Subject: ptrval hiding -- first kernel messages look rather "interesting"
Hi!
v4.17 on n900:
[ 0.000000] Virtual kernel memory layout:
[ 0.000000] vector : 0xffff0000 - 0xffff1000 ( 4 kB)
[ 0.000000] fixmap : 0xffc00000 - 0xfff00000 (3072 kB)
[ 0.000000] vmalloc : 0xd0000000 - 0xff800000 ( 760 MB)
[ 0.000000] lowmem : 0xc0000000 - 0xcff00000 ( 255 MB)
[ 0.000000] pkmap : 0xbfe00000 - 0xc0000000 ( 2 MB)
[ 0.000000] modules : 0xbf000000 - 0xbfe00000 ( 14 MB)
[ 0.000000] .text : 0x(ptrval) - 0x(ptrval) (8160 kB)
[ 0.000000] .init : 0x(ptrval) - 0x(ptrval) (1024 kB)
[ 0.000000] .data : 0x(ptrval) - 0x(ptrval) ( 309 kB)
[ 0.000000] .bss : 0x(ptrval) - 0x(ptrval) ( 333 kB)
[ 0.000000] NR_IRQS: 16, nr_irqs: 16, preallocated irqs: 16
I mean -- security is nice, but perhaps we should adjust the messages
so this does not look like we are making fun of the user?
