Chris Zankel e792290be7 Xtensa improvements for 3.17: ... - support highmem on cores with aliasing data cache. Enable highmem on kc705 by default; - simplify addition of new core variants (no need to modify Kconfig / Makefiles); - improve robustness of unaligned access handler and its interaction with window overflow/underflow exception handlers; - deprecate atomic and spill registers syscalls; - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select' statements; - wire up renameat2 syscall. Various fixes: - fix address checks in dma_{alloc,free}_coherent (runtime BUG); - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage); - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss (runtime unrecoverable exception); - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace register clobbering); - fix kernel/user jump out of fast_unaligned (potential runtime unrecoverable exception); - replace termios IOCTL code definitions with constants (userspace build breakage). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT7YTeAAoJEFH5zJH4P6BEnOYQAJ716CslOAM96DyMWilpSHmn y9Ei5UDorzm7Qiqeg3h0t8BafjDKobAAV+9YP29wPXU5+CKCQTWG8u4n+2BjMyM5 4OyG9SiAJnHpTnySiASmvMiG3slL34VXCyDhWMmF2dQ8CX4+GFm7RSHNy62l4fYR x9iySEtZPD7Uv7aKVfUfIPpY926S+kL3mhOUwlDwMEuDJQhS4oqxc+JL1xoG5XwQ qoCjAEDvoyPgSPKg9dmLpAlbhERe20KPD6biraJ3gW/gAvIMxmeC88rybzF01RbL bf5J93UHay5mQhheAz25Gg2k0DoQHgONsnqmlMOgNk0u/hFJGqnz54DONVzBplVR 16VEHdDmUwO5+cuFDyfcZTtU0u0yV9l+Rr+NLUekyxhjVlL7o5648rZufLLBrnNK SQ+ueI3rp1thnHR+L5iB/E+abjGoUK6TsWJGNYvY6kOPArz9OEKHQkFOhEYip9t2 vT7qfz/YKX0dc8ZwCeSwif/haeChHOvuJU2MKqKBz0McwXv7QxcadYR1o3mP87BL Lp9vibaVaBUT9SkZFtNJwEgJ7WeSV5EN1faakATFRR7H/qhMtUDDFRXAZLcGwUV/ yF60YQuFW0jdwKaEtI1TI1zmckFxPxLwfTXWKob+T4E8KE+k5ZXq1Vcl9FoB5pWG Jcxn92MhHKKl7EAXeveo =q9be -----END PGP SIGNATURE----- Merge tag 'xtensa-for-next-20140815' into for_next Xtensa improvements for 3.17: - support highmem on cores with aliasing data cache.
