Solve the problems around the broken definition of perf_event_mmap_page::
cap_usr_time and cap_usr_rdpmc fields which used to overlap, partially
fixed by:
860f085b74e9 ("perf: Fix broken union in 'struct perf_event_mmap_page'")
The problem with the fix (merged in v3.12-rc1 and not yet released
officially), noticed by Vince Weaver is that the new behavior is
not detectable by new user-space, and that due to the reuse of the
field names it's easy to mis-compile a binary if old headers are used
on a new kernel or new headers are used on an old kernel.
To solve all that make this change explicit, detectable and self-contained,
by iterating the ABI the following way:
- Always clear bit 0, and rename it to usrpage->cap_bit0, to at least not
confuse old user-space binaries. RDPMC will be marked as unavailable
to old binaries but that's within the ABI, this is a capability bit.
- Rename bit 1 to ->cap_bit0_is_deprecated and always set it to 1, so new
libraries can reliably detect that bit 0 is deprecated and perma-zero
without having to check the kernel version.
- Use bits 2, 3, 4 for the newly defined, correct functionality:
cap_user_rdpmc : 1, /* The RDPMC instruction can be used to read counts */
cap_user_time : 1, /* The time_* fields are used */
cap_user_time_zero : 1, /* The time_zero field is used */
- Rename all the bitfield names in perf_event.h to be different from the
old names, to make sure it's not possible to mis-compile it
accidentally with old assumptions.
The 'size' field can then be used in the future to add new fields and it
will act as a natural ABI version indicator as well.
Also adjust tools/perf/ userspace for the new definitions, noticed by
Adrian Hunter.

There appears to be an error in the second address of the second XOR
engine in the Kirkwood SoC device tree, which is specified as 0xd0b00
but should be 0x60b00.
For confirmation of address see table 581 page 658 of:
http://www.marvell.com/embedded-processors/kirkwood/assets/FS_88F6180_9x_6281_OpenSource.pdf

Pull ARM SoC fixes from Olof Johansson:
"A set of fixes for ARM platforms for 3.12. Among them:
- A fix for build breakage in the MTD subsystem for some PXA devices.
David Woodhouse has this patch in his for-next branch but has not
been responding to our requests to send it up so here it is. I
should have amended the commit message to describe the build
failure for CONFIG_OF=n setups, but forgot and now it's down in the
stack of commits.
- Added device-tree for the BeagleBone Black. Turns out people have
been using the older "regualar" bone DT for the newer boards, and
there's risk of damaging hardware that way.
- Misc DT and regular fixes for OMAP.
- Fix to make the ST-Ericsson "snowball" boards boot with
multi_v7_defconfig, and enable one of the ST-E reference boards on
the same config.
- Kconfig cleanup for u300 to hide submenus when the platform isn't
enabled.
- Enable ARM_ATAG_DTB_COMPAT to let firmware override command line
when booting with an appended devicetree on non-DT-enabled firmware
(needed to boot snowball)"

Pull MIPS updates from Ralf Baechle:
- Minor updates and fixes to the Octeon ethernet driver in staging
- A fix to VGA_MAP_MEM() for 64 bit platforms
- Fix a workaround for 74K/1074K processors
- The symlink arch/mips/boot/dts/include/dt-bindings was pointing to a
a file with a name ending in \n. I think this may have been caused
by a git bug with with patches sent by email
- A build fix for VGA console on BCM1480-based systems
- Fix PCI device access via "/sys/bus/pci/.../resource0" or similar
work for Alchemy platforms
- Fix potential data leak on MIPS R5 cores. This doesn't add proper
support for any R5 features, just ensures a kernel without such
support will be secure to run
- Adding a macros for the CP0 Config5 register to be used by the R5 fix
- Make get_cycles() actually return something useful where possible
This also requires a preparatory patch for performance sake
- Fix a warning about the use of smp_processor_id() in preemptible
code. Again this includes a preparatory patch adding the
infrastructure to be used by the actual patch
- Finally remove pointless one-line comment
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: Fix invalid symbolic link file
MIPS: PCI: pci-bcm1480: Include missing vt.h header
MIPS: Disable usermode switching of the FR bit for MIPS R5 CPUs.
MIPS: Add MIPS R5 config5 register.

