The CCI PMU driver bears some legacy remnants of the arm_pmu framework
from when it was split in c6f85cb4305b ("bus: cci: move away from
arm_pmu framework"). In particular this perf_pmu_{dis,en}able() dance
around pmu->add which was fixed for arm_pmu in a9e469d1c89b

Fill in the few extra bits and annotations needed to make the driver
work properly as a module, and jiggle the Kconfig to expose the
driver-level ARM_CCI_PMU option.

In SUSE, we need a reliable stack unwinder for kernel live patching, but
we do not want to enable frame pointers for performance reasons. So
after the previous patches to make the ORC reliable, mark ORC as a
reliable stack unwinder on x86.

save_stack_trace_reliable now returns "non reliable" when there are
kernel pt_regs on stack. This means an interrupt or exception happened
somewhere down the route. It is a problem for the frame pointer
unwinder, because the frame might not have been set up yet when the irq
happened, so the unwinde

The existing UNWIND_HINT_EMPTY annotations happen to be good indicators
of where entry code calls into C code for the first time. So also use
them to mark the end of the stack for the ORC unwinder.
Use that information to set unwind->error if the ORC unwinder doesn't
unwind
Josh pointed out, that there is no way a frame can be after user regs.
So remove the last unwind and the check.

The stack unwinding can sometimes fail yet. Especially with the

Without rtnl lock protection it is no longer safe to use pointer to tc
action without holding reference to it. (it can be destroyed concurrently)
Remove unsafe action idr lookup function. Instead of it, implement safe tcf

This is the sync up with the canonical definition of the keyboard
protocol in Xen:
1. Add missing string constants for {feature|request}-raw-pointer
to align with the rest of the interface file.
2. Add new XenStore feature fields, so it is possible to individuall
From: Oleksandr Andrushchenko
It is now only possible to control if multi-touch virtual device
is created or not (via the corresponding XenStore entries),
but keyboard and pointer devices are always created.
In some cases this is not desirable. For example, if virtual

Hi,
This patchset adds support for PUD hugepages at stage 2. This feature
is useful on cores that have support for large sized TLB mappings
(e.g., 1GB for 4K granule). Previous postings can be found at
[0][1][2].
Support is added to code that is shared between arm and arm64. Dummy
helpers for arm
The code for operations such as marking the pfn as dirty, and
dcache/icache maintenance during stage 2 fault handling is duplicated
between normal pages and PMD hugepages.
Instead of creating another copy of the operations when we introduce
PUD hugepages, let's share them across the different page
Introduce helpers to abstract architectural handling of the conversion
of pfn to page table entries and marking a PMD page table entry as a
block entry.
The helpers are introduced in preparation for supporting PUD hugepages
at stage 2 - which are supported on arm64 but do not exist on arm.
Signed
KVM only supports PMD hugepages at stage 2. Extend the stage 2 fault
handling to add support for PUD hugepages.
Addition of pud hugepage support enables additional hugepage
sizes (e.g., 1G with 4K granule) which can be useful on cores that
support mapping larger block sizes in the TLB entries.

In preparation for creating PUD hugepages at stage 2, add support for
write protecting PUD hugepages when they are encountered. Write
protecting guest tables is used to track dirty pages when migrating
VMs.
Also, provide trivial implementations of required kvm_s2pud_* helpers
to allow sharing of c

As dev_pm_domain_attach() isn't the only way to assign PM domain pointers
to devices, clearly we must allow a device to have the pointer already
being assigned. For this reason, return 0 instead of -EEXIST.
