[Qemu-devel] linux-user 32/64 bit mremap() problem

[Vince Weaver]

Hello

This has been discuessed a year ago
  
http://www.nabble.com/linux-user-mmap()-for-32-bit-guest-on-64-bit-host-td12934745.html
  http://osdir.com/ml/linux.ports.x86-64.general/2007-10/msg00007.html
but hasn't really been resolved.

The linux-user mremap() syscall implementation will return a 64-bit value 
when running on a 64-bit machine, even when the architecture being 
simulated is only 32-bits.

Has any progress been made on this issue?  I might try implementing the 
workaround the kernel people suggested.

This actually prevents one of the perlbmk spec2k benchmarks from running 
with sparc32plus emulation on an x86_64 machine.