Currently the kernel will always use the FR=0 register model for O32. If
an O32 application did enable FR=1 mode, some data from another application
might be leaked in the extra registers becoming visible.
Iow, this patch is meant to make the kernel MIPS R5 tolerant but leaves
proper MIPS R5 support to a future patchset.

Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq:
remove device tree parsing for cpu nodes" assumed the pdev->dev is set to
cpu0 device in the platform code. But it actually points to the virtual
cpufreq-cpu0 platform device which is not present in the device tree.
Most of the information needed by cpufreq is stored in cpu0 DT node.
So cpu_dev must point to cpu0 device.
This patch fixes the wrong assignment to cpu_dev.

With the addition of the Armada XP reference clock, we can now model
accurately the available clock inputs for the timer: namely, nbclk
and refclk. For each of this clock inputs we assign a name, for the
driver to select as appropriate.

The Armada XP SoC has a reference 25 MHz fixed-clock that is used in
some controllers such as the timer and the watchdog. This commit adds
a DT representation of this clock through a fixed-clock compatible node.

Zaurus collie contains 2 LH28F640BFHE-PTTL90 (64M 4Mx16) and

get_cycles to always return 0.]
Most users of get_cycles() invoke it as a timing interface. That's why
in modern kernels it was never very much missed for. /dev/random however
uses get_cycles() in the how the jitter in the interrupt timing contains
some useful entropy.

Add patch to fix 32bit EFI service mapping (rhbz 726701)
Multiple people are reporting hitting the following WARNING on i386,
WARNING: at arch/x86/mm/ioremap.c:102 __ioremap_caller+0x3d3/0x440()

Due to the workaround described in commit 916f676f8 ("x86, efi: Retain
boot service code until after switching to virtual mode") EFI Boot
Service regions are mapped for a period during boot. Unfortunately, with
the limited size of the i386 direct kernel map it's possible that some
of the Boot Service regions will not be directly accessible, which
causes them to be ioremap()'d, triggering the above warning as the
regions are marked as E820_RAM in the e820 memmap.
There are currently only two situations where we need to map EFI Boot
Service regions,
1. To workaround the firmware bug described in 916f676f8
2. To access the ACPI BGRT image
but since we haven't seen an i386 implementation that requires either,
this simple fix should suffice for now.

Commit 76787b3b (ARM: OMAP2+: Remove board-4430sdp.c)
removed legacy booting in favor of device tree based booting
for 4430sdp. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.
I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp,
but the earlier version of this patch was tested by Luciano
Coelho. This version has left out the input logic for MMC CLK
line compared to the earlier version as that is not bidirectional,
and should be safe to do.

Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c)
removed legacy booting in favor of device tree based booting
for pandaboard. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.
The legacy muxing was setting pulls for GPIO 48 and 49, so let's
keep that behaviour for now to avoid further regressions for
BT and FM. Also input logic was enabled for MMC CLK line, but
I've verified that the input logic we don't need enabled for
CLK line as it's not bidirectional.
Also, we want to use non-removable instead of ti,non-removable
as the ti,non-removable also sets no_regulator_off_init which
is really not what we want as then wl12xx won't get powered
up and down which is needed for resetting it.
Note that looks like the WLAN interface fails to come up after
a warm reset, but that most likely was also happening with
the legacy booting and needs a separate fix.

o Move current_cpu_type() to a separate header file
o #ifdefing on supported CPU types lets modern GCC know that certain
code in callers may be discarded ideally turning current_cpu_type() into
a function returning a constant.
o Use current_cpu_type() rather than direct access to struct cpuinfo_mips.
