fa676ca394 sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.c
Move the CPG helpers to drivers/sh/clk-cpg.c V2.

This to allow SH-Mobile ARM to share the code with
SH. All functions except the legacy CPG stuff is moved.

8b5ee113e1 sh: move sh clock.c contents to drivers/sh/clk.
This patch is V2 of the SH clock framework move from
arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All
code except the following functions are moved:
clk_init(), clk_get() and clk_put().

The init function is still kept in clock.c since it
depends on the SH-specific machvec implementation.

The symbols clk_get() and clk_put() already exist in
the common ARM clkdev code, those symbols are left in
the SH tree to avoid duplicating them for SH-Mobile ARM.

538722ca3b microblaze: fix get_user/put_user side-effects
The Microblaze implementations of get_user() and (MMU) put_user() evaluate
the address argument more than once. This causes unexpected side-effects for
invocations that include increment operators, i.e. get_user(foo, bar++).

This patch also removes the distinction between MMU and noMMU put_user().

f8c5fae166 KVM: VMX: blocked-by-sti must not defer NMI injections
As the processor may not consider GUEST_INTR_STATE_STI as a reason for
blocking NMI, it could return immediately with EXIT_REASON_NMI_WINDOW
when we asked for it. But as we consider this state as NMI-blocking, we
can run into an endless loop.

Resolve this by allowing NMI injection if just GUEST_INTR_STATE_STI is
active (originally suggested by Gleb). Intel confirmed that this is
safe, the processor will never complain about NMI injection in this
state.

1. Adds the 'clk_hclk' clock which is of type 'struct clksrc_clk'.
2. Removes all references to the clk_h clock.
3. Addes clk_hclk into the list of sysclks.
4. The clock rate 'hclk' is modified to be derived from clk_hclk.

9c72d016e2 ARM: S5P6440: Remove usage of clk_arm and add clk_armclk clock
The clk_arm clock is of type 'struct clk' whereas on S5P6440,
the arm clock is more suitable to be of type 'struct clksrc_clk'
(since arm clock is divided version of apll clock).

This patch modifies the following.

1. Removes the usage of clk_arm clock (defined in plat-s5p) and
   defines the new clock 'clk_armclk' of type 'struct clksrc_clk'.

2. Rearranges the assignment of clock rate for the fout_a/m/epll
   clocks. This will help in calculating the clock rate of fclk
   from clk_armclk clock and setup the clock rate for fout_m/epll
   for subsequent patches which depend on it.

3. Modifies the clock rate calculation of fclk to be based on
   the newly added clk_armclk clock.

30d5834960 ARM: S5P6440: Change dout_mpll clock type to clksrc_clk clock type.
This patch modifies the following.

1. Modifies the dout_mpll clock type as clksrc_clk clock type.
   This modification allows the use of common clock code in
   managing the dout_mpll clock (which otherwise would need
   custom defined functions such as s5p6440_clk_doutmpll_get_rate).

2. s5p6440_clk_doutmpll_get_rate function is removed as it is
   no longer needed.

fb04911465 ARM: S5P6440: Register apll/mpll/epll mout clocks.
This patch modifies the following.

1. Registers the mout_apll clksrc_clk clock.

2. The mout_mpll and mout_epll were registered as 'struct clk'
   types and then their parents were setup using the s3c_set_clksrc
   function. This patch reduces the two steps into one by registering
   the mout_mpll and mout_epll clocks using the s3c_register_clksrc
   function.

3. As per point 2 above, the init_parents array is no longer required.
   So the mout clocks are now put together in a new array named 'sysclks'.
   The sysclks array will list the system level clocks and more
   clocks will be added to it in the subsequent patches.

bf83de4037 arm: msm: smd: use either package v3 or v4 not both
This modifies SMD to use either the package v3 or package v4,
but not both. The current code tries to allocate as v4 on all
system which can produce a scary looking error message on boot up,

smem_find(16, 40): wrong size 16424
smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL'

With this error the code then falls back on the package v3 allocation
method. This method is inefficient because it causes a slow down
on some systems even when the allocation method can be determined
at compile time. It also causes a kernel size increase that effects
all system and is not needed.

This change corrects the allocation to use one method or the other
and not both.

0fe1ac48be powerpc/perf_event: Fix oops due to perf_event_do_pending call
Anton Blanchard found that large POWER systems would occasionally
crash in the exception exit path when profiling with perf_events.
The symptom was that an interrupt would occur late in the exit path
when the MSR[RI] (recoverable interrupt) bit was clear.  Interrupts
should be hard-disabled at this point but they were enabled.  Because
the interrupt was not recoverable the system panicked.

