From: Geert Uytterhoeven <geert@linux-m68k.org> [ Upstream commit 3e07590e7248db951fed6a2039403b5a39010be7 ] Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"), an obfuscated kernel pointer is printed at every boot if debugging is enabled: vdso: 1 text pages at base (____ptrval____) Remove the print completely, as it's useless without the address. Based on commit 0f1bf7e39822476b ("arm64/vdso: don't leak kernel addresses").
