If shadowing causes the shadow gmap to get unshadowed, exit early to
prevent an attempt to dereference the parent pointer, which at this
point is NULL.
Opportunistically add some more checks to prevent NULL parents.

Fix _do_shadow_pte() to use the correct pointer (guest pte instead of
nested guest) to set up the new pte.
Add a check to return -EOPNOTSUPP if the mapping for the nested guest
is writeable but the same page in the guest is only read-only.

Introduce a new special softbit for large pages, like already presend
for normal pages, and use it to mark guest mappings that do not have
struct pages.
Whenever a leaf DAT entry becomes dirty, check the special softbit and
only call SetPageDirty() if there is an actual struct page.
Move the logic to mark pages dirty inside _gmap_ptep_xchg() and
_gmap_crstep_xchg_atomic(), to avoid needlessly duplicating the code.

The slow path of the fault handler ultimately called gmap_link(), which
assumed the fault was a major fault, and blindly called dat_link().
In case of minor faults, things were not always handled properly; in
particular the prefix and vsie marker bits were ignored.
Move dat_link() into gmap.c, renaming it accordingly. Once moved, the
new _gmap_link() function will be able to correctly honour the prefix
and vsie markers.
This will cause spurious unshadows in some uncommon cases.

When shadowing a nested guest, a check is performed and no shadowing is
attempted if the nested guest is already shadowed.
The existing check was incomplete; fix it by also checking whether the
leaf DAT table entry in the existing shadow gmap has the same protection
as the one specified in the guest DAT entry.

In practice dat_crstep_xchg() is racy and hard to use correctly. Simply
remove it and replace its uses with dat_crstep_xchg_atomic().
This solves some actual races that lead to system hangs / crashes.

If the guest misbehaves and puts the page tables for its nested guest
inside the memory of the nested guest itself, and the guest and nested
guest are being mapped with large pages, the shadow mapping will
lose synchronization with the actual mapping, since this will cause the
large page with the vsie notification bit to be split, but the
vsie notification bit will not be propagated to the resulting small
pages.
Fix this by propagating the vsie_notif bit from large pages to normal
pages when splitting a large page.

Previously, missing time namespace support in the vDSO meant that time
namespaces needed to be disabled globally. This was expressed in a hard
dependency on the generic vDSO library. This also meant that architectures
without any vDSO or only a stub vDSO could not enable time namespaces.
Now that all architectures using a real vDSO are using the generic library,
that dependency is not necessary anymore.
Remove the dependency and let all architectures enable time namespaces.

Hamoa and Purwa have pretty close thermal zones definitions. The major
difference is that several zones are absent (because of the lack of the

zones from Hamoa, patching them where required.

Add device tree nodes for QPIC SPI NAND flash controller support
on IPQ5332 SoC.
The IPQ5332 SoC includes a QPIC controller that supports SPI NAND flash
devices with hardware ECC capabilities and DMA support through BAM
(Bus Access Manager).

tertiary USB controller
Enable usb-role-switch for the tertiary USB controller on Lemans.
Additionally, add a port node with an HS endpoint so the controller can be
linked through the DT graph to the corresponding connector.
