There's a currently ad-hoc protocol to hand off the FreeBSD kernel
payload between the loader and the kernel itself when Xen is in the
middle of the picture. Such protocol wasn't very resilient to changes
to the loader itself, because it relied on moving metadata around to
package it using a certain layout. This has proven to be fragile, so
replace it with a more robust version.
The new protocol requires using a xen_header structure that will be
used to pass data between the FreeBSD loader and the FreeBSD kernel
when booting in dom0 mode. At the moment the only data conveyed is the
offset of the start of the module metadata relative to the start of the
module itself.
This is a slightly disruptive change since it also requires a change
to the kernel which is contained in this patch. In order to update
with this change the kernel must be updated before updating the
loader, as described in the handbook. Note this is only required when
booting a FreeBSD/Xen dom0. This change doesn't affect the normal
FreeBSD boot protocol.
This fixes booting FreeBSD/Xen in dom0 mode after
3630506b9d.

This follows select by eleminating the use of filedesc lock.
This is a win for single-threaded processes and a mixed bag for others
as at small concurrency it is faster to take the lock instead of
refing/unrefing each file descriptor.
Nonetheless, removal of shared lock usage is a step towards a
mtx-protected fd table.
Since most select users are single-threaded this avoid a lot of work
in the common case.
For example select of 16 fds (ops/s):
before: 2114536
after: 2991010
This can be used by single-threaded processes which don't share a file
descriptor table to access their file objects without having to
reference them.
For example select consumers tend to match the requirement and have
several file descriptors to inspect.
This tests fork()s, so if there is still data in the stdout buffer on fork
it will print it again in the child process. This was happening in the
CheriBSD CI and caused the test to complain about malformed TAP output.

It's possible when adding a jail that its dying parent comes back to
life. Only allow that to happen when JAIL_DYING is specified. And if
it does happen, call PR_METHOD_CREATE on it.
vfs_cache_lookup() has already done the appropriate VEXEC check, therefore
we must not re-check in VOP_CACHEDLOOKUP.
This fixes O_SEARCH semantics on tmpfs and removes a redundant descent into
VOP_ACCESS() in the common case.

The current uname is branch-cXXXX-gHASH
Three changes to make uname more useful.
1. Move from using git rev-list --count to git rev-lis --count --first-parent
since that gives a better, incrementing number.
2. Report this count as 'nXXXXX' rather than 'cXXXXX' because c is part of
a hash and we've changed the sematnics of XXXXX
3. Remove g to make HASH cut and pastable.
Durting review, #1 & #3 had the largest consensus. There was a diversity of
opinion on #2, but on the whole it was positive so I'll acknowledge the dissent,
but move forward with something seems to have support since the dissent was all
about what letter to use where I chose 'n'.

newer controller have a sparce bus space that can be figured
out by probing the HW. This gives the starting bus number.
When reading the PCI config. space behind the VMD controller,
the offset of the starting bus needs to be subtracted from
the bus being read.
Fixed a bug in which in which not all of the devices
directly attached to the VMD controller would be probed.
On my initial test HW, a switch was found at bus 0, slot 0
and function 0. All of the NVME drives were behind that
switch. Now scan for all slots and functions attached to
bus 0. If a something was found then run attach after the
scan. On detach also go through all slots and functions
on bus 0.

This code implements a version of the devres framework found
working for various iwlwifi use cases and also providing functions
for ttm_page_alloc_dma.c from DRM.
Part of the framework replicates the consumed KPI, while others
are internal helper functions.
In addition the simple devm_k*malloc() consumers were implemented
and kvasprintf() was enhanced to also work for the devm_kasprintf()
case.
Addmittingly lkpi_devm_kmalloc_release() could be avoided but for
the overall understanding of the code and possible memory tracing
it may still be helpful.
Further devsres consumer are implemented for iwlwifi but will follow
later as the main reason for this change is to sort out overlap with
DRM.

In order to implement pci_dev_put() harmonize further code
(which was started in the aforementioned commit) and add kobj
related bits (through the now common lkpifill_pci_dev() code)
to the DRM specific calls without adding the DRM allocated
pci devices to the pci_devices list.
Add a release for the lkpinew_pci_dev() (DRM) case so freeing
will work.
This allows the DRM created devices to use the normal kobj/refcount
logic and work with, e.g., pci_dev_put().
