sparc64: Fix buggy strlcpy() conversion in ldom_reboot().
[ Upstream commit 2bd161a605f1f84a5fc8a4fe8410113a94f79355 ] 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.
