Hi All,

I have just finished upgrading the CONFIG_MMU_MAP (aka mmap) patches
written by Piotrek. I have only tested to build the code with
--target-list=i386-softmmu and only on x86 hosts running Linux. I am
able to run Win XP SP2 as guest both with and without mmap
acceleration with the patch.

The changes are not many since the last release by Piotrek, I just
made sure the code applied to CVS of today and yeah, I added some
basic code to support quad-word memory access. It is totally untested
and probably broken right now. Someone please look at part4 of the
patch and verify that I read 32-bit words the right way.

Sorry PowerPC folks, no ppc host support yet. I will port up the ppc
host patches after someone has fixed so ppc compiles cleanly...

The first three parts are simply upgraded versions of the files
v1-part[1-3].patch.gz that Piotrek posted to the list around a month
ago. Part4 contains changes by me.

Enjoy, please report back to the list with problems and benchmarks!
