ARM: 8896/1: VDSO: Don't leak kernel addresses
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"). Fixes: ad67b74d2469d9b8 ("printk: hash addresses printed with %p") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
