Subject: [PATCH v2 0/2] Let illegal access to user-space memory die
Date:   Thu, 3 Dec 2020 14:48:24 +0800

Accesses to user-space memory without calling uaccess routine
leads to hanging in page fault handler. Like arm64, we let it
die earlier in page fault handler.

Changes in v2:
    -Add a die_kernel_fault() helper
    -Split one long line code into two

Eric Lin (2):
  riscv/mm: Introduce a die_kernel_fault() helper function
  riscv/mm: Prevent kernel module to access user memory without uaccess
    routines
