Pull hardening fixes from Kees Cook:
"Notably, this contains the fix for for the GCC __init mess I created
with the kstack_erase annotations.
- staging: media: atomisp: Fix stack buffer overflow in
gmin_get_var_int().
I was asked to carry this fix, so here it is. :)
- fortify: Fix incorrect reporting of read buffer size
- kstack_erase: Fix missed export of renamed KSTACK_ERASE_CFLAGS
- compiler_types: Provide __no_kstack_erase to disable coverage only
on Clang"
