Linus Torvalds 5167d09ffa arm64 updates for 3.17
Changes include:
  - Context tracking support (NO_HZ_FULL) which narrowly missed 3.16
  - vDSO layout rework following Andy's work on x86
  - TEXT_OFFSET fuzzing for bootloader testing
  - /proc/cpuinfo tidy-up
  - Preliminary work to support 48-bit virtual addresses, but this is
    currently disabled until KVM has been ported to use it (the patches
    do, however, bring some nice clean-up)
  - Boot-time CPU sanity checks (especially useful on heterogenous
    systems)
  - Support for syscall auditing
  - Support for CC_STACKPROTECTOR
  - defconfig updates

Linus Torvalds b8c0aa46b3 This pull request has a lot of work done. The main thing is the changes
to the ftrace function callback infrastructure. It's introducing a
 way to allow different functions to call directly different trampolines
 instead of all calling the same "mcount" one.
 
 The only user of this for now is the function graph tracer, which always
 had a different trampoline, but the function tracer trampoline was called
 and did basically nothing, and then the function graph tracer trampoline
 was called. The difference now, is that the function graph tracer
 trampoline can be called directly if a function is only being traced by
 the function graph trampoline. If function tracing is also happening on
 the same function, the old way is still done.
 
 The accounting for this takes up more memory when function graph tracing
 is activated, as it needs to keep track of which functions it uses.
 I have a new way that wont take as much memory, but it's not ready yet
 for this merge window, and will have to wait for the next one.
 
 Another big change was the removal of the ftrace_start/stop() calls that
 were used by the suspend/resume code that stopped function tracing when
 entering into suspend and resume paths. The stop of ftrace was done
 because there was some function that would crash the system if one called
 smp_processor_id()! The stop/start was a big hammer to solve the issue
 at the time, which was when ftrace was first introduced into Linux.
 Now ftrace has better infrastructure to debug such issues, and I found
 the problem function and labeled it with "notrace" and function tracing
 can now safely be activated all the way down into the guts of suspend
 and resume.
 
 Other changes include clean ups of uprobe code.
 Clean up of the trace_seq() code.
 And other various small fixes and clean ups to ftrace and tracing.

Linus Torvalds e4ca4308c0 The clock framework changes for 3.17 are mostly additions of new clock
drivers and fixes/enhancements to existing clock drivers. There are also
 some non-critical fixes and improvements to the framework core.
 
 Changes to the clock framework core include:
 * improvements to printks on errors
 * flattening the previously hierarchal structure of per-clock entries
   in debugfs
 * allow per-clock debugfs entries that are specific to a particular
   clock driver
 * configure initial clock parent and/or initial clock rate from Device
   Tree
 * several feature enhancements to the composite clock type
 * misc fixes
 
 New clock drivers added include:
 * TI Palmas PMIC
 * Allwinner A23 SoC
 * Qualcomm APQ8084 and IPQ8064 SoCs
 * Rockchip rk3188, rk3066 and rk3288 SoCs
 * STMicroelectronics STiH407 SoC
 * Cirrus Logic CLPS711X SoC
 
 Many fixes, feature enhancements and further clock tree support for
 existing clock drivers also were merged, such as Samsung's "ARMCLK down"
 power saving feature for their Exynos4 & Exynos5 SoCs.

 Out-of-subsystem changes are making the non-atomic iomem 64-bit
 accessors' naming explicit to show both exact order of the 32-bit
 accesses and the non-atomicity of the 64-bit access.
 
 Usage locations are more verbose now as to what access is exactly being
 done vs having a not-very telling "readq" there, for example.
 
 This is needed by E3-12xx hardware where certain mmapped registers
 cannot be accessed with requests crossing a dword boundary.

Anssi Hannula 44fa816bb7 dm cache: fix race affecting dirty block count
nr_dirty is updated without locking, causing it to drift so that it is
non-zero (either a small positive integer, or a very large one when an
underflow occurs) even when there are no actual dirty blocks.  This was
due to a race between the workqueue and map function accessing nr_dirty
in parallel without proper protection.

People were seeing under runs due to a race on increment/decrement of
nr_dirty, see: https://lkml.org/lkml/2014/6/3/648

Fix this by using an atomic_t for nr_dirty.

Greg Thelen d8c712ea47 dm bufio: fully initialize shrinker
1d3d4437ea ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled.  The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags.  So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).

Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.

This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once.  This has been broken since 3.12.

Commit 725c7b570f (ata: libahci_platform: move port_map parameters
into the AHCI structure) moves flags into the struct ahci_host_priv's
.flags field, which causes compiler warnings on 64-bit builds when that
value is cast to a void * pointer. Cast to an unsigned long so that the
subsequent cast to a pointer doesn't produce a warning.

Linus Torvalds 48418bb6e3 SCSI fixes on 20140731
This is a potential data corruption fix: If we get an error sending down a
 barrier, we simply ignore it meaning the barrier semantics get violated
 without anyone being any the wiser.  If the system crashes at this point, the
 filesystem potentially becomes corrupt.  Fix is to report errors on failed
 barriers.

This is a bug fix for the situation when function tsi721_desc_get() fails
to obtain a free transaction descriptor.

The bug usually results in a memory access crash dump when data transfer
scatter-gather list has more entries than size of hardware buffer
descriptors ring.  This fix ensures that error is properly returned to a
caller instead of an invalid entry.

This patch is applicable to kernel versions starting from v3.5.

The current implementation of the libahci does not allow to use multiple
PHYs. This patch adds the support of multiple PHYs by the libahci while
keeping the old bindings valid for device tree compatibility.

This introduce a new way of defining SATA ports in the device tree, with
one port per sub-node. This as the advantage of allowing a per port
configuration. Because some ports may be accessible but disabled in the
device tree, the port_map mask is computed automatically when using
this.

David Vrabel b7dd0e350e x86/xen: safely map and unmap grant frames when in atomic context
arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.

Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.

These two functions are only used in PV guests.

Introduce arch_gnttab_init() to allocates the virtual address space in
advance.

Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call (which ensures
that the required page tables are pre-allocated).

Rafael J. Wysocki b6328a07bd ACPI / PNP: Fix acpi_pnp_match()
The acpi_pnp_match() function is used for finding the ACPI device
object that should be associated with the given PNP device.
Unfortunately, the check used by that function is not strict enough
and may cause success to be returned for a wrong ACPI device object.

To fix that, use the observation that the pointer to the ACPI
device object in question is already stored in the data field
in struct pnp_dev, so acpi_pnp_match() can simply use that
field to do its job.

This problem was uncovered in 3.14 by commit 202317a573 (ACPI / scan:
Add acpi_device objects for all device nodes in the namespace).

has been bound to this PHY yet, so all the checks in phy_init_hw()
against the PHY driver and the PHY driver's config_init function will
return 0. We will therefore never call phy_scan_fixups() as we should.

Fix this by calling phy_scan_fixups() and check for its return value to
restore the intended functionality.

This broke PHY drivers which do register an early PHY fixup callback to
intercept the PHY probing and do things like changing the 32-bits unique
PHY identifier when a pseudo-PHY address has been used, as well as
board-specific PHY fixups that need to be applied during driver probe
time.

Oliver Neukum c472ab68ad cdc-ether: clean packet filter upon probe
There are devices that don't do reset all the way. So the packet filter should
be set to a sane initial value. Failure to do so leads to intermittent failures
of DHCP on some systems under some conditions.
