<asm-ppc/pgtable.h> and <asm-ppc64/pgtable.h> both define the following map of protection bits:
#define __P000 PAGE_NONE #define __P001 PAGE_READONLY_X #define __P010 PAGE_COPY #define __P011 PAGE_COPY_X #define __P100 PAGE_READONLY #define __P101 PAGE_READONLY_X #define __P110 PAGE_COPY #define __P111 PAGE_COPY_X
#define __S000 PAGE_NONE #define __S001 PAGE_READONLY_X #define __S010 PAGE_SHARED #define __S011 PAGE_SHARED_X #define __S100 PAGE_READONLY #define __S101 PAGE_READONLY_X #define __S110 PAGE_SHARED #define __S111 PAGE_SHARED_X
The _X flags seem wrongly placed, as bit 2 is the PROT_EXEC bit, not bit 0. Is the above intentional?
