MFC r304931: Follow ABI when calling __error from the ptrace(2) wrapper. MFC r305012: Rewrite ptrace(2) wrappers in C. MFC r305022: Restore the requirement of setting errno to zero before calling ptrace(2). 2014-09-09T22:24:01Z Ian Lepore ian@FreeBSD.org 2014-09-09T22:24:01Z urn:sha1:f5ecef96e2492121afda39ec7a5e9e317c7840b7 In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo). The EABI unwind info requires a .fnend for every .fnstart, and newer binutils will complain about seeing two .fnstart in a row. This change allows newer tools to compile our code. Do not generate unwind info in asm functions if _STANDALONE is defined. The .fnend op causes the assembler to emit RELOC references to unwind support functions that don't exist in libstand.

This makes the statically linked binaries to use fast gettimeofday(2) by forcing the linker to resolve references and providing the neccessary functions.

Because we don't have a COMPAT_FREEBSD1, just use COMPAT_FREEBSD4. Also fix the Linuxolator to build without the setdomainname() routine by just making it call userland_sysctl on kern.domainname. Also replace the setdomainname()'s implementation to use this approach, because we're duplicating code with sysctl_domainname(). I wasn't able to keep these three routines working in our COMPAT_FREEBSD32, because that would require yet another keyword for syscalls.master (COMPAT4+NOPROTO). Because this routine is probably unused already, this won't be a problem in practice. If it turns out to be a problem, we'll just restore this functionality.

The default case will have the .c wrappers still. If you define WITHOUT_SYSCALL_COMPAT, the .c wrappers will go away and libc will make direct syscalls. After 7-stable starts, the direct syscall method will be default.
