Normally i2c controller works as master, so slave addr is not needed, or it will impact some slave device (eg. ST NFC chip) i2c accesses, because it has the same i2c address with controller. For example, On the pxa1928 based platform, where PMIC (88pm860) is present @0x30 address on TWSI0 interface, and if we set 0x30 as a slave address in pxa1928 TWSI0 module, all the transactions towards PMIC would go for toss.

Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.2. No area does particularly stand out but we have a two unpleasant ones: - Kernel ptes are marked with a global bit which allows the kernel to share kernel TLB entries between all processes. For this to work both entries of an adjacent even/odd pte pair need to have the global bit set. There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ. For this reason we temporarily do not permit this permission and will map pages with PROT_EXEC | PROT_READ.
