arm64: dts: Fix broken architected timer interrupt trigger
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).
A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.
The respective maintainers are of course welcome to prove me wrong.
While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

The current implementation only works if the da9xxx devices are added

both devices. Otherwise, the driver for the first device gets probed

fails when using the IP core switcher or when having the i2c master
driver as a module.
So, we need to disable both da9xxx once we detected one of them. We now
use i2c_transfer with hardcoded i2c_messages and device addresses, so we
don't need the da9xxx client devices to be instantiated. Because the
fixup is used on specific boards only, the addresses are not going to

To avoid this, implement pmu_{enable,disable} callbacks to stop and

are now stopped, we cannot poll the cycle counter to wait for events to
drain from the bus. However, as the counters are stopped and the events

ARM: tegra: Correct polarity for Tegra114 PMIC interrupt
The ARM GIC only supports interrupts with either level-high or
rising-edge types for SPIs. The interrupt type for the Palmas PMIC used
for Tegra114 boards is specified as level-low which is invalid for the
GIC. This has gone undetected because until recently, failures to set
the interrupt type when the interrupts are mapped via firmware (such as
device-tree) have not been reported. Since commits
4b357daed698
("genirq: Look-up trigger type if not specified by caller") and
1e2a7d78499e ("irqdomain: Don't set type when mapping an IRQ"), failure
to set the interrupt type will cause the requesting of the interrupt to
fail and exposing incorrectly configured interrupts.
Please note that although the interrupt type was never being set for the
Palmas PMIC, it was still working fine, because the default type setting
for the interrupt, 'level-high', happen to match the correct type for
the interrupt.
Finally, it should be noted that the Palmas interrupt from the PMIC is
actually 'level-low', however, this interrupt signal is inverted by the
Tegra PMC and so the GIC actually sees a 'level-high' interrupt which is
what should be specified in the device-tree interrupt specifier.

EDAC, skx_edac: Add EDAC driver for Skylake
This is an entirely new driver instead of yet another set of patches
to sb_edac.c because:
1) Mapping from PCI devices to socket/memory controller is significantly
different. Skylake scatters devices on a socket across a number of
PCI buses.
2) There is an extra level of interleaving via the "mcroute" register
that would be a little messy to squeeze into the old driver.
3) Validation is getting too expensive. Changes to sb_edac need to
be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and
Knights Landing.

parisc: Fix order of EREFUSED define in errno.h
When building gccgo in userspace, errno.h gets parsed and the go include file
sysinfo.go is generated.
Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED
is defined later on in errno.h, this leads to go complaining that EREFUSED
isn't defined yet.
Fix this trivial problem by moving the define of EREFUSED down after
ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

Make the hardened user-copy code depend on having a hardened allocator
The kernel test robot reported a usercopy failure in the new hardened
sanity checks, due to a page-crossing copy of the FPU state into the
task structure.
This happened because the kernel test robot was testing with SLOB, which
doesn't actually do the required book-keeping for slab allocations, and
as a result the hardening code didn't realize that the task struct
allocation was one single allocation - and the sanity checks fail.
Since SLOB doesn't even claim to support hardening (and you really
shouldn't use it), the straightforward solution is to just make the
usercopy hardening code depend on the allocator supporting it.

locking/barriers: Suppress sparse warnings in lockless_dereference()
After Peter's commit:
331b6d8c7afc ("locking/barriers: Validate lockless_dereference() is used on a pointer type")
... we get a lot of sparse warnings (one for every rcu_dereference, and more)
since the expression here is assigning to the wrong address space.
Instead of validating that 'p' is a pointer this way, instead make
it fail compilation when it's not by using sizeof(*(p)). This will
not cause any sparse warnings (tested, likely since the address
space is irrelevant for sizeof), and will fail compilation when
'p' isn't a pointer type.

As Peter explained:
[...] lockless_dereference() is _stronger_ than READ_ONCE(), not weaker.
[...]
Also, clue is in the name: 'dereference', you don't actually dereference
the pointer here, only load it.
My next patch breaks the compile without this revert, because it assumes
you want to deference and thus also need the struct type visible (which
it isn't here), so revert it.

