We need more space to save WoL context. So lets allocate memory
for ax88179_data instead of using struct usbnet data field which
only supports 5 words. We continue to use the struct usbnet data
field for multicast filters. However since we no longer have the
private data stored there, we can shift it to the beginning.

This adds broadcast support for BTPROTO_ISO by extending the

can set the broadcast address when receiving, the SID and the BIS
indexes it wants to synchronize.

Broadcaster -> uses connect with address set to BDADDR_ANY:
> tools/isotest -s 00:00:00:00:00:00

This reverts commit 4a41f453bedfd5e9cd040bad509d9da49feb3e2c.
This to-be-reverted commit was meant to apply a stricter rule for the
stack to enter pingpong mode. However, the condition used to check for
interactive session "before(tp->lsndtime, icsk->icsk_ack.lrcvtime)" is
jiffy based and might be too coarse, which delays the stack entering
pingpong mode.
We revert this patch so that we no longer use the above condition to
determine interactive session, and also reduce pingpong threshold to 1.
Fixes: 4a41f453bedf ("tcp: change pingpong threshold to 3")

Because of how struct msghdr is usually initialised some fields and
sg_from_iter in particular might be left out not initialised, so we
can't safely use it in __zerocopy_sg_from_iter().
For now use the callback only when there is ->msg_ubuf set relying on
the fact that they're used together and we properly zero ->msg_ubuf.

Simplify the logic that selects bpf_prog_pack_size, and always use
(PMD_SIZE * num_possible_nodes()). This is a good tradeoff, as most of
the performance benefit observed is from less direct map fragmentation [0].
Also, module_alloc(4MB) may not allocate 4MB aligned memory. Therefore,
we cannot use (ptr & bpf_prog_pack_mask) to find the correct address of
bpf_prog_pack. Fix this by checking the header address falls in the range
of pack->ptr and (pack->ptr + bpf_prog_pack_size).

When tracing a function with IPMODIFY ftrace_ops (livepatch), the bpf
trampoline must follow the instruction pointer saved on stack. This needs
extra handling for bpf trampolines with BPF_TRAMP_F_CALL_ORIG flag.
Implement bpf_tramp_ftrace_ops_func and use it for the ftrace_ops used
by BPF trampoline. This enables tracing functions with livepatch.
This also requires moving bpf trampoline to *_ftrace_direct_mult APIs.

Currently we call the original function by using the absolute address
given at the JIT generation. That's not usable when having trampoline
attached to multiple functions, or the target address changes dynamically
(in case of live patch). In such cases we need to take the return address
from the stack.
Adding support to retrieve the original function address from the stack
by adding new BPF_TRAMP_F_ORIG_STACK flag for arch_prepare_bpf_trampoline
function.
Basically we take the return address of the 'fentry' call:
function + 0: call fentry # stores 'function + 5' address on stack
function + 5: ...
The 'function + 5' address will be used as the address for the
original function to call.

IPMODIFY (livepatch) and DIRECT (bpf trampoline) ops are both important
users of ftrace. It is necessary to allow them work on the same function
at the same time.
First, DIRECT ops no longer specify IPMODIFY flag. Instead, DIRECT flag is
handled together with IPMODIFY flag in __ftrace_hash_update_ipmodify().
Then, a callback function, ops_func, is added to ftrace_ops. This is used
by ftrace core code to understand whether the DIRECT ops can share with an
IPMODIFY ops. To share with IPMODIFY ops, the DIRECT ops need to implement
the callback function and adjust the direct trampoline accordingly.
If DIRECT ops is attached before the IPMODIFY ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_PEER on the DIRECT ops before registering the
IPMODIFY ops.
If IPMODIFY ops is attached before the DIRECT ops, ftrace core code calls
ENABLE_SHARE_IPMODIFY_SELF in __ftrace_hash_update_ipmodify. Owner of the
DIRECT ops may return 0 if the DIRECT trampoline can share with IPMODIFY,
so error code otherwise. The error code is propagated to
register_ftrace_direct_multi so that onwer of the DIRECT trampoline can
handle it properly.
For more details, please refer to comment before enum ftrace_ops_cmd.

If ACPI_FADT_LOW_POWER_S0 is not set, this doesn't mean that low-power
S0 idle is not usable. It merely means that using S3 on the given
system is more beneficial from the energy saving perspective than using
low-power S0 idle, as long as S3 is supported.
Suspend-to-idle is still a valid suspend mode if ACPI_FADT_LOW_POWER_S0
is not set and the pm_suspend_via_firmware() check in pch_wpt_suspend()
is sufficient to distinguish suspend-to-idle from S3, so drop the
confusing ACPI_FADT_LOW_POWER_S0 check.

When CONFIG_COMPAT=y the vdso_install target fails:

INSTALL vdso.so
make[1]: *** No rule to make target 'vdso_install'. Stop.
make: *** [arch/riscv/Makefile:112: vdso_install] Error 2
The problem is that arch/riscv/kernel/compat_vdso/Makefile doesn't

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU fix from Paul McKenney:
"This contains a pair of commits that fix 282d8998e997 ("srcu: Prevent
expedited GPs and blocking readers from consuming CPU"), which was
itself a fix to an SRCU expedited grace-period problem that could
prevent kernel live patching (KLP) from completing.
That SRCU fix for KLP introduced large (as in minutes) boot-time
delays to embedded Linux kernels running on qemu/KVM. These delays
were due to the emulation of certain MMIO operations controlling
memory layout, which were emulated with one expedited grace period per
access. Common configurations required thousands of boot-time MMIO
accesses, and thus thousands of boot-time expedited SRCU grace
periods.
In these configurations, the occasional sleeps that allowed KLP to
proceed caused excessive boot delays. These commits preserve enough
sleeps to permit KLP to proceed, but few enough that the virtual
embedded kernels still boot reasonably quickly.
This represents a regression introduced in the v5.19 merge window, and
the bug is causing significant inconvenience"
