on 32-bit i386:

drivers/acpi/apei/erst-dbg.c:106: warning: format '%lx' expects type 'long unsigned int', but argument 3 has type 'ssize_t'
erst-dbg.c:(.text+0xede6d): undefined reference to `__get_user_X'

For the __get_user_X() call, in erst-dbg.c::erst_dbg_ioctl():

	case APEI_ERST_CLEAR_RECORD:
		rc = get_user(record_id, (u64 __user *)arg);

-> arch/x86/include/asm/uaccess.h:

#ifdef CONFIG_X86_32
#define __get_user_8(__ret_gu, __val_gu, ptr)				\
		__get_user_x(X, __ret_gu, __val_gu, ptr)
#else
#define __get_user_8(__ret_gu, __val_gu, ptr)				\
		__get_user_x(8, __ret_gu, __val_gu, ptr)
#endif

so is __get_user_8() not supported on X86_32?
or is this something else?
