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().
* _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).
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.
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.

Fix strncmp(x, y, 0)
Use unsigned compares for strcmp and memcmp (and bcmp).
Compiles but untested
AFAICT http://h71000.www7.hp.com/doc/72final/4515/4515pro_025.html#4515ch9_146
cmpc3/5 set %r4 and %r5 to zero, It doesn't look as though the procedure
call is set to preserve these, and I doubt that gcc is treating them as
scratch registers - does our vax pcs actually have %r2 and %r3 as scratch regs?
and when MAXDSIZ were increased memcpy() length sometimes were larger
than 64k (like in amap_extend()) All functions now checks the length.
This fixes PR#19968.
Disable the inline string functions and use the C versions instead.

For each, provide default in <bsd.sys.mk> of the form:
TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo
Document all of these in bsd.README.
This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
