[Qemu-devel] Patch for kqemu-1.3.0pre5 on Fedora Core 4 x86_64

Hello,

I have just recently joined the list and thought I would share this
simple patch to get kqemu-1.3.0pre5 to compile against the
2.6.16-1.2096_FC4smp kernel. Configure was run as "./configure
--cc=gcc32 --host-cc=gcc". Before the patch the make output was as
follows:

make -C /lib/modules/2.6.16-1.2096_FC4smp/build M=`pwd` modules
make[1]: Entering directory `/usr/src/kernels/2.6.16-1.2096_FC4-smp-x86_64'

I just made a new kqemu release (version 1.3.0pre6). It includes your 
patch and a few other bug fixes.

Well, there is a change log in the archive and here it is:

version 1.3.0pre6:

- compile fix for Linux kernel version >= 2.6.16
- better null LDT handling (aka Plan9 and ReactOS bug)
- moved monitor code to another address (aka win2k 256 MB bug)

FYI, the windows 2000 install blows up right away with -kernel-kqemu on 
an x86_64 host with qemu-system-x86_64 .

an install with kqemu-user seems to be going okay so far

This is a known issue.. if you do the 1st part of the install (the blue screen text mode bit) with 
usermode kqemu.. then when it does its first reboot, shut down the vm and boot it up with 
-kernel-kemu it works fine..

Oh and of course -win2k-hack
