From ca42bc4b7bda7c6d68f1cc97c27fc8ff7385c4c7 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 31 Dec 2020 23:23:01 +0000 Subject: sh: fix trivial misannotations Trivial misannotations in * get_user() (__gu_addr is a userland pointer there) * ip_fast_csum() (sum is __wsum, not unsigned int) * csum_and_copy_to_user() (destination is void *, not const void * - mea culpa) * __clear_user() (to is a userland pointer) * several places in kernel/traps_32.c (regs->pc is a userland pointer when regs is a userland pt_regs) * math-emu/math.c: READ() and WRITE() casts of address should be to userland pointer. No changes in code generation and those take care of the majority of noise from sparse on sh builds.
