This is an include only used by the Linux kernel, so no need to worry

a224f284d0 staging: vchiq: Move copy callback handling into vchiq
All vchi users use the kernel variant of the copy callback. The only
user for the user space variant of the copy callback is in the ioctl
implementation. So move all this copying logic into vchiq, and expose a
new function that explicitly passes kernel messages.

1fd4fb8c62 staging: most: usb: replace code to calculate array index
This patch removes the expression that makes use of a priori knowledge
about channel numbers to calculate an array index.
The expression 'peer = 1 - channel' utilizes the fact that an USB interface
that operates on the asynchronous data of the Network only has two
endpoints. Hence, channel being 0 or 1. The replacement is more simple and
less confusing when reading the code.

size added to extra_tx_headroom the largest possible size.

The CONTEXT enums types are aligned with usb ones and CONTEXT_MGMT_PACKET
is removed and is never be used.

The skb_push in vnt_tx_packet is now only ever used with
vnt_get_hdr_size with variables tx_bytes and tx_header_size removed.

buf_len in vnt_usb_send_context is no longer used and replaced with
urb->actual_length in vnt_tx_context_complete.

vlan_for_each() are required to be called with rtnl_lock taken, otherwise
ASSERT_RTNL() warning will be triggered - which happens now during System
resume from suspend:
  cpsw_suspend()

      |- cpsw_purge_all_mc()
         |- vlan_for_each()
            |- ASSERT_RTNL();

Hence, fix it by surrounding cpsw_ndo_stop() by rtnl_lock/unlock() calls.

0ddfee1fee net: phy: mscc: fix initialization of the MACsec protocol mode
At the very end of the MACsec block initialization in the MSCC PHY
driver, the MACsec "protocol mode" is set. This setting should be set
based on the PHY id within the package, as the bank used to access the
register used depends on this. This was not done correctly, and only the
first bank was used leading to the two upper PHYs being unstable when
using the VSC8584. This patch fixes it.

31096c3e8b net: stmmac: don't attach interface until resume finishes
Commit 14b41a2959 ("net: stmmac: Delete txtimer in suspend") was the
first attempt to fix a race between mod_timer() and setup_timer()
during stmmac_resume(). However the issue still exists as the commit
only addressed half of the issue.

Same race can still happen as stmmac_resume() re-attaches interface
way too early - even before hardware is fully initialized.  Worse,
doing so allows network traffic to restart and stmmac_tx_timer_arm()
being called in the middle of stmmac_resume(), which re-init tx timers
in stmmac_init_coalesce().  timer_list will be corrupted and system
crashes as a result of race between mod_timer() and setup_timer().

0cfc8a8d70 sparc32: fix page table traversal in srmmu_nocache_init()
The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to
page table entry to access srmmu_nocache_pool.

But since sparc32 has only three actual page table levels, pgd, p4d and
pud are essentially the same thing and pgd_offset() and p4d_offset() are
no-ops, the __nocache_fix() should be done only at PUD level.

Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it
only for PUD and lower levels.
