This is certainly required in the uapi header as of this patch, without it all the numbers are wrong when you include the file from user space.
I suppose it can be removed later once the header is replaced with the two generated versions,
-/* Bitmask values returned from kern_features system call. */ -#define KERN_FEATURE_MIXED_MODE_STACK 0x00000001
I'm fairly sure this also needs to remain in the uapi/asm/unistd.h header as a start, so that user space can call the sys_kern_features() system call and interpret its result when only the first patch is applied.
-#ifdef __32bit_syscall_numbers__ -/* Sparc 32-bit only has the "setresuid32", "getresuid32" variants,
- it never had the plain ones and there is no value to adding those
- old versions into the syscall table.
-#define __IGNORE_setresuid -#define __IGNORE_getresuid -#define __IGNORE_setresgid -#define __IGNORE_getresgid -#endif
-/* Sparc doesn't have protection keys. */ -#define __IGNORE_pkey_mprotect -#define __IGNORE_pkey_alloc -#define __IGNORE_pkey_free
This part is fine.
