Christophe Leroy af3d0a6869 powerpc/kasan: Fix shadow memory protection with CONFIG_KASAN_VMALLOC ... With CONFIG_KASAN_VMALLOC, new page tables are created at the time shadow memory for vmalloc area is unmapped. If some parts of the page table still have entries to the zero page shadow memory, the entries are wrongly marked RW. With CONFIG_KASAN_VMALLOC, almost the entire kernel address space is managed by KASAN. To make it simple, just create KASAN page tables for the entire kernel space at kasan_init(). That doesn't use much more space, and that's anyway already done for hash platforms.
