* Call gdt_init() earlier on.
* Don't bother to check for TSS and LDT descriptors in verr_gdt().
* Nuke the sti special case for trace and breakpoint traps.
* Move some variable declarations into more appropriate locations.
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
finish up incomplete job of moving structure used by bioscall() to
<machine/bioscall.h>, with associated changes in include file strategy,
genassym stuff, etc.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.
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.
* make map and alloc take 'flags' rather than 'cacheable,' for
more flexibility.
* rename BUS_BARRIER_* to BUS_SPACE_BARRIER_*, for consistency.
* rename bus_space_copy_* to bus_space_copy_region_* and make their
defns match the updated spec.
Backward compatibility is provided by defining __BUS_SPACE_COMPAT_OLDDEFS,
which is currently defined by default.
functions (which only work on memory and i/o space) to i386_memio_*,
and make bus_space_* in bus.h be #defines which invoke them. This makes
life easier for people who need to define the all of the bus_space functions
so that they work on spaces other than memory and I/O space. Also, add
an _i386_memio_map function which is like i386_memio_map but doesn't do
the extent map checking or allocation. _i386_memio_map and i386_memio_*
are for use only by machine-dependent code.
* Make it a strict hierarchy. (It was close anyway).
* Add `serial' and rename `softtty' to `softserial'.
* Make soft interrupts a bit less special-case.
