I will sent a list of optimizations that have been developed during
the last days. Your feedback is much appreciated.
@Paolo: Can you run your tests that you have made for your migration
optimzations that are now upstream against these patches.
Thanks,
Peter
Peter Lieven (9):
move vector definitions to qemu-common.h
add a function to find non-zero content in a buffer
migration: add an indicator for bulk state of ram migration
buffer_is_zero: use vector optimizations if possible
migration: check for dup pages only in bulk stage
migration: use XBZRLE only after bulk stage
bitops: use vector algorithm to optimize find_next_bit()
migration: do not send zero_pages in bulk stage
migration: do not search dirty pages in bulk stage

Your patches were not properly threaded, which makes it hard to review
this series.

I`m sorry for this. I have to optimize the mail sending.
In case anyone wants to test you can checkout branch `migration_optimizations`
from git@github.com:plieven/qemu.git

Your patch series is not properly threaded. Please use git-send-email.
