This moves the xen_modified_memory call from cpu_physical_memory_map to cpu_physical_memory_unmap because the memory could be migrated before the device model have written to it. But because we need to know the guest address and to avoid rewriting a new function, the call is moved to qemu_invalidate_entry. So this later has to new parameters, the length of the mapping and if it was a write.

Dear all R2.10 WinXP I have a dataset dealing with the way different wheat cultivars build their yield. Wheat ears are organised in spikelets where the spikelets can be numbered from the bottom, with even numbers on one side and odd on the other. I know how many kernels there were in each spikelet after some months spent counting them... Now I want to illustrate the differences between the

Hello, I am working on my thesis and can't really figure out how to produce a reasonable graph from the output from my glm., I could just give the R-output in my results and then discuss them, but it would be more interesting if I could visualise what is going on. My research is how bees react to different fieldmargins, for this I have 4 different types of field margin (A,B,C & D) and
