Gleb Natapov 8bf00a5299 KVM: VMX: add support for switching of PERF_GLOBAL_CTRL
Some cpus have special support for switching PERF_GLOBAL_CTRL msr.
Add logic to detect if such support exists and works properly and extend
msr switching code to use it if available. Also extend number of generic
msr switching entries to 8.

Christian Borntraeger 52e16b185f KVM: s390: announce SYNC_MMU
KVM on s390 always had a sync mmu. Any mapping change in userspace
mapping was always reflected immediately in the guest mapping.
- In older code the guest mapping was just an offset
- In newer code the last level page table is shared

Christian Borntraeger 1eddb85f88 KVM: s390: Fix tprot locking
There is a potential host deadlock in the tprot intercept handling.
We must not hold the mmap semaphore while resolving the guest
address. If userspace is remapping, then the memory detection in
the guest is broken anyway so we can safely separate the
address translation from walking the vmas.

Cornelia Huck 9e6dabeffd KVM: s390: Fix RUNNING flag misinterpretation
CPUSTAT_RUNNING was implemented signifying that a vcpu is not stopped.
This is not, however, what the architecture says: RUNNING should be
set when the host is acting on the behalf of the guest operating
system.

CPUSTAT_RUNNING has been changed to be set in kvm_arch_vcpu_load()
and to be unset in kvm_arch_vcpu_put().

For signifying stopped state of a vcpu, a host-controlled bit has
been used and is set/unset basically on the reverse as the old
CPUSTAT_RUNNING bit (including pushing it down into stop handling
proper in handle_stop()).

Will Deacon a313f4c55d powerpc/signal32: Fix sigset_t conversion when copying to user
On PPC64, put_sigset_t converts a sigset_t to a compat_sigset_t
before copying it to userspace. There is a typo in the case that
we have 4 words to copy, meaning that we corrupt the compat_sigset_t.

It appears that _NSIG_WORDS can't be greater than 2 at the moment
so this code is probably always optimised away anyway.

Benjamin Herrenschmidt b97021f855 powerpc: Fix atomic_xxx_return barrier semantics
The Documentation/memory-barriers.txt document requires that atomic
operations that return a value act as a memory barrier both before
and after the actual atomic operation.

Our current implementation doesn't guarantee this. More specifically,
while a load following the isync can not be issued before stwcx. has
completed, that completion doesn't architecturally means that the
result of stwcx. is visible to other processors (or any previous stores
for that matter) (typically, the other processors L1 caches can still
hold the old value).

This has caused an actual crash in RCU torture testing on Power 7

This fixes it by changing those atomic ops to use new macros instead
of RELEASE/ACQUIRE barriers, called ATOMIC_ENTRY and ATMOIC_EXIT barriers,
which are then defined respectively to lwsync and sync.

I haven't had a chance to measure the performance impact (or rather
what I measured with kernel compiles is in the noise, I yet have to
find a more precise benchmark)

Kyle Moffett a9a8f77ac7 powerpc: Remove buggy 9-year-old test for binutils < 2.12.1
Recent binutils refuses to assemble AltiVec opcodes when in e500/SPE
mode, as some of those opcodes alias the "SPE" instructions.  This
triggers an ancient binutils version check even when building a kernel
with CONFIG_ALTIVEC disabled.

In theory, the check could be conditionalized on CONFIG_ALTIVEC, but in
practice it has long outlived its utility.  It is virtually impossible
to find binutils older than 2.12.1 (released 2002) in the wild anymore.
Even ancient RedHat Enterprise Linux 4 has binutils-2.14.

To fix the kernel build when done natively on e500 systems with this new
binutils, the test is simply removed.

Kumar Gala 187b9f2aa7 powerpc/book3e-64: Fix debug support for userspace
With the introduction of CONFIG_PPC_ADV_DEBUG_REGS user space debug is
broken on Book-E 64-bit parts that support delayed debug events.  When
switch_booke_debug_regs() sets DBCR0 we'll start getting debug events as
MSR_DE is also set and we aren't able to handle debug events from kernel
space.

