908001d778 arm64: dts: renesas: salvator-common: Add ADV7482 support
The Salvator boards use an ADV7482 receiver for HDMI and CVBS inputs.

Provide ADV7482 node on the i2c4 bus, along with connectors for the
hdmi and cvbs inputs, and link to the csi20 and csi40 nodes as outputs.

159fd7b8d3 arm64/sve: Write ZCR_EL1 on context switch only if changed
Writes to ZCR_EL1 are self-synchronising, and so may be expensive
in typical implementations.

This patch adopts the approach used for costly system register
writes elsewhere in the kernel: the system register write is
suppressed if it would not change the stored value.

Since the common case will be that of switching between tasks that
use the same vector length as one another, prediction hit rates on
the conditional branch should be reasonably good, with lower
expected amortised cost than the unconditional execution of a
heavyweight self-synchronising instruction.

37c3ec2d81 arm64: topology: divorce MC scheduling domain from core_siblings
Now that we have an accurate view of the physical topology
we need to represent it correctly to the scheduler. Generally MC
should equal the LLC in the system, but there are a number of
special cases that need to be dealt with.

In the case of NUMA in socket, we need to assure that the sched
domain we build for the MC layer isn't larger than the DIE above it.
Similarly for LLC's that might exist in cross socket interconnect or
directory hardware we need to assure that MC is shrunk to the socket
or NUMA node.

This patch builds a sibling mask for the LLC, and then picks the
smallest of LLC, socket siblings, or NUMA node siblings, which
gives us the behavior described above. This is ever so slightly
different than the similar alternative where we look for a cache
layer less than or equal to the socket/NUMA siblings.

The logic to pick the MC layer affects all arm64 machines, but
only changes the behavior for DT/MPIDR systems if the NUMA domain
is smaller than the core siblings (generally set to the cluster).
Potentially this fixes a possible bug in DT systems, but really
it only affects ACPI systems where the core siblings is correctly
set to the socket siblings. Thus all currently available ACPI
systems should have MC equal to LLC, including the NUMA in socket
machines where the LLC is partitioned between the NUMA nodes.

2f0a5d107e arm64: topology: enable ACPI/PPTT based CPU topology
Propagate the topology information from the PPTT tree to the
cpu_topology array. We can get the thread id and core_id by assuming
certain levels of the PPTT tree correspond to those concepts.
The package_id is flagged in the tree and can be found by calling
find_acpi_cpu_topology_package() which terminates
its search when it finds an ACPI node flagged as the physical
package. If the tree doesn't contain enough levels to represent
all of the requested levels then the root node will be returned
for all subsequent levels.

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-05-17

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Provide a new BPF helper for doing a FIB and neighbor lookup
   in the kernel tables from an XDP or tc BPF program. The helper
   provides a fast-path for forwarding packets. The API supports
   IPv4, IPv6 and MPLS protocols, but currently IPv4 and IPv6 are
   implemented in this initial work, from David (Ahern).

2) Just a tiny diff but huge feature enabled for nfp driver by
   extending the BPF offload beyond a pure host processing offload.
   Offloaded XDP programs are allowed to set the RX queue index and
   thus opening the door for defining a fully programmable RSS/n-tuple
   filter replacement. Once BPF decided on a queue already, the device
   data-path will skip the conventional RSS processing completely,
   from Jakub.

3) The original sockmap implementation was array based similar to
   devmap. However unlike devmap where an ifindex has a 1:1 mapping
   into the map there are use cases with sockets that need to be
   referenced using longer keys. Hence, sockhash map is added reusing
   as much of the sockmap code as possible, from John.

4) Introduce BTF ID. The ID is allocatd through an IDR similar as
   with BPF maps and progs. It also makes BTF accessible to user
   space via BPF_BTF_GET_FD_BY_ID and adds exposure of the BTF data
   through BPF_OBJ_GET_INFO_BY_FD, from Martin.

5) Enable BPF stackmap with build_id also in NMI context. Due to the
   up_read() of current->mm->mmap_sem build_id cannot be parsed.
   This work defers the up_read() via a per-cpu irq_work so that
   at least limited support can be enabled, from Song.

