Add support for per-processor bug checking - each processor function
descriptor gains a function pointer for this check, which must not be
an __init function.  If non-NULL, this will be called whenever a CPU
enters the kernel via which ever path (boot CPU, secondary CPU startup,
CPU resuming, etc.)

This allows processor specific bug checks to validate that workaround
bits are properly enabled by firmware via all entry paths to the kernel.

c2e415fe75 crypto: clarify licensing of OpenSSL asm code
Several source files have been taken from OpenSSL. In some of them a
comment that "permission to use under GPL terms is granted" was
included below a contradictory license statement. In several cases,
there was no indication that the license of the code was compatible
with the GPLv2.

This change clarifies the licensing for all of these files. I've
confirmed with the author (Andy Polyakov) that a) he has licensed the
files with the GPLv2 comment under that license and b) that he's also
happy to license the other files under GPLv2 too. In one case, the
file is already contained in his CRYPTOGAMS bundle, which has a GPLv2
option, and so no special measures are needed.

In all cases, the license status of code has been clarified by making
the GPLv2 license prominent.

The .S files have been regenerated from the updated .pl files.

This is a comment-only change. No code is changed.

regulator: gpio: Get enable GPIO using GPIO descriptor
We augment the GPIO regulator to get the *enable* regulator
GPIO line (not the other lines) using a descriptor rather than

We then pass this into the regulator core which has been
prepared to hande enable descriptors in a separate patch.

Switch over the two boardfiles using this facility and clean
up so we only pass descriptors around.

regulator: fixed: Convert to use GPIO descriptor only
As we augmented the regulator core to accept a GPIO descriptor instead
of a GPIO number, we can augment the fixed GPIO regulator to look up
and pass that descriptor directly from device tree or board GPIO
descriptor look up tables.

Some boards just auto-enumerate their fixed regulator platform devices
and I have assumed they get names like "fixed-regulator.0" but it's
pretty hard to guess this. I need some testing from board maintainers to
be sure. Other boards are straight forward, using just plain
"fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the
device ID.

The OMAP didn't have proper label names on its GPIO chips so I have fixed
this with a separate patch to the GPIO tree, see
commit 088413bc0b
"gpio: omap: Give unique labels to each GPIO bank/chip"

It seems the da9055 and da9211 has never got around to actually passing
any enable gpio into its platform data (not the in-tree code anyway) so we
can just decide to simply pass a descriptor instead.

The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named
"*_dummy_supply_device" while it is a very real device backed by a GPIO
line. There is nothing dummy about it at all, so I renamed it with the
infix *_regulator_* as part of this patch set.

For the patch hunk hitting arch/blackfin I would say I do not expect
testing, review or ACKs anymore so if it works, it works.

The hunk hitting the x86 BCM43xx driver is especially tricky as the number
comes out of SFI which is a mystery to me. I definately need someone to
look at this. (Hi Andy.)

f59c303b59 ARM: Fix i2c-gpio GPIO descriptor tables
I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".

But several had it set to >=0 which gives the names
"i2c-gpio.0", "i2c-gpio.1" ...

Fix the offending instances in the ARM tree. Sorry for the
mess.

The patch that enabled these had no useful changelog that explains
why it is done, and it causes a build warning:

WARNING: unmet direct dependencies detected for STM32_DMA
  Depends on [n]: DMADEVICES [=n] && (ARCH_STM32 [=y] || COMPILE_TEST [=y])
  Selected by [y]:

Generally, platforms should not select arbitrary drivers, so let's
just revert that change.

bd6cc4f2d2 Late omap soc changes for v4.18 merge window
This series contains two omap1 ams-delta GPIO clean-up patches to get
 started with removal of hard-coded GPIO numbers from drivers. And then
 the removal of board mach includes from drivers. The second patch mostly
 touches the ams-delta audio driver but is included here because of the
 removal of the latch gpios and is acked by Mark Brown.
 
 And there are two more am437x related PM patches to save and restore
 control module and timer registers for RTC only suspend mode. Looks like
 the patch title for the timer changes is a bit misleading, not all the
 timer code is yet living under drivers/clocksource. But I had already
 pushed out the branch before I noticed this.

33d2f13135 Allwinner H3/H5 support for 4.18
Here is our usual bunch of changes for the H3 and H5 SoCs that share the
 same SoC design but with different CPUs.
 
 This time, most of the changes are about supporting CPUFreq on these SoCs,
 with voltage scaling being enabled for a number of boards.

We want to work towards phasing out the at24_platform_data structure.
There are few users and its contents can be represented using generic
device properties. Using device properties only will allow us to
significantly simplify the at24 configuration code.

