Oh, hm.. Given that it's a fixed address is there a way the compiler can
screw this up in the face of a kernel preemption (theoretical right now for
sparc*)? I don't think so.. None of the fanciness is required then.

return curcpu()->ci_idepth != 0;

I think the best example in our tree at this point is the x86 scheme of deferring the MMU-switch work to points where we're actually about to reference user mappings, eg. returning to user mode, copyin/copyout, etc. -Chuck

thanks for fixing this.
hmm... code was like:
{
return;
foo();
}
it would be nice if we got warnings about this.

Module Name:src Committed By: tsutsui Date: Wed Jan 13 12:43:06 UTC 2010 Modified Files: src/sys/arch/sparc/sparc: auxreg.h Log Message: Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c. A comment in the macro says AUXIO4M_FTC bit is auto-clear, but my two SS20s (including compatible) with 150MHz hyperSPARCs get data_overrun without it, and no bad side effect on SS5 (works with and without this change). Closes PR port-sparc/42516, which is the last one of a bunch of floppy issue on NetBSD/sparc since NetBSD 2.0 days. See http://mail-index.NetBSD.org/port-sparc/2009/12/20/msg000484.html for details.

Good catch - lwp_startup() should only be called at "lwp birth time" (according to Andrew) - we need to review all ports and split the trampolines used. Martin

It used to be in 4.0, but in 5.0 lwp trampoline calls lwp_startup before calling the lwp function. For SA the trampoline used to be used for recycling lwps for upcalls.
