These function are all called from assembler files, or from inline
assembler, so there is no immediate need for a prototype in a header,
but if -Wmissing-prototypes is enabled, the compiler warns about them:
arch/x86/xen/efi.c:130:13: error: no previous prototype for 'xen_efi_init' [-Werror=missing-prototypes]
arch/x86/platform/pvh/enlighten.c:120:13: error: no previous prototype for 'xen_prepare_pvh' [-Werror=missing-prototypes]
arch/x86/xen/enlighten_pv.c:1233:34: error: no previous prototype for 'xen_start_kernel' [-Werror=missing-prototypes]

arch/x86/entry/common.c:302:24: error: no previous prototype for 'xen_pv_evtchn_do_upcall' [-Werror=missing-prototypes]
Declare all of them in an appropriate header file to avoid the warnings.
For consistency, also move the asm_cpu_bringup_and_idle() declaration
out of smp_pv.c.

The paravirt MMU functions called via the PV_CALLEE_SAVE_REGS_THUNK()
macro can't be defined to be static, as the macro is generating a
function via asm() statement calling the paravirt MMU function.
In order to avoid warnings when specifying "-Wmissing-prototypes" for
the build, add local prototypes (there should never be any external
caller of those functions).

To facilitate diskless iSCSI boot, the firmware can place a table of
configuration details in memory called the iBFT. The presence of this
table is not specified, nor is the precise location (and it's not in the
E820) so the kernel has to search for a magic marker to find it.
When running under Xen, Dom 0 does not have access to the entire host's
memory, only certain regions which are identity-mapped which means that
the pseudo-physical address in Dom0 == real host physical address.
Add the iBFT search bounds as a reserved region which causes it to be
identity-mapped in xen_set_identity_and_remap_chunk() which allows Dom0
access to the specific physical memory to correctly search for the iBFT
magic marker (and later access the full table).
This necessitates moving the call to reserve_ibft_region() somewhat
later so that it is called after e820__memory_setup() which is when the
Xen identity mapping adjustments are applied. The precise location of
the call is not too important so I've put it alongside dmi_setup() which
does similar scanning of memory for configuration tables.
Finally in the iBFT find code, instead of using isa_bus_to_virt() which
doesn't do the right thing under Xen, use early_memremap() like the
dmi_setup() code does.
The result of these changes is that it is possible to boot a diskless
Xen + Dom0 running off an iSCSI disk whereas previously it would fail to
find the iBFT and consequently, the iSCSI root disk.

The xen_debug_interrupt() function is only called on x86, which has a
prototype in an architecture specific header, but the definition also
exists on others, where the lack of a prototype causes a W=1 warning:
drivers/xen/events/events_2l.c:264:13: error: no previous prototype for 'xen_debug_interrupt' [-Werror=missing-prototypes]
Move the prototype into a global header instead to avoid this warning.

splice, net: Switch over users of sendpage() and remove it
Here's the final set of patches towards the removal of sendpage. All the
drivers that use sendpage() get switched over to using sendmsg() with
MSG_SPLICE_PAGES.
The following changes are made:
(1) Make the protocol drivers behave according to MSG_MORE, not
MSG_SENDPAGE_NOTLAST. The latter is restricted to turning on MSG_MORE
in the sendpage() wrappers.
(2) Fix ocfs2 to allocate its global protocol buffers with folio_alloc()
rather than kzalloc() so as not to invoke the !sendpage_ok warning in
skb_splice_from_iter().
(3) Make ceph/rds, skb_send_sock, dlm, nvme, smc, ocfs2, drbd and iscsi
use sendmsg(), not sendpage and make them specify MSG_MORE instead of
MSG_SENDPAGE_NOTLAST.
(4) Kill off sendpage and clean up MSG_SENDPAGE_NOTLAST.

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned
up. Things were converted to use MSG_MORE instead, but the protocol
sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now
unnecessary.

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.

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.

run_tests() accepts too many optional parameters. Before this modification,
it was required to set all of then when only the last one had to be
changed. That's not clear to see all these 0 and it makes the maintenance
harder:
run_tests $ns1 $ns2 10.0.1.1 1 2 3 slow
Instead, the parameter can be set as an env var with a limited scope:
foo=1 bar=2 next=3 \
run_tests $ns1 $ns2 10.0.1.1 slow
This patch switches to key/value "test_linkfail=*" instead of positional
parameter test_linkfail of do_transfer() and run_tests().

New MPTCP info are being checked in multiple places to improve the code
coverage when using the userspace PM.
This patch makes chk_mptcp_info() more generic to be able to check
subflows, add_addr_signal and add_addr_accepted info (and even more
later). New arguments are now required to get different infos from the
two namespaces because some counters are specific to the client or the
server.

This patch moves userspace pm tests out of do_transfer(). Move add address
test into a new function userspace_pm_add_addr(), and remove address test
into userspace_pm_rm_sf_addr_ns1(). Move add subflow test into
userspace_pm_add_sf() and remove subflow into
userspace_pm_rm_sf_addr_ns2().

Bartosz Golaszewski says:
====================
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/.

Use the devres variant of stmmac_pltfr_probe() and finally drop the
remove() callback entirely.

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().

Add a variant of stmmac_pltfr_remove() that only frees resources
allocated by stmmac_pltfr_probe() and - unlike stmmac_pltfr_remove() -
does not call stmmac_remove_config_dt().

Implement stmmac_pltfr_probe() which is the logical API counterpart
for stmmac_pltfr_remove(). It calls the platform's init() callback and
then probes the stmmac device.