We can remove the hack that always enables MSR_DE and loads up DBCR0 and
just utilize switch_booke_debug_regs() to get user space debug working
again.

We still need to handle critical/debug exception stacks & proper
save/restore of state for those exception levles to support debug events
from kernel space like we have on 32-bit.

Salman Qazi 4cecf6d401 sched, x86: Avoid unnecessary overflow in sched_clock
(Added the missing signed-off-by line)

In hundreds of days, the __cycles_2_ns calculation in sched_clock
has an overflow.  cyc * per_cpu(cyc2ns, cpu) exceeds 64 bits, causing
the final value to become zero.  We can solve this without losing
any precision.

We can decompose TSC into quotient and remainder of division by the
scale factor, and then use this to convert TSC into nanoseconds.

GNTTABOP_map_grant_ref hypercall, set the GNTMAP_contains_pte flag and
pass a pointer to the PTE (in init_mm).

After the page is mapped, the usual fault mechanism can be used to
update additional MMs.  This allows the vmalloc_sync_all() to be

Geoff Levand 72f3bea075 powerpc/ps3: Fix lost SMP IPIs
Fixes the PS3 bootup hang introduced in 3.0-rc1 by:

  commit 317f394160
  sched: Move the second half of ttwu() to the remote cpu

Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi()
to ps3_get_irq() for IPI messages.

If lv1_send_event_locally() is called between a previous call to
lv1_send_event_locally() and the coresponding call to
lv1_end_of_interrupt_ext() the second event will not be delivered to the
target cpu.

The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two
IPI messages of the same type are sent to the same target in a relatively
short period of time the second IPI event can become lost when
lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

Anton Blanchard d715e433b7 powerpc: Copy down exception vectors after feature fixups
kdump fails because we try to execute an HV only instruction. Feature
fixups are being applied after we copy the exception vectors down to 0
so they miss out on any updates.

We have always had this issue but it only became critical in v3.0
when we added CFAR support (breaks POWER5) and v3.1 when we added
POWERNV (breaks everyone).

Anton Blanchard 6d1e2c6c1a powerpc: panic if we can't instantiate RTAS
I had to debug a strange situation where all manner of things were
failing. SMT threads, storage and network were all completely broken.

The root cause was we couldn't find enough memory to instantiate RTAS -
this was a network install so the initrd was huge.

Instead of limping along and failing in mysterious ways we should just
panic up front if RTAS exists and we can't allocate space for it.

David S. Miller e88d246871 sparc: Stash orig_i0 into %g6 instead of %g2
As per the comments added by this commit, %g2 turns out to not be a
usable place to save away orig_i0 for syscall restart handling.

In fact all of %g2, %g3, %g4, and %g5 are assumed to be saved across
a system call by various bits of code in glibc.

%g1 can't be used because that holds the syscall number, which would
need to be saved and restored for syscall restart handling too, and
that would only compound our problems :-)

This leaves us with %g6 and %g7 which are for "system use".  %g7 is
used as the "thread register" by glibc, but %g6 is used as a compiler
and assembler temporary scratch register.  And in no instance is %g6
used to hold a value across a system call.

Therefore %g6 is safe for storing away orig_i0, at least for now.

Arnaud Lacombe 63c95fa414 arch/unicore32: do not use EXTRA_AFLAGS or EXTRA_CFLAGS
Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425
    Author: Sam Ravnborg <sam@neptun.(none)>
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

David S. Miller 1d299bc773 sparc: Fix handling of orig_i0 wrt. debugging when restarting syscalls.
Although we provide a proper way for a debugger to control whether
syscall restart occurs, we run into problems because orig_i0 is not
saved and restored properly.

Luckily we can solve this problem without having to make debuggers
aware of the issue.  Across system calls, several registers are
considered volatile and can be safely clobbered.

Therefore we use the pt_regs save area of one of those registers, %g2,
as a place to save and restore orig_i0.

Debuggers transparently will do the right thing because they save and
restore this register already.

