In the simple case, each sendmsg() call generates data and eventually
a zerocopy ready notification N, where N indicates the Nth successful
invocation of sendmsg() with the MSG_ZEROCOPY flag on this socket.
TCP and corked sockets can cause send() calls to append new data to an
existing sk_buff and, thus, ubuf_info. In that case the notification
must hold a range. odify ubuf_info to store a inclusive range [N..N+m]
and add skb_zerocopy_realloc() to optionally extend an existing range.
Also coalesce notifications in this common case: if a notification
[1, 1] is about to be queued while [0, 0] is the queue tail, just modify
the head of the queue to read [0, 1].
Coalescing is limited to a few TSO frames worth of data to bound
notification latency.

Prepare the datapath for refcounted ubuf_info. Clone ubuf_info with
skb_zerocopy_clone() wherever needed due to skb split, merge, resize
or clone.
Split skb_orphan_frags into two variants. The split, merge, .. paths
support reference counted zerocopy buffers, so do not do a deep copy.
Add skb_orphan_frags_rx for paths that may loop packets to receive
sockets. That is not allowed, as it may cause unbounded latency.
Deep copy all zerocopy copy buffers, ref-counted or not, in this path.
The exact locations to modify were chosen by exhaustively searching
through all code that might modify skb_frag references and/or the
the SKBTX_DEV_ZEROCOPY tx_flags bit.
The changes err on the safe side, in two ways.
(1) legacy ubuf_info paths virtio and tap are not modified. They keep
a 1:1 ubuf_info to sk_buff relationship. Calls to skb_orphan_frags
still call skb_copy_ubufs and thus copy frags in this case.
(2) not all copies deep in the stack are addressed yet. skb_shift,
skb_split and skb_try_coalesce can be refined to avoid copying.
These are not in the hot path and this patch is hairy enough as
is, so that is left for future refinement.

The send call ignores unknown flags. Legacy applications may already
unwittingly pass MSG_ZEROCOPY. Continue to ignore this flag unless a
socket opts in to zerocopy.
Introduce socket option SO_ZEROCOPY to enable MSG_ZEROCOPY processing.
Processes can also query this socket option to detect kernel support
for the feature. Older kernels will return ENOPROTOOPT.

The kernel supports zerocopy sendmsg in virtio and tap. Expand the
infrastructure to support other socket types. Introduce a completion
notification channel over the socket error queue. Notifications are
returned with ee_origin SO_EE_ORIGIN_ZEROCOPY. ee_errno is 0 to avoid
blocking the send/recv path on receiving notifications.
Add reference counting, to support the skb split, merge, resize and
clone operations possible with SOCK_STREAM and other socket types.

Refine skb_copy_ubufs to support compound pages. With upcoming TCP
zerocopy sendmsg, such fragments may appear.
The existing code replaces each page one for one. Splitting each
compound page into an independent number of regular pages can result
in exceeding limit MAX_SKB_FRAGS if data is not exactly page aligned.
Instead, fill all destination pages but the last to PAGE_SIZE.
Split the existing alloc + copy loop into separate stages:
1. compute bytelength and minimum number of pages to store this.
2. allocate
3. copy, filling each page except the last to PAGE_SIZE bytes
4. update skb frag array

There are quite a number of occurrences in the kernel of the pattern
if (dst != src)
memcpy(dst, src, walk.total % AES_BLOCK_SIZE);
crypto_xor(dst, final, walk.total % AES_BLOCK_SIZE);
or
crypto_xor(keystream, src, nbytes);
memcpy(dst, keystream, nbytes);
where crypto_xor() is preceded or followed by a memcpy() invocation
that is only there because crypto_xor() uses its output parameter as
one of the inputs. To avoid having to add new instances of this pattern
in the arm64 code, which will be refactored to implement non-SIMD
fallbacks, add an alternative implementation called crypto_xor_cpy(),
taking separate input and output arguments. This removes the need for
the separate memcpy().

and commit b423cb10807b ("ipv4: fib: Export free_fib_info()") add an
helper to hold a reference on rt6_info and export rt6_release() to drop

This is needed so that drivers capable of FIB offload could hold a

the route has been programmed to the device's tables.

Dump all the FIB tables in each net namespace upon registration to the
FIB notification chain so that the callee will have a complete view of
the tables.
The integrity of the dump is ensured by a per-table sequence counter
that is incremented (under write lock) whenever a route is added or
deleted from the table.
All the sequence counters are read (under each table's read lock) and
summed, prior and after the dump. In case the counters differ, then the
dump is either restarted or the registration fails.
While it's possible for a table to be modified after its counter has
been read, this isn't really a problem. In case it happened before it
was read the second time, then the comparison at the end will fail. If
it happened afterwards, then we're guaranteed to be notified about the
change, as the notification block is registered prior to the second
read.