6) Various BPF JIT follow-up cleanups and fixups after the LD_ABS/LD_IND
   JIT conversion as well as implementation of an optimized 32/64 bit
   immediate load in the arm64 JIT that allows to reduce the number of
   emitted instructions; in case of tested real-world programs they
   were shrinking by three percent, from Daniel.

7) Add ifindex parameter to the libbpf loader in order to enable
   BPF offload support. Right now only iproute2 can load offloaded
   BPF and this will also enable libbpf for direct integration into
   other applications, from David (Beckett).

8) Convert the plain text documentation under Documentation/bpf/ into
   RST format since this is the appropriate standard the kernel is
   moving to for all documentation. Also add an overview README.rst,
   from Jesper.

9) Add __printf verification attribute to the bpf_verifier_vlog()
   helper. Though it uses va_list we can still allow gcc to check
   the format string, from Mathieu.

10) Fix a bash reference in the BPF selftest's Makefile. The '|& ...'
    is a bash 4.0+ feature which is not guaranteed to be available
    when calling out to shell, therefore use a more portable variant,
    from Joe.

11) Fix a 64 bit division in xdp_umem_reg() by using div_u64()
    instead of relying on the gcc built-in, from Björn.

12) Fix a sock hashmap kmalloc warning reported by syzbot when an
    overly large key size is used in hashmap then causing overflows
    in htab->elem_size. Reject bogus attr->key_size early in the
    sock_hash_alloc(), from Yonghong.

13) Ensure in BPF selftests when urandom_read is being linked that
    --build-id is always enabled so that test_stacktrace_build_id[_nmi]
    won't be failing, from Alexei.

14) Add bitsperlong.h as well as errno.h uapi headers into the tools
    header infrastructure which point to one of the arch specific
    uapi headers. This was needed in order to fix a build error on
    some systems for the BPF selftests, from Sirio.

15) Allow for short options to be used in the xdp_monitor BPF sample
    code. And also a bpf.h tools uapi header sync in order to fix a
    selftest build failure. Both from Prashant.

16) More formally clarify the meaning of ID in the direct packet access
    section of the BPF documentation, from Wang.

When waiting for a cacheline to change state in cmpwait, we may immediately
wake-up the first time around the outer loop if the event register was

Avoid these spurious wakeups by explicitly clearing the event register

e75bef2a4f arm64: Select ARCH_HAS_FAST_MULTIPLIER
It is probably safe to assume that all Armv8-A implementations have a
multiplier whose efficiency is comparable or better than a sequence of
three or so register-dependent arithmetic instructions. Select
ARCH_HAS_FAST_MULTIPLIER to get ever-so-slightly nicer codegen in the
few dusty old corners which care.

In a contrived benchmark calling hweight64() in a loop, this does indeed
turn out to be a small win overall, with no measurable impact on
Cortex-A57 but about 5% performance improvement on Cortex-A53.

52d2e0cec7 arm64: dts: renesas: r8a77980: disable EtherAVB
When adding the R8A77980 EtherAVB device I failed to notice that it does
not have the usual "status" property disabling the described devices in
anticipation that the board device trees enable the devices according to
their needs. This causes the EtherAVB driver to successfully probe despite
e.g. the needed pins not having been configured -- luckily, "eth<n>" device
can't be opened anyway...

06a574c7ef arm64: dts: renesas: salvator-common: use audio-graph-card for Sound
Current Sound is using simple-audio-card which can't support HDMI.
To use HDMI sound, we need to use audio-graph-card.
But, one note is that r8a7795 has 2 HDMI ports, but r8a7796 has 1.
Because of this mismatch, supporting HDMI on salvator-common is
impossible.
Thus, this patch exchange sound card to audio-graph-card and keep
supporting ak4613 as 1st sound node.
r8a7795/r8a7796 salvator-x{s} need to add HDMI sound individually.