Rafael J. Wysocki bc9f54498e PM / shmobile: Avoid restoring the INTCS state during initialization
The SH7372 PM domain initialization routine calls pd_power_up()
that executes the domain's .resume() callback, if present, and for
the A4R domain this callback attepmts to restore the INTCS state from
uninitialized data.  To avoid that, introduce __pd_power_up() that
will only execute the domain's .resume() callback if its second
argument is 'true' and make the SH7372 PM domain initialization
use it with 'false' as its second argument.  Redefine pd_power_up()
as a wrapper around __pd_power_up().

Will Deacon a34dbfb03f ARM: 7160/1: setup: avoid overflowing {elf,arch}_name from proc_info_list
setup_processor copies the arch_name and elf_name fields out of the
selected proc_info_list into two fixed size buffers.

Since the proc_info_list structure is defined in a proc_*.S assembly
file, this can lead to subtle errors if the strings defined there are
too long (for example, corrupting the machine ID).

This patch uses snprintf instead of sprintf to ensure that these buffers
are not overrun.

Feng Tang 57e6319dd6 vrtc: change its year offset from 1960 to 1972
Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.

Updated patch which adds a sanity check suggested by Mathias

This isn't a change in behaviour for systems, because 1972 is the one we
actually use. It's the old version in upstream which is out of sync with
all devices.

e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state

This patch remedies these issues by up-porting the SH-Mobile

It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"

Paul Mundt 750a7eee73 drivers: sh: Generalize runtime PM platform stub.
The runtime PM platform support stub in use by ARM-based SH/R-Mobile
platforms contains nothing that's specifically ARM-related and instead of
wholly generic to anything using the clock framework.

The recent runtime PM changes interact rather badly with the lazy
disabling of clocks late in the boot process through the clock framework,
leading to situations where the runtime suspend/resume paths are entered
without a clock being actively driven due to having been lazily gated
off.

In order to correct this we can trivially tie in the aforementioned stub
as a general fallback for all SH platforms that don't presently have
their own runtime PM implementations (the corner case being SH-based
SH-Mobile platforms, which have their own stub through the hwblk API --
which in turn has bitrotted and will be subsequently adapted to use the
same stub as everyone else), regardless of whether the platforms choose
to define power domains of their own or not.

This fixes up regressions for clock framework users who also build in
runtime PM support without any specific power domains of their own, which
was previously causing the serial console to be lost when warring with
lazy clock disabling.

Maksim Rayskiy 5c20019713 MIPS: ASID conflict after CPU hotplug
I am running SMP Linux 2.6.37-rc1 on BMIPS5000 (single core dual thread)
and observe some abnormalities when doing system suspend/resume which I
narrowed down to cpu hotplugging. The suspend brings the second thread
processor down and then restarts it, after which I see memory corruption
in userspace. I started digging and found out that problem occurs because
while doing execve() the child process is getting the same ASID as the
parent, which obviously corrupts parent's address space.

Further digging showed that activate_mm() calls get_new_mmu_context() to
get a new ASID, but at this time ASID field in entryHi is 1, and
asid_cache(cpu) is 0x100 (it was just reset to ASID_FIRST_VERSION when
the secondary TP was booting).

So, get_new_mmu_context() increments the asid_cache(cpu) value to
0x101, and thus puts 0x01 into entryHi. The result - ASID field does
not get changed as it was supposed to.

My solution is very simple - do not reset asid_cache(cpu) on TP warm
restart.

Mathias Nyman 6fd36ba021 x86, ioapic: Only print ioapic debug information for IRQs belonging to an ioapic chip
with "apic=verbose" the print_IO_APIC() function tries to print
IRQ to pin mappings for every active irq. It assumes chip_data
is of type irq_cfg and may cause an oops if not.

As the print_IO_APIC() is called from a late_initcall other
chained irq chips may already be registered with custom
chip_data information, causing an oops. This is the case with
intel MID SoC devices with gpio demuxers registered as irq_chips.

Jacob Pan 064a59b6dd x86/mrst: Avoid reporting wrong nmi status
Moorestown/Medfield platform does not have port 0x61 to report
NMI status, nor does it have external NMI sources. The only NMI
sources are from lapic, as results of perf counter overflow or
IPI, e.g. NMI watchdog or spin lock debug.

