Subject[PATCH v3 0/3] Optimize tlbflush path
Date
This series adds few optimizations to reduce the trap cost in the tlb
flush path. We should only make SBI calls to remote tlb flush only if
absolutely required.

This series is based on Christoph's series:

http://lists.infradead.org/pipermail/linux-riscv/2019-August/006148.html

Changes from v2->v3:
1. Split the patches into smaller one per optimization.

Atish Patra (3):
RISC-V: Issue a local tlbflush if possible.
RISC-V: Issue a tlb page flush if possible
RISC-V: Do not invoke SBI call if cpumask is empty
