b96fc2f3c1 ARM: Remove __ref on hotplug cpu die path
Now that __cpuinit has been removed, the __ref markings on these
functions are useless. Remove them. This also reduces the size of
the multi_v7_defconfig image:

$ size before after
   text    data     bss     dec     hex filename
   12683578        1470996  348904 14503478         dd4e36 before
   12683274        1470996  348904 14503174         dd4d06 after

presumably because now we don't have to jump to code in the
.ref.text section and/or the noinline marking is removed.

 - Remove VoiceBlue board support as it's been unused over
   10 years now
 
 - Remove unused polarity control macros for TWL
 
 - Remove two unneeded semicolons
 
 - Remove unused core dpll code for reprogramming the rates
 
 Note that this branch is against v4.3-rc4 as that contains critical
 MMC related fixes to boot with MMC working on most omaps.

safer way inside the common ARM startup code.

initially required this, is no more supported]

d42f265a5d ARM: OMAP3: clock: remove un-used core dpll re-program code
Remove the OMAP3 core DPLL re-program code, and the associated SRAM
code that does the low-level programming of the DPLL divider, idling
of the SDRAM etc.

This code was never fully implemented in the kernel; things missing
were driver side handling of core clock changes (they need to account
for their functional clock rate being changed on-the-fly), and the whole
framework required for handling this. Thus, there is not much point
to keep carrying the low-level support code either.

Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:
 "Our first real batch of fixes this release cycle.  Nothing really
  concerning, and diffstat is a bit inflated due to some DT contents
  moving around on STi platforms.

  There's a collection of them here:

   - A fixup for a build breakage that hits on arm64 allmodconfig in
     QCOM SCM firmware drivers
   - MMC fixes for OMAP that had quite a bit of breakage this merge
     window.
   - Misc build/warning fixes on PXA and OMAP
   - A couple of minor fixes for Beagleboard X15 which is now starting
     to see a few more users in the wild"

9a5e3f27d1 ARM: dts: fix omap2+ address translation for pbias
"ARM: dts: <omap2/omap4/omap5/dra7>: add minimal l4 bus
layout with control module support" moved pbias_regulator dt node
from being a child node of ocp to be the child node of
'syscon'. Since 'syscon' doesn't have the 'ranges' property,
address translation fails while trying to convert the address
to resource. Fix it here by populating 'ranges' property in
syscon dt node.

This is caused by the alignment handler not being fixed up for the

ef748917b5 arm/arm64: KVM: Remove 'config KVM_ARM_MAX_VCPUS'
This patch removes config option of KVM_ARM_MAX_VCPUS,
and like other ARCHs, just choose the maximum allowed
value from hardware, and follows the reasons:

1) from distribution view, the option has to be
defined as the max allowed value because it need to
meet all kinds of virtulization applications and
need to support most of SoCs;

2) using a bigger value doesn't introduce extra memory
consumption, and the help text in Kconfig isn't accurate
because kvm_vpu structure isn't allocated until request
of creating VCPU is sent from QEMU;

3) the main effect is that the field of vcpus[] in 'struct kvm'
becomes a bit bigger(sizeof(void *) per vcpu) and need more cache
lines to hold the structure, but 'struct kvm' is one generic struct,
and it has worked well on other ARCHs already in this way. Also,
the world switch frequecy is often low, for example, it is ~2000
when running kernel building load in VM from APM xgene KVM host,
so the effect is very small, and the difference can't be observed
in my test at all.

688bc577ac arm: KVM: Disable virtual timer even if the guest is not using it
When running a guest with the architected timer disabled (with QEMU and
the kernel_irqchip=off option, for example), it is important to make
sure the timer gets turned off. Otherwise, the guest may try to
enable it anyway, leading to a screaming HW interrupt.

The fix is to unconditionally turn off the virtual timer on guest
exit.

5005296e74 ARM: dts: am57xx-beagle-x15: Update Phy supplies
Originally, all the SoC PHY rails were supplied by LDO3. However, as a
result of characterization, it was determined that this posed a risk in
extreme load  conditions. Hence the PHY rails are split between two
different LDOs. Update the related node as a result

LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3
LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie

NOTE: We break compatibility with pre-production boards with this change
since, the PMIC LDO4 is disabled at OTP level.

The new configuration is the plan of record and all pre-production
boards are supposed to be replaced with the latest boards matching the
mentioned configuration.

Some very few 10 something boards have been created and
stopped production till the latest modifications were done (PMIC USB
interrupt, LDO4 etc) - and all of those boards are now getting
scrapped.. If there are any (as per tracking information, there should
not be any), TI should be contacted to have them replaced.

7ae85dc768 ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints
In (23a4e40 arm: kgdb: Handle read-only text / modules) we moved to
using patch_text() to set breakpoints so that we could handle the case
when we had CONFIG_DEBUG_RODATA.  That patch used patch_text().
Unfortunately, patch_text() assumes that we're not in atomic context
when it runs since it needs to grab a mutex and also wait for other
CPUs to stop (which it does with a completion).

This would result in a stack crawl if you had
CONFIG_DEBUG_ATOMIC_SLEEP and tried to set a breakpoint in kgdb.  The
crawl looked something like:

 BUG: scheduling while atomic: swapper/0/0/0x00010007

It turns out that when we're in kgdb all the CPUs are stopped anyway
so there's no reason we should be calling patch_text().  We can
instead directly call __patch_text() which assumes that CPUs have
already been stopped.

c2f58514cf arm/arm64: KVM: vgic: Check for !irqchip_in_kernel() when mapping resources
Until b26e5fdac4 ("arm/arm64: KVM: introduce per-VM ops"),
kvm_vgic_map_resources() used to include a check on irqchip_in_kernel(),
and vgic_v2_map_resources() still has it.

But now vm_ops are not initialized until we call kvm_vgic_create().
Therefore kvm_vgic_map_resources() can being called without a VGIC,
and we die because vm_ops.map_resources is NULL.

Fixing this restores QEMU's kernel-irqchip=off option to a working state,
allowing to use GIC emulation in userspace.

ca09f02f12 arm: KVM: Fix incorrect device to IPA mapping
A critical bug has been found in device memory stage1 translation for
VMs with more then 4GB of address space. Once vm_pgoff size is smaller
then pa (which is true for LPAE case, u32 and u64 respectively) some
more significant bits of pa may be lost as a shift operation is performed
on u32 and later cast onto u64.

Example: vm_pgoff(u32)=0x00210030, PAGE_SHIFT=12
        expected pa(u64):   0x0000002010030000
        produced pa(u64):   0x0000000010030000

The fix is to change the order of operations (casting first onto phys_addr_t
and then shifting).
