the mapping is:

KERN_PROTECTION_FAILURE EACCES
KERN_NO_SPACE ENOMEM
KERN_INVALID_ARGUMENT EINVAL
KERN_FAILURE various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE ENOMEM

Patch from PR kern/8001, submitted by Rafal Boni.
...
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards. This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.
This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver. I've tested it (briefly) with 'ei' on arm26
as well. In theory, drivers other than 'ix' should follow precisely the
same code paths as before.

Some small optimisations:
...
o Avoid checking cputype when the kernel is built for one cpu variant only.
o In writeback(), don't use bcopy() to write a mere 16 bytes of 16-byte
aligned data; it's much quicker to copy it inline.
