In the Linux kernel, the following vulnerability has been resolved:
powerpc/64: Fix the definition of the fixmap area
At the time being, the fixmap area is defined at the top of the address space or just below KASAN.
This definition is not valid for PPC64.
For PPC64, use the top of the I/O space.
Because of circular dependencies, it is not possible to include asm/fixmap.h in asm/book3s/64/pgtable.h , so define a fixed size AREA at the top of the I/O space for fixmap and ensure during build that the size is big enough.
