A very significant modification to NTB in this series.
An abstraction layer was added to allow the hardware and clients to be easily added. This required rewriting the NTB transport layer for this abstraction layer. This modification will allow future "high performance" NTB clients. In addition to this change, a number of performance modifications were added. These changes include NUMA enablement, using CPU memcpy instead of asyncdma, and modification of NTB layer MTU size. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVmCNDAAoJEG5mS6x6i9IjI/QQAINNe7XCENdIL8iQZU2NDWCB BmVhQjKKnS5d774qrCIc/29FoxolTo4MG5H7j1zyGUUrx0mWbjrvRMA4AGt+yE0p Xf4DvFUi+Ptmf/dxlzxwt7ySBAQtAJiPRK0xJjEUqXpJqR/u5eTcsG2og7rXnXE1 DHtgqmh05D4Noi725yyn4qqVrqnUnFtgJ0hp6s7BE5ReeNPJNrD5yRpByEH81TBw +FiUHoCIuhZ4taGbfUU3G6lbBoWqztV8RmjI1AQGRGiij5BmYNZUBTEuSoEt86Df jxoLIz+77A9SGKejSmZbomeeBT3FnlnwHurC8hKdlqF05m3BebiTlCGEmddUdRAa u+8v/z5lmCaxH2Bg0rdQFn1HIvwtnToT4N3nfRtOkywg8tDHfYv2s1IaGO9bosJn XaIS5TR548IgEcsrIjJPX8ab/Q7nBUPkhaIEtXLyPdo41rON7J8aaJnv7bjPq/22 BoHU8fIoiYjIsiDPpsIgRAEXSTz8pr3uHU68NDR8R8pzf9OoysZQV9vy7N04YKTy 3Hr+AtEmiPel9YIx9Z8rgvLoMzP/nyxecJeFqUQpLkVR5YWdI50eg5TO9lBMU6Io hqROco8RUxJDC5J3IE75eWpc2YIxUsNo+5IFsxbNJ78OnY6GiF+pWnKx5rxwxs/G YHILdVMg/OBbVX3+fvJV =CyfQ -----END PGP SIGNATURE----- Merge tag 'ntb-4.2' of git://github.com/jonmason/ntb Pull NTB updates from Jon Mason: "This includes a pretty significant reworking of the NTB core code, but has already produced some significant performance improvements.

Pull virtio/vhost cross endian support from Michael Tsirkin:
"I have just queued some more bugfix patches today but none fix
regressions and none are related to these ones, so it looks like a
good time for a merge for -rc1.
The motivation for this is support for legacy BE guests on the new LE
hosts. There are two redeeming properties that made me merge this:
- It's a trivial amount of code: since we wrap host/guest accesses
anyway, almost all of it is well hidden from drivers.
- Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY,
and when it's clear, there's zero overhead (as some point it was
tested by compiling with and without the patches, got the same
stripped binary).
Maybe we could create a Kconfig symbol to enforce the second point:
prevent people from enabling it eg on x86. I will look into this"

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace updates from Eric Biederman: "Long ago and far away when user namespaces where young it was realized that allowing fresh mounts of proc and sysfs with only user namespace permissions could violate the basic rule that only root gets to decide if proc or sysfs should be mounted at all. Some hacks were put in place to reduce the worst of the damage could be done, and the common sense rule was adopted that fresh mounts of proc and sysfs should allow no more than bind mounts of proc and sysfs. Unfortunately that rule has not been fully enforced. There are two kinds of gaps in that enforcement. Only filesystems mounted on empty directories of proc and sysfs should be ignored but the test for empty directories was insufficient. So in my tree directories on proc, sysctl and sysfs that will always be empty are created specially. Every other technique is imperfect as an ordinary directory can have entries added even after a readdir returns and shows that the directory is empty. Special creation of directories for mount points makes the code in the kernel a smidge clearer about it's purpose. I asked container developers from the various container projects to help test this and no holes were found in the set of mount points on proc and sysfs that are created specially. This set of changes also starts enforcing the mount flags of fresh mounts of proc and sysfs are consistent with the existing mount of proc and sysfs. I expected this to be the boring part of the work but unfortunately unprivileged userspace winds up mounting fresh copies of proc and sysfs with noexec and nosuid clear when root set those flags on the previous mount of proc and sysfs. So for now only the atime, read-only and nodev attributes which userspace happens to keep consistent are enforced. Dealing with the noexec and nosuid attributes remains for another time. This set of changes also addresses an issue with how open file descriptors from /proc/<pid>/ns/* are displayed. Recently readlink of /proc/<pid>/fd has been triggering a WARN_ON that has not been meaningful since it was added (as all of the code in the kernel was converted) and is not now actively wrong. There is also a short list of issues that have not been fixed yet that I will mention briefly. It is possible to rename a directory from below to above a bind mount. At which point any directory pointers below the renamed directory can be walked up to the root directory of the filesystem. With user namespaces enabled a bind mount of the bind mount can be created allowing the user to pick a directory whose children they can rename to outside of the bind mount. This is challenging to fix and doubly so because all obvious solutions must touch code that is in the performance part of pathname resolution. As mentioned above there is also a question of how to ensure that developers by accident or with purpose do not introduce exectuable files on sysfs and proc and in doing so introduce security regressions in the current userspace that will not be immediately obvious and as such are likely to require breaking userspace in painful ways once they are recognized" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: vfs: Remove incorrect debugging WARN in prepend_path mnt: Update fs_fully_visible to test for permanently empty directories sysfs: Create mountpoints with sysfs_create_mount_point sysfs: Add support for permanently empty directories to serve as mount points. kernfs: Add support for always empty directories. proc: Allow creating permanently empty directories that serve as mount points sysctl: Allow creating permanently empty directories that serve as mountpoints. fs: Add helper functions for permanently empty directories. vfs: Ignore unlocked mounts in fs_fully_visible mnt: Modify fs_fully_visible to deal with locked ro nodev and atime mnt: Refactor the logic for mounting sysfs and proc in a user namespace |

