sparc64: Fix buggy strlcpy() conversion in ldom_reboot().
Commit 117a0c5fc9c2d06045bd217385b2b39ea426b5a6 ("sparc: kernel: using
strlcpy() instead of strcpy()") added a bug to ldom_reboot in
arch/sparc/kernel/ds.c
- strcpy(full_boot_str + strlen("boot "), boot_command);
+ strlcpy(full_boot_str + strlen("boot "), boot_command,
+ sizeof(full_boot_str + strlen("boot ")));
That last sizeof() expression evaluates to sizeof(size_t) which is
not what was intended.
Also even the corrected:
sizeof(full_boot_str) + strlen("boot ")
is not right as the destination buffer length is just plain
"sizeof(full_boot_str)" and that's what the final argument
should be.
