The PHY address bit 2 is configured by the LED pin. Attaching a LED
to this pin is not sufficient to guarantee this configuration pin is
correctly read. This leads to some platforms having their PHY at
address 0 and others at address 4.

If there is no phy-handle specified, the FEC driver will scan the PHY
bus for a PHY and use that. Consequently, adding the DT configuration
of the PHY and the phy properties to the FEC driver broke some boards.

Fix this by removing the phy-handle property, and listing two PHY
entries for both possible PHY addresses, so that the DT configuration
for the PHY can be found by the PHY driver.

The Ux500 platforms have some memory carveouts set aside for
communicating with the modem and for the initial secure software
(ISSW). These areas are protected by the memory controller
and will result in an external abort if accessed like common
read/write memory.

On the legacy boot loaders, these were set aside by using
cmdline arguments such as this:

  mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M
  mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M
  hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M
  mem=638M@385M

Reserve the relevant areas in the device tree instead. The
"mali", "hwmem", "mem_ram_console" and the trailing 1MB at the
end of the memory reservations in the list are not relevant for
the upstream kernel as these are nowadays replaced with
upstream technologies such as CMA. The modem and ISSW
reservations are necessary.

This was manifested in a bug that surfaced in response to
commit 7fef431b ("mm/page_alloc: place pages to tail in __free_pages_core()")
which changes the behaviour of memory allocations
in such a way that the platform will sooner run into these
dangerous areas, with "Unhandled fault: imprecise external
abort (0xc06) at 0xb6fd83dc" or similar: the real reason
turns out to be that the PTE is pointing right into one of
the reserved memory areas. We were just lucky until now.

We need to augment the DB8500 and DB8520 SoCs similarly
and also create a new include for the DB9500 used in the
Snowball since this does not have a modem and thus does
not need the modem memory reservation, albeit it needs
the ISSW reservation.

Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node, however when control is
transferred from the middle of the loop, as in the case of a return
or break or goto, there is no decrement thus ultimately resulting in
a memory leak.

When the creator of SQPOLL io_uring dies (i.e. sqo_task), we don't want
its internals like ->files and ->mm to be poked by the SQPOLL task, it
have never been nice and recently got racy. That can happen when the
owner undergoes destruction and SQPOLL tasks tries to submit new
requests in parallel, and so calls io_sq_thread_acquire*().

That patch halts SQPOLL submissions when sqo_task dies by introducing
sqo_dead flag. Once set, the SQPOLL task must not do any submission,
which is synchronised by uring_lock as well as the new flag.

The tricky part is to make sure that disabling always happens, that
means either the ring is discovered by creator's do_exit() -> cancel,
or if the final close() happens before it's done by the creator. The
last is guaranteed by the fact that for SQPOLL the creator task and only
it holds exactly one file note, so either it pins up to do_exit() or
removed by the creator on the final put in flush. (see comments in
uring_flush() around file->f_count == 2).

One more place that can trigger io_sq_thread_acquire_*() is
__io_req_task_submit(). Shoot off requests on sqo_dead there, even
though actually we don't need to. That's because cancellation of
sqo_task should wait for the request before going any further.

note 1: io_disable_sqo_submit() does io_ring_set_wakeup_flag() so the
caller would enter the ring to get an error, but it still doesn't
guarantee that the flag won't be cleared.

note 2: if final __userspace__ close happens not from the creator
task, the file note will pin the ring until the task dies.
