f98121f3ef arm64: dts: fix build errors from missing dependencies
Two branches were incorrectly sent without having the necessary
header file changes. Rather than back those out now, I'm replacing
the symbolic names for the clks and resets with the numeric
values to get 'make allmodconfig dtbs' back to work.

After the header file changes are merged, we can revert this
patch.

1650ac49c2 arm64: head.S: Fix CNTHCTL_EL2 access on VHE system
Bit positions of CNTHCTL_EL2 are changing depending on HCR_EL2.E2H bit.
EL1PCEN and EL1PCTEN are 1st and 0th bits when E2H is not set, but they
are 11th and 10th bits respectively when E2H is set.  Current code is
unintentionally setting wrong bits to CNTHCTL_EL2 with E2H set.

In fact, we don't need to set those two bits, which allow EL1 and EL0 to
access physical timer and counter respectively, if E2H and TGE are set
for the host kernel. They will be configured later as necessary. First,
we don't need to configure those bits for EL1, since the host kernel
runs in EL2.  It is a hypervisor's responsibility to configure them
before entering a VM, which runs in EL0 and EL1. Second, EL0 accesses
are configured in the later stage of boot process.

7918ecef07 crypto: arm64/sha2 - integrate OpenSSL implementations of SHA256/SHA512
This integrates both the accelerated scalar and the NEON implementations
of SHA-224/256 as well as SHA-384/512 from the OpenSSL project.

Relative performance compared to the respective generic C versions:

                 |  SHA256-scalar  | SHA256-NEON* |  SHA512  |
     ------------+-----------------+--------------+----------+
     Cortex-A53  |      1.63x      |     1.63x    |   2.34x  |
     Cortex-A57  |      1.43x      |     1.59x    |   1.95x  |
     Cortex-A73  |      1.26x      |     1.56x    |     ?    |

The core crypto code was authored by Andy Polyakov of the OpenSSL
project, in collaboration with whom the upstream code was adapted so
that this module can be built from the same version of sha512-armv8.pl.

The version in this patch was taken from OpenSSL commit 32bbb62ea634
("sha/asm/sha512-armv8.pl: fix big-endian support in __KERNEL__ case.")

* The core SHA algorithm is fundamentally sequential, but there is a
  secondary transformation involved, called the schedule update, which
  can be performed independently. The NEON version of SHA-224/SHA-256
  only implements this part of the algorithm using NEON instructions,
  the sequential part is always done using scalar instructions.

ee6a7fce8e arm64: Remove I-cache invalidation from flush_cache_range()
The flush_cache_range() function (similarly for flush_cache_page()) is
called when the kernel is changing an existing VA->PA mapping range to
either a new PA or to different attributes. Since ARMv8 has PIPT-like
D-caches, this function does not need to perform any D-cache
maintenance. The I-cache maintenance is already handled via set_pte_at()
and flush_cache_range() cannot anyway guarantee that there are no cache
lines left after invalidation due to the speculative loads.

This patch makes flush_cache_range() a no-op.

Then adds a meson-gxm dtsi and reproduce the P23x to Q20x boards

f9aa9dc7d2 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
All conflicts were simple overlapping changes except perhaps
for the Thunder driver.

That driver has a change_mtu method explicitly for sending
a message to the hardware.  If that fails it returns an
error.

Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.

However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

This patch adds the Kconfig option to enable support for TTBR0 PAN
emulation. The option is default off because of a slight performance hit
when enabled, caused by the additional TTBR0_EL1 switching during user
access operations or exception entry/exit code.

9cf09d68b8 arm64: xen: Enable user access before a privcmd hvc call
Privcmd calls are issued by the userspace. The kernel needs to enable
access to TTBR0_EL1 as the hypervisor would issue stage 1 translations
to user memory via AT instructions. Since AT instructions are not
affected by the PAN bit (ARMv8.1), we only need the explicit
uaccess_enable/disable if the TTBR0 PAN option is enabled.

786889636a arm64: Handle faults caused by inadvertent user access with PAN enabled
When TTBR0_EL1 is set to the reserved page, an erroneous kernel access
to user space would generate a translation fault. This patch adds the

39bc88e5e3 arm64: Disable TTBR0_EL1 during normal kernel execution
When the TTBR0 PAN feature is enabled, the kernel entry points need to
disable access to TTBR0_EL1. The PAN status of the interrupted context
is stored as part of the saved pstate, reusing the PSR_PAN_BIT (22).
Restoring access to TTBR0_EL1 is done on exception return if returning
to user or returning to a context where PAN was disabled.

