Re: [Qemu-devel] [PATCH] Fix TLS support on x86

[Stefan Weil <weil@mail.berlios.de>]

Hi,

I'd like to test user mode emulation on MIPS host.

Do you have newer versions of your patches which match
current CVS HEAD? TLS support is still missing there,
so QEMU user mode emulation is not really usable without
working patches.

Regards
Stefan
