1ba37196a9 Include arch/powerpc/ibm4xx/intr.c only if a particular board actually 
uses the generic 4xx interrupt implementation.
There are some 4xx boards with entirely different interrupt controllers.

a2bed85761 Implement mach_thread_get_state. 
While we are here, try to tag machine dependent functions in header files.
also transformed darwin_ppc_*_state into mach_ppc_*_state, as this is
what they really are (COMPAT_DARWIN is on the top of COMPAT_MACH, not the
other way around)

1995f8d682 Replace an overlooked instance of p->p_nras with LIST_EMPTY(&p->p_raslist). 2003-11-06 08:49:13 +00:00

2ffbd2ab99 Remove p_nras from struct proc - use LIST_EMPTY(&p->p_raslist) instead. 
Remove p_raslock and rename p_lwplock p_lock (one lock is enough).
Simplify window test when adding a ras and correct test on VM_MAXUSER_ADDRESS.
Avoid unpredictable branch in i386 locore.S
(pad fields left in struct proc to avoid kernel bump)

ef56cc40ab Reduce code duplication by adding mi_userret() in sys/userret.h 
containing signal posting, kernel-exit handling and sa_upcall processing.

XXX the pc532, sparc, sparc64 and vax ports should have their
XXX userret() code rearranged to use this.

cac49e5cf0 clear pcb_onfault before calling uvm_fault() and restore it afterward. 
if the fault handler generates a pagefault, we'd like to panic rather
than invoking the onfault handler.

421dd6cc28 Reorganize the way powerpc port install machine specific headers. 
Use <powerpc/oea/bat.h> exclusively and remove <machine/bat.h> and
<powerpc/bat.h>.  Remove unneeded <machine/cpufunc.h>.  To insure
1:1 correspondence of <powerpc/FOO.h> to <machine/FOO.h> include
"../../powerpc/include/Makefile" in "arch/FOO/include/Makefile".
Incororpate <byte_swap.h> into <bswap.h> and then byte_swap.h

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).

9ed3b44b84 Use ksi_signo and ksi_code accessor macros. 2003-10-08 00:40:54 +00:00
thorpej
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.