The reason is that the exception exit path was calling
perf_event_do_pending after hard-disabling interrupts, and
perf_event_do_pending will re-enable interrupts.

The simplest and cleanest fix for this is to use the same mechanism
that 32-bit powerpc does, namely to cause a self-IPI by setting the
decrementer to 1.  This means we can remove the tests in the exception
exit path and raw_local_irq_restore.

This also makes sure that the call to perf_event_do_pending from
timer_interrupt() happens within irq_enter/irq_exit.  (Note that
calling perf_event_do_pending from timer_interrupt does not mean that
there is a possible 1/HZ latency; setting the decrementer to 1 ensures
that the timer interrupt will happen immediately, i.e. within one
timebase tick, which is a few nanoseconds or 10s of nanoseconds.)

use_xsave() is now just a special case of static_cpu_has(), so use
static_cpu_has().

a3c8acd043 x86: Add new static_cpu_has() function using alternatives
For CPU-feature-specific code that touches performance-critical paths,
introduce a static patching version of [boot_]cpu_has().  This is run
at alternatives time and is therefore not appropriate for most
initialization code, but on the other hand initialization code is
generally not performance critical.

On gcc 4.5+ this uses the new "asm goto" feature.

f97cab28b1 [ARM] pxa: make it clear by converting MMC 'delay_detect' to millisecond
delay_detect in HZ is confusing, convert it to be millisecond based. And
thus remove those unnecessary call to msecs_to_jiffies() at runtime for
this field. Other constants are converted assuming HZ == 100, which are
basically true for those platforms.

The assignment in csb726.c was incorrect, and is fixed in this patch as
a result.

The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result

used as a default initialization value, it's acceptable.

829e924585 kprobes/x86: Fix removed int3 checking order
Fix kprobe/x86 to check removed int3 when failing to get kprobe
from hlist. Since we have a time window between checking int3
exists on probed address and getting kprobe on that address,
we can have following scenario:

 -------
 CPU1                     CPU2
 hit int3
 check int3 exists
                          remove int3
                          remove kprobe from hlist
 get kprobe from hlist
 no kprobe->OOPS!
 -------

This patch moves int3 checking if there is no kprobe on that
address for fixing this problem as follows:

 ------
 CPU1                     CPU2
 hit int3
                          remove int3
                          remove kprobe from hlist
 get kprobe from hlist
 no kprobe->check int3 exists
          ->rollback&retry
 ------

21823259a7 sh: Ensure active regions have a backing PMB entry.
In the NUMA or memory hot-add case where system memory has been
partitioned up, we immediately run in to a situation where the existing
PMB entry doesn't cover the new range (primarily as a result of the entry
size being shrunk to match the node size early in the initialization). In
order to fix this up it's necessary to preload a PMB mapping for the new
range prior to activation in order to circumvent reset by MMU.

The minimum section size for the PMB is 16M, so just always error

unconditionally call in to pmb_bolt_mapping() with variable sizes
without wasting a TLB and cache flush for the range.

4bc277ac9c sh: bootmem refactoring.
This reworks much of the bootmem setup and initialization code allowing
us to get rid of duplicate work between the NUMA and non-NUMA cases. The
end result is that we end up with a much more flexible interface for
supporting more complex topologies (fake NUMA, highmem, etc, etc.) which
is entirely LMB backed. This is an incremental step for more NUMA work as
well as gradually enabling migration off of bootmem entirely.

Currently all fpu state access is through tsk->thread.xstate.  Since we wish
to generalize fpu access to non-task contexts, wrap the state in a new
'struct fpu' and convert existing access to use an fpu API.

Signal frame handlers are not converted to the API since they will remain
task context only things.

c9ad488289 x86: Eliminate TS_XSAVE
The fpu code currently uses current->thread_info->status & TS_XSAVE as
a way to distinguish between XSAVE capable processors and older processors.
The decision is not really task specific; instead we use the task status to
avoid a global memory reference - the value should be the same across all
threads.

Eliminate this tie-in into the task structure by using an alternative
instruction keyed off the XSAVE cpu feature; this results in shorter and
faster code, without introducing a global memory reference.