Pull ACPICA updates from Rafael Wysocki:
"Additional ACPICA material for v4.2-rc1
This will update the ACPICA code in the kernel to upstream revision
20150619 (a bug-fix release mostly including stable-candidate fixes)
and restore an earlier ACPICA commit that had to be reverted due to a
regression introduced by it (the regression is addressed by
blacklisting the only known system affected by it to date).
The only new feature added by this update is the support for
overriding objects in the ACPI namespace and a new ACPI table that can
be used for that called the Override System Definition Table (OSDT).
That should allow us to "patch" the ACPI namespace built from
incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
during system startup without the need to provide replacements for all
of those tables in the future.
Specifics:
- Fix system resume problems related to 32-bit and 64-bit versions of

irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h
At the moment the IRQCHIP_DECLARE macro is only declared locally in drivers/irqchip/irqchip.h. It prevents from using it directly in arch/* directories whenever irqchip drivers only exist there, which happens in a few cases (e.g. arc, arm, microblaze and mips). This patch makes the macro to be globally defined, i.e. in include/linux/irqchip.h, and thus usable for arch-specific declarations of irqchip drivers. In this way, it is very similar to what clocksource does (ie CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h). For now, this patch only moves the declaration of the macro IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make 'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted irqchip drivers.

An input queue and a processing queue is split out from the monolithic fuse connection, each of those having their own spinlock. The end of the patchset adds the ability to clone a fuse connection. This means, that instead of having to read/write requests/answers on a single fuse device fd, the fuse daemon can have multiple distinct file descriptors open. Each of those can be used to receive requests and send answers, currently the only constraint is that a request must be answered on the same fd as it was read from. This can be extended further to allow binding a device clone to a specific CPU or NUMA node. Based on a patchset by Srinivas Eeda and Ashish Samant.

Pull module_platform_driver replacement from Paul Gortmaker:
"Replace module_platform_driver with builtin_platform driver in non
modules.
We see an increasing number of non-modular drivers using
modular_driver() type register functions. There are several downsides
to letting this continue unchecked:
- The code can appear modular to a reader of the code, and they won't
know if the code really is modular without checking the Makefile
and Kconfig to see if compilation is governed by a bool or
tristate.
- Coders of drivers may be tempted to code up an __exit function that
is never used, just in order to satisfy the required three args of
the modular registration function.
- Non-modular code ends up including the <module.h> which increases
CPP overhead that they don't need.
- It hinders us from performing better separation of the module init
code and the generic init code.
So here we introduce similar macros for builtin drivers. Then we
convert builtin drivers (controlled by a bool Kconfig) by making the
following type of mapping:
module_platform_driver() ---> builtin_platform_driver()
module_platform_driver_probe() ---> builtin_platform_driver_probe().
The set of drivers that are converted here are just the ones that
showed up as relying on an implicit include of <module.h> during a
pending header cleanup. So we convert them here vs adding an include
of <module.h> to non-modular code to avoid compile fails. Additonal
conversions can be done asynchronously at any time.
Once again, an unused module_exit function that is removed here
appears in the diffstat as an outlier wrt all the other changes"