This patch increases the ARCH_DMA_MINALIGN to 128 so that it covers the
currently known Cache Writeback Granule (CTR_EL0.CWG) on arm64 and moves
the fallback in cache_line_size() from L1_CACHE_BYTES to this constant.
In addition, it warns (and taints) if the CWG is larger than
ARCH_DMA_MINALIGN as this is not safe with non-coherent DMA.

bf308242ab KVM: arm/arm64: VGIC/ITS: protect kvm_read_guest() calls with SRCU lock
kvm_read_guest() will eventually look up in kvm_memslots(), which requires
either to hold the kvm->slots_lock or to be inside a kvm->srcu critical
section.
In contrast to x86 and s390 we don't take the SRCU lock on every guest
exit, so we have to do it individually for each kvm_read_guest() call.

Provide a wrapper which does that and use that everywhere.

Note that ending the SRCU critical section before returning from the
kvm_read_guest() wrapper is safe, because the data has been *copied*, so
we don't need to rely on valid references to the memslot anymore.

c6f5d02b6a locking/spinlocks/arm64: Remove smp_mb() from arch_spin_is_locked()
The following commit:

  38b850a730 ("arm64: spinlock: order spin_{is_locked,unlock_wait} against local locks")

... added an smp_mb() to arch_spin_is_locked(), in order
"to ensure that the lock value is always loaded after any other locks have
been taken by the current CPU", and reported one example (the "insane case"
in ipc/sem.c) relying on such guarantee.

It is however understood that spin_is_locked() is not required to provide
such an ordering guarantee (a guarantee that is currently not provided by
all the implementations/archs), and that callers relying on such ordering
should instead insert suitable memory barriers before acting on the result
of spin_is_locked().

Following a recent auditing [1] of the callers of {,raw_}spin_is_locked(),
revealing that none of them are relying on the ordering guarantee anymore,
this commit removes the leading smp_mb() from the primitive thus reverting
38b850a730.

We can trivially save 4 bytes in prologue for cBPF since tail calls

here, x25 (fp) and x26 (tcc), so no point in changing that, only

6d2eea6fb0 bpf, arm64: optimize 32/64 immediate emission
Improve the JIT to emit 64 and 32 bit immediates, the current
algorithm is not optimal and we often emit more instructions
than actually needed. arm64 has movz, movn, movk variants but
for the current 64 bit immediates we only use movz with a
series of movk when needed.

For example loading ffffffffffffabab emits the following 4
instructions in the JIT today:

  * movz: abab, shift:  0, result: 000000000000abab
  * movk: ffff, shift: 16, result: 00000000ffffabab
  * movk: ffff, shift: 32, result: 0000ffffffffabab
  * movk: ffff, shift: 48, result: ffffffffffffabab

Whereas after the patch the same load only needs a single
instruction:

  * movn: 5454, shift:  0, result: ffffffffffffabab

Another example where two extra instructions can be saved:

  * movz: abab, shift:  0, result: 000000000000abab
  * movk: 1f2f, shift: 16, result: 000000001f2fabab
  * movk: ffff, shift: 32, result: 0000ffff1f2fabab
  * movk: ffff, shift: 48, result: ffffffff1f2fabab

After the patch:

  * movn: e0d0, shift: 16, result: ffffffff1f2fffff
  * movk: abab, shift:  0, result: ffffffff1f2fabab

Another example with movz, before:

  * movz: 0000, shift:  0, result: 0000000000000000
  * movk: fea0, shift: 32, result: 0000fea000000000

After:

  * movz: fea0, shift: 32, result: 0000fea000000000

Moreover, reuse emit_a64_mov_i() for 32 bit immediates that
are loaded via emit_a64_mov_i64() which is a similar optimization
as done in 6fe8b9c1f4 ("bpf, x64: save several bytes by using
mov over movabsq when possible"). On arm64, the latter allows to
use a single instruction with movn due to zero extension where
otherwise two would be needed. And last but not least add a
missing optimization in emit_a64_mov_i() where movn is used but
the subsequent movk not needed. With some of the Cilium programs
in use, this shrinks the needed instructions by about three
percent. Tested on Cavium ThunderX CN8890.

