Some people are hitting the "mmc: host bridge didn't serialize us." panic as
the bridge is released before the mmc owner is reset.

When matching entries, we should ignore those with a name of '#'. It's
the standard way to skip elements and need to be present to have the
proper offsets to the fields that are observed. No bus has a pnp
attribute of '#' and that is now disallowed for future buses that are
written.

The current code checks the RWX bits are 0 but does not check the V bit
is non-zero, meaning not-yet-allocated L1 entries that are still zero
are regarded as being allocated. This is likely due to copying the arm64
code that checks ATTR_DESC_MASK is L1_TABLE, which emcompasses both the
type and the validity in a single field, and erroneously translating
that to a check of just PTE_RWX being 0 to indicate non-leaf, forgetting
about the V bit. This then results in the following panic:

Instead, we should just check the V bit, as on amd64, and assert that
any valid L1 entries are not leaves, since an L1 leaf would render the
entire range allocated and thus we should not have attempted to map that
VA in the first place.

Noticed because incorrect output specifications lead to false positives

This was added early in the development of the arm64 port when
cpu_switch was just a stub. It should have been removed when cpu_switch

As this hasn't been needed in 7 years we can remove it.

On amd64, add a possibility to activate kernel with staging area in place.
Add 'copy_staging' command to control this. For now, by default the
old mode of copying kernel to 2M phys is retained. It is going to be
changed in several weeks.
On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data
increase after the final size is calculated. Add a new command
'staging_slop' to control its size.
Improve staging area resizing, in particular, reallocate it anew if
we cannot grow it neither down nor up.
