Unable to handle kernel access at virtual address (ptrval)

Just use %px instead.
Right. That approach was my first attempt. To fix the regression that way
would involve a lot of patches.
# dmesg | grep ptrval
[ 0.320000] macfb: framebuffer at 0xf9001000, mapped to 0x(ptrval), size 234k
[ 0.420000] mac_esp mac_esp.0: esp0: regs[(ptrval):(null)] irq[19]
The original patch says there are 14000 printk values like these.

I've no idea why the crippled %p was not made dependent on a Kconfig
symbol like CONFIG_DEBUG_FOO. Paranoia?
