and a machine-independent though inefficient InterlockedExchange().
In Windows, InterlockedExchange() appears to be implemented in header
files via inline assembly. I would prefer using an atomic.h macro for
this, but there doesn't seem to be one that just does a plain old
atomic exchange (as opposed to compare and exchange). Also implement
IoSetCancelRoutine(), which is just a macro that uses InterlockedExchange().
Fill in IoBuildSynchronousFsdRequest(), IoBuildAsynchronousFsdRequest()
and IoBuildDeviceIoControlRequest() so that they do something useful,
and add a bunch of #defines to ntoskrnl_var.h to help make these work.
These may require some tweaks later.
a bugfix of clearing the On-Demand flag when going back to 100%. It
has been tested and works on an IBM R32. Note original work done by
Ted Unangst and sobomax@.
the previous one failed and there are more than one plex in the volume.
This could have led to a flood of error messages on the console and
probably a deadlock in certain situations.
return a generic text message instead.
(Someday, I'll track down all the places that
are generating errors but not recording messages. ;-/

Replace -fmemoize-lookups -fsave-memoized with a working example,
-fconserve-space. To quote part of the GCC docs on this option:
"Put uninitialized or runtime-initialized global variables into the
common segment, as C does."

possibility of someone acquiring a VOP LOCK while xlock is held.

IRQ 0 and not an ExtINT pin. The MADT enumerators ignore the PC-AT flag
and ignore overrides that map IRQ 0 to pin 2 when this quirk is present.
- Add a block comment above the quirks to document each quirk so that we
can use more verbose descriptions quirks.

ACPI MADT only does if the PC-AT flag is set), then don't assume that pin 0
on the first I/O APIC is an ExtINT pin. Instead, assume that it is ISA
IRQ 0.
with the kernel compile time option:
options IPFIREWALL_FORWARD_EXTENDED
This option has to be specified in addition to IPFIRWALL_FORWARD.
With this option even packets targeted for an IP address local
to the host can be redirected. All restrictions to ensure proper
behaviour for locally generated packets are turned off. Firewall
rules have to be carefully crafted to make sure that things like
PMTU discovery do not break.
Document the two kernel options.
