Subject: [PATCH -next v2 0/2]riscv: some refactorings realted to uaccess and extable

This patchset do some refactorings related to riscv's uaccess and extable,
mainly for the usage of __get/put_user_nocheck() which not distinguish user
access and kernel access.

v1 -> v2: 
  According to Conor's suggestion, split into two logically independent
  patches.

Tong Tiangen (2):
  riscv: uaccess: rename __get/put_user_nocheck to __get/put_mem_nocheck
  riscv: extable: add new extable type EX_TYPE_KACCESS_ERR_ZERO support
