3099056433 Don't include <isa/isavar.h> or compile code depending on it when isa
is not configured.  Including <isa/isavar.h> when it is not used is
harmful as well as bogus, since it includes "isa_if.h" which is not
generated when isa is not configured.

2f7307b35f Replaced the INTRMASK and INTRUNMASK macros by "|" and "&~" operations.
Some interface botches went away, leaving the macros unused outside of
the implementation of interrupt masking, and it was silly for the
implementation to use the macros in only one place each.

b68c18d69f Fixed races accessing the RTC. The races apparently caused
apm_default_resume() to sometimes set a very wrong time.
(1) Accesses to the RTC index and data registers were not atomic enough.
    Interrupts were not masked.  This was only good enough until an
    interrupt handler (rtcintr()) started accessing the RTC in FreeBSD-2.0.
(2) Access to the block of time registers in inittodr() was not atomic
    enough.  inittodr() has 244us to read the time registers.  Interrupts
    were not masked.  This was only good enough until something (apm)
    started calling inittodr() after boot time in FreeBSD-2.0.
The fix for (2) also makes the timecounter update more atomic, although
this is currently unimportant due to the low resolution of the RTC.

903db590c7 Reclaim UPAGES_HOLE (8k) that was chopped out of process address space.
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.

f4febe538d Remove the if_ze and if_zp drivers.
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.

87e31f4b90 Remove the 'ivars' arguement to device_add_child() and
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.

ccda399c72 Retire MFS_ROOT and MFS_ROOT_SIZE options from the MFS implementation.
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

4f8112e204 Fix a confusion between osigcontext and ucontext_t in the previous commit.
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.

1ac9471dbc Optimize two cases in the MP locking code. First, it is not necessary
to use a locked cmpexg when unlocking a lock that we already hold, since
    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
    NOPROF entries to pass a critical argument in %edx instead of on the
    stack, removing a significant amount of code from the critical path
    as a consequence.

d7ffc4c6e0 Fix clobbers so that GENERIC may compile with GCC 2.95.2.
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.
(Beware of lvalues, some local variables needed...)

URL:http://egcs.cygnus.com/faq.html

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.
