0191e03a4e Update for AMD64 after repocopy from i386/sys/*. This means:
- strip out the nasty PIC_PROLOGUE/EPILOGUE stuff, since we dont have
to lose a register in PIC mode anymore (we use %rip-relative addressing).
- update for C register argument passing conventions.
- convert 32 bit to 64 bit register sizes etc.

4dbb9c65d7 Update for AMD64-style syscalls. Repocopied from i386/SYS.h.
Note that the syscall instruction clobbers %rcx, which is inconvenient
because it is the fourth syscall argument, so we use %r10 (another scratch
register) for the 4th syscall arg instead (I picked %r10 to be the same as
NetBSD).  int 0x80 is still possible though, and it uses %rcx as usual.
Note that the syscall style syscall does *NOT* preserve all the registers,
unlike int 0x80.  We do not preserve the scratch registers except for
%rdi and %rsi.  int 0x80 does preserve everything but the return values.

e2527daf1a In compat mode, we `redispatch' the lookup. It is probably a good
idea to re-initialize `struct passwd', because e.g. pw_class might
get set by one module, but not by another.  Add another call to the
internal pwd_init function to accomplish this.

Correct a bug that should have wreaked havoc everywhere, but for
some reason only bit unlucky people who use `-march' optimizations.
The compiler cannot assist one in distinguishing between the two
function calls below.

An incorrectly-sized allocation was being made due to an incorrect

`foo = malloc(sizeof(*foo))' idiom.  Hard-to-see, because it was a

4c3c0fecae Don't use `memset' to initialize a struct passwd. A module
may not fill in all fields, and in the case of string fields, this could
cause trouble for applications.  (The only likely example is `pw_class',
because this field is not used by all modules in all cases.)

Move initialization of struct passwd from module-specific code to the
dispatch code.