Context switching via switch_mm() must defer the update of TTBR0_EL1
until a return to user or an explicit uaccess_enable() call.

Special care needs to be taken for two cases where TTBR0_EL1 is set
outside the normal kernel context switch operation: EFI run-time
services (via efi_set_pgd) and CPU suspend (via cpu_(un)install_idmap).
Code has been added to avoid deferred TTBR0_EL1 switching as in
switch_mm() and restore the reserved TTBR0_EL1 when uninstalling the
special TTBR0_EL1.

User cache maintenance (user_cache_maint_handler and
__flush_cache_user_range) needs the TTBR0_EL1 re-instated since the
operations are performed by user virtual address.

This patch also removes a stale comment on the switch_mm() function.

4b65a5db36 arm64: Introduce uaccess_{disable,enable} functionality based on TTBR0_EL1
This patch adds the uaccess macros/functions to disable access to user
space by setting TTBR0_EL1 to a reserved zeroed page. Since the value
written to TTBR0_EL1 must be a physical address, for simplicity this
patch introduces a reserved_ttbr0 page at a constant offset from
swapper_pg_dir. The uaccess_disable code uses the ttbr1_el1 value
adjusted by the reserved_ttbr0 offset.

Enabling access to user is done by restoring TTBR0_EL1 with the value
from the struct thread_info ttbr0 variable. Interrupts must be disabled
during the uaccess_ttbr0_enable code to ensure the atomicity of the
thread_info.ttbr0 read and TTBR0_EL1 write. This patch also moves the
get_thread_info asm macro from entry.S to assembler.h for reuse in the
uaccess_ttbr0_* macros.

Note that any (unlikely) access that the compiler might generate between

such.

77079b133f ARM: SoC fixes for v4.9-rc
Again a set of smaller fixes across several platforms (OMAP, Marvell,
 Allwinner, i.MX, etc).
 
 A handful of typo fixes and smaller missing contents from device trees,
 with some tweaks to OMAP mach files to deal with CPU feature print
 misformatting, potential NULL ptr dereference and one setup issue
 with UARTs.

310aa13495 Topic branch with DT arm64 changes for v4.10.
Fix invalid GIC interrupt flags - type IRQ_TYPE_NONE is not allowed for GIC
 interrupts.  Although this was working but with error messages like:
         genirq: Setting trigger mode 0 for irq 16 failed
 
 Use level high interrupt instead of type none.  The choice of level high was
 rather an arbitrary decision hoping it will work on each platform.  Tests shown
 no issues so far.

fdfeff0f9e arm64: hw_breakpoint: Handle inexact watchpoint addresses
Arm64 hardware does not always report a watchpoint hit address that
matches one of the watchpoints set. It can also report an address
"near" the watchpoint if a single instruction access both watched and
unwatched addresses. There is no straight-forward way, short of
disassembling the offending instruction, to map that address back to
the watchpoint.

Previously, when the hardware reported a watchpoint hit on an address
that did not match our watchpoint (this happens in case of instructions
which access large chunks of memory such as "stp") the process would
enter a loop where we would be continually resuming it (because we did
not recognise that watchpoint hit) and it would keep hitting the
watchpoint again and again. The tracing process would never get
notified of the watchpoint hit.

This commit fixes the problem by looking at the watchpoints near the
address reported by the hardware. If the address does not exactly match
one of the watchpoints we have set, it attributes the hit to the
nearest watchpoint we have.  This heuristic is a bit dodgy, but I don't
think we can do much more, given the hardware limitations.

b08fb180bb arm64: Allow hw watchpoint at varied offset from base address
ARM64 hardware supports watchpoint at any double word aligned address.
However, it can select any consecutive bytes from offset 0 to 7 from that
base address. For example, if base address is programmed as 0x420030 and
byte select is 0x1C, then access of 0x420032,0x420033 and 0x420034 will
generate a watchpoint exception.

Currently, we do not have such modularity. We can only program byte,
halfword, word and double word access exception from any base address.

This patch adds support to overcome above limitations.

 Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
 second (22.5%). The remaining 9.3% are scattered on gadget drivers.
 
 The most important changes for dwc2 are the peripheral side DMA support
 implemented by Synopsys folks and support for the new IOT dwc2
 compatible core from Synopsys.
 
 In dwc3 land we have support for high-bandwidth, high-speed isochronous
 endpoints and some non-critical fixes for large scatter lists.
 
