x86/mm: Don't leak kernel addresses
[ Upstream commit a3151724437f54076cc10bc02b1c4f0003ae36cd ]
Since commit:
ad67b74d2469d9b8 ("printk: hash addresses printed with %p")
at boot "____ptrval____" is printed instead of actual addresses:
found SMP MP-table at [mem 0x000f5cc0-0x000f5ccf] mapped at [(____ptrval____)]
Instead of changing the print to "%px", and leaking a kernel addresses,
just remove the print completely, like in:
071929dbdd865f77 ("arm64: Stop printing the virtual memory layout").
