7f4d3641e2 ARM: OMAP3: hwmod data: Don't prevent RESET of USB Host module
Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.

RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.

313a76ee11 ARM: OMAP2+: hwmod: Fix SOFTRESET logic
In _ocp_softreset(), after _set_softreset() + write_sysconfig(),
the hwmod's sysc_cache will always contain SOFTRESET bit set
so all further writes to sysconfig using this cache will initiate
a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like
platforms that have RESET_DONE status in the SYSSTATUS register and
so the the SOFTRESET bit in SYSCONFIG is not automatically cleared.
It is not a problem for OMAP4 like platforms that indicate RESET
completion by clearing the SOFTRESET bit in the SYSCONFIG register.

This repeated SOFTRESET is undesired and was the root cause of
USB host issues on OMAP3 platforms when hwmod was allowed to do the
SOFTRESET for the USB Host module.

To fix this we clear the SOFTRESET bit and update the sysconfig
register + sysc_cache using write_sysconfig().

 Nothing major, but we seem to have an argument about a XHCI fix, so I'm not
 including a revert that Sarah requested, because that breaks a USB network
 driver, and I can't revert the USB network driver fix without reintroducing
 other bugs that it fixed.  So as it is, everything should now be
 working.  Worse case, I can revert the XHCI fix before 3.13-final is
 out, but it seems to work well here with my testing, so all should be
 good.
 
 Other than that, some driver updates based on reports.

the 'soc' node in the common .dtsi for MPC5121 has an '#interrupt-cells'

remove this erroneously placed property because starting with v3.13-rc1
lookup and resolution of 'interrupts' specs for peripherals gets misled,
emits 'no irq domain found' WARN() messages and breaks the boot process

Let's fix the issue by adding omap34xx-hs.dtsi and omap36xx-hs.dtsi and make
n900, n9 and n950 to use them. This way we have the aes, sham and timer12
disabled for secure devices the same way legacy booting does based on the
omap34xx_gp_hwmod_ocp_ifs and omap36xx_gp_hwmod_ocp_ifs arrays in
omap_hwmod_3xxx_data.c.

5e863c5610 ARM: OMAP2+: Fix overwriting hwmod data with data from device tree
We have some device tree properties where the ti,hwmod have multiple
values:

am33xx.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi:	ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi:	ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";

That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.

So they should all be fixed up to be separate devices in the .dts files.

We also have the related data removed for at least omap4 in commit
3b9b10151c (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.

So we need to fix two bugs:

1. We are only checking the first entry of the ti,hwmods property

   This means that we're only initializing the first hwmods entry
   instead of the ones listed in the ti,hwmods property.

2. We are only checking the child nodes, not the nodes themselves

   This means that anything listed at OCP level is currently just
   ignored and unitialized and at least the omap4 case, with the
   legacy data missing from the hwmod.

Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.

While at it, let's also add some warnings for the bad data so it's
easier to fix.

85cc00eaa8 arm64: kernel: add code to set cpu boot mode to secondary_entry shim
The refactoring of el2_setup split code setting up EL2 and detecting the
CPU boot mode in separate chunks. This allows the code that sets up EL2 to
run in an endian independent way - ie before the endianess is set up in
the respective sctlr registers.

This patch brings secondary_entry up-to-date so that CPUs entering the
kernel through this code path set-up EL2 and the cpu boot mode properly.

3cea71bc6b arm64: ensure completion of TLB invalidatation
Currently there is no dsb between the tlbi in __cpu_setup and the write
to SCTLR_EL1 which enables the MMU in __turn_mmu_on. This means that the
TLB invalidation is not guaranteed to have completed at the point
address translation is enabled, leading to a number of possible issues
including incorrect translations and TLB conflict faults.

This patch moves the tlbi in __cpu_setup above an existing dsb used to
synchronise I-cache invalidation, ensuring that the TLBs have been
invalidated at the point the MMU is enabled.

a44a9791e7 iommu/arm-smmu: use mutex instead of spinlock for locking page tables
When creating IO mappings, we lazily allocate our page tables using the
standard, non-atomic allocator functions. This presents us with a
problem, since our page tables are protected with a spinlock.

This patch reworks the smmu_domain lock to use a mutex instead of a
spinlock. iova_to_phys is then reworked so that it only reads the page
tables, and can run in a lockless fashion, leaving the mutex to guard
against concurrent mapping threads.

843f4f4bb1 A regression showed up that there's a large delay when enabling
all events. This was prevalent when FTRACE_SELFTEST was enabled which
 enables all events several times, and caused the system bootup to
 pause for over a minute.
 
 This was tracked down to an addition of a synchronize_sched() performed
 when system call tracepoints are unregistered.
 
 The synchronize_sched() is needed between the unregistering of the
 system call tracepoint and a deletion of a tracing instance buffer.
 But placing the synchronize_sched() in the unreg of *every* system call
 tracepoint is a bit overboard. A single synchronize_sched() before
 the deletion of the instance is sufficient.

7adfff587b SCSI fixes on 20131206
This is a set of nine fixes (and one author update). The libsas one should fix
 discovery in eSATA devices, the WRITE_SAME one is the largest, but it should
 fix a lot of problems we've been getting with the emulated RAID devices
 (they've been effectively lying about support and then firmware has been
 choking on the commands).  The rest are various crash, hang or warn driver
 fixes.

features in userspace. Therefore this quirk can be removed.

    suspend error.

    resume from hibernation broken in 3.12.  From Dmitry Torokhov.
 
  - cpuidle fix to prevent cpuidle device unregistration from crashing
    due to a NULL pointer dereference if cpuidle has been disabled
    from the kernel command line.  From Konrad Rzeszutek Wilk.

  - Power capping framework fix to make the energy_uj sysfs attribute
    work in accordance with the documentation.  From Srinivas Pandruvada.
 
  - epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
    been compiled with CONFIG_PM_SLEEP unset (in which case that flag
    should not have any effect).  From Amit Pundir.
 
  - cpufreq fix to prevent governor sysfs files from being lost over
    system suspend/resume in some (arguably unusual) situations.  From