 Apart from these, we have our usual set of cleanups, non-critical fixes,

UART3 device is not really needed for enabling audio block on TM2.
Enabling it made it working by enabling some common parent clocks,
what is now handled by improved exynos5433 clocks driver. Thus the UART3
device node can be safely disabled. The assigned-clocks entries are
however still needed, so move them under the respective CMU node.

cebef6be66 arm64: dts: exynos: Fix IRQ type flags for Exynos5433 SoC
Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts. The
GIC requires shared interrupts to be edge rising or level high. Platform
declares support for both. Set all interrupts type to level high, as this
works fine - tested on Exynos5433-based TM2 board.

b112c84a6f KVM: arm64: Fix the issues when guest PMCCFILTR is configured
KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured.
But this function can't deals with PMCCFILTR correctly because the evtCount
bits of PMCCFILTR, which is reserved 0, conflits with the SW_INCR event
type of other PMXEVTYPER<n> registers. To fix it, when eventsel == 0, this
function shouldn't return immediately; instead it needs to check further
if select_idx is ARMV8_PMU_CYCLE_IDX.

Another issue is that KVM shouldn't copy the eventsel bits of PMCCFILTER
blindly to attr.config. Instead it ought to convert the request to the
"cpu cycle" event type (i.e. 0x11).

To support this patch and to prevent duplicated definitions, a limited
set of ARMv8 perf event types were relocated from perf_event.c to
asm/perf_event.h.

82e0191a1a arm64: Support systems without FP/ASIMD
The arm64 kernel assumes that FP/ASIMD units are always present
and accesses the FP/ASIMD specific registers unconditionally. This
could cause problems when they are absent. This patch adds the
support for kernel handling systems without FP/ASIMD by skipping the
register access within the kernel. For kvm, we trap the accesses
to FP/ASIMD and inject an undefined instruction exception to the VM.

The callers of the exported kernel_neon_begin_partial() should
make sure that the FP/ASIMD is supported.

a4023f6827 arm64: Add hypervisor safe helper for checking constant capabilities
The hypervisor may not have full access to the kernel data structures
and hence cannot safely use cpus_have_cap() helper for checking the
system capability. Add a safe helper for hypervisors to check a constant
system capability, which *doesn't* fall back to checking the bitmap
maintained by the kernel. With this, make the cpus_have_cap() only
check the bitmask and force constant cap checks to use the new API
for quicker checks.

79ab11cdb9 locking/core: Introduce cpu_relax_yield()
For spinning loops people do often use barrier() or cpu_relax().
For most architectures cpu_relax and barrier are the same, but on
some architectures cpu_relax can add some latency.
For example on power,sparc64 and arc, cpu_relax can shift the CPU
towards other hardware threads in an SMT environment.
On s390 cpu_relax does even more, it uses an hypercall to the
hypervisor to give up the timeslice.
In contrast to the SMT yielding this can result in larger latencies.
In some places this latency is unwanted, so another variant
"cpu_relax_lowlatency" was introduced. Before this is used in more
and more places, lets revert the logic and provide a cpu_relax_yield
that can be called in places where yielding is more important than
latency. By default this is the same as cpu_relax on all architectures.

ab5b24fdd2 ARM64: dts: meson-gxbb-vega-s95: Add SD/SDIO/MMC and PWM nodes
All boards from the Tronsmart Vega S95 series are sharing similar MMC
based hardware.
sd_emmc_a is used to connect a Broadcom based SDIO wifi card (supported
by the brcmfmac driver). The 32.768KHz LPO clock for the wifi chip is
generated by PWM_E.
sd_emmc_b is routed to the SD-card. Unlike p20x there is no GPIO
regulator, meaning it only supports 3.3V (which seems to be hard-wired).
The eMMC chip is connected to sd_emmc_c and is implemented similar to
the meson-gxbb-p20x boards (meaning that hard-wired fixed regulators
are used).

3552fdf29f efi: Allow bitness-agnostic protocol calls
We already have a macro to invoke boot services which on x86 adapts
automatically to the bitness of the EFI firmware:  efi_call_early().

The macro allows sharing of functions across arches and bitness variants
as long as those functions only call boot services.  However in practice
functions in the EFI stub contain a mix of boot services calls and
protocol calls.

Add an efi_call_proto() macro for bitness-agnostic protocol calls to
allow sharing more code across arches as well as deduplicating 32 bit
and 64 bit code paths.

On x86, implement it using a new efi_table_attr() macro for bitness-
agnostic table lookups.  Refactor efi_call_early() to make use of the
same macro.  (The resulting object code remains identical.)

While debugging a kernel image size issue, I discovered that if all
non ARCH_QCOM configs in the ARM64 defconfig are disabled, the QCOM
pinctrl drivers will not be built.

