1ad581ebf3 lustre: get rid of playing with ->fs
* removed several pieces of dead code in lustre_compat25.h
* don't open-code current_umask() (and BTW, 0755 & (S_IRWXUGO | S_ISVTX)
is better spelled as 0755)
* fix broken attempt to get the pathname by dentry - abusing d_path() for
that is simply wrong.

f1f2eac912 nios2/uaccess: fix sparse errors
virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.

427ae153c6 [media] bq/c-qcam, w9966, pms: move to staging in preparation for removal
These drivers haven't been tested in a long, long time. The hardware is
ancient and hopelessly obsolete. These drivers also need to be converted
to newer media frameworks but due to the lack of hardware that's going
to be impossible. In addition, cheaper and vastly better hardware is
available today.

So these drivers are a prime candidate for removal. If someone is
interested in working on these drivers to prevent their removal, then
please contact the linux-media mailinglist.

Let's be honest, the age of parallel port webcams and ISA video capture
boards is really gone.

ea2e813e8c [media] tlg2300: move to staging in preparation for removal
This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.

This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.

In other words, this driver is a prime candidate for removal. If someone is
interested in working on this driver to prevent its removal, then please
contact the linux-media mailinglist.

389208e117 [media] cx88: remove leftover start_video_dma() call
The start_streaming op is responsible for starting the video dma,
so it shouldn't be called anymore from the buf_queue op.

Unfortunately, this call to start_video_dma() was added to the
start_streaming op, but was forgotten to be removed from the
buf_queue op, which is where it used to be before the vb2 conversion.

Calling this function twice causes very hard to find errors: sometimes
it works, sometimes it doesn't. It took me a whole friggin' day
to track this down, and in the end it was just luck that my eye suddenly
triggered on that line.

The cx88 vb2 conversion and the vb2 dma_sg improvements were developed separately and
were merged separately. Unfortunately, the patch updating drivers to the dma_sg
improvements didn't take the updated cx88 driver into account. Basically two ships
passing in the night, unaware of one another even though both ships have the same
owner, i.e. me :-)

6f51ee709e ARM: SoC/iommu configuration for 3.19
The iomm-config branch contains work from Will Deacon, quoting his description:
 
     This series adds automatic IOMMU and DMA-mapping configuration for
     OF-based DMA masters described using the generic IOMMU devicetree
     bindings. Although there is plenty of future work around splitting up
     iommu_ops, adding default IOMMU domains and sorting out automatic IOMMU
     group creation for the platform_bus, this is already useful enough for
     people to port over their IOMMU drivers and start using the new probing
     infrastructure (indeed, Marek has patches queued for the Exynos IOMMU).
 
 The branch touches core ARM and IOMMU driver files, and the respective
 maintainers (Russell King and Joerg Roedel) agreed to have the contents
 merged through the arm-soc tree. The final version was ready just before
 the merge window, so we ended up delaying it a bit longer than the rest,
 but we don't expect to see regressions because this is just additional
 infrastructure that will get used in drivers starting in 3.20 but is
 unused so far.

a7c180aa7e As the merge window is still open, and this code was not as complex
as I thought it might be. I'm pushing this in now.
 
 This will allow Thomas to debug his irq work for 3.20.
 
 This adds two new features:
 
 1) Allow traceopoints to be enabled right after mm_init(). By passing
 in the trace_event= kernel command line parameter, tracepoints can be
 enabled at boot up. For debugging things like the initialization of
 interrupts, it is needed to have tracepoints enabled very early. People
 have asked about this before and this has been on my todo list. As it
 can be helpful for Thomas to debug his upcoming 3.20 IRQ work, I'm
 pushing this now. This way he can add tracepoints into the IRQ set up
 and have users enable them when things go wrong.
 
 2) Have the tracepoints printed via printk() (the console) when they
 are triggered. If the irq code locks up or reboots the box, having the
 tracepoint output go into the kernel ring buffer is useless for
 debugging. But being able to add the tp_printk kernel command line
 option along with the trace_event= option will have these tracepoints
 printed as they occur, and that can be really useful for debugging
 early lock up or reboot problems.
 
 This code is not that intrusive and it passed all my tests. Thomas tried
 them out too and it works for his needs.

There might have a race in napi_schedule(), leaving interrupts disabled forever.
After these patch, the case still work more than 40 hours running.

6a6dc08ff6 xen-netfront: use napi_complete() correctly to prevent Rx stalling
After d75b1ade56 (net: less interrupt
masking in NAPI) the napi instance is removed from the per-cpu list
prior to calling the n->poll(), and is only requeued if all of the
budget was used.  This inadvertently broke netfront because netfront
does not use NAPI correctly.

If netfront had not used all of its budget it would do a final check
for any Rx responses and avoid calling napi_complete() if there were
more responses.  It would still return under budget so it would never
be rescheduled.  The final check would also not re-enable the Rx
interrupt.

Additionally, xenvif_poll() would also call napi_complete() /after/
enabling the interrupt.  This resulted in a race between the
napi_complete() and the napi_schedule() in the interrupt handler.  The
use of local_irq_save/restore() avoided by race iff the handler is
running on the same CPU but not if it was running on a different CPU.

Fix both of these by always calling napi_compete() if the budget was
not all used, and then calling napi_schedule() if the final checks
says there's more work.

6539c44d08 net: Allow FIXED_PHY to be modular.
Otherwise we get things like:

warning: (NET_DSA_BCM_SF2 && BCMGENET && SYSTEMPORT) selects FIXED_PHY which has unmet direct dependencies (NETDEVICES && PHYLIB=y)

In order to make this work we have to rename fixed.c to fixed_phy.c
because the regulator drivers already have a module named "fixed.o".

cb84c2b401 hexagon: Fix build failures in linux-next
hexagon:defconfig fails to build in linux-next since commit 332fd7c4fe
("genirq: Generic chip: Change irq_reg_{readl,writel} arguments").

The primary build failure is

arch/hexagon/include/asm/cacheflush.h: In function 'copy_to_user_page':
arch/hexagon/include/asm/cacheflush.h:89:22: error: 'VM_EXEC' undeclared

This is the result of including of <linux/io.h> from <linux/irq.h>,
which is now necessary due to the use of readl and writel from irq.h.
This causes recursive inclusions in hexagon code; cacheflush.h is included
from mm.h prior to the definition of VM_EXEC.

Fix the problem by moving copy_to_user_page from the hexagon include file to
arch/hexagon/mm/cache.c, similar to other architectures. After this change,
several redefinitions of readl and writel are reported. Those are caused
by recursive inclusions of io.h and asm/cacheflush.h. Fix those problems by
reducing the number of files included from those files. Also, it was necessary
to stop including asm-generic/cacheflush.h from asm/cacheflush.h. Instead,
functionality originally provided by asm-generic/cacheflush.h is now coded
in asm/cacheflush.h directly.

8185e881f9 perf evlist: Do not use hard coded value for a mmap_pages default
So far what is in there by default is what we were using: 512KB + the
control page, but the admin may change that, and if it does to a smaller
value, all calls to tooling for non root users start failing, requiring
that the user manually set --mmap_pages/-m.

Use instead what is in /proc/sys/kernel/perf_event_mlock_kb.
