speed improvements with large file I/O also. caching semantics
and error case handling most likely need revisiting.

This should allow sparc64 to build its ramdiskbin again.

ksyms_init_explicit instead of ksyms_init, as is the case of booting an
i386 kernel using Multiboot.
predictable. This solves a problem that may appear when serving a tmpfs
over NFS: if the server reboots, newly allocated files should have
different file handles; otherwise the remote clients could access files
they were not supposed to touch.
not persistent across reboots but neither are those of MFS, which we are
trying to replace. We should probably warn the user somehow, but not
prevent him doing this if he really wants to.
While here add a "reply" to the code-style change item.
binaries which cast the returned values to 64-bits and fail due to sign
expansion. More details are provided in the big comment in tmpfs.h that
describes how the new tmpfs_dircookie works.
This is a rather ugly hack that shall be fixed with a cleaner solution,
but this resolves the problem in an effective way.
Fixes kern PR/32034.
from RTK_ or rtk_ to RE_ or re_ for maintainability of these sources.
Eventually we should split these files (and struct rtk_softc) into
three elements, rtk(4) specific one, re(4) specific one, and a common
(register definitions, eeprom and multicast functions etc) part.
While here, add a couple of comments around weird definitions.
like Tx underrun.
This should improve performance on such errors.
Handle fifo threshold properly --- actually it did not handled at all.
Note that the Tx Complete interrupts occur only on errors, and ex_txstat()
is not good place to increment sc->tx_succ_ok. Increase the sc->tx_succ_ok
count from 100 to 256, since the ex(4) does busmastering and underruns
should rarely happen in normal operations.
Possibly improve some situation for the hang-on-heavy-load problems,
such as kern/11450 and kern/27096.
