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. # # Fixes: 3d4247fcc938 ("powerpc/32: Add support of KASAN_VMALLOC") # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> #
