Early versions of the VT-d spec mentioned 6-level paging support as a
possible value for the SAGAW capability, but later versions removed it
and SAGAW=0x10 is currently listed as a reserved value.
The 6-level (agaw=64) entry in sagaw_bits is furthermore problematic
with clang15 because the attempted comparison against 1ULL << 64 in
dmar_maxaddr2mgaw() causes the compiler to elide the last iteration
of the initial loop, which bypasses the subsequent logic to find the
greatest HW-supported address width. This results in 5-level paging
always being selected regardless of whether the hardware supports it,
which can result address translation failure due to invalid context-
entry programming.

This change eliminates the struct pmap_pcid array embedded into struct
pmap and sized by MAXCPU, which would bloat with MAXCPU increase. Also
it removes false sharing of cache lines, since the array elements are
mostly locally accessed by corresponding CPUs.

Prior to 590461a4b8 installation of include files was controlled
directly by ${MK_TOOLCHAIN}. 590461a4b8 added an INCLUDES knob
defaulting to YES. Setting WITHOUT_TOOLCHAIN forced it off to retain
existing behaviour.
Decouple them now, as there are reasonable use cases for installing
libraries and include files without a compiler or other tool chain
components.

Closes#14785Closes#14808
Currently when layering the ABD buffer of each split block on top of
an indirect vdev's ZIO ABD we don't specify the split block's ABD.
This results in those ABDs being incorrectly sized by inheriting
the size of their parent ABD which is larger than what each split
block needs.
The above behavior isn't causing any bugs currently but can lead
to unexpected ABD sizes for people analyzing and/or working on
the ZIO codepath. This patch fixes this behavior by properly setting
the ABD size for split block ZIOs.

Add some more sanity checks to make sure we don't march off the end of
the table. Typically, smbios structures are well formed, or Windows
wouldn't boot. Sometimes they aren't, and this at least fails safe.

This code was written on x86 where unaligned accesses were
easy. LinuxBoot running on aarch64 uses mmap of /dev/mem to read the
smbios table. Linux's mapping of this memory doesn't allow the normal
unaligned fixup, so we get a bus error instead. We can't use the more
natural le16dec and friends because they optimize into a single,
unaligned memory load. We don't see this issue on aarch64 UEFI because
memory is mapped such that unaligned accesses are fixed up.

Implement ZFS bootonce protocol. We pass zfs-bootonce=t to the next boot
stage as a command line argument. Unlike zfsboot -> loader handoff in
the BIOS case, we don't use the OS_BOOTONCE_USED. This would require
modifications to loader.efi which would only server to make it more
complicated. Instead, use the command line parsing interface for the
boot1.efi -> loader.efi to pass in the zfs-bootonce kenv that will be
needed by rc.d/zfsbe to activate the BE if boot progresses that far.
