fd8e4ebc8c o Move NTOHL() and associated macros into <sys/param.h>. These are
deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the
  source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
  Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

3b7a4c4b1d Resurrect one of the easiest changes from my big include files roll-up
patch from a year ago: give file flags their own type.  This does not
(yet) change the type used by system calls or library functions.
The underlying type was chosen to match what is returned by stat().

9fb2b0d55e Add a few new functions/macros: intr_disable() and intr_restore() to
disable interrupts completely, and stxa_sync(), which performs a store
immediately followed by a membar #Sync with interrupts disabled (this
is needed for writes to diagnostic registers).

6deb695c1d Add initial smp support. This gets as far as allowing the secondary
cpu(s) into the kernel, and sync-ing them up to "kernel" mode so we can
send them ipis, which also work.

Thanks to John Baldwin for providing me with access to the hardware
that made this possible.

62ec4add59 1. Implement an optimization for pmap_remove() and pmap_protect(): if a
substantial fraction of the number of entries of tte's in the tsb
   would need to be looked up, traverse the tsb instead. This is crucial
   in some places, e.g. when swapping out a process, where a certain
   pmap_remove() call would take very long time to complete without this.
2. Implement pmap_qenter_flags(), which will become used later
3. Reactivate the instruction cache flush done when mapping as executable.
   This is required e.g. when executing files via NFS, but is known to
   cause problems on UltraSPARC-IIe CPU's. If you have such a CPU, you
   will need to comment this call out for now.

cbe522d307 Implement user trap delivery as specified by the sparc abi. This provides
an efficient way for the kernel to bounce certain mundane traps back to
userland for handling there.  A user trap handler returns directly to the
trapping user code, rather than going through the kernel again.  Only a
handful of instructions are actually executed in kernel mode.
Implement sysarch(SPARC_UTRAP_INSTALL).
Add code to handle sharing of the user trap table across forks and unsharing
at exec.

This can be used to implement efficient tracking of floating point register
usage in userland, fe by a thread library, and to handle alignment fault
fixups and instruction emulation in userland, for which the code may need
to be different for 32bit and 64bit binaries.

lists.
Fix pmap_track_modified to work for non-kernel pmaps.  This is due to
kernel virtual addresses potentially overlapping with userland addresses.

624eb79821 Remove support for multi level tsbs, making this code much simpler and
much less magic, fragile, broken.  Use ttes rather than sttes.
We still use the replacement scheme used by the original code, which
is pretty cool.

4339fe0983 1. Certain tlb operations need to be atomic, so disable interrupts for
their duration.  This is still only effective as long as they are
   only used in the static kernel.  Code in modules may cause instruction
   faults which makes these break in different ways anyway.
2. Add a load bearing membar #Sync.
3. Add an inline for demapping an entire context.
