such as __warn_references() and __weak_reference() which are actually
machine dependant. This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.
This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.
For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
when lowering the priority. Do this by simply calling splx(). For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does. This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.
describe NetBSD, rather than 386BSD 0.1.
Removed 386BSD and BDE control word constants, since we don't need and
will never use them. However, The iBCS control word constant is kept,
since we might want to use it in the iBCS binary compatibility code.
* Inline some functions.
* Eliminate redundant calls to pmap_page_index().
* Reduce the number of TLB flushes in accordance with the i386 SSWG.
* Inline pmap_remove() in pmap_remove_all(). (Most if it is unnecessary.)
* Allocate pv_entry's in pages, and keep a list of free entries in each page,
and a list of pages with free entries. (Trying to reduce malloc() overhead,
and improve locality of reference.)
* Remove a couple of macros that aren't really useful.
* Remove pmap_kernel() completely.
architectures:
Renamed _C_FUNC() to _C_LABEL()
Renamed _ASM_FUNC() to _ASM_LABEL()
Merged _BEGIN_ENTRY with _ENTRY
Renamed _END_ENTRY to _PROF_PROLOGUE
When assembling with profiling enabled, set up stack frame before calling
mcount() in _PROF_PROLOGUE. Also omit emitting .long 0's, as they are no
longer used by the profiling code.
