Pull arm64 fixes from Catalin Marinas:
- Update the linker script to use L1_CACHE_BYTES instead of hard-coded
64. We recently changed L1_CACHE_BYTES to 128
- Improve race condition reporting on set_pte_at() and change the BUG
to WARN_ONCE. With hardware update of the accessed/dirty state, we
need to ensure that set_pte_at() does not inadvertently override
hardware updated state. The patch also makes the checks ignore
!pte_valid() new entries

Currently the BUG_ON() checks do not give enough information about the
PTEs being set. This patch changes BUG_ON to WARN_ONCE and dumps the
values of the old and new PTEs. In addition, the checks are only made if
the new PTE entry is valid.

When restarting a syscall with regs->ax == -ERESTART_RESTARTBLOCK,
regs->ax is assigned to a restart_syscall number. For x32 tasks, this
syscall number must have __X32_SYSCALL_BIT set, otherwise it will be
an x86_64 syscall number instead of a valid x32 syscall number. This
issue has been there since the introduction of x32.

MPX decodes instructions in order to tell which bounds register
was violated. Part of this decoding involves looking at the "REX
prefix" which is a special instrucion prefix used to retrofit
support for new registers in to old instructions.
The X86_REX_*() macros are defined to return actual bit values:
#define X86_REX_R(rex) ((rex) & 4)
*not* boolean values. However, the MPX code was checking for
them like they were booleans. This might have led to us
mis-decoding the "REX prefix" and giving false information out to
userspace about bounds violations. X86_REX_B() actually is bit 1,
so this is really only broken for the X86_REX_X() case.
Fix the conditionals up to tolerate the non-boolean values.

- Remove a piece of code in the generic power domains framework that

- Reduce the log level of a PCI PM message that generates a lot of
false-positive log noise for some drivers and improve the message
itself while at it (Imre Deak).
- Fix the OF-based domain lookup code in the generic power domains
framework to make it drop references to DT nodes correctly (Eric
Anholt).
- Prevent the cpufreq core from setting the policy back to the
default after a CPU offline/online cycle for cpufreq drivers

- Fix a build problem for CONFIG_ACPI unset in the device properties
framework (Hanjun Guo).

Commit e6fab5442345 ("ARM/arm64: KVM: test properly for a PTE's
uncachedness") modified the logic to test whether a HYP or stage-2
mapping needs flushing, from [incorrectly] interpreting the page table
attributes to [incorrectly] checking whether the PFN that backs the
mapping is covered by host system RAM. The PFN number is part of the
output of the translation, not the input, so we have to use pte_pfn()
on the contents of the PTE, not __phys_to_pfn() on the HYP virtual
address or stage-2 intermediate physical address.

System register accesses also use zero register for Rt == 31, and
therefore using it will also result in getting SP value instead. This
patch makes them also using new accessors, introduced by the previous
patch. Since register value is no longer directly associated with storage
inside vCPU context structure, we introduce a dedicated storage for it in
struct sys_reg_params.
This refactor also gets rid of "massive hack" in kvm_handle_cp_64().

On ARM64 register index of 31 corresponds to both zero register and SP.
However, all memory access instructions, use ZR as transfer register. SP
is used only as a base register in indirect memory addressing, or by
register-register arithmetics, which cannot be trapped here.
Correct emulation is achieved by introducing new register accessor
functions, which can do special handling for reg_num == 31. These new
accessors intentionally do not rely on old vcpu_reg() on ARM64, because
it is to be removed. Since the affected code is shared by both ARM
flavours, implementations of these accessors are also added to ARM32 code.
This patch fixes setting MMIO register to a random value (actually SP)
instead of zero by something like:
*((volatile int *)reg) = 0;
compilers tend to generate "str wzr, [xx]" here

The problem is in pmd_pfn_mask() and pmd_flags_mask(). These
helpers use PMD_PAGE_MASK to calculate resulting mask.
PMD_PAGE_MASK is 'unsigned long', not 'unsigned long long' as
phys_addr_t is on 32-bit PAE (ARCH_PHYS_ADDR_T_64BIT). As a
result, the upper bits of resulting mask get truncated.
pud_pfn_mask() and pud_flags_mask() aren't problematic since we
don't have PUD page table level on 32-bit systems, but it's
reasonable to keep them consistent with PMD counterpart.
Introduce PHYSICAL_PMD_PAGE_MASK and PHYSICAL_PUD_PAGE_MASK in
addition to existing PHYSICAL_PAGE_MASK and reworks helpers to
use them.

Commit 4d6b4e69a245 ("x86/PCI/ACPI: Use common interface to support
PCI host bridge") converted x86 to use the common interface
acpi_pci_root_create, but the conversion missed on code piece in
arch/x86/pci/bus_numa.c, which causes regression on some legacy
AMD platforms as reported by Arthur Marsh <arthur.marsh@internode.on.net>.
The root causes is that acpi_pci_root_create() fails to insert
host bridge resources into iomem_resource/ioport_resource because
x86_pci_root_bus_resources() has already inserted those resources.
So change x86_pci_root_bus_resources() to not insert resources into
iomem_resource/ioport_resource.

If there are no persistent memory ranges present then don't bother
creating the platform device. Otherwise, it loads the full libnvdimm
sub-system only to discover no resources present.

On the ARM architecture, individual platforms select CONFIG_USE_OF if they
need it, but all device tree code is keyed off CONFIG_OF. When building
a platform without DT support and manually enabling CONFIG_OF, we now
get a number of build errors, e.g.
arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
We could now try to separate the use case of booting from DT vs. the
case of using the dynamic implementation, but that seems more complicated
than it can gain us.
This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
extra code when we just want the dynamic OF implementation, but that seems
like a rather obscure case, and this version solves all CONFIG_OF related
randconfig regressions.

Pull ARM SoC fixes from Arnd Bergmann:
"There is a small backlog of at91 patches here, the most significant is
the addition of some sama5d2 Xplained nodes that were waiting on an
MFD include file to get merged through another tree.
We normally try to sort those out before the merge window opens, but
the maintainer wasn't aware of that here and I decided to merge the
changes this time as an exception.
On OMAP a series of audio changes for dra7 missed the merge window but
turned out to be necessary to fix a boot time imprecise external abort
error and to get audio working.
The other changes are the usual simple changes, here is a list sorted
by platform:
at91:
removal of a useless defconfig option
removal of some legacy DT pieces
use of the proper watchdog compatible string
update of the MAINTAINERS entries for some Atmel drivers
drivers/scpi:
hide get_scpi_ops in module from built-in code
imx:
add missing .irq_set_type for i.MX GPC irq_chip.
fix the wrong spi-num-chipselects settings for Vybrid DSPI devices.
fix a merge error in Vybrid dts regarding to ADC device property
keystone:
fix the optional PDSP firmware loading
fix linking RAM setup for QMs

mvebu:
fix QNAP TS219 power-off in dts
fix legacy get_irqnr_and_base for dove and orion5x
omap:
fix l4 related boot time errors for dm81xx
use lockless cldm/pwrdm api in omap4_boot_secondary
remove t410 abort handler to avoid hiding other critical errors
mark cpuidle tracepoints as _rcuidle
fix module alias for omap-ocp2scp

mapping run-time regions
- Fix CPUID register extraction of unsigned fields (not to be
sign-extended)
- ASID allocator fix to deal with long-running tasks over multiple
generation roll-overs
- Revert support for marking page ranges as contiguous PTEs (it leads
to TLB conflicts and requires additional non-trivial kernel changes)
- Proper early_alloc() failure check

larger than the KASan shadow memory)

engineering spec)