ACPICA: EFI: Add EFI interface definitions to eliminate dependency of GNU EFI
ACPICA commit 5d00e67a74542d030f0a55e7a947a020ef0d9693 This patch copies EFI interface definitions to the ACPICA code base so that the EFI utility support can be ported to other EFI implementation. Known issues: 1. MS Builds of uefi_call_wrapper() The uefi_call_wrapper() in GNU EFI is implemented in a the way to work around the ABI difference between Unix and MS. While I don't have environment to test the MS builds. In order to port the ACPICA utilities to other EFI implementation, all that need to be done is to impelement the 64-bit division support and the program entry point where the efi_main() is invoked. Code to impelement these is platform specific, and ACPICA currently choose to hide such platform specific code within the specific EFI impelementation. Lv Zheng.

Power management and ACPI fixes for v4.2-rc1
- Fix a recently added memory leak in an error path in the ACPI
resources management code (Dan Carpenter).
- Fix a build warning triggered by an ACPI video header function
that should be static inline (Borislav Petkov).
- Change names of helper function converting struct fwnode_handle
pointers to either struct device_node or struct acpi_device
pointers so they don't conflict with local variable names
(Alexander Sverdlin).
- Make the hibernate core re-enable nonboot CPUs on failures to
disable them as expected (Vitaly Kuznetsov).
- Increase the default timeout of the device suspend watchdog to
prevent it from triggering too early on some systems (Takashi Iwai).
- Prevent the cpuidle powernv driver from registering idle
states with CPUIDLE_FLAG_TIMER_STOP set if CONFIG_TICK_ONESHOT
is unset which leads to boot hangs (Preeti U Murthy).

Minor merge needed, due to function move.
Main excitement here is Peter Zijlstra's lockless rbtree optimization to
speed module address lookup. He found some abusers of the module lock
doing that too.
A little bit of parameter work here too; including Dan Streetman's breaking
up the big param mutex so writing a parameter can load another module (yeah,
really). Unfortunately that broke the usual suspects, !CONFIG_MODULES and
!CONFIG_SYSFS, so those fixes were appended too.
Cheers,
Rusty.

Pull module updates from Rusty Russell:
"Main excitement here is Peter Zijlstra's lockless rbtree optimization
to speed module address lookup. He found some abusers of the module
lock doing that too.
A little bit of parameter work here too; including Dan Streetman's
breaking up the big param mutex so writing a parameter can load
another module (yeah, really). Unfortunately that broke the usual
suspects, !CONFIG_MODULES and !CONFIG_SYSFS, so those fixes were
appended too"
* tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (26 commits)
modules: only use mod->param_lock if CONFIG_MODULES
param: fix module param locks when !CONFIG_SYSFS.
rcu: merge fix for Convert ACCESS_ONCE() to READ_ONCE() and WRITE_ONCE()
module: add per-module param_lock
module: make perm const
params: suppress unused variable error, warn once just in case code changes.
modules: clarify CONFIG_MODULE_COMPRESS help, suggest 'N'.
kernel/module.c: avoid ifdefs for sig_enforce declaration
kernel/workqueue.c: remove ifdefs over wq_power_efficient
kernel/params.c: export param_ops_bool_enable_only
kernel/params.c: generalize bool_enable_only
kernel/module.c: use generic module param operaters for sig_enforce
kernel/params: constify struct kernel_param_ops uses
sysfs: tightened sysfs permission checks
module: Rework module_addr_{min,max}
module: Use __module_address() for module_address_lookup()
module: Make the mod_tree stuff conditional on PERF_EVENTS || TRACING
module: Optimize __module_address() using a latched RB-tree
rbtree: Implement generic latch_tree
seqlock: Introduce raw_read_seqcount_latch()

- Support for HS38 cores based on ARCv2 ISA
ARCv2 is the next generation ISA from Synopsys and basis for the
HS3{4,6,8} families of processors which retain the traditional ARC mantra of
low power and configurability and are now more performant and feature rich.
HS38x is a 10 stage pipeline core which supports MMU (with huge pages) and
SMP (upto 4 cores) among other features.

sysfs: Add support for permanently empty directories to serve as mount points.
Add two functions sysfs_create_mount_point and sysfs_remove_mount_point that hang a permanently empty directory off of a kobject or remove a permanently emptpy directory hanging from a kobject. Export these new functions so modular filesystems can use them. Cc: stable@vger.kernel.org Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: "Eric W.
