b03d459244 From Ross Harvey: 
- Fix a bug where IPL wasn't being lowered to process SIRs, which
  effectively caused them to be processed at splserial(), and loop
  over the ssir, like we do for astpending.
- Optimize the flow of exception_return().

13c27090e8 Don't call the sc->sbic_dmago() function if the data length is zero. 
This avoids a zero pointer dereference, which fixes PR 8571.
Make sbic_dmago() report selection timeouts to the upper layer.
This makes sbic really work again with 1.4L.

f3055da377 Simple little speed hack in pmap_is_referenced()/pmap_is_modified(): don't 
need to have the pv_head lock in order to test the REFERENCED or MODIFIED
attribute; the load of `pvh_attrs' is atomic.

79a1245dbb - Fix a case where we weren't acquiring the pv_head lock when modifying 
the page attributes in pmap_enter().
- It's no longer necessary (and hasn't been for a while in this pmap) to
  go to splimp() to use the physical->virtual table, so remove all such
  uses.

6bb1df8224 Fix a race condition in AST processing described by Andrew Gallatin on 
the freebsd-alpha mailing list which basically boiled down to increasing
stack depth due to lowering the IPL before checking for an AST.

This changes AST processing to do basically what the i386 port does (as
described by Charles Hannum):

 check_ast:
        if (astpending) {
                lower IPL
                process AST
                raise IPL
                goto check_ast
        }

c9c2181ed9 provide an __ELF__ version of _C_FUNC and _C_LABEL, convert the assembly 
#defines in asm.h to use them, and convert code which needs to use C labels
to use _C_LABEL as well.  (I can't see any reason why the label vs. function
differentiation shouldn't be GC'd; i only added uses of _C_LABEL.)  This
should help if this port is converted to use ELF, and was checked by
compiling all kernels in arm32/conf (with some driver removals and some
MI header fixups re: common blocks) with an arm-linux ELF toolchain.

e5f51da9de -mask interrupts w/o a handler 
-update PIC _after_ the interrupt handler is linked into the chain
This fixes problems with dynamically installed interrupt handlers:
Interrupts were enabled before the handler was installed under some
circumstances (esp. on faster machines), leading to endless interrupt
handling.
