We can end up with a domain having no CPUs capable of receiving I/O
interrupts. This can occur, for example, when all APIC IDs in a given
domain are 256 or greater, and we have no IOMMU.
In this case disable per-domain interrupt support, effectively reverting
to the behaviour before commit a48de40bcc ("Only use CPUs in the
domain the device is attached to for default"). This has a performance
impact but at least allows the system to be functional. It is a stop-
gap until we can rely on the presence of an IOMMU on all x86 platforms.
Thanks to AMD for providing the high-thread-count machine I used for
testing this change, and to cperciva for testing on other hardware.

bcmp(3) is implemented as a variant of memcmp(3) and benefits

This changeset adds a baseline implementation of memcmp and bcmp
for amd64. The same code is used for both functions with conditional
code were the behaviour differs (we need more precise output for the
memcmp case).
FreeBSD documents that memcmp returns the difference between the
mismatching characters. Slightly faster code would be possible could
we relax this requirement to the ISO/IEC 9899:1999 requirement of
merely returning a negative/positive integer or zero.
Performance is better than bionic and glibc, except for long strings
were the two are 13% faster. This could be because they use SSE4
ptest which we cannot use in a baseline kernel.

This commit adds a baseline implementation of stpcpy(3) for amd64.
It performs quite well in comparison to the previous scalar implementation
as well as agains bionic and glibc (though glibc is faster for very long
strings). Fiddle with the Makefile to also have strcpy(3) call into the
optimised stpcpy(3) code, fixing an oversight from D9841.

Restructure parts of pctrie code to make it more compatible with the
needs of vm_radix code.
1. End passing function pointers for memory management.
By breaking insertion into two functions, the call for allocating
memory can happen at the top level and be inlined, rather than
happening via an function pointer to a memory allocator.
By changing the remove function slightly, freeing of memory, when
necessary, can happen at the top level and be inlined.
By turning the reclamation code into two functions, one for starting
iteration over to-be-freed nodes and the other continuing it, all the
freeing can happen at the top level and be inlined.
2. Offer a version of remove that does not panic and returns the freed
value (or NULL).
3. Offer a 'replace' operation, to replace one leaf with another that
has the same key.
These are three of the roadblocks that prevent code sharing between
pctrie and vm_radix code.

The method might require resolving and binding symbols, which means
recursing on the bind lock. It is safe to unlock the bind lock,
since we operate on the private object list, and user attempting to
unload an object from the list of not yet fully loaded objects caused
self-inflicted race.
It is similar to how we treat user' init/fini methods.

load.
As a side-effect of this work, dpaa2_buf structure is simplified and
all of the functions to re-seed those buffers are gathered now in
dpaa2_buf.h and .c files; functions to work with channels are
extracted into dpaa2_channel.h and .c files as well.
