When building the custom i386 libraries for use on amd64 kernels, we can't use the i386_set_ldt() family of routines, because they are not implemented. Instead, use the recently exposed direct access sysarch routines for setting what %fs and %gs point to. Use this for the i386 TLS _set_tp() routine, but only when compiling to run as a 32 bit support binary for amd64 kernels.

.if !defined(COMPAT_32BIT)
Provide stub functions for i386_set_ldt() and i386_get_ldt() even when compiling as an amd64 support binary. They will return EINVAL on an amd64 kernel, but this simplifies other #ifdefs that were getting a bit nasty.

Make getcontext(2) work on i386. It needs a small wrapper in libc otherwise the return from the syscall stub for getcontext will pop off the return value for the caller to the getcontext stub and it will appear as though the setcontext() syscall returned instead of the getcontext(). The same bug exists on amd64, a fix is coming there too. The bug can be demonstrated with this test code fragment: main() { ucontext_t top; if (getcontext(&top) == 0) { write(2, "PING!\n", 6); /* Cause a return value of 1 from getcontext this time */ top.uc_mcontext.mc_eax = 1; setcontext(&top); err(1, "setcontext() returned"); } write(2, "PONG!\n", 6); _exit(0); }

Nearly missed this one. List non-default asm sources in MDASM so that they replace the defaults. For funny or incomplete syscalls, list them in NOASM to stop them from getting built as defaults.

# Don't generate default code for these syscalls:
Classify mmap, lseek, pread, pwrite, truncate, ftruncate as pseudo syscalls, unless WITHOUT_SYSCALL_COMPAT is defined. 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. Approved by: re (kensmith)

Clean up syscall generation in libc by removing HIDDEN_SYSCALLS and treating (almost) all system calls the same way: __sys_foo - actual syscall foo, _foo - weak definitions to __sys_foo Change PSEUDO syscalls (currently only _exit and _getlogin) to be __sys_foo (T) and _foo (W). Add $FreeBSD$ to a few files to satisfy commitprep. Suggested by: bde

Add wrappers for i386_*_ioperm, i386_vm86 so userland code does not have to call sysarch() directly. Added man pages for above, as well as sysarch()