Reading port 0x61 on Moorestown will return 0xff which misled
NMI handlers to false critical errors such memory parity error.
The subsequent ioport access for NMI handling can also cause
undefined behavior on Moorestown.

This patch allows kernel process NMI due to watchdog or backrace
dump without unnecessary hangs.

Stephen Warren 4b91b6fb86 arm/tegra: Don't create duplicate gpio and pinmux devices
*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.

*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.

To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.

Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.

This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:

a) Initializing the HW state from DT nodes during GPIO and pinmux device
   probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
   their probe until after the gpio and pinmux drivers have probed.

v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.

Al Cooper 4f1a1eb530 MIPS: Kernel hangs occasionally during boot.
The Kernel hangs occasionally during boot after "Calibrating delay loop..".
This is caused by the c0_compare_int_usable() routine in cevt-r4k.c
returning false which causes the system to disable the timer and hang later.
The false return happens because the routine is using a series of four calls
to irq_disable_hazard() as a delay while it waits for the timer changes to
propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the
series of irq_disable_hazard() calls turn into ehb instructions and can take
as little as a few clock ticks for all 4 instructions. This is not enough of
a delay, so the routine thinks the timer is not working.  This fix uses up
to a max number of cycle counter ticks for the delay and uses
back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the
hazard condition between cp0 writes and cp0 reads.

Luck, Tony 66f5ddf30a x86/mce: Make mce_chrdev_ops 'static const'
Arjan would like to make struct file_operations const, but
mce-inject directly writes to the mce_chrdev_ops to install its
write handler. In an ideal world mce-inject would have its own
character device, but we have a sizable legacy of test scripts
that hardwire "/dev/mcelog", so it would be painful to switch to
a separate device now. Instead, this patch switches to a stub
function in the mce code, with a registration helper that
mce-inject can call when it is loaded.

Note that this would also allow for a sane process to allow
mce-inject to be unloaded again (with an unregister function,
and appropriate module_{get,put}() calls), but that is left for
potential future patches.

Archit Taneja b923d40dd4 ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in bootloader
Resetting DISPC when a DISPC output is enabled causes the DSS to go into an
inconsistent state. Thus if the bootloader has enabled a display, the hwmod code
cannot reset the DISPC module just like that, but the outputs need to be
disabled first.

Add function dispc_disable_outputs() which disables all active overlay manager
and ensure all frame transfers are completed.

Modify omap_dss_reset() to call this function and clear DSS_CONTROL,
DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the
DSS2 driver starts.

This resolves the hang issue(caused by a L3 error during boot) seen on the
beagle board C3, which has a factory bootloader that enables display. The issue
is resolved with this patch.

Tomi Valkeinen 13662dc5b1 ARM: OMAP: HWMOD: Unify DSS resets for OMAPs
This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.

The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.

This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.

The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.

Tomi Valkeinen 37ad085527 ARM: OMAP4: HWMOD: Add HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core
DSS needs all DSS clocks to be enabled to be able to finish reset
properly. Before v3.1-rc1 the omapdss driver was managing clocks and
resets correctly. However, when omapdss started using runtime PM at
v3.1-rc1, the responsibility for the reset moved to HWMOD framework.

HWMOD framework does not currently enable all the DSS clocks when
resetting the DSS hardware. This causes the HWMOD frameworks boot-time
reset to fail, possibly leaving the DSS hardware in undefined state.

This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag
is actually not used on OMAP4, because dss_core hardware does not have
soft-reset functionality and thus the HWMOD framework never resets nor
waits for the reset to finish.

However, while the flag is not strictly needed currently, I think it
represents the HW correctly: all the DSS clocks should be enabled after
power-on to allow DSS hardware to finish its reset.

A custom reset function will be added in the following patches which
manages this correctly for OMAP4.

properly. Before v3.1-rc1 the omapdss driver was managing clocks and
resets correctly. However, when omapdss started using runtime PM at
v3.1-rc1, the responsibility for the reset moved to HWMOD framework.

