
can actually decrease memory usage in read-mostly workloads since
the information is much more compactly stored in the extent status
tree than if we had to keep the extent tree metadata blocks in the
buffer cache. This also improves Asynchronous I/O since it is it
makes much less likely that we need to do metadata I/O to lookup
the extent tree information.
- Improve the recovery after corrupted allocation bitmaps are found
when running in errors=ignore mode.
Also fixed some writeback vs truncate races when using a blocksize
less than the page size"

Pull pin control changes from Linus Walleij:
"Here is the bulk of pin control changes for the v3.12 series. Most of
the relevant information is in the tag.
I merged in v3.11-rc7 last week to get rid of a largeish conflict
within the sunxi (AllWinner) driver in linux-next and fix up the
non-trivial merge the right way. That driver had a rather large fix
adding locking late in the release cycle.
Overall the bulk changes this time is cleanups and refactorings and
not much new features, which is nice.
- Refactorings for generic pin config handling in the core.
- Factor out a set of device tree utilities for use in all drivers,
to parse and allocate maps from the device tree.
- Some fixes to the core such as more nitpicky locking.
- Pushed down config array iteration into the drivers.
This patch is necessary for drivers that want to iterate over
configs and pile up a stack of alterations to the same register(s),
or if the driver wants to take a local spinlock when committing the
configuration.
- A new driver for the Texas Instruments Palmas PMIC by Laxman
Dewangan. This is used on the Tegra systems.
- A major cleanup and modernization of the PFC (Super Hitachi and ARM
SHmobile) pin controller and subdrivers.
- Support for the A20 and A31 sunxi (AllWinner) SoCs.
- A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

"As a first remark I'd like to point out that the obsolete '-f'
(--force) option, which has not done anything for several releases,
has been removed from 'perf record' and related utilities. Everyone
please update muscle memory accordingly! :-)
Main changes on the perf kernel side:
- Performance optimizations:
. for trace events, by Steve Rostedt.
. for time values, by Peter Zijlstra
- New hardware support:
. for Intel Silvermont (22nm Atom) CPUs, by Zheng Yan
. for Intel SNB-EP uncore PMUs, by Zheng Yan
- Enhanced hardware support:
. for Intel uncore PMUs: add filter support for QPI boxes, by Zheng Yan
- Core perf events code enhancements and fixes:
. for full-nohz feature handling, by Frederic Weisbecker
. for group events, by Jiri Olsa
. for call chains, by Frederic Weisbecker
. for event stream parsing, by Adrian Hunter
- New ABI details:
. Add attr->mmap2 attribute, by Stephane Eranian
. Add PERF_EVENT_IOC_ID ioctl to return event ID, by Jiri Olsa
. Export u64 time_zero on the mmap header page to allow TSC
calculation, by Adrian Hunter

- Code cleanups and refactorings:
. for nohz-full, by Frederic Weisbecker
. for group events, by Jiri Olsa
- Documentation updates:
. for perf_event_type, by Peter Zijlstra
Main changes on the perf tooling side (some of these tooling changes
utilize the above kernel side changes):
- Lots of 'perf trace' enhancements:
. Make 'perf trace' command line arguments consistent with
'perf record', by David Ahern.
. Allow specifying syscalls a la strace, by Arnaldo Carvalho de Melo.
. Add --verbose and -o/--output options, by Arnaldo Carvalho de Melo.
. Support ! in -e expressions, to filter a list of syscalls,
by Arnaldo Carvalho de Melo.
. Arg formatting improvements to allow masking arguments in
syscalls such as futex and open, where the some arguments are
ignored and thus should not be printed depending on other args,
by Arnaldo Carvalho de Melo.
. Beautify futex open, openat, open_by_handle_at, lseek and futex
syscalls, by Arnaldo Carvalho de Melo.
. Add option to analyze events in a file versus live, so that
one can do:
[root@zoo ~]# perf record -a -e raw_syscalls:* sleep 1
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 25.150 MB perf.data (~1098836 samples) ]

far beautifiers for mmap, madvise, syscall return values,
by Arnaldo Carvalho de Melo.
. Handle HUGEPAGE defines in the mmap beautifier, by David Ahern.
- 'perf report/top' enhancements:
. Do annotation using /proc/kcore and /proc/kallsyms when
available, removing the forced need for a vmlinux file kernel
assembly annotation. This also improves this use case because
vmlinux has just the initial kernel image, not what is actually
in use after various code patchings by things like alternatives.
By Adrian Hunter.

of call graphs, by Greg Price.

- 'perf diff' enhancements:
. Add support for more than two files comparison, by Jiri Olsa.
- 'perf sched' enhancements:

PERF_RECORD_{FORK,EXIT} events. By David Ahern.

from a local variable to a global one, by Namhyung Kim.

event, or group of events, be pinned to the PMU.
By Michael Ellerman.
. Support callchain sorting based on addresses, by Andi Kleen

Add support to the core direct-io code to defer AIO completions to user
context using a workqueue. This replaces opencoded and less efficient
code in XFS and ext4 (we save a memory allocation for each direct IO)
and will be needed to properly support O_(D)SYNC for AIO.
The communication between the filesystem and the direct I/O code requires
a new buffer head flag, which is a bit ugly but not avoidable until the
direct I/O code stops abusing the buffer_head structure for communicating
with the filesystems.
Currently this creates a per-superblock unbound workqueue for these
completions, which is taken from an earlier patch by Jan Kara. I'm
not really convinced about this use and would prefer a "normal" global
workqueue with a high concurrency limit, but this needs further discussion.
JK: Fixed ext4 part, dynamic allocation of the workqueue.
