Stas Sergeev 407bc16ad1 signals/sigaltstack: Prepare to add new SS_xxx flags ... This patch adds SS_FLAG_BITS - the mask that splits sigaltstack mode values and bit-flags. Since there is no bit-flags yet, the mask is defined to 0. The flags are added by subsequent patches. With every new flag, the mask should have the appropriate bit cleared. This makes sure if some flag is tried on a kernel that doesn't support it, the -EINVAL error will be returned, because such a flag will be treated as an invalid mode rather than the bit-flag. That way the existence of the particular features can be probed at run-time. This change was suggested by Andy Lutomirski: https://lkml.org/lkml/2016/3/6/158 Signed-off-by: Stas Sergeev <stsp@list.ru> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Amanieu d'Antras <amanieu@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.
