Use a naming based on vtime as a prefix for virtual based
cputime accounting APIs:
- account_system_vtime() -> vtime_account()
- account_switch_vtime() -> vtime_task_switch()
It makes it easier to allow for further declension such
as vtime_account_system(), vtime_account_idle(), ... if we
want to find out the context we account to from generic code.
This also make it better to know on which subsystem these APIs
refer to.

If __pevent_parse_format() succeeded but add_event() failed, 'ret' didn't
have a proper error code. Set it to PEVENT_ERRNO__MEM_ALLOC_FAILED.
In addition, at that point 'event' also has fields and format
information and they all need to be freed. Call pevent_free_format() to
handle it.

Commit "regulator: deprecate regulator-compatible DT property" deprecated

When the bindings for the TPS6586x regulator were being proposed, I
asserted that DT node naming rules for bus child nodes should also be
applied to nodes inside the TPS6586x regulator node itself. In other
words, that each node providing regulator init data should be named
after the type of object it represented ("regulator") and hence that
some other property was required to indicate which regulator the node
described ("regulator-compatible"). In turn this led to multiple nodes
having the same name, thus requiring node names to use a unit address
to make them unique, thus requiring reg properties within the nodes and
However, subsequent discussion indicates that the rules I was asserting
only applies to standardized bus nodes, and within a device's own node,
the binding can basically do anything sane that it wants.
Hence, this change deprecates the register-compatible property, and
instead uses node names to replace this functionality. This greatly
simplifies the device tree content, making them smaller and more legible.
The code is changed such that old device trees continue to work.

Sandy bridge EDAC is calculating the memory size with overflow.
Basically, the size field and the integer calculation is using 32 bits.
More bits are needed, when the DIMM memories have high density.
The net result is that memories are improperly reported there, when
high-density DIMMs are used:
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 0, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 1, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
As the number of pages value is handled at the EDAC core as unsigned
ints, the driver shows the 16 GB memories at sysfs interface as 16760832
MB! The fix is simple: calculate the number of pages as unsigned 64-bits
integer.
After the patch, the memory size (16 GB) is properly detected:
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 0, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800

adaptive-dynticks changes. Affected architectures are alpha,
cris, frv, h8300, m32r, m68k, mn10300, parisc, score, xtensa,
and ia64.
Some drivers need to switch pin states between GPIO and pin function at
runtime, which was inadvertently broken in the pinctrl driver for GPIOs
being bound to a specific direction.
This fixes up the request path to ensure that previously configured GPIOs
don't cause us to inadvertently error out with an unsupported mux on
reconfig, which in practice is primarily aimed at trapping pull-up/down
users that have yet to be implemented under the new API.
Fixes up regressions in the TPU PWM driver, amongst others.

====================
Please pull this last(?) batch of fixes intended for 3.6...
For the Bluetooth bits, Gustavo says this:
"Here goes probably my last update to 3.6. It includes the two patches
you were ok last week(from Andrzej Kaczmarek), those are critical
ones, and two other fixes one for a system crash and the other for
a missing lockdep annotation."
The referenced fixes from Andrzej prevent attempts to configure devices
that are powered-off.
Along with the Bluetooth fixes, there are a couple of 802.11 fixes.
Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an
interrupt twice. Luis R. Rodriguez provides a fix for a possible
circular lock dependency in the cfg80211 regulatory enforcement code.

Pull a Xen fix from Konrad Rzeszutek Wilk:
"It is a bug-fix when we run the initial PV guest on a AMD K8 machine
and have CONFIG_AMD_NUMA enabled and detect the NUMA topology from the

We end up in the situation where the initial domain gets too much
information and gets confused and crashes - the fix is to restrict the
domain to get the information - and we do it by just disabling NUMA on
the PV guest (the hypervisor is still able to do its proper NUMA
allocations of guests).
It is OK to disable the PV guest from accessing NUMA data as right now
we do not inject any NUMA node information to the PV guests. When we
do get to that point, then this patch will have to be reverted."

The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.

This patch splits trace event initialization in two stages:
* ftrace enable
* sysfs event entry creation
This allows to capture trace events from an earlier point
by using 'trace_event' kernel parameter and is important
to trace boot-up allocations.
Note that, in order to enable events at core_initcall,
it's necessary to move init_ftrace_syscalls() from
core_initcall to early_initcall.

With recent binutils I get:
perf % make
Makefile:668: No bfd.h/libbfd found, install binutils-dev[el]/zlib-static to gain symbol demanglin
That happens because bfd.h now contains:

When process_op failed, @arg will be freed on a caller with type of
PRINT_OP. Thus free_arg() will try to free ->op.right field which can
have stale value if something bad happens in the middle.

perf uses sscanf extension %as to read and allocate a string in the same
step. This is a non-standard extension only present in new versions of
glibc.
Replacing the use of sscanf and %as with strtok_r calls in order to
parse a given string into its components. This is needed in Android
since bionic does not support
%as extension for sscanf.

Because its only user builtin-kvm::get_cpu_isa() has gone, It can be
removed safely. In general, we have the feature information in
perf_session_env already, no need to read it again.