As with IPv4, allow listeners of the FIB notification chain to receive
notifications whenever a route is added, replaced or deleted. This is
done by placing calls to the FIB notification chain in the two lowest
level functions that end up performing these operations - namely,
fib6_add_rt2node() and fib6_del_route().
Unlike IPv4, APPEND notifications aren't sent as the kernel doesn't
distinguish between "append" (NLM_F_CREATE|NLM_F_APPEND) and "prepend"
(NLM_F_CREATE). If NLM_F_EXCL isn't set, duplicate routes are always
added after the existing duplicate routes.

Unlike the routing tables, the FIB rules share a common core, so instead
of replicating the same logic for each address family we can simply dump
the rules and send notifications from the core itself.
To protect the integrity of the dump, a rules-specific sequence counter
is added for each address family and incremented whenever a rule is
added or deleted (under RTNL).

The FIB notification chain is currently soley used by IPv4 code.
However, we're going to introduce IPv6 FIB offload support, which
requires these notification as well.
As explained in commit c3852ef7f2f8 ("ipv4: fib: Replay events when
registering FIB notifier"), upon registration to the chain, the callee
receives a full dump of the FIB tables and rules by traversing all the
net namespaces. The integrity of the dump is ensured by a per-namespace
sequence counter that is incremented whenever a change to the tables or
rules occurs.
In order to allow more address families to use the chain, each family is
expected to register its fib_notifier_ops in its pernet init. These
operations allow the common code to read the family's sequence counter
as well as dump its tables and rules in the given net namespace.
Additionally, a 'family' parameter is added to sent notifications, so
that listeners could distinguish between the different families.
Implement the common code that allows listeners to register to the chain
and for address families to register their fib_notifier_ops. Subsequent
patches will implement these operations in IPv6.
In the future, ipmr and ip6mr will be extended to provide these
notifications as well.

ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5
In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.
This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.
For Linux kernel, this patch is a functional no-op.

on a Mac to support Apple device properties in AML. The DMI checks are
performed for every single device, adding overhead for everything x86
that isn't Apple, which is the majority. Rafael and Andy therefore
request to perform the DMI match only once and cache the result.
Outside of ACPI various other Apple DMI checks exist and it seems
reasonable to use the cached value there as well. Rafael, Andy and
Darren suggest performing the DMI check in arch code and making it
available with a header in include/linux/platform_data/x86/.
To this end, add early_platform_quirks() to arch/x86/kernel/quirks.c
to perform the DMI check and invoke it from setup_arch(). Switch over
all existing Apple DMI checks, thereby fixing two deficiencies:
* They are now #defined to false on non-x86 arches and can thus be
optimized away if they're located in cross-arch code.
* Some of them only match "Apple Inc." but not "Apple Computer, Inc.",
which is used by BIOSes released between January 2006 (when the first
x86 Macs started shipping) and January 2007 (when the company name
changed upon introduction of the iPhone).

The motivation behind this new interface is expose at runtime the
creation of new OA configs which can be used as part of the i915 perf
open interface. This will enable the kernel to learn new configs which
may be experimental, or otherwise not part of the core set currently
available through the i915 perf interface.
v2: Drop DRM_ERROR for userspace errors (Matthew)
Add padding to userspace structure (Matthew)
s/guid/uuid/ (Matthew)
v3: Use u32 instead of int to iterate through registers (Matthew)
v4: Lock access to dynamic config list (Lionel)
v5: by Matthew:
Fix uninitialized error values
Fix incorrect unwiding when opening perf stream
Use kmalloc_array() to store register
Use uuid_is_valid() to valid config uuids
Declare ioctls as write only
Check padding members are set to 0
by Lionel:
Return ENOENT rather than EINVAL when trying to remove non
existing config
v6: by Chris:
Use ref counts for OA configs
Store UUID in drm_i915_perf_oa_config rather then using pointer
Shuffle fields of drm_i915_perf_oa_config to avoid padding
v7: by Chris
Rename uapi pointers fields to end with '_ptr'
v8: by Andrzej, Marek, Sebastian
Update register whitelisting
by Lionel
Add more register names for documentation
Allow configuration programming in non-paranoid mode
Add support for value filter for a couple of registers already
programmed in other part of the kernel
v9: Documentation fix (Lionel)
Allow writing WAIT_FOR_RC6_EXIT only on Gen8+ (Andrzej)
v10: Perform read access_ok() on register pointers (Lionel)

This patch is to remove the typedef sctp_auth_chunk_t, and
replace with struct sctp_auth_chunk in the places where it's
using this typedef.
It is also to use sizeof(variable) instead of sizeof(type).