The QCOM pinctrl drivers have a dependency on GPIOLIB which was being
selected when other ARCH configs were enabled, but ARCH_QCOM doesn't
select GPIOLIB directly.  Let's select GPIOLIB here to ensure the pinctrl
drivers are built for QCOM platforms.

c02433dd6d arm64: split thread_info from task stack
This patch moves arm64's struct thread_info from the task stack into
task_struct. This protects thread_info from corruption in the case of
stack overflows, and makes its address harder to determine if stack
addresses are leaked, making a number of attacks more difficult. Precise
detection and handling of overflow is left for subsequent patches.

Largely, this involves changing code to store the task_struct in sp_el0,
and acquire the thread_info from the task struct. Core code now
implements current_thread_info(), and as noted in <linux/sched.h> this
relies on offsetof(task_struct, thread_info) == 0, enforced by core
code.

This change means that the 'tsk' register used in entry.S now points to
a task_struct, rather than a thread_info as it used to. To make this
clear, the TI_* field offsets are renamed to TSK_TI_*, with asm-offsets
appropriately updated to account for the structural change.

Userspace clobbers sp_el0, and we can no longer restore this from the
stack. Instead, the current task is cached in a per-cpu variable that we
can safely access from early assembly as interrupts are disabled (and we
are thus not preemptible).

Both secondary entry and idle are updated to stash the sp and task
pointer separately.

1b7e2296a8 arm64: assembler: introduce ldr_this_cpu
Shortly we will want to load a percpu variable in the return from
userspace path. We can save an instruction by folding the addition of
the percpu offset into the load instruction, and this patch adds a new
helper to do so.

At the same time, we clean up this_cpu_ptr for consistency. As with
{adr,ldr,str}_l, we change the template to take the destination register
first, and name this dst. Secondly, we rename the macro to adr_this_cpu,
following the scheme of adr_l, and matching the newly added
ldr_this_cpu.

57c82954e7 arm64: make cpu number a percpu variable
In the absence of CONFIG_THREAD_INFO_IN_TASK, core code maintains
thread_info::cpu, and low-level architecture code can access this to
build raw_smp_processor_id(). With CONFIG_THREAD_INFO_IN_TASK, core code
maintains task_struct::cpu, which for reasons of hte header soup is not
accessible to low-level arch code.

Instead, we can maintain a percpu variable containing the cpu number.

For both the old and new implementation of raw_smp_processor_id(), we
read a syreg into a GPR, add an offset, and load the result. As the
offset is now larger, it may not be folded into the load, but otherwise
the assembly shouldn't change much.

580efaa7cc arm64: smp: prepare for smp_processor_id() rework
Subsequent patches will make smp_processor_id() use a percpu variable.
This will make smp_processor_id() dependent on the percpu offset, and
thus we cannot use smp_processor_id() to figure out what to initialise
the offset to.

Prepare for this by initialising the percpu offset based on
current::cpu, which will work regardless of how smp_processor_id() is
implemented. Also, make this relationship obvious by placing this code
together at the start of secondary_start_kernel().

623b476fc8 arm64: move sp_el0 and tpidr_el1 into cpu_suspend_ctx
When returning from idle, we rely on the fact that thread_info lives at
the end of the kernel stack, and restore this by masking the saved stack
pointer. Subsequent patches will sever the relationship between the
stack and thread_info, and to cater for this we must save/restore sp_el0
explicitly, storing it in cpu_suspend_ctx.

As cpu_suspend_ctx must be doubleword aligned, this leaves us with an
extra slot in cpu_suspend_ctx. We can use this to save/restore tpidr_el1
in the same way, which simplifies the code, avoiding pointer chasing on
the restore path (as we no longer need to load thread_info::cpu followed
by the relevant slot in __per_cpu_offset based on this).

This patch stashes both registers in cpu_suspend_ctx.

9bbd4c56b0 arm64: prep stack walkers for THREAD_INFO_IN_TASK
When CONFIG_THREAD_INFO_IN_TASK is selected, task stacks may be freed
before a task is destroyed. To account for this, the stacks are
refcounted, and when manipulating the stack of another task, it is
necessary to get/put the stack to ensure it isn't freed and/or re-used
while we do so.

This patch reworks the arm64 stack walking code to account for this.
When CONFIG_THREAD_INFO_IN_TASK is not selected these perform no
refcounting, and this should only be a structural change that does not
affect behaviour.

