Subject: kasan: update kasan_global for gcc 7

From: Dmitry Vyukov <[email protected]>

commit 045d599a286bc01daa3510d59272440a17b23c2e upstream.

kasan_global struct is part of compiler/runtime ABI. gcc revision 241983 has added a new field to kasan_global struct. Update kernel definition of kasan_global struct to include the new field.

Without this patch KASAN is broken with gcc 7.