[ hpa: in the future, this probably should use an asm jmp ]

This reworks the memory limit handling to tie in through the available

While we're at it, the crash kernel reservation semantics are reworked
so that we allocate from the bottom up and reduce the risk of having
to disable the memory limit due to a clash with the crash kernel
reservation.

Due to the fact that p4 counters are shared between HT threads
we synthetically divide the whole set of counters into two
non-intersected subsets. And while we're "borrowing" counters
from these subsets we should not be preempted (well, strictly
speaking in p4_hw_config we just pre-set reference to the
subset which allow to save some cycles in schedule routine
if it happens on the same cpu). So use get_cpu/put_cpu pair.

Also p4_pmu_schedule_events should use smp_processor_id rather
than raw_ version. This allow us to catch up preemption issue
(if there will ever be).

e08cae4181 x86: Clean up the hypervisor layer
Clean up the hypervisor layer and the hypervisor drivers, using an ops
structure instead of an enumeration with if statements.

The identity of the hypervisor, if needed, can be tested by testing
the pointer value in x86_hyper.

The MS-HyperV private state is moved into a normal global variable
(it's per-system state, not per-CPU state).  Being a normal bss
variable, it will be left at all zero on non-HyperV platforms, and so
can generally be tested for HyperV-specific features without
additional qualification.

ab608344bc perf, x86: Improve the PEBS ABI
Rename perf_event_attr::precise to perf_event_attr::precise_ip and
widen it to 2 bits. This new field describes the required precision of
the PERF_SAMPLE_IP field:

  0 - SAMPLE_IP can have arbitrary skid
  1 - SAMPLE_IP must have constant skid
  2 - SAMPLE_IP requested to have 0 skid
  3 - SAMPLE_IP must have 0 skid

And modify the Intel PEBS code accordingly. The PEBS implementation
now supports up to precise_ip == 2, where we perform the IP fixup.

Also s/PERF_RECORD_MISC_EXACT/&_IP/ to clarify its meaning, this bit
should be set for each PERF_SAMPLE_IP field known to match the actual
instruction triggering the event.

This new scheme allows for a PEBS mode that uses the buffer for more
than a single event.

243bc65447 davinci: edma: fix coding style issue related to usage of braces
In the edma driver, there are couple of instances where braces
are used for a single statement 'if' construct.

There are other instances where 'else' part of the if-else construct
does not use braces even if the 'if' part is a multi-line statement.

This patch fixes both.

c78a5bc2e7 Davinci: watchdog reset separation across socs
The earlier watchdog reset mechanism had a couple of limitations.  First, it
embedded a reference to "davinci_wdt_device" inside common code.  This
forced all derived platforms (da8xx and tnetv107x) to define such a device.
This also would have caused problems in including multiple socs in a single
build due to symbol redefinition.

With this patch, davinci_watchdog_reset() now takes the platform device as an
argument.  The davinci_soc_info struct has been extended to include a reset
function and a watchdog platform_device.  arch_reset() then uses these
elements to reset the system in a SoC specific fashion.

This patch renders the inlined gpio accessors in gpio.h independent of the
underlying controller's register layout.  This is done by including three new
fields in davinci_gpio_controller to hold the addresses of the set, clear, and

Other changes:

1. davinci_gpio_regs structure definition moved to gpio.c.  This structure is
no longer common across all davinci socs (davinci_gpio_controller is).

2. controller base address calculation code (gpio2controller()) moved to
gpio.c as this was no longer necessary for the inline implementation.

3. modified inline range checks to use davinci_soc_info.gpio_num instead of
DAVINCI_N_GPIO.

a7e05065f5 davinci: edma: clear interrupt status for interrupt enabled channels only
Currently, the ISR in the EDMA driver clears the pending interrupt for all
channels without regard to whether that channel has a registered callback
or not.

This causes problems for devices like DM355/DM365 where the multimedia
accelerator uses EDMA by polling on the interrupt pending bits of some of the
EDMA channels. Since these channels are actually allocated through the Linux
EDMA driver (by an out-of-kernel module), the same shadow region is used by
Linux and accelerator. There a race between the Linux ISR and the polling code
running on the accelerator on the IPR (interrupt pending register).

This patch fixes the issue by making the ISR clear the interrupts only for
those channels which have interrupt enabled. The channels which are allocated
for the purpose of being polled on by the accelerator will not have a callback
function provided and so will not have IER (interrupt enable register) bits set.

Tested on DM365 and OMAP-L137/L138 with audio and MMC/SD (as EDMA users).
