The idea for type_check in dev_get_nest_level() was to count the number
of nested devices of the same type (currently, only macvlan or vlan
devices).
This prevented the false positive lockdep warning on configurations such
as:
eth0 <--- macvlan0 <--- vlan0 <--- macvlan1
However, this doesn't prevent a warning on a configuration such as:
eth0 <--- macvlan0 <--- vlan0
eth1 <--- vlan1 <--- macvlan1
In this case, all the locks end up with a nesting subclass of 1, so
lockdep thinks that there is still a deadlock:
- in the first case we have (macvlan_netdev_addr_lock_key, 1) and then
take (vlan_netdev_xmit_lock_key, 1)
- in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then
take (macvlan_netdev_addr_lock_key, 1)
By removing the linktype check in dev_get_nest_level() and always
incrementing the nesting depth, lockdep considers this configuration
valid.

This backward compatibility has been around for more than ten years,
since Yasuyuki Kozakai introduced IPv6 in conntrack. These days, we have
alternate /proc/net/nf_conntrack* entries, the ctnetlink interface and
the conntrack utility got adopted by many people in the user community
according to what I observed on the netfilter user mailing list.
So let's get rid of this.

not need to be exported as symbol anymore.

While hashing out BPF's current_task_under_cgroup helper bits, it came
to discussion that the skb_in_cgroup helper name was suboptimally chosen.
Tejun says:
So, I think in_cgroup should mean that the object is in that
particular cgroup while under_cgroup in the subhierarchy of that
cgroup. Let's rename the other subhierarchy test to under too. I
think that'd be a lot less confusing going forward.
[...]
It's more intuitive and gives us the room to implement the real
"in" test if ever necessary in the future.
Since this touches uapi bits, we need to change this as long as v4.8
is not yet officially released. Thus, change the helper enum and rename
related bits.

This adds a bpf helper that's similar to the skb_in_cgroup helper to check
whether the probe is currently executing in the context of a specific
subset of the cgroupsv2 hierarchy. It does this based on membership test
for a cgroup arraymap. It is invalid to call this in an interrupt, and
it'll return an error. The helper is primarily to be used in debugging
activities for containers, where you may have multiple programs running in
a given top-level "container".

There is a GCC false-warning issue on specific GCC versions that
"strchr" will be preprocessed and extracted to contain
!__buildin_constant_p() checker and it surely is a constant logical
value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a

The regression is triggered after the standard headers are re-ordered in
the EFI porting task. This patch fixes this regression by moving the
workaround to a new position after including all other standard headers.

ACPICA commit a760a98ec84b1ec782e0bff5f6612af6fb89c10c
Originally compiler specific headers are included by the host-specific
headers. This makes build configuration management very inconvenient. And
many inclusion order issues can be hidden accross different host OSes. It
will then likely that some host builds will be broken just because of
fixing some inclusion order issues for other host builds.
This patch splits the compiler-specific header inclusions out of the
host-specific headers so that compiler-specific inclusion order issues will
not get entangled in the host-specific inclusion orders.
Note that intel compiler defines __GNUC__, so this patch contains special
handling because acintel.h and acgcc.h should be mutual exclusive.

ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09
When /Za is specified, headers of some Windows SDKs contain bugs breaking
VC builds, and MSVC9's default SDK is one of such header-buggy library.
In order to solve this issue, many VC developers stop using /Za. However
we've been asked to have this fixed without removing /Za.
In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h>
to be the last standard file included by every source file in the projects.
This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this
issue can be fixed by ensuring that "acapps.h" is always the last standard
file included by all of the ACPICA source files. This is in fact also a
useful cleanup because applications can only include one header (e.x.,
acpidump.h) instead of including acapps.h separately. Lv Zheng.
Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d
EFI header should use standard C library stuffs (integer types and IO
handles) rather than implementing such standard stuffs.
This patch fixes this issue by:
1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n;
2. Defining EFI types using standard integer types and standard IO handles;
3. Tuning header inclusion order and environment definition order;
4. Removing wrong standard header inclusion from ACPICA core files;
5. Moving several application headers from acpidump.h to acenv.h.
This patch corrects some of them. Lv Zheng.

ACPICA commit 4aab18466b56f3660f27cffd3c0160900737f844
When mini C library is used, we should have the following macros undefined.
The only user should be the EFI applications:
ACPI_USE_SYSTEM_CLIBRARY=n
ACPI_USE_STANDARD_HEADERS=n
All other applications uses the compiler specific library:
ACPI_USE_SYSTEM_CLIBRARY=y
ACPI_USE_STANDARD_HEADERS=y
Linux/BSD kernels are the kind of hosts providing C library but does not
provide the standard headers:
ACPI_USE_SYSTEM_CLIBRARY=y
ACPI_USE_STANDARD_HEADERS=n
But the above logic hasn't been synchronized between the header files.
This patch synchronizes all header files to correct C library usages for
different platforms. This patch moves all ACPI_USE_SYSTEM_CLIRARY and
ACPI_USE_STANDARD_HEADERS to the top most lines of a platform specific
header.
After synchronization, ACPI_USE_SYSTEM_CLIRARY definition can be removed
for ACPI_APPLICATION. Lv Zheng.

ACPICA commit 34ccd43af3fd1870fddfac0617dd0ba706963558
Remove all vestiges of the version 2 FADT which never was included
in the ACPI specification.
This enabled significant cleanup of both the data table compiler
and the disassembler.
Added many clarification comments to associate each FADT version
with the version of the ACPI spec where it was originally
defined.

ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14
There is a facility in Linux, developers can control the enabling/disabling
of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for
debugging purposes.
But many users expect to use this facility to implement quirks to mask a
specific GPE when there is a gap in Linux causing this GPE to flood. This
is not working correctly because currently this facility invokes
enabling/disabling counting based GPE driver APIs:
acpi_enable_gpe()/acpi_disable_gpe()
and the GPE drivers can still affect the count to mess up the GPE
masking purposes.
However, most of the IRQ chip designs allow masking/unmasking IRQs via a
masking bit which is different from the enabled bit to achieve the same
purpose. But the GPE hardware doesn't contain such a feature, this brings
the trouble.
In this patch, we introduce a software mechanism to implement the GPE
masking feature, and acpi_mask_gpe() are provided to the OSPMs to
mask/unmask GPEs in the above mentioned situation instead of
acpi_enable_gpe()/acpi_disable_gpe(). ACPICA BZ 1102. Lv Zheng.

Linux uses asmlinkage and sparse macros to mark function symbols. This

KVM devices were manipulating list data structures without any form of
synchronization, and some implementations of the create operations also
suffered from a lack of synchronization.
Now when we've split the xics create operation into create and init, we
can hold the kvm->lock mutex while calling the create operation and when
manipulating the devices list.
The error path in the generic code gets slightly ugly because we have to
take the mutex again and delete the device from the list, but holding
the mutex during anon_inode_getfd or releasing/locking the mutex in the
common non-error path seemed wrong.
