Alan Kao ebcbd75e39 riscv: Fix the bug in memory access fixup code ... A piece of fixup code is currently shared by __copy_user and __clear_user. It first disables the access to user-space memory and then returns the "n" argument, which represents #(bytes not processed). However,__copy_user's "n" is in register a2, while __clear_user's in a1, and thus it causes errors for programs like setdomainname02 testcase in LTP. This patch fixes this issue by separating their fixup code and returning the right value for the kernel to handle a relative fault properly.
