6e204ff9bc Fix previous (bzero -> memset), it overlooked the delay slot. 
Use set and clr pseudo instructions to simplify the code a bit.

deb5638bdc Adapt to MI mk48txx(4) changes. 
Tested on SS1+ (mainbus), but not tested on sun4/sun4m (obio).

XXX maybe this file should be split into mainbus and obio attachments
XXX and moved into sys/arch/sparc/dev or sys/dev/sun.

b936d40f39 Avoid sneaking past signal delivery in sa_upcall_userret(): 
generate unblocked upcalls in sa_unblock_userret(), before signal
delivery/p_userret handling in userret().

Also defer getting state for preempted upcalls because on some ports
preemption can happen between sa_unblock_userret() and sa_upcall_userret().

Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

901da40cf9 Add some accessor macros for the ucontext: 
* _UC_MACHINE_PC() - access the program counter
* _UC_MACHINE_INTRV() - access the integer return value register
* _UC_MACHINE_SET_PC() - set the program counter (this requires
  special handling on some platforms).

68723a995b * Shuffle some data structures so, and add a flags word to ksiginfo_t. 
Right now the only flag is used to indicate if a ksiginfo_t is a
  result of a trap.  Add a predicate macro to test for this flag.
* Add initialization macros for ksiginfo_t's.
* Add accssor macro for ksi_trap.  Expands to 0 if the ksiginfo_t was
  not the result of a trap.  This matches the sigcontext trapcode semantics.
* In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal.
  Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles
  the case of non-trap-generated signals that have a > 0 si_code.

This patch fixes a signal delivery problem with threaded programs noted by
Matthias Drochner on tech-kern.

As discussed on tech-kern.  Reviewed and OK's by Christos.

e6286b949a Add some framework for MI assignment of device majors - add sys/dev/majors 
which is automatically included during kernel config, and add comments
to individual machine-dependant majors.* files to assign new MI majors
in MI file.

Range 0-191 is reserved for machine-specific assignments, range
192+ are MI assignments.
