0af805cb7d Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This 
bug only affected FPU emulators.  It might have caused bogus FPU states
in core dumps and in the child pcb after a fork.  Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.

Cleaned up #includes.

8c536fe336 Gag! Somebody removed the bus mouse from GENERIC for reasons unknown. 
That certainly explains why I noticed it suddenly missing from the

6b740ac6e9 Add a lock for DMA Channels to prevent two devices from using the same DMA 
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

ceb23bccb6 Fixed a problem that the UPAGES of a process were being run down 
in a suboptimal manner.  I had also noticed some panics that appeared
to be at least superficially caused by this problem.  Also, included
are some minor mods to support more general handling of page table page
faulting.  More details in a future commit.

b26bbde39a Moved rtcin() to clock.c. 
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable.  It only needs
to be fast in rtcintr().

cbb78b9a73 Add support for Pentium and Pentium Pro performance counters. 
(This code is as yet untested; to come after man page is written.)
This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC
instructions.  The user-mode interface is via a subdevice of mem.c;
there is also a kernel-size interface which might be used to aid
profiling.