   more standard SPDX tag and dual GPL 2.0 and MIT. This is a follow-up
   to this discussion with Greg:
   https://lkml.org/lkml/2018/4/28/179
 
 - Dan adds support for two Luxul devices: XAP-1610 (based on BCM47094)
   and XWR-3150 V1 (similar to XWR-3100)
 
 - Stefan provides a set of updates to the BCM283x Device Tree sources to
   support the Raspberry Pi 3 B+ for both the ARM and ARM64 kernels. He
   adds the required nodes for the LAN7515 USB Ethernet, Cypress CYW43455
   BT/WiFi combo chip. Stefan also provides a few fixes for the PWM pin
   assignment for RPi 3B and Zero/Zero W. Finally, Stefan adds the
   missing GPIOs for controlling additional peripherals now that support
   for the RPi 3 GPIO expander has landed

The bpf syscall and selftests conflicts were trivial
overlapping changes.

The r8169 change involved moving the added mdelay from 'net' into a

A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts.  I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf

d93277b983 Revert "arm64: Increase the max granular size"
This reverts commit 9730348075.

Commit 9730348075 ("arm64: Increase the max granular size") increased
the cache line size to 128 to match Cavium ThunderX, apparently for some
performance benefit which could not be confirmed. This change, however,
has an impact on the network packet allocation in certain circumstances,
requiring slightly over a 4K page with a significant performance
degradation. The patch reverts L1_CACHE_SHIFT back to 6 (64-byte cache
line).

349b0f95e1 arm64: dts: juno/rtsm: re-structure motherboard includes
It is a bit unorthodox to just include a file in the middle of a another
DTS file, it breaks the pattern from other device trees and also makes
it really hard to reference things across the files with phandles.

Restructure the include for the Juno/RTSM motherboards to happen at the
top of the file, reference the target nodes directly, and indent the
motherboard .dtsi files to reflect their actual depth in the hierarchy.

This is a purely syntactic change that result in the same DTB files from
the DTS/DTSI files. This is based on similar patch from Linus Walleij
for ARM Vexpress platforms.

09230cbc1b swiotlb: move the SWIOTLB config symbol to lib/Kconfig
This way we have one central definition of it, and user can select it as
needed.  The new option is not user visible, which is the behavior
it had in most architectures, with a few notable exceptions:

 - On x86_64 and mips/loongson3 it used to be user selectable, but
   defaulted to y.  It now is unconditional, which seems like the right
   thing for 64-bit architectures without guaranteed availablity of
   IOMMUs.
 - on powerpc the symbol is user selectable and defaults to n, but
   many boards select it.  This change assumes no working setup
   required a manual selection, but if that turned out to be wrong
   we'll have to add another select statement or two for the respective
   boards.

15b28bbcd5 dma-debug: move initialization to common code
Most mainstream architectures are using 65536 entries, so lets stick to
that.  If someone is really desperate to override it that can still be
done through <asm/dma-mapping.h>, but I'd rather see a really good
rationale for that.

dma_debug_init is now called as a core_initcall, which for many
architectures means much earlier, and provides dma-debug functionality
earlier in the boot process.  This should be safe as it only relies
on the memory allocator already being available.

b220244d41 arm64: vgic-v2: Fix proxying of cpuif access
Proxying the cpuif accesses at EL2 makes use of vcpu_data_guest_to_host
and co, which check the endianness, which call into vcpu_read_sys_reg...
which isn't mapped at EL2 (it was inlined before, and got moved OoL
with the VHE optimizations).

The result is of course a nice panic. Let's add some specialized
cruft to keep the broken platforms that require this hack alive.

But, this code used vcpu_data_guest_to_host(), which expected us to
write the value to host memory, instead we have trapped the guest's
read or write to an mmio-device, and are about to replay it using the
host's readl()/writel() which also perform swabbing based on the host
endianness. This goes wrong when both host and guest are big-endian,
as readl()/writel() will undo the guest's swabbing, causing the
big-endian value to be written to device-memory.

