Linus Torvalds 05bdb8c90e 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 unrecoverabl exception); - replace termios IOCTL code definitions with constants (userspace build breakage). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJUA2nrAAoJEI9vqH3mFV2sqS4P/j6+wtuPHhvNLmpzlIJ1//OP zr6o4eRC77HDS0ArqFq+mteU8MH2CXoiMOFvUzXSyistSrQyENJ5Mg8f5vY9sqeJ PQtHzBIg7gBpJTiI66n5k+Av65KdcLdz3JE9j1IHXy+Ovlv+BVAOBWfb6Mx59a5i 4rk+ovSrKbAOI50RBL4p/YpCgxu0hdpnpVJ0Ng7ApSXq18o9uxLdgekn11ZJFtob hFgdh4i5Rg+hL+HV8ehE7K5xwxVaqU//dgdbCVB2g3gcNGaDINiEwyJBxWszln4W wKr9kSCnHihSevDNby/AIw01d1HS18wZdIjTn10/jRnz9PzIET14K2lmqaU6+RyC un8EZW3R0jabMMJ7DqKCiLK6Adz+lNuhs4hx7oGNJIuvyILiSrgqVQEDtwTJDNPk 43lcBYVgpaFviP0exMl9AUb12s8aIhN7D9vFguyuV7Rl8vgUIsEhE67CrIjvi2Hp FV4s1+tVylFYCLbBITPtztfDKiJH4WUbaUGmiK27ReE8L7fAU2jicTau31r0L3ca 66FdInbchvl4TgZBi2ndEsVOmqKc7V8o0Xb+Cmgdda5mgZRw5y8KGnSi9I1YhPc0 xNZq1P6W5HcWbH0kFIRtnRJmGJjtHu+T5Z12yZ+o9EmMXfCePtUSUrMq8YkW/lMg tJCSbnosd4z498k7hFHY =mAYX -----END PGP SIGNATURE----- Merge tag 'xtensa-20140830' of git://github.com/czankel/xtensa-linux Pull Xtensa updates from Chris Zankel: "Xtensa improvements for 3.17: - support highmem on cores with aliasing data cache.
