a4fcb94b32 Garbage collect NFSMINOFF() from the NFS stack; this unused macro replicates
mbuf-initialisation logic that is best left to centralised mbuf utility
code rather than scattered around the kernel.

566ff71c45 Clarify a diagnostic printf() in the mbuf code: M_EXT doesn't necessarily
imply a cluster is attached; it could also refer to some other sort of
external storage (e.g., an sf_buf).

a76d5e2b8d Invert AHCI_Q_NOBSYRES quirk meaning, waiting for readiness by default.
I gave up to update list of Marvell chips that require this quirk.
The final nail was growing number of PCIe/M.2 SSDs where Marvell chips
have PCI IDs of different vendors.

059046bff7 Roll back r271012 even more aggressively.
I've looked at the GCC sources and I now understand what's going wrong.
THe C11 keywords are simply nonexistent when using C++ mode. They are
marked as C-only in the parser. This is absolutely impractical for
multiple reasons:

- The C11 keywords do not conflict with C++ naming rules. They all start
  with _[A-Z]. There is no reason to make them C-only.

- It makes it practically impossible for people to use these keywords in
  C header files and expect them to work from within C++ sources.

As I said in my previous commit message: GCC is by far the weirdest
compiler that I've ever used.

88f6292fc6 Partially revert r271012.
Incredibly weird: GCC 4.7/4.9 do support the _Noreturn and _Thread_local
keywords, but not during bootstrapping. GCC is by far the weirdest
compiler that I've ever used.

5a07ed0920 use a straight buffer instead of an iov w/ 1 segment... The aesni
driver when it hits a mbuf/iov buffer, it mallocs and copies the data
for processing..  This improves perf by ~8-10% on my machine...

I have thoughts of fixing AES-NI so that it can better handle segmented
buffers, which should help improve IPSEC performance, but that is for
the future...

83e922af4a Separate out PCI attachment from the main AHCI driver. Move checks of
PCI IDs into quirks, which mostly fit (though you'd get no argument
from me that AHCI_Q_SATA1_UNIT0 is oddly specific). Set these quirks
in the PCI attachment. Make some shared functions public so that PCI
and possibly other bus attachments can use them.

The split isn't perfect yet, but it is functional. The split will be
perfected as other bus attachments for AHCI are written.

aac1b9fa39 Allow multiple image activators to run on the same execution by changing
imgp->interpreted to a bitmask instead of, functionally, a bool. Each
imgactivator now requires its own flag in interpreted to indicate whether
or not it has already examined argv[0].

Change imgp->interpreted to an unsigned char to add one extra bit for
future use.

With this change, one can execute a shell script from a 64bit host native
make and still get the binmisc image activator to fire for the script
interpreter.  Prior to this, execution would fail.