HWMOD framework does not currently enable all the DSS clocks when
resetting the DSS hardware. This hasn't caused any problems so far, but
we may just have been lucky.

dss_core's opt-clocks is also missing dss_96m_fck, which is a DSS clock
present only on OMAP3430, and thus required on OMAP3430 to finish the
reset.

This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET and adds the dss_96m_fck
opt-clock for dss_core in OMAP3 HWMOD data, fixing the issue.

Tomi Valkeinen b8ac10d8b7 ARM: OMAP2xxx: HWMOD: fix DSS clock data
The OMAP2xxx HWMOD data currently contains two errors with DSS clocks:

- dss_rfbi is missing ick opt-clock, which is needed for RFBI to
  calculate timings

- dss_venc's interface and main clocks are wrong, causing VENC to fail
  to start

These problems were temporarily fixed with a DSS patch
9ede365aa6 ("HACK: OMAP: DSS2: clk hack
for OMAP2/3"), which can be reverted after this patch (and the similar
patches for other OMAPs).

Russell King abf015f046 Revert "ARM: 7098/1: kdump: copy kernel relocation code at the kexec prepare stage"
This reverts commit 2b034922af.

Will Deacon reports:

This is causing kexec to fail.

The symptoms are that the .init.text section is not loaded as part of the
new kernel image, so when we try to do the SMP/UP fixups we hit a whole sea
of poison left there by the previous kernel.

So my guess is that machine_kexec_prepare *is* too early for preparing the
reboot_code_buffer and, unless anybody has a good reason not to, I'd like to
revert the patch causing these problems.

Deepthi Dharwar 46bcfad7a8 cpuidle: Single/Global registration of idle states
This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.

Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu  would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.

Deepthi Dharwar 4202735e8a cpuidle: Split cpuidle_state structure and move per-cpu statistics fields
This is the first step towards global registration of cpuidle
states. The statistics used primarily by the governor are per-cpu
and have to be split from rest of the fields inside cpuidle_state,
which would be made global i.e. single copy. The driver_data field
is also per-cpu and moved.

Deepthi Dharwar e978aa7d7d cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state
Cpuidle governor only suggests the state to enter using the
governor->select() interface, but allows the low level driver to
override the recommended state. The actual entered state
may be different because of software or hardware demotion. Software
demotion is done by the back-end cpuidle driver and can be accounted
correctly. Current cpuidle code uses last_state field to capture the
actual state entered and based on that updates the statistics for the
state entered.

Ideally the driver enter routine should update the counters,
and it should return the state actually entered rather than the time
spent there. The generic cpuidle code should simply handle where
the counters live in the sysfs namespace, not updating the counters.

Kukjin Kim 830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

The function eseries_register_clks() references
the function __init clkdev_add_table().
This is often because eseries_register_clks lacks a __init
annotation or the annotation of clkdev_add_table is wrong.

by adding the __init annotation to eseries_register_clks() - this
function is only called from other __init-marked functions.  While
we're here, mark it static as it's only called from within eseries.c.

Tomi Valkeinen fc01387302 ARM: OMAP: change get_context_loss_count ret value to int
get_context_loss_count functions return context loss count as u32, and
zero means an error. However, zero is also returned when context has
never been lost and could also be returned when the context loss count
has wrapped and goes to zero.

Change the functions to return an int, with negative value meaning an
error.

OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the
hsmmc code handles the returned value as an int, with negative value
meaning an error, this patch actually fixes hsmmc code also.

This breaks the omap_register_i2c_bus() ABI and results in the igep0020

Peter Ujfalusi 927dbbb22c ARM: OMAP2+: devices: Fixes for McPDM
Commit f718e2c034 (ARM: OMAP2+: devices:
Remove all omap_device_pm_latency structures) removed these structures.
Commit 3528c58eb9 (OMAP: omap_device:
when building return platform_device instead of omap_device) now
returns platform_device instead of omap_device.

Fix up the omap-mcpdm init function since this part comes via sound
tree, and there has been changes regarding to hwmod/omap_device_build.
