Switch ocfs2 from using sendpage() to using sendmsg() + MSG_SPLICE_PAGES so
that sendpage can be phased out.

ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
o2net_keep_resp and then passes these to sendpage. This isn't really
allowed as the lifetime of slab objects is not controlled by page ref -
though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
will, however, print a warning and give an error.
Fix it to use folio_alloc() instead to allocate a buffer for the handshake
message, keepalive request and reply messages.

Use sendmsg() with MSG_SPLICE_PAGES rather than sendpage. This allows
multiple pages and multipage folios to be passed through.
TODO: iscsit_fe_sendpage_sg() should perhaps set up a bio_vec array for the
entire set of pages it's going to transfer plus two for the header and
trailer and page fragments to hold the header and trailer - and then call
sendmsg once for the entire message.

64-bit DMA detection will fail if axienet was started before (by boot
loader, boot ROM, etc). In this state axienet will not start properly.
XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
is used to fetch the first descriptor. So iowrite32()/ioread32() trick
to this register to detect 64-bit DMA will not work.
So move axienet reset before 64-bit DMA detection.

This patch makes chk_mptcp_info() more generic to be able to check

later). New arguments are now required to get different infos from the

net: stmmac: introduce devres helpers for stmmac platform drivers
The goal of this series is two-fold: to make the API for stmmac platforms more
logically correct (by providing functions that acquire resources with release
counterparts that undo only their actions and nothing more) and to provide
devres variants of commonly use registration functions that allows to
significantly simplify the platform drivers.
The current pattern for stmmac platform drivers is to call
stmmac_probe_config_dt(), possibly the platform's init() callback and then
call stmmac_drv_probe(). The resources allocated by these calls will then
be released by calling stmmac_pltfr_remove(). This goes against the commonly
accepted way of providing each function that allocated a resource with a
function that frees it.
First: provide wrappers around platform's init() and exit() callbacks that
allow users to skip checking if the callbacks exist manually.
Second: provide stmmac_pltfr_probe() which calls the platform init() callback
and then calls stmmac_drv_probe() together with a variant of
stmmac_pltfr_remove() that DOES NOT call stmmac_remove_config_dt(). For now
this variant is called stmmac_pltfr_remove_no_dt() but once all users of
the old stmmac_pltfr_remove() are converted to the devres helper, it will be
renamed back to stmmac_pltfr_remove() and the no_dt function removed.
Finally use the devres helpers in dwmac-qco-ethqos to show how much simplier
the driver's probe() becomes.
This series obviously just starts the conversion process and other platform
drivers will need to be converted once the helpers land in net/.

Significantly simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt(). This allows to drop the goto jumps
entirely.
The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

Even when tcp_splice_read() reads all it was asked for, for blocking
sockets it'll release and immediately regrab the socket lock, loop
around and break on the while check.
Check tss.len right after we adjust it, and return if we're done.
That saves us one release_sock(); lock_sock(); pair per successful
blocking splice read.

In blamed commit, I missed that get_dist_table() was allocating
memory using GFP_KERNEL, and acquiring qdisc lock to perform
the swap of newly allocated table with current one.
In this patch, get_dist_table() is allocating memory and
copy user data before we acquire the qdisc lock.
Then we perform swap operations while being protected by the lock.
Note that after this patch netem_change() no longer can do partial changes.
If an error is returned, qdisc conf is left unchanged.