arm64: Fix shift warning in arch/arm64/mm/dump.c
When building with 48-bit VAs and 16K page configuration, it's possible

arch/arm64/mm/dump.c: In function ‘walk_pud’:

sched/cputime: Resync steal time when guest & host lose sync
Commit:
57430218317e ("sched/cputime: Count actually elapsed irq & softirq time")
... fixed a bug but also triggered a regression:
On an i5 laptop, 4 pCPUs, 4vCPUs for one full dynticks guest, there are four
CPU hog processes(for loop) running in the guest, I hot-unplug the pCPUs
on host one by one until there is only one left, then observe CPU utilization
via 'top' in the guest, it shows:
100% st for cpu0(housekeeping)
75% st for other CPUs (nohz full mode)
However, w/o this commit it shows the correct 75% for all four CPUs.
When a guest is interrupted for a longer amount of time, missed clock ticks
are not redelivered later. Because of that, we should not limit the amount
of steal time accounted to the amount of time that the calling functions
think have passed.
However, the interval returned by account_other_time() is NOT rounded down
to the nearest jiffy, while the base interval in get_vtime_delta() it is
subtracted from is, so the max cputime limit is required to avoid underflow.
This patch fixes the regression by limiting the account_other_time() from
get_vtime_delta() to avoid underflow, and lets the other three call sites
(in account_other_time() and steal_account_process_time()) account however
much steal time the host told us elapsed.

perf/core: Update filters only on executable mmap
Function perf_event_mmap() is called by the MM subsystem each time
part of a binary is loaded in memory. There can be several mapping
for a binary, many times unrelated to the code section.
Each time a section of a binary is mapped address filters are
updated, event when the map doesn't pertain to the code section.
The end result is that filters are configured based on the last map
event that was received rather than the last mapping of the code
segment.
For example if we have an executable 'main' that calls library
'libcstest.so.1.0', and that we want to collect traces on code
that is in that library. The perf cmd line for this scenario
would be:
perf record -e cs_etm// --filter 'filter 0x72c/0x40@/opt/lib/libcstest.so.1.0' --per-thread ./main
Resulting in binaries being mapped this way:

Before 'main()' can execute 'libcstest.so.1.0' has to be loaded in
memory. Once that has been done perf_event_mmap() has been called
4 times, with the last map starting at address 0x7fa25ce000 and
the address filter configured to start filtering when the
IP has passed over address 0x0x7fa25ce72c (0x7fa25ce000 + 0x72c).
But that is wrong since the code segment for library 'libcstest.so.1.0'
as been mapped at 0x7fa25bd000, resulting in traces not being

This patch corrects the situation by requesting that address

The reason for the panic is wrong value of __max_logical_packages,
which lets logical_package_map uninitialized and the uncore code
relying on this map being properly initialized (maybe we should
add some safety checks there as well).
The __max_logical_packages is computed as:
DIV_ROUND_UP(total_cpus, ncpus);
- ncpus being number of cores
With above BIOS setup we get total_cpus == 16 which set
__max_logical_packages to 2 (ncpus is 12).
Once topology_update_package_map processes CPU with logical
pkg over 2 we display above messages and fail to initialize
the physical_to_logical_pkg map, which makes the uncore code
crash.
The fix is to remove logical_package_map bitmap completely
and keep and update the logical_packages number instead.
After we enumerate all the present CPUs, we check if the
enumerated logical packages count is within its computed
maximum from BIOS data.
If it's not the case, we set this maximum to the new enumerated
value and freeze any new addition of logical packages.
The freeze is because lot of init code like uncore/rapl/cqm
depends on having maximum logical package value set to allocate
their data, so we can't change it later on.
Prarit Bhargava tested the patch and confirms that it solves
the problem:

As pointed out by Jamal, an action could be shared by

Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.
The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

mlxsw: spectrum: Allow packets to be trapped from any PG
When packets enter the device they are classified to a priority group
(PG) buffer based on their PCP value. After their egress port and
traffic class are determined they are moved to the switch's shared
buffer and await transmission, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Packets scheduled to transmission through CPU port (trapped to CPU) use
traffic class 7, which has a zero maximum and minimum quotas. However,
when such packets arrive from PG 0 they are admitted to the shared
buffer as PG 0 has a non-zero minimum quota.
Allow all packets to be trapped to the CPU - regardless of the PG they
were classified to - by assigning a 10KB minimum quota for CPU port and
TC7.

we do for primary_switch() and secondary_switch() in head.S.

arm64: Fix NUMA build error when !CONFIG_ACPI
Since asm/acpi.h is only included by linux/acpi.h when CONFIG_ACPI is
enabled, disabling the latter leads to the following build error on
arm64:
arch/arm64/mm/numa.c: In function ‘arm64_numa_init’:
arch/arm64/mm/numa.c:395:24: error: ‘arm64_acpi_numa_init’ undeclared (first use in this function)
if (!acpi_disabled && !numa_init(arm64_acpi_numa_init))
This patch include the asm/acpi.h explicitly in arch/arm64/mm/numa.c for
the arm64_acpi_numa_init() definition.

Change my email address to kernel.org account instead of Samsung one.
Add Bartlomiej Zolnierkiewicz as a co-maintainer of Maxim and Samsung
PMIC drivers. These are used on many of our boards along with Exynos
SoCs and Samsung R&D Institute Poland can still take care of them.
