6a1961bc9c atp870u: Introduce atp_set_host_id
The code for setting host adapter ID is the same for all chips.
Move it to a common function.

c751d9f1fc atp870u: Fix incorrect writeb_io access to register 0x3a
The ioport region is 0x20 bytes long so accessing 0x3a register using
writeb_io is incorrect. Use writeb_base instead.
There's no change in behavior as 870 chips have ioport = baseport.

d282e2b383 SCSI: initio: remove duplicate module device table
The initio driver has for many years had two copies of the
same module device table. One of them is also used for registering
the other driver, the other one is entirely useless after the
large scale cleanup that Alan Cox did back in 2007.

The compiler warns about this whenever the driver is built-in:

drivers/scsi/initio.c:131:29: warning: 'i91u_pci_devices' defined but not used [-Wunused-variable]

This removes the extraneous table and the warning.

and adds a comment explaining why it's okay to return a value other than
0 upon error. Some drivers might actually change flags and return an
error so it's better to fire a spurious notification rather than miss
these.

a3a116e04c af_unix: take receive queue lock while appending new skb
While possibly in future we don't necessarily need to use
sk_buff_head.lock this is a rather larger change, as it affects the
af_unix fd garbage collector, diag and socket cleanups. This is too much
for a stable patch.

For the time being grab sk_buff_head.lock without disabling bh and irqs,
so don't use locked skb_queue_tail.

by splitting up the huge rtnl_fill_ifinfo into some smaller ones, so we
don't have the huge frame allocations at the same time.

19125c1a4f net: use skb_clone to avoid alloc_pages failure.
1. new skb only need dst and ip address(v4 or v6).
2. skb_copy may need high order pages, which is very rare on long running server.

321beec504 net: phy: Use interrupts when available in NOLINK state
The NOLINK state will poll the phy once a second to see if the link
has come up. If the phy has an interrupt line, this polling can be
skipped, since the phy should interrupt when the link returns.

The 88E1540 can be found embedded in the Marvell 88E6352 switch.  It
is compatible with the 88E1510, so add support for it, using the

ec0738db8d arm64: bpf: make BPF prologue and epilogue align with ARM64 AAPCS
Save and restore FP/LR in BPF prog prologue and epilogue, save SP to FP
in prologue in order to get the correct stack backtrace.

However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to
change during function call so it may cause the BPF prog stack base address
change too.

Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee
saved register, so it will keep intact during function call.
It is initialized in BPF prog prologue when BPF prog is started to run
everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep
them intact for the outside of BPF. Actually, x26 is unnecessary, but SP
requires 16 bytes alignment.

So, the BPF stack layout looks like:

                                 high
         original A64_SP =>   0:+-----+ BPF prologue
                                |FP/LR|
         current A64_FP =>  -16:+-----+
                                | ... | callee saved registers
                                +-----+
                                |     | x25/x26
         BPF fp register => -80:+-----+
                                |     |
                                | ... | BPF prog stack
                                |     |
                                |     |
         current A64_SP =>      +-----+
                                |     |
                                | ... | Function call stack
                                |     |
                                +-----+

ipvlan_handle_frame is a rx_handler, and when it returns a value other
than RX_HANDLER_CONSUMED (here, NET_RX_DROP aka RX_HANDLER_ANOTHER),
__netif_receive_skb_core expects that the skb still exists and will
process it further, but we just freed it.
