leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

matthias 5a74618671 The ns32532 has no alignment restrictions. Define ALIGNED_POINTER to 
reflect this.

matthias 781cd59dd4 * Enlarge kernel virtual memory space. The pc532 kernel now runs at 
0xf8000000. When the kernel was running at 0xfe000000, the INSTALL
  kernel would not run on a 32mb machine.

very large blocksize.

cgd 18ec26aa21 add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH, 
execpt without quotes.  meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).

		  The current priority level is now stored
		  in the switch frame by cpu_switch.

pmap.h		* Taken over from i386/include/pmap.h.

psl.h		* Add USERMODE definition

trap.h		* T_INTERRUPT -> T_AST

types.h		* Remove __FORK_BRAINDAMAGE

jtc 71ab4ed9dc KERNEL -> _KERNEL 1995-03-28 18:13:48 +00:00
cgd b8403d582b don't be so quick to cast macro arguments to unsigned; if the 
arguments are really off_t's (e.g. to btodb), then you can lose
information.  This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.
