auditd creates a pidfile so we should use it for status checks.
This also seems to speed up the frequent onestatus checks used in
tests/sys/audit.

Moving the call to zfs_refcount_remove_many() in abd_free() to be called
before any of the ABD free variants are called. This is necessary
because abd_free_gang() adjusts the abd_size for the gang ABD. If the
parent's child references are removed after free'ing the gang ABD the
refcount is not adjusted correctly for the parent's children.

I also removed some stray abd_put() in comments and changed
abd_free_gang_abd() -> abd_free_gang().

duplicated frame.

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 pci_domain_nr() directly return the domain which got set in
lkpifill_pci_dev() in all cases.  This was missed between D27550
and 105a37cac76b971f7a94409fbdc4f508a7e97fa0 .

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().
(For a slightly more detailed code walk see the review).

The upcoming in-kernel implementations for LinuxKPI based on work on
iwlwifi (and other wireless drivers) conflicts in a few places with
the drm-kmod graphics work outside the base system.

In order to transition smoothly extract the conflicting bits.
This included "unaligned" accessor functions, sg_pcopy_from_buffer(),
IS_*() macros (to be further restricted in the future), power management
bits (possibly no longer conflicting with DRM), and other minor changes.

Implement linux firmware KPI compat code.
This includes: request_firmware() request_firmware_nowait(),
request_firmware_direct(), firmware_request_nowarn(),
and release_firmware().

Given we will try to map requested names from natively ported
or full-linuxkpi-using drivers to a firmware(9) auto-loading
name format (.ko file name and image name matching),
we quieten firmware(9) and print success or failure (unless
the _nowarn() version was called) in the linuxkpi implementation.
At the moment we try up-to 4 different naming combinations,
with path stripped, original name, and requested name with '/'
or '.' replaced.

We do not currently defer loading in the "nowait" case.

This was only used when building for ARMv4 or some ARMv5 or when
_STANDALONE is defined. As ARMv4 and ARMv5 support has been removed,
and we only define _STANDALONE in the bootloader where we don't use
this version of memcpy we can remove it.
