Merge tag 'xtensa-20170807' of git://github.com/jcmvbkbc/linux-xtensa

Pull Xtensa fixes from Max Filippov:

 - use asm-generic instances of asm/param.h and asm/device.h instead of
   exact copies in arch/xtensa/include/asm;

 - fix build error for xtensa cores with aliasing WT cache: define cache
   flushing functions and copy_{to,from}_user_page;

 - add missing EXPORT_SYMBOLs for clear_user_highpage, copy_user_highpage,
   flush_dcache_page, local_flush_cache_range, local_flush_cache_page,
   csum_partial and csum_partial_copy_generic.

* tag 'xtensa-20170807' of git://github.com/jcmvbkbc/linux-xtensa:
  xtensa: mm/cache: add missing EXPORT_SYMBOLs
  xtensa: don't limit csum_partial export by CONFIG_NET
  xtensa: fix cache aliasing handling code for WT cache
  xtensa: remove wrapper header for asm/param.h
  xtensa: remove wrapper header for asm/device.h