What needs doing?
A big-endian guest will have pre-swabbed data before storing, undo this.
If its necessary for the host, writel() will re-swab it.

For a read a big-endian guest expects to swab the data after the load.
The hosts's readl() will correct for host endianness, giving us the
device-memory's value in the register. For a big-endian guest, swab it
as if we'd only done the load.

For a little-endian guest, nothing needs doing as readl()/writel() leave
the correct device-memory value in registers.

Tested on Juno with that rarest of things: a big-endian 64K host.
Based on a patch from Marc Zyngier.

A typo in kvm_vcpu_set_be()'s call:

causes us to use the 32bit register value as an index into the sys_reg[]
array, and sail off the end of the linear map when we try to bring up
big-endian secondaries.

3789c122d0 arm64: avoid instrumenting atomic_ll_sc.o
Our out-of-line atomics are built with a special calling convention,
preventing pointless stack spilling, and allowing us to patch call sites
with ARMv8.1 atomic instructions.

Instrumentation inserted by the compiler may result in calls to
functions not following this special calling convention, resulting in
registers being unexpectedly clobbered, and various problems resulting
from this.

For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the
compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of
the atomic functions. This has been observed to result in spurious
cmpxchg failures, leading to a hang early on in the boot process.

This patch avoids such issues by preventing instrumentation of our
out-of-line atomics.

Heiko Stübner justified pretty well the change in commit e330eb86ba
("ARM: multi_v7_defconfig: enable Rockchip io-domain driver"). This
change is also needed for arm64 rockchip boards, so, do the same for arm64.

The io-domain driver is necessary to notify the soc about voltages
changes happening on supplying regulators. Probably the most important
user right now is the mmc tuning code, where the soc needs to get
notified when the voltage is dropped to the 1.8V point.

As this option is necessary to successfully tune UHS cards etc, it
should get built in. Otherwise, tuning will fail with,

   dwmmc_rockchip fe320000.dwmmc: All phases bad!
   mmc0: tuning execution failed: -5

3eb0f5193b signal: Ensure every siginfo we send has all bits initialized
Call clear_siginfo to ensure every stack allocated siginfo is properly
initialized before being passed to the signal sending functions.

Note: It is not safe to depend on C initializers to initialize struct
siginfo on the stack because C is allowed to skip holes when
initializing a structure.

The initialization of struct siginfo in tracehook_report_syscall_exit
was moved from the helper user_single_step_siginfo into
tracehook_report_syscall_exit itself, to make it clear that the local
variable siginfo gets fully initialized.

In a few cases the scope of struct siginfo has been reduced to make it
clear that siginfo siginfo is not used on other paths in the function
in which it is declared.

Instances of using memset to initialize siginfo have been replaced
with calls clear_siginfo for clarity.

arm64: dts: allwinner: Add dts file for Libre Computer Board ALL-H3-CC H5 ver.
The Libre Computer Board ALL-H3-CC from Libre Technology is a Raspberry
Pi B+ form factor single board computer based on the Allwinner H2+, H3,
or H5 SoCs with the same PCB.
The board has 2GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes
and connectors are in the exact same position as on the Raspberry Pi B+.

This patch enables the H5 variant using the H3 board definition moved to
a common dtsi in an earlier patch. The dts simply include the common dtsi
and declares the correct compatible and model of the H5 variant.

Commit fb8722735f ("arm64: support __int128 on gcc 5+") added support
for arm64 __int128 with gcc with a version-conditional, but neglected to
enable this for clang, which in fact appears to support aarch64 __int128.
This commit therefore enables it if the compiler is clang, using the
same type of makefile conditional used elsewhere in the tree.

9478f1927e arm64: only advance singlestep for user instruction traps
Our arm64_skip_faulting_instruction() helper advances the userspace
singlestep state machine, but this is also called by the kernel BRK
handler, as used for WARN*().

