minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.
This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.
Fix CALL to use _C_LABEL.

use _C_LABEL when calling functions
with the syscall numbers changed.
Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers). __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns. (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
* Remove $Id$ headers.
* Support LIB_SCCS in all files.
* Use local labels where ever possible.
* Use cpufunc.h instead of __asm__ when possible.
* Access labels with _C_LABEL and _ASM_LABEL.
* Always set errno by calling cerror.
* No more FRAME/EMARF.
* No more SVC, use SYSTRAP instead.
* Use "$Masqueraded: as XXX $" to show e.g. memcpy compiled as bcopy.
* Rewrite vfork to work even whith a "real" vfork system call.
* Make cerror take care of _REENTRANT.
SYSTRAP(x): Expands to the code used to call syscall x.
This is used to simplify other macros.
SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall
that can never fail.
RSYSCALL_NOERROR(x): Like RSYSCALL except that "x" is a syscall
that can never fail.
