4297103560 spi: Updates for 3.6
Since Grant is even more specacularly busy than usual for the time being
 I've been collecting SPI patches for him for this release - probably
 things will revert back to Grant before the next release.  There's
 nothing too exciting here, mostly it's simple driver specific stuff:
 
 - Add spi: to the modaliases of SPI devices to provide namespacing.
 - A driver for AD-FMCOMMS1-EBZ.
 - DT binding for Orion.
 - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.
 
 There may be a few more fixes I've missed, people keep sending me new
 things.

b5409430ff ARM: Kirkwood: Fix PHY disable clk problems
Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.

This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.

However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.

Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate.  This is done by
adding a second function that may be used to enable the PHYs.

f479db44d2 ARM: Kirkwood: Ensure runit clock always ticks.
Marvell engineers tell us:

	It seems that many units use the RUNIT clock.
	SPI, UART, NAND, TWSI, ...
	So it's not possible to clock gate it.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

d76ea24ac4 spi/bcm63xx: fix clock configuration selection
We are currently using an inferior or equal operator for comparing
the transfer frequency with the clock frequency table. Because of
this, we always end up selecting 20Mhz as a frequency, due to the
inequality transfer hz <= 20 Mhz being always true. Fix this by
reversing the inequality, which is how the comparison should be done.

24ab327511 spi/omap2: mark omap2_mcspi_master_setup as __devinit
This warning recently appeared with omap2plus_defconfig:

WARNING: drivers/spi/built-in.o(.devinit.text+0x3c4): Section mismatch in reference from the function omap2_mcspi_probe() to the function .init.text:omap2_mcspi_master_setup()
The function __devinit omap2_mcspi_probe() references
a function __init omap2_mcspi_master_setup().
If omap2_mcspi_master_setup is only used by omap2_mcspi_probe then
annotate omap2_mcspi_master_setup with a matching annotation.

The fix is obviously to mark the omap2_mcspi_master_setup function as
__devinit, rather than __init.

 "It's a rather large series, but well discussed, refined and reviewed.

    f55a6faa38: hrtimer: Provide clock_was_set_delayed()
    4873fa070a: timekeeping: Fix leapsecond triggered load spike issue

  are merely preventing the stuff loops forever issues, which people
  have observed.

  But there is no point in delaying the other 4 commits which achieve
  full correctness into 3.6 as they are tagged for stable anyway.  And I
  rather prefer to have the full fixes merged in bulk than a "prevent
  the observable wreckage and deal with the hidden fallout later"

5651721ede x86/vsyscall: allow seccomp filter in vsyscall=emulate
If a seccomp filter program is installed, older static binaries and
distributions with older libc implementations (glibc 2.13 and earlier)
that rely on vsyscall use will be terminated regardless of the filter
program policy when executing time, gettimeofday, or getcpu.  This is
only the case when vsyscall emulation is in use (vsyscall=emulate is the
default).

This patch emulates system call entry inside a vsyscall=emulate by
populating regs->ax and regs->orig_ax with the system call number prior
to calling into seccomp such that all seccomp-dependencies function
normally.  Additionally, system call return behavior is emulated in line
with other vsyscall entrypoints for the trace/trap cases.

[ v2: fixed ip and sp on SECCOMP_RET_TRAP/TRACE (thanks to luto@mit.edu) ]

91f68c89d8 block: fix infinite loop in __getblk_slow
Commit 080399aaaf ("block: don't mark buffers beyond end of disk as
mapped") exposed a bug in __getblk_slow that causes mount to hang as it
loops infinitely waiting for a buffer that lies beyond the end of the
disk to become uptodate.

The problem was initially reported by Torsten Hilbrich here:

    https://lkml.org/lkml/2012/6/18/54

and also reported independently here:

    http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511

and then Richard W.M.  Jones and Marcos Mello noted a few separate
bugzillas also associated with the same issue.  This patch has been
confirmed to fix:

    https://bugzilla.redhat.com/show_bug.cgi?id=835019

The main problem is here, in __getblk_slow:

        for (;;) {
                struct buffer_head * bh;
                int ret;

                bh = __find_get_block(bdev, block, size);
                if (bh)
                        return bh;

                ret = grow_buffers(bdev, block, size);
                if (ret < 0)
                        return NULL;
                if (ret == 0)
                        free_more_memory();
        }

__find_get_block does not find the block, since it will not be marked as
mapped, and so grow_buffers is called to fill in the buffers for the
associated page.  I believe the for (;;) loop is there primarily to
retry in the case of memory pressure keeping grow_buffers from
succeeding.  However, we also continue to loop for other cases, like the
block lying beond the end of the disk.  So, the fix I came up with is to
only loop when grow_buffers fails due to memory allocation issues
(return value of 0).

The attached patch was tested by myself, Torsten, and Rich, and was
found to resolve the problem in call cases.

68e67f40b7 ALSA: snd-usb: move calls to usb_set_interface
The rework of the snd-usb endpoint logic moved the calls to
snd_usb_set_interface() into the snd_usb_endpoint implemenation. This
changed the order in which these calls are issued to the device, and
thereby caused regressions for some webcams.

Fix this by moving the calls back to pcm.c for now to make it work again
and use snd_usb_endpoint_activate() to really tear down all remaining
URBs in the flight, consequently fixing another regression caused by USB
packets on the wire after altsetting 0 has been selected.

I couldn't find the vendor ID in any of the online databases, but this
mat has a Pump It Up logo on the top side of the controller compartment,
and a disclaimer stating that Andamiro will not be liable on the bottom.

The rate of xusbxti clock is set in individual machine files.
The default value should be defined at the clock definition

41002f8dd5 hwmon: (it87) Preserve configuration register bits on init
We were accidentally losing one bit in the configuration register on
device initialization. It was reported to freeze one specific system
right away. Properly preserve all bits we don't explicitly want to
change in order to prevent that.

c4686c71a9 cpufreq / ACPI: Fix not loading acpi-cpufreq driver regression
Commit d640113fe8 introduced a regression on SMP
systems where the processor core with ACPI id zero is disabled
(typically should be the case because of hyperthreading).
The regression got spread through stable kernels.
On 3.0.X it got introduced via 3.0.18.

Such platforms may be rare, but do exist.
Look out for a disabled processor with acpi_id 0 in dmesg:
ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled)

This problem has been observed on a:
HP Proliant BL280c G6 blade

This patch restricts the introduced workaround to platforms
with nr_cpu_ids <= 1.

ebc35c7262 ARM: EXYNOS: register devices in 'need_restore' state for pm_domains
Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to
inactive domains') introduced possibility to add devices to inactive
power domains and added pm_genpd_dev_need_restore() function which lets
platform core to notify power domain core that the specified device must
be restored (with its runtime_resume() callback) before first use.

This patch adds the pm_genpd_dev_need_restore() call what brings back
the suspend/resume behaviour for the client devices known from the
previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM:
EXYNOS: Hook up power domains to generic power domain infrastructure').
Client device drivers relay on that suspend/resume behaviour, thus this
patch fixes runtime pm operation for client devices.

always 'on'.

The macros just called BUG(), but that results in unused variable
warnings all over the place, like in the IPMI driver.  The build
regression emails were annoying me, so here's the fix.  I have
not even compile tested this, but it's rather obvious.
