Instead of using a global variable mptcp_connect, this patch added
a new local variable extra_args in do_transfer() to store the extra
arguments passing to the mptcp_connect commands.
This patch also renamed the speed level 'least' to 'speed_*'. This
more flexible way can avoid the need to add new speed levels in the
future.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on
static allocation of IRQ resources in DT core code, this
causes an issue when using hierarchical interrupt domains
using "interrupts" property in the node as this bypassed
the hierarchical setup and messed up the irq chaining.
In preparation for removal of static setup of IRQ resource
from DT core code use platform_get_irq().

We've added 32 non-merge commits during the last 14 day(s) which contain
a total of 59 files changed, 1038 insertions(+), 473 deletions(-).
The main changes are:
1) Optimize BPF stackmap's build_id retrieval by caching last valid build_id,
as consecutive stack frames are likely to be in the same VMA and therefore
have the same build id, from Hao Luo.
2) Several improvements to arm64 BPF JIT, that is, support for JITing
the atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and lastly
atomic[64]_{xchg|cmpxchg}. Also fix the BTF line info dump for JITed
programs, from Hou Tao.
3) Optimize generic BPF map batch deletion by only enforcing synchronize_rcu()
barrier once upon return to user space, from Eric Dumazet.
4) For kernel build parse DWARF and generate BTF through pahole with enabled
multithreading, from Kui-Feng Lee.
5) BPF verifier usability improvements by making log info more concise and
replacing inv with scalar type name, from Mykola Lysenko.
6) Two follow-up fixes for BPF prog JIT pack allocator, from Song Liu.
7) Add a new Kconfig to allow for loading kernel modules with non-matching
BTF type info; their BTF info is then removed on load, from Connor O'Brien.
8) Remove reallocarray() usage from bpftool and switch to libbpf_reallocarray()
in order to fix compilation errors for older glibc, from Mauricio Vásquez.
9) Fix libbpf to error on conflicting name in BTF when type declaration
appears before the definition, from Xu Kuohai.
10) Fix issue in BPF preload for in-kernel light skeleton where loaded BPF
program fds prevent init process from setting up fd 0-2, from Yucong Sun.
11) Fix libbpf reuse of pinned perf RB map when max_entries is auto-determined
by libbpf, from Stijn Tintel.

Both hci_find_adv_instance and hci_remove_adv_instance have a comment
above their function definition saying that these two functions require
the caller to hold the hdev->lock lock. However, hci_le_ext_adv_term_evt
does not acquire that lock and neither does its caller hci_le_meta_evt
(hci_le_meta_evt calls hci_le_ext_adv_term_evt via an indirect function
call because of the lookup in hci_le_ev_table).
The other event handlers all acquire and release the hdev->lock and they
follow the rule that hci_find_adv_instance and hci_remove_adv_instance
must be called while holding the hdev->lock lock.
The solution is to make sure hci_le_ext_adv_term_evt also acquires and
releases the hdev->lock lock. The check on ev->status which logs a
warning and does an early return is not covered by the lock because
other functions also access ev->status without holding the lock.

There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.
But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek chipset like MT7921

Add AF_XDP zero-copy support for NFP
Niklas Söderlund says:
This series adds AF_XDP zero-copy support for the NFP driver. The series
is based on previous work done by Jakub Kicinski.
Patch 1/5 and 2/5 prepares the driver for AF_XDP support by refactoring
functions that will act differently once AF_XDP is active or not making
the driver easier to read and by preparing some functions to be reused
outside the local file scope. Patch 3/5 and 4/5 prepares the driver for
dealing the UMEM while finally patch 5/5 adds AF_XDP support.

This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so
by adding a separate NAPI poll function that is attached to a each
channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and
restored when the XSK socket is terminated, this is done per channel.
Support for XDP_TX is implemented and the XDP buffer can safely be moved
from the Rx to the Tx queue and correctly freed and returned to the XSK
pool once it's transmitted.
Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS
will allocate a new buffer and copy the zero-copy frame prior
passing it to the kernel stack.