The walk_stackframe functions is architecture-specific, with a varying
prototype, and common code should not use it directly. None of its
current users can be built as modules. With THREAD_INFO_IN_TASK, users

876e7a38e8 arm64: traps: simplify die() and __die()
In arm64's die and __die routines we pass around a thread_info, and
subsequently use this to determine the relevant task_struct, and the end
of the thread's stack. Subsequent patches will decouple thread_info from
the stack, and this approach will no longer work.

To figure out the end of the stack, we can use the new generic
end_of_stack() helper. As we only call __die() from die(), and die()
always deals with the current task, we can remove the parameter and have
both acquire current directly, which also makes it clear that __die
can't be called for arbitrary tasks.

dcbe02855f arm64: thread_info remove stale items
We have a comment claiming __switch_to() cares about where cpu_context
is located relative to cpu_domain in thread_info. However arm64 has
never had a thread_info::cpu_domain field, and neither __switch_to nor
cpu_switch_to care where the cpu_context field is relative to others.

Additionally, the init_thread_info alias is never used anywhere in the
kernel, and will shortly become problematic when thread_info is moved
into task_struct.

This patch removes both.

5c99bfdc1f arm64: dts: apq8016-sbc: Set up LDO2, LDO6 and LDO17 regulator voltage ranges
On the APQ8016 SBC, the LDO2 PM8916 regulator feeds 1.2V to the following:

- VDDA_1P2_MIPI_DSI and VDDA_MIPI_CSI pins on APQ8016.
- VCCCAD pins on the LPDDR3 chip.
- VDDPX_1 pins on APQ8016.

The LDO6 regulator feeds 1.8V to:
- VDAA_MIPI_DSI0_PLL pin on APQ8016.
- QFPROM_BLOW_VDD pin on PM8916.
- The AVDD, A2VDD and DVDD pins on ADV7533 bridge.

The LDO17 regulator feeds 3.3V to:
- The V3P3 pin on ADV7533 bridge.

Currently, the regulator min/max voltages for all the LDOs are set to the
range of what the PMIC supports. Set the ranges for L2, L6 and L17 to what
we need, i.e. 1.2V, 1.8V and 3.3V respectively.

094339443e arm64: percpu: kill off final ACCESS_ONCE() uses
For several reasons it is preferable to use {READ,WRITE}_ONCE() rather than
ACCESS_ONCE(). For example, these handle aggregate types, result in shorter
source code, and better document the intended access (which may be useful for
instrumentation features such as the upcoming KTSAN).

Over a number of patches, most uses of ACCESS_ONCE() in arch/arm64 have been
migrated to {READ,WRITE}_ONCE(). For consistency, and the above reasons, this
patch migrates the final remaining uses.

20156ce236 arm64: hugetlb: remove the wrong pmd check in find_num_contig()
The find_num_contig() will return 1 when the pmd is not present.
It will cause a kernel dead loop in the following scenaro:

   1.) pmd entry is not present.

   2.) the page fault occurs:
       ... hugetlb_fault() --> hugetlb_no_page() --> set_huge_pte_at()

   3.) set_huge_pte_at() will only set the first PMD entry, since the
       find_num_contig just return 1 in this case. So the PMD entries
       are all empty except the first one.

   4.) when kernel accesses the address mapped by the second PMD entry,
       a new page fault occurs:
       ... hugetlb_fault() --> huge_ptep_set_access_flags()

       The second PMD entry is still empty now.

   5.) When the kernel returns, the access will cause a page fault again.
       The kernel will run like the "4)" above.
       We will see a dead loop since here.

The dead loop is caught in the 32M hugetlb page (2M PMD + Contiguous bit).

This patch removes wrong pmd check, and fixes this dead loop.

This patch also removes the redundant checks for PGD/PUD in
the find_num_contig().

8d897006fe arm64: dts: marvell: add unique identifiers for Armada A8k SPI controllers
Enabling SPI controllers, which are attached to different busses
inside an SoC, may result in overlapping enumeration and cause
sysfs registration failure. Example log after enabling two
controllers on Armada 8040 SoC with same identifiers:

[    3.740415] sysfs: cannot create duplicate filename
'/class/spi_master/spi0'
[    3.747510] ------------[ cut here ]------------
[    3.752145] WARNING: at fs/sysfs/dir.c:31
[...]
[    4.002299] orion_spi: probe of f4700600.spi failed with error -17

spi-orion driver offers dedicated DT property ('cell-index'), that
allow setting unique identifiers. Recently added support for CP110-slave
HW block introduced two new SPI controllers' nodes with same ID as
ones from CP110-master.

This commit fixes the issue by assigning different 'cell-index' values
for CP110-slave SPI controllers.
