Hello, all.

Hello Oleksandr,

This small patch series are needed to avoid possible hangs during bringing up 
non-boot CPU.
This solution was suggested by Julien Grall and Ian Campbell.

Discussion in Xen project Mailing List:

The first patch introduces a new macro clean_and_invalidate_xen_dcache().
Unlike existing macro clean_xen_dcache() this macro performs clean and 
invalidate dcache.
The second patch replaces clean_xen_dcache() macro by a 
for boot pagetables after cleaning them.

Thanks you for the patch series. While you introduce clean_and_invalidate_xen_dcache, can you modify flush_to_page_ram to call this function?
