Below is the list of build error/warning regressions/improvements in
v5.5-rc2[1] compared to v5.4[2].
Summarized:
- build errors: +2/-8
- build warnings: +131/-150
JFYI, when comparing v5.5-rc2[1] to v5.5-rc1[3], the summaries are:
- build errors: +0/-0
- build warnings: +57/-73
Happy fixing! ;-)
Thanks to the linux-next team for providing the build service.

The upgrade from gcc 4.6.3 to 81.0 seems to have revealed a potential
issue in get_user() in arch/m68k/include/asm/uaccess_no.h.
#define get_user(x, ptr) \
({ \
int __gu_err = 0; \
typeof(x) __gu_val = 0; \
^^^^^^^^^
This is the type of the destination
switch (sizeof(*(ptr))) { \
case 1: \
__get_user_asm(__gu_err, __gu_val, ptr, b, "=d"); \
break; \
case 2: \
__get_user_asm(__gu_err, __gu_val, ptr, w, "=r"); \
break; \
case 4: \
__get_user_asm(__gu_err, __gu_val, ptr, l, "=r"); \
break; \
case 8: \
memcpy((void *) &__gu_val, ptr, sizeof (*(ptr))); \
break; \
default: \
__gu_val = 0; \
__gu_err = __get_user_bad(); \
break; \
} \
(x) = (typeof(*(ptr))) __gu_val; \
__gu_err; \
})
ext2_ioctl() calls this like
unsigned short rsv_window_size;
if (get_user(rsv_window_size, (int __user *)arg)) { ... }
So a 32-bit value is being copied to an unsigned short value, leading
to the warning (for the memcpy() in the non-taken "case 8" branch).
Fortunately the compiler emits a register move for this, so no real harm
is done:
| fs/ext2/ioctl.c:123: if (get_user(rsv_window_size,
(int __user *)arg))
move.l 48(%sp),%a0 | arg,
#APP
| 123 "fs/ext2/ioctl.c" 1
movel (%a0),%d2 | *arg.32_43, __gu_val
The corresponding code in arch/m68k/include/asm/uaccess_mm.h
uses a temporary __gu_val of the right sized type based on the source
type to avoid this.

Yeah, your right. I will put a change together to fix.
