Subject: printk issue - bug?

I wonder if anyone can reproduce this behaviour on other architectures
(this was SH4)?

code is:

printk("PAGE_SIZE is 0x%X\n", PAGE_SIZE);
printk("Offset is 0x%X, PAGE_SIZE is 0x%X, readlen is 0x%X\n", offset,
PAGE_SIZE, readlen)

Output is:

[  162.603348] PAGE_SIZE is 0x1000
[  162.607473] Offset is 0x0, PAGE_SIZE is 0x0, readlen is 0x1000


ie PAGE_SIZE is incorrectly reported in the second printk (these are
consecutive lines of code)

offset is loff_t and readlen is unsigned long.
