#     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.
#     
#     Fixes: 3d4247fcc938 ("powerpc/32: Add support of KASAN_VMALLOC")
