* xtensa: use buddy allocator for PTE tableKirill A. Shutemov2013-11-151-8/+12
| | | | | | | | | | | | | At the moment xtensa uses slab allocator for PTE table. It doesn't work with enabled split page table lock: slab uses page->slab_cache and page->first_page for its pages. These fields share stroage with page->ptl. Signed-off-by: Kirill A.

* xtensa: move headers files to arch/xtensa/includeChris Zankel2008-11-061-0/+73
Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.
