ptrdiff_t, size_t and long are the same size on all supported architectures,
but gcc requires the use of the %zx modifier instead of %lx. On 32-bit
targets, the wrong one produces this warning:
drivers/gpu/drm/xe/xe_lrc.c:1913:7: error: format specifies type 'unsigned long' but the argument has type '__ptrdiff_t' (aka 'int') [-Werror,-Wformat]

Nathan Chancellor just sent a fix here:
https://lore.kernel.org/all/20260316-drm-xe-fix-32-bit-wformat-ptrdiff-v1-1-0108b10b2b6b@kernel.org/
His solution uses %tx rather than %zx, which according to
Documentation/core-api/printk-formats.rst sounds like it's probably the
most accurate format string for this case?

Right, Nathan's version is correct. I wasn't aware that size_t
and ptrdiff_t have different modifiers.

Consider:
void foo(size_t len)
{
char *p = malloc(len);
char *end = p + len;
ptrdiff_t diff = p - end;
printf("len %zu, diff %td\n", len, diff);
free(p);
}
Clearly foo(5) output "5 -5".
But what about foo(5u << 29) on a 32bit system with a large unlimit and
a big enough hole in the address space.
More likely would be something running on an x86 in real mode.
There malloc(65000) might be reasonable, so size_t would be unsigned int
but ptrdiff_t would need to be a signed 32bit type.
Of course, in linux, they are all 'long'.

I should have said 'the same size as long'.