Thus, if we happen to hit a WARN*() while the user singlestep state
machine is in the active-no-pending state, we'll advance to the
active-pending state without having executed a user instruction, and
will take a step exception earlier than expected when we return to
userspace.

Let's fix this by only advancing the state machine when skipping a user
instruction.

ed231ae384 arm64/kernel: rename module_emit_adrp_veneer->module_emit_veneer_for_adrp
Commit a257e02579 ("arm64/kernel: don't ban ADRP to work around
Cortex-A53 erratum #843419") introduced a function whose name ends with
"_veneer".

This clashes with commit bd8b22d288 ("Kbuild: kallsyms: ignore veneers
emitted by the ARM linker"), which removes symbols ending in "_veneer"
from kallsyms.

The problem was manifested as 'perf test -vvvvv vmlinux' failed,
correctly claiming the symbol 'module_emit_adrp_veneer' was present in
vmlinux, but not in kallsyms.

...
    ERR : 0xffff00000809aa58: module_emit_adrp_veneer not on kallsyms
...
    test child finished with -1
    ---- end ----
    vmlinux symtab matches kallsyms: FAILED!

Fix the problem by renaming module_emit_adrp_veneer to
module_emit_veneer_for_adrp.  Now the test passes.

71c751f2a4 arm64: add sentinel to kpti_safe_list
We're missing a sentinel entry in kpti_safe_list. Thus is_midr_in_range_list()
can walk past the end of kpti_safe_list. Depending on the contents of memory,
this could erroneously match a CPU's MIDR, cause a data abort, or other bad
outcomes.

Add the sentinel entry to avoid this.

85bd0ba1ff arm/arm64: KVM: Add PSCI version selection API
Although we've implemented PSCI 0.1, 0.2 and 1.0, we expose either 0.1
or 1.0 to a guest, defaulting to the latest version of the PSCI
implementation that is compatible with the requested version. This is
no different from doing a firmware upgrade on KVM.

But in order to give a chance to hypothetical badly implemented guests
that would have a fit by discovering something other than PSCI 0.2,
let's provide a new API that allows userspace to pick one particular
version of the API.

This is implemented as a new class of "firmware" registers, where
we expose the PSCI version. This allows the PSCI version to be
save/restored as part of a guest migration, and also set to
any supported version if the guest requires it.

83335eb4f6 y2038: arm64: Extend sysvipc compat data structures
Both 32-bit amd 64-bit ARM use the asm-generic header files for their
sysvipc data structures, so no special care is needed to make those
work beyond y2038, with the one exception of compat mode: Since there
is no asm-generic definition of the compat mode IPC structures, ARM64
provides its own copy, and we make those match the changes in the native
asm-generic header files.

There is sufficient padding in these data structures to extend all
timestamps to 64 bit, but on big-endian ARM kernels, the padding
is in the wrong place, so the C library has to ensure it reassembles
a 64-bit time_t correctly.

57ee976747 ARM64: dts: meson-gx: fix gxl clock controller compatible
There are a few differences between the gxbb and gxl clock controllers
which makes them incompatible. The hdmi, gp0 and fixed pll are
different. The rate of these plls reported by gxbb driver on a gxl
device would be wrong.

Remove the gxbb compatible from the gxl clock controller node so only
the correct driver is matched.

Like the meson-gx, the axg clock controller should go through a syscon
to access the hhi register region, and not directly map the region.
This way, the hhi register region can be used safely by multiple drivers.

0d55303c51 compat: Move compat_timespec/ timeval to compat_time.h
All the current architecture specific defines for these
are the same. Refactor these common defines to a common
header file.

The new common linux/compat_time.h is also useful as it
will eventually be used to hold all the defines that
are needed for compat time types that support non y2038
safe types. New architectures need not have to define these
new types as they will only use new y2038 safe syscalls.
This file can be deleted after y2038 when we stop supporting
non y2038 safe syscalls.

The patch also requires an operation similar to:

git grep "asm/compat\.h" | cut -d ":" -f 1 |  xargs -n 1 sed -i -e "s%asm/compat.h%linux/compat.h%g"
