The UPAGES have not been there since Jan '96, but the hole was preserved
for BSD/OS binary compatability. This has been fixed other ways (%ebx
now has a pointer to PS_STRINGS), and the stack is nowhere near where
it used to be so this hack isn't required anymore.
These drivers were cloned from the ed and ep drivers back in 1994
when PCMCIA cards were a very new thing and we had no other support
for such devices. They treated the PCIC (the chip which controls the
PCCARD slot) as part of their device and generally hacked their way
to success. They have significantly bit-rotted relative to their
ancestor drivers (ed & ep) and they were a dead-end on the evolution
path to proper PCCARD support in FreeBSD.
They have been terminally broken since August 18 where mdodd forgot
them and nobody seems to have missed them enough to fix them since.
I found no outstanding PRs against these drivers.

by the ones it replaces, as well as many DEC/Intel 21143 10/100 cards.
This also completes my quest to convert things to miibus and add
Alpha support.
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

as in NetBSD, but it has slightly different semantics (it already handles
incrementation of p->p_cpticks, and it should handle any calling frequency).

Add MD_ROOT and MD_ROOT_SIZE options to the md driver.
Make the md driver handle MFS_ROOT and MFS_ROOT_SIZE options for compatibility.
Add md driver to GENERIC, PCCARD and LINT.
This is a cleanup which removes the need for some of the worse hacks in
MFS: We really want to have a rootvnode but MFS on a preloaded image
doesn't really have one. md is a true device, so it is less trouble.
This has been tested with make release, and if people remember to add
the "md" pseudo-device to their kernels, PicoBSD should be just fine
as well. If people have no other use for MFS, it can be removed from
the kernel.

Which is actually 'correct' is debatable, but consistency and
following the spec was deemed more important in this case.

Since an osigcontext is smaller, if you check for a valid (much larger sized)
ucontext_t and it fails, we bogusly would reject the osigcontext as per
rev 1.378. Instead, check for osigcontext range validity first, and
ucontext_t later. This unbreaks Netscape.

nobody else can touch the lock while we hold it. Second, it is not
necessary to use a locked cmpexg when locking a lock that we already
hold, for the same reason. These changes will allow MP locks to be used
recursively without impacting performance.
Modify two procedures that are called only by assembly and are already

Historically, the documentation of extended asm was lacking, namely you
should NOT specify the same register as an input, and a clobber.
If the register is clobbered, it should be specified as an output as well,
e.g., by linking input and output through the "number" notation.

In versions up to egcs-1.1.1, the compiler did not even warn about it,
but it was liable to output bad code. Newer egcs are pickier and simply
refuse to swallow such code.
Note, since *addr changes, it needs to be an output operand.
We might be excessive in saying that all memory has changed.

environment variable vfs.root.mountfrom, which is set by the loader

provide fallback mechanisms for systems not using the loader.
A more robust fallback path is also provided, with the last recourse
being to prompt on the console for a root device.
These changes drastically simplify the machine-dependant parts of
the root configuration process. In addition, support for CDROM root
devices has been removed; it was a nasty hack and didn't work.
