return the last value returned by a nested method call. This violates
the ACPI spec, but is implemented by the Microsoft interpreter, and thus
vendors can (and do) get away with it.
Intel's stance is that this is illegal and should not be supported.
As they put it, however, we have to live in the real world. So go ahead
and implement it.

- Set debugger options for kernel build
- Define some missing functions
- Bring in GCC defines
- Disable the 'wbinvd' macro as it conflicts with our inline
- AcpiGetProcessorID (fetch the ACPI processor ID for a given ACPI_HANDLE)
- AcpiSetSystemSleepState (set the Sx sleeping state, proposed by Intel
but not actually implemented)
o Remove bogus "spurious interrupt" message.
o Ring buffer head and avail were incorrectly calculated.
o Fix fragment count.
o Fix ring entry for single station, default to 16Mbit.
o Don't complain about long frames.
the system would panic when a user's inode quota was exceeded (see
PR 18959 for details). This fixes that problem.

check to see if it has been committed to disk. If it has never
been written, it can be freed immediately. For short lived files
this change allows the same inode to be reused repeatedly.
Similarly, when upgrading a fragment to a larger size, if it
has never been claimed by an inode on disk, it too can be freed
immediately making it available for reuse often in the next slowly
growing block of the same file.
<sys/bio.h>.
<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.
Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.
Still a few bogus uses of struct buf to track down.
