2018-08-28riscv: tlb: Provide definition of tlb_flush() before including tlb.hWill Deacon
As of commit fd1102f0aade ("mm: mmu_notifier fix for tlb_end_vma"), asm-generic/tlb.h now calls tlb_flush() from a static inline function, so we need to make sure that it's declared before #including the asm-generic header in the arch header.

2017-09-26RISC-V: Atomic and Locking CodePalmer Dabbelt
This contains all the code that directly interfaces with the RISC-V memory model. While this code corforms to the current RISC-V ISA specifications (user 2.2 and priv 1.10), the memory model is somewhat underspecified in those documents. There is a working group that hopes to produce a formal memory model by the end of the year, but my understanding is that the basic definitions we're relying on here won't change significantly.
