Before this GEOM passed bio pointer to transaction start, but not end.
It was irrelevant until devstat(9) got DTrace hooks, that appeared to
provide bio pointer on I/O completion, but not on submission.

The existing names were inherited from arm64, but we should prefer
RISC-V terminology. Change the prefix to SCAUSE, and further change the
names to better match the RISC-V spec and be more consistent with one
another. Also, remove two codes that are not defined for S-mode (machine
and hypervisor ecall).
While here, apply style(9) to some condition checks.

r326145 corrected do_execve() to return EJUSTRETURN upon success so that
important registers are not clobbered. This had the side effect of tapping
out 'failures' for all *execve(2) audit records, which is less than useful
for auditing purposes.
Audit exec returns earlier, where we can know for sure that EJUSTRETURN
translates to success. Note that this unsets TDP_AUDITREC as we commit the
audit record, so the usual audit in the syscall return path will do nothing.

Remove code that supported pre-2011 kernels. CTLTYPE_S64 was defined
in rev 217616. All supported branches have it, so remove its compat
definition as OBE.
I noticed after the review that these shouldn't be static. Remove the
'static' from them, otherwise concurrent calls to warn* might see a
similar but to the original.
When warn() family of functions is being used after err_set_file() has
been set to, for example, /dev/null, errno is being clobbered,
rendering it unreliable after, for example, procstat_getpathname()
when it is supposed to emit a warning. Then the errno is changed to
Inappropriate ioctl for device, destroying the original value (via
calls to fprintf()functions).

PCIe allows for MSI-X BAR to be either dedicated, or MSI-X Table may
be co-located in some functional BAR. In the later case xhci(4) is
unable to allocate active resource for the table because BAR is
already activated.
Handle it by checking for this special case, and not try to alloc
resource if MSI-X BAR is IO.

GNU and Oracle libelf implementations added support for section
compression, intended to reduce the size of DWARF debug info (which
might be an order of magnitude larger than the code).
There are two compressed ELF section formats:
1. Old GNU - sections are renmaed to start with 'z'. Section contains
a magic number, uncompressed size, and compressed data.
2. Oracle and New GNU - compressed sections use the SHF_COMPRESSED flag.
The compression header contains the compression type, uncompressed
size, and uncompressed alignment.
The second style is preferred and this change implements only that one.

The previous scheme for calculating the total size was doing sizeof
on the struct and then adding the wanted space for the buffer.
nc_name is at offset 58 while sizeof(struct namecache) is 64.
With CACHE_PATH_CUTOFF of 39 bytes and 1 byte of padding we were
allocating 104 bytes for the entry and never accounting for the 6
byte padding, wasting that space.
It no longer protects any of tested fields, keeping all the checks racy.
While here make vtryrecycle drop the vnode on its own. Avoids an additional
lock trip.