Remove the at24_platform_data structure and replace it with an array
of property entries. Drop the byte_len/size property, as the model name
already implies the EEPROM's size.

 been acked by NAND maintainer and because of the driver dependency
 an immutable branch has been provided to Boris.
 
 The other patch is to remove an unnecessary postcore_initcall() on

21cdd7fd76 KVM: arm64: Remove eager host SVE state saving
Now that the host SVE context can be saved on demand from Hyp,
there is no longer any need to save this state in advance before
entering the guest.

This patch removes the relevant call to
kvm_fpsimd_flush_cpu_state().

Since the problem that function was intended to solve now no longer
exists, the function and its dependencies are also deleted.

path.  This means that it is no longer necessary to save the host
SVE state in advance of entering the guest, when in use.

In order to avoid adding pointless complexity to the code, VHE is
assumed if SVE is in use.  VHE is an architectural prerequisite for
SVE, so there is no good reason to turn CONFIG_ARM64_VHE off in
kernels that support both SVE and KVM.

Historically, software models exist that can expose the
architecturally invalid configuration of SVE without VHE, so if
this situation is detected at kvm_init() time then KVM will be
disabled.

e6b673b741 KVM: arm64: Optimise FPSIMD handling to reduce guest/host thrashing
This patch refactors KVM to align the host and guest FPSIMD
save/restore logic with each other for arm64.  This reduces the
number of redundant save/restore operations that must occur, and
reduces the common-case IRQ blackout time during guest exit storms
by saving the host state lazily and optimising away the need to
restore the host state before returning to the run loop.

Four hooks are defined in order to enable this:

 * kvm_arch_vcpu_run_map_fp():
   Called on PID change to map necessary bits of current to Hyp.

 * kvm_arch_vcpu_load_fp():
   Set up FP/SIMD for entering the KVM run loop (parse as
   "vcpu_load fp").

 * kvm_arch_vcpu_ctxsync_fp():
   Get FP/SIMD into a safe state for re-enabling interrupts after a
   guest exit back to the run loop.

   For arm64 specifically, this involves updating the host kernel's
   FPSIMD context tracking metadata so that kernel-mode NEON use
   will cause the vcpu's FPSIMD state to be saved back correctly
   into the vcpu struct.  This must be done before re-enabling
   interrupts because kernel-mode NEON may be used by softirqs.

 * kvm_arch_vcpu_put_fp():
   Save guest FP/SIMD state back to memory and dissociate from the
   CPU ("vcpu_put fp").

Also, the arm64 FPSIMD context switch code is updated to enable it
to save back FPSIMD state for a vcpu, not just current.  A few
helpers drive this:

 * fpsimd_bind_state_to_cpu(struct user_fpsimd_state *fp):
   mark this CPU as having context fp (which may belong to a vcpu)
   currently loaded in its registers.  This is the non-task
   equivalent of the static function fpsimd_bind_to_cpu() in
   fpsimd.c.

 * task_fpsimd_save():
   exported to allow KVM to save the guest's FPSIMD state back to
   memory on exit from the run loop.

 * fpsimd_flush_state():
   invalidate any context's FPSIMD state that is currently loaded.
   Used to disassociate the vcpu from the CPU regs on run loop exit.

These changes allow the run loop to enable interrupts (and thus
softirqs that may use kernel-mode NEON) without having to save the
guest's FPSIMD state eagerly.

Some new vcpu_arch fields are added to make all this work.  Because
host FPSIMD state can now be saved back directly into current's
thread_struct as appropriate, host_cpu_context is no longer used
for preserving the FPSIMD state.  However, it is still needed for
preserving other things such as the host's system registers.  To
avoid ABI churn, the redundant storage space in host_cpu_context is
not removed for now.

arch/arm is not addressed by this patch and continues to use its
current save/restore logic.  It could provide implementations of
the helpers later if desired.

ac6e31d35f ARM: dts: Add Aspeed SoC USB controllers to device-tree
This adds the USB controllers to the DT template of the
AST24xx and AST25xx SoCs.

This patch doesn't enable them by default on any board specific
.dts yet. This will be done when we have the necessary clock/reset
and pinmux support. In the meantime though, this will work if
u-boot configures things properly.

For the AST2400 I only added pinmux definition for port 1
which is dual USB1/USB2. There are additional USB1 only ports
that might require more work but I don't have HW to test at
hand so I'm leaving that to whoever cares.

The reason for this error is that the span of MOVABLE_ZONE is extended

another problem happened.

It's so late time to fix the later problem so I decide to reverting the
