compat: provide compat_ptr() on all architectures
In order to avoid needless #ifdef CONFIG_COMPAT checks, move the compat_ptr() definition to linux/compat.h where it can be seen by any file regardless of the architecture. Only s390 needs a special definition, this can use the self-#define trick we have elsewhere. Reviewed-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
