[Xen-devel] [PATCH v1 0/2] Clean and invalidate dcache for boot pagetables during setup



Hello, all.

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:
http://lists.xen.org/archives/html/xen-devel/2014-02/msg01575.html

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 
clean_and_invalidate_xen_dcache()
for boot pagetables after cleaning them.

This patch series was tested on DRA7 platform manufactured by TI.
